The general population may be exposed by vapors, dermal contact and consumption of food flavored with Isobornyl acetate (izobornil asetat, isobornyl acetate). If Isobornyl acetate (izobornil asetat, isobornyl acetate) is released to the environment, it will be broken down in air. It is not expected to be broken down by sunlight. It will move into air from moist soil and water surfaces. It is expected to move through soil. It will be broken down by microorganisms, and is expected to build up in fish. RISK: Allergic skin reactions were not observed in volunteers following direct skin exposure. Other data on the potential for Isobornyl acetate (izobornil asetat, isobornyl acetate) to produce toxic effects in humans were not available. Isobornyl acetate (izobornil asetat, isobornyl acetate) is a mild skin irritant in laboratory animals. Kidney and liver damage and changes in kidney function were reported in laboratory animals following repeated exposure to moderate-to-high oral doses of Isobornyl acetate (izobornil asetat, isobornyl acetate) over time.

Data on the potential for Isobornyl acetate (izobornil asetat, isobornyl acetate) to cause cancer in laboratory animals were not available. The potential for Isobornyl acetate (izobornil asetat, isobornyl acetate) to cause cancer in humans has not been assessed by the U.S. EPA IRIS program, the International Agency for Research on Cancer, or the U.S. National Toxicology Program 14th Report on Carcinogens. For Isobornyl acetate (izobornil asetat, isobornyl acetate) (USEPA/OPP Pesticide Code: 128875) there are 0 labels match. /SRP: Not registered for current use in the USA, but approved pesticide uses may change periodically and so federal, state and local authorities must be consulted for currently approved uses. Isobornyl acetate (izobornil asetat, isobornyl acetate) is used in large amounts for perfuming soap, bath products, and air fresheners. However, the major use of Isobornyl acetate (izobornil asetat, isobornyl acetate) is as an intermediate in the production of camphor. Isobornyl acetate (izobornil asetat, isobornyl acetate) is prepared from camphene and acetic acid in the presence of acidic catalysts (e.g., sulfuric acid), or on a styrene-divinylbenzene acid ion-exchanger. Residues of Isobornyl acetate (izobornil asetat, isobornyl acetate) are exempted from the requirement of a tolerance when used in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops only. IDENTIFICATION AND USE: Isobornyl acetate (izobornil asetat, isobornyl acetate) is used in soaps, detergents, creams and lotions and perfumes. HUMAN STUDIES: A maximization test was carried out on 25 volunteers. The material was tested at a concentration of 10% and produced no sensitization reactions. ANIMAL STUDIES: Isobornyl acetate (izobornil asetat, isobornyl acetate) applied full strength to intact or abraded rabbit skin for 24 hr under occlusion was mildly irritating. Isobornyl acetate (izobornil asetat, isobornyl acetate) was administered daily to rats in doses of 0, 15, 90 or 270 mg/kg bw for 13 wk. Male rats had signs of nephrotoxicity at 90 mg/kg and 270 mg/kg/day, as well as signs of hepatotoxicity at 270 mg/kg. Isobornyl acetate (izobornil asetat, isobornyl acetate) was investigated in a 1-generation reproduction study in rats and it did not produce developmental toxicity. Increased incidences of excess salivation occurred in parent generation male and female rats at 100 and/or 300 mg/kg/d throughout the dosage period, and low incidences of urine-stained abdominal fur were seen in females at 300 mg/kg/d during the gestation period. Isobornyl acetate (izobornil asetat, isobornyl acetate)'s production and use in toilet waters, bath preparations, antiseptics, soaps, making synthetic camphor and as a flavoring agent may result in its release to the environment through various waste streams. Its use in compounding needle odors and theater sprays will result in its direct release to the environment. Isobornyl acetate (izobornil asetat, isobornyl acetate) is reported in a wide variety of herbs and other plants. If released to air, an estimated vapor pressure of 0.11 mm Hg at 25 °C indicates Isobornyl acetate (izobornil asetat, isobornyl acetate) will exist solely as a vapor in the atmosphere. Vapor-phase Isobornyl acetate (izobornil asetat, isobornyl acetate) will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 50 hrs. Isobornyl acetate (izobornil asetat, isobornyl acetate) does not contain chromophores that absorb at wavelengths >290 nm and, therefore, is not expected to be susceptible to direct photolysis by sunlight. If released to soil, Isobornyl acetate (izobornil asetat, isobornyl acetate) is expected to have moderate mobility based upon an estimated Koc of 420. Volatilization from moist soil surfaces is expected to be an important fate process based upon an estimated Henry's Law constant of 9.5X10-5 atm-cu m/mole. Isobornyl acetate (izobornil asetat, isobornyl acetate) has an estimated vapor pressure of 0.11 mm Hg and exists as a liquid under environmental conditions; therefore, Isobornyl acetate (izobornil asetat, isobornyl acetate) may volatilize from dry soil. Using the OECD Biodegradability test, isoborneol acetate was biodegraded in 10 days, suggesting that biodegradation is an important environment fate process in soil or water. If released into water, Isobornyl acetate (izobornil asetat, isobornyl acetate) is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's estimated Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 17 hrs and 9.5 days, respectively. An estimated BCF of 320 suggests the potential for bioconcentration in aquatic organisms is moderate. Hydrolysis is not expected to be an important environmental fate process as indicated by estimated base-catalyzed second-order half-lives of 2.3 yrs and 84 days at pH values of 7 and 8, respectively. Occupational exposure to Isobornyl acetate (izobornil asetat, isobornyl acetate) may occur through inhalation and dermal contact with this compound at workplaces where Isobornyl acetate (izobornil asetat, isobornyl acetate) is produced or used. Monitoring data indicate that the general population may be exposed to Isobornyl acetate (izobornil asetat, isobornyl acetate) via inhalation of ambient air, ingestion of food, and dermal contact with consumer products containing Isobornyl acetate (izobornil asetat, isobornyl acetate). Isobornyl acetate (izobornil asetat, isobornyl acetate) is reported in a wide variety of herbs and other plants(1). It is a natural emmission from pine and fir trees(2). The compound is reported as occurring in thymus, Parmesan cheese, dill herb, Ocimum basilicum, rosemary and custard apple(3). Isobornyl acetate (izobornil asetat, isobornyl acetate)'s production and use in toilet waters, bath preparations, antiseptics, soaps, making synthetic camphor(1) and as a flavoring agent(1,2) may result in its release to the environment through various waste streams. Its use in compounding pine needle odors and theater sprays(1) will result in its direct release to the environment(SRC). TERRESTRIAL FATE: Based on a classification scheme(1), an estimated Koc value of 420(SRC), determined from a structure estimation method(2), indicates that Isobornyl acetate (izobornil asetat, isobornyl acetate) is expected to have moderate mobility in soil(SRC). Volatilization of Isobornyl acetate (izobornil asetat, isobornyl acetate) from moist soil surfaces is expected to be an important fate process(SRC) given an estimated Henry's Law constant of 9.5X10-5 atm-cu m/mole(SRC), developed using a fragment constant estimation method(2). Isobornyl acetate (izobornil asetat, isobornyl acetate) has an estimated vapor pressure of 0.11 mm Hg(2) and exists as a liquid under environmental conditions; therefore, Isobornyl acetate (izobornil asetat, isobornyl acetate) may volatilize from dry soil. Using the OECD Biodegradability test, isoborneol acetate was biodegraded in 10 days(3), suggesting that biodegradation is an important environment fate process in soil(SRC). ATMOSPHERIC FATE: According to a model of gas/particle partitioning of semivolatile organic compounds in the atmosphere(1), Isobornyl acetate (izobornil asetat, isobornyl acetate), which has an estimated vapor pressure of 0.11 mm Hg at 25 °C(SRC), determined from a fragment constant method(2), is expected to exist solely as a vapor in the ambient atmosphere. Vapor-phase Isobornyl acetate (izobornil asetat, isobornyl acetate) is degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals(SRC); the half-life for this reaction in air is estimated to be 50 hrs(SRC), calculated from its rate constant of 7.7X10-12 cu cm/molecule-sec at 25 °C(SRC) that was derived using a structure estimation method(2). Isobornyl acetate (izobornil asetat, isobornyl acetate) does not contain chromophores that absorb at wavelengths >290 nm(3) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). AEROBIC: Isobornyl acetate (izobornil asetat, isobornyl acetate) was biodegraded in 10 days in the OECD Ready Biodegradability test. The compound was 29.0 and 99.8% removed in wastewater treat plants under primary gravitational settling and activated sludge treatement process, respectively(1). The rate constant for the vapor-phase reaction of Isobornyl acetate (izobornil asetat, isobornyl acetate) with photochemically-produced hydroxyl radicals has been estimated as 7.7X10-12 cu cm/molecule-sec at 25 °C(SRC) using a structure estimation method(1). This corresponds to an atmospheric half-life of about 50 hours at an atmospheric concentration of 5X10+5 hydroxyl radicals per cu cm(1). A base-catalyzed second-order hydrolysis rate constant of 9.5X10-2 L/mole-sec(SRC) was estimated using a structure estimation method(1); this corresponds to half-lives of 2.3 yrs and 84 days at pH values of 7 and 8, respectively(1). Isobornyl acetate (izobornil asetat, isobornyl acetate) does not contain chromophores that absorb at wavelengths >290 nm(2) and, therefore, is not expected to be susceptible to direct photolysis by sunlight(SRC). An estimated BCF of 320 was calculated in fish for Isobornyl acetate (izobornil asetat, isobornyl acetate)(SRC), using a log Kow of 4.30(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is high(SRC). Using a structure estimation method based on molecular connectivity indices(1), the Koc of Isobornyl acetate (izobornil asetat, isobornyl acetate) can be estimated to be 420(SRC). According to a classification scheme(2), this estimated Koc value suggests that Isobornyl acetate (izobornil asetat, isobornyl acetate) is expected to moderate mobility in soil(SRC). Isobornyl acetate (izobornil asetat, isobornyl acetate) readily hydrolyzes (within hours) to isobornyl alcohol during the first step of its biochemical pathway.

As its name indicates, it is a major component of the oil from the fruit of oil palms (palm oil). Palmitic acid can also be found in meats, cheeses, butter, and other dairy products. Palmitates are the salts and esters of ISOCETYL PALMITATE (İzosetil Palmitat). The palmitate anion is the observed form of ISOCETYL PALMITATE (İzosetil Palmitat) at physiologic pH (7.4).Aluminium salts of ISOCETYL PALMITATE (İzosetil Palmitat) and naphthenic acid were combined during World War II to produce napalm. The word "napalm" is derived from the words naphthenic acid and ISOCETYL PALMITATE (İzosetil Palmitat).Palmitic acid was discovered by Edmond Frémy in 1840, in saponified palm oil.This remains the primary industrial route for its production, with the triglycerides (fats) in palm oil being hydrolysed by high temperature water (above 200 °C or 390 °F), and the resulting mixture fractionally distilled to give the pure product.Palmitic acid is naturally produced by a wide range of other plants and organisms, typically at low levels. It is naturally present in butter, cheese, milk, and meat, as well as cocoa butter, soybean oil, and sunflower oil. Karukas contain 44.90% ISOCETYL PALMITATE (İzosetil Palmitat).The cetyl ester of ISOCETYL PALMITATE (İzosetil Palmitat) (cetyl palmitate) occurs in spermaceti.Excess carbohydrates in the body are converted to ISOCETYL PALMITATE (İzosetil Palmitat). Palmitic acid is the first fatty acid produced during fatty acid synthesis and is the precursor to longer fatty acids. As a consequence, ISOCETYL PALMITATE (İzosetil Palmitat) is a major body component of animals. In humans, one analysis found it to make up 21–30% (molar) of human depot fat, and it is a major, but highly variable, lipid component of human breast milk. Palmitate negatively feeds back on acetyl-CoA carboxylase (ACC), which is responsible for converting acetyl-CoA to malonyl-CoA, which in turn is used to add to the growing acyl chain, thus preventing further palmitate generation.In biology, some proteins are modified by the addition of a palmitoyl group in a process known as palmitoylation. Palmitoylation is important for membrane localisation of many proteins.Palmitic acid is used to produce soaps, cosmetics, and industrial mold release agents. These applications use sodium palmitate, which is commonly obtained by saponification of palm oil. To this end, palm oil, rendered from palm tree (species Elaeis guineensis), is treated with sodium hydroxide (in the form of caustic soda or lye), which causes hydrolysis of the ester groups, yielding glycerol and sodium palmitate.Because it is inexpensive and adds texture and "mouth feel" to processed foods (convenience food), ISOCETYL PALMITATE (İzosetil Palmitat) and its sodium salt find wide use in foodstuffs. Sodium palmitate is permitted as a natural additive in organic products.The aluminium salt is used as a thickening agent of napalm used in military actions.Hydrogenation of ISOCETYL PALMITATE (İzosetil Palmitat) yields cetyl alcohol, which is used to produce detergents and cosmetics.Recently, a long-acting antipsychotic medication, paliperidone palmitate (marketed as INVEGA Sustenna), used in the treatment of schizophrenia, has been synthesized using the oily palmitate ester as a long-acting release carrier medium when injected intramuscularly. The underlying method of drug delivery is similar to that used with decanoic acid to deliver long-acting depot medication, in particular, neuroleptics such as haloperidol decanoate.According to the World Health Organization, evidence is "convincing" that consumption of ISOCETYL PALMITATE (İzosetil Palmitat) increases the risk of developing cardiovascular disease,based on studies indicating that it may increase LDL levels in the blood. Retinyl palmitate is a source of vitamin A added to low-fat milk to replace the vitamin content lost through the removal of milk fat. Palmitate is attached to the alcohol form of vitamin A, retinol, to make vitamin A stable in milk.Treatment of commercially available 2-(decyl)dodecanoic acid or 2-(tetradecyl)ISOCETYL PALMITATE (İzosetil Palmitat) (37) in methanol in the presence of concd sulfuric acid gave the methyl ester 38 in a quantitative yield. In the essentially same way, 3-(nonyl)dodecanoic acid or 3-(tridecyl)ISOCETYL PALMITATE (İzosetil Palmitat) (40) gave the corresponding methyl esters 41 in almost quantitative yields. Reduction of the methyl esters with LiAlH4 in dry ether gave the corresponding alcohols 39 and 42 in good yields, respectively (Scheme 8).11The homologous series with n = 5 and m = 7 includes cis-9,10-methylene-hexadecanoic acid, and the homologous series with n = 5 and m = 9 includes lactobacillic acid (cis-11,12-methylene-octadecanoic acid). The homologous series with n = 7 and m = 6 includes dihydromalvalic acid (systematic name: 2-octyl-cyclopropaneheptanoic acid), and the homologous series with n = 7 and m = 7 includes dihydrosterculic acid (systematic name: cis-9,10-methylene-octadecanoic acid), see Fig. 6.Experimental Hf data (Table A3) in the range of n-heptanoic acid (nC= 7) and ISOCETYL PALMITATE (İzosetil Palmitat) (nC= 16) were used as the training set for deriving a QPPR of the form of Eq. 3 for the n-alkanoic acid series. The uncertainty level for the data ranges between <0.2% to <3%. The resultant parameter values obtained: B0= (3.461 ± 0.076) × 107 and B1= 1.005525 ± 0.026 with a correlation coefficient R2= 0.998967 and a randomly distributed residual plot (Fig. A3). As in the case of the n-mercaptans, the value of B1 is essentially 1.Essential oils are principal components of the leaves of fenugreek with main compounds as (2E)-hexenal (26.61%), ISOCETYL PALMITATE (İzosetil Palmitat) (10.14%) and (E)-β-ionone (7.99%) among others (Riasat et al., 2017). These fragrant molecules are however not the major constituent of the seeds and are not herein addressed as the pharmacologically relevant constituents. In one particular analysis study by Shahinuzzaman et al. (2015), the essential oil constituents of fenugreek seeds were shown to contain fatty acids as major components: decane, 5,6-bis(2,2-dimethylpropylidene)-, (E,Z)- (19.58%), ISOCETYL PALMITATE (İzosetil Palmitat), methyl ester (18.81%) and dihydro methyl jasmonate (10.99%) (Table 17.1). Hence fatty acids and derivatives are the major essential oil components of fenugreek seeds.The content of essential oils of Centaurea species are characterized by the presence of sesquiterpenes skeleton (caryophyllene, eudesmol and germacrene); hydracarbons (tricosane, pentacosane and heptacosane); fatty acids (ISOCETYL PALMITATE (İzosetil Palmitat), tetradecanoic acid, and dodecanoic acid) and monoterpenes (aspinene, terpinene and carvacrol).Common names of fatty acids are more often used than the IUPAC names (Table 31.1). The most common saturated fatty acids, palmitic and stearic acids, contain 16 and 18 carbon atoms, respectively. Their IUPAC names are ISOCETYL PALMITATE (İzosetil Palmitat) and octadecanoic acid, respectively.The aromatics and their derivatives such as benzene, methylbenzene, and phenol, fatty acids such as a ISOCETYL PALMITATE (İzosetil Palmitat), nitrogen-containing compounds such as amines and amides, and other group alcohols, aldehydes, and ketones were oxygen-containing compounds.DL in ethanol-water cosolvent (EWCS) were more dispersive, and their relative content were lower than 10%, except for ISOCETYL PALMITATE (İzosetil Palmitat) ethyl ester with its relative content of 15.06%. Typically, the content of ISOCETYL PALMITATE (İzosetil Palmitat) produced in HTL reached 17.27% but decreased to 9.79% in EWCS and 3.21% in pure ethanol, while the ISOCETYL PALMITATE (İzosetil Palmitat) ethyl ester content increased from 0% in HTL to 15.06% in EWCS, and then up to 38.4% in pure ethanol. Furthermore, the other ethyl esters such as 5,8,11,14-eicosatetraenoic acid, ethyl ester, (all-Z)- and ethyl linoleate were also higher in bio-oil from EWCS and pure ethanol. This indicated that the addition of ethanol into liquefaction system could serve as a substrate, reacting with acidic components like ISOCETYL PALMITATE (İzosetil Palmitat) and obtaining corresponding esters like ISOCETYL PALMITATE (İzosetil Palmitat) ethyl ester, which is known as etherification. Biswas et al. observed from GS-MS of Sargassum tenerrimum algae-derived bio-oil using water as a solvent for HTL at 280°C (STW280) were 3-pyridiol, p-hydroxybiphenyl, ISOCETYL PALMITATE (İzosetil Palmitat), bis(2-ethylhexyl) phthalate, stigmastan-3,5-diene, and hexadecanamide. For C2H5OH as the solvent (ST-E280) the main compounds were ISOCETYL PALMITATE (İzosetil Palmitat)-ethyl ester, ethyl oleate, tetradecanoic acid-ethyl ester, and isosorbide. Hexadecanoic acid-methyl ester, methyl tetradecanoate, 8-octadecenoic acid methyl ester, and methyl hexadec-9-enoate were the compounds found in major concentrations in bio-oil obtained.This compound, composed of cyclic phosphate and cyclopropane-containing ISOCETYL PALMITATE (İzosetil Palmitat), inhibited more than 80% of the affinity-purified calf thymus DNA polymerase α activity at a concentration of 10 μg/mL.Preparation of one diastereomer of cyclopropane-containing ISOCETYL PALMITATE (İzosetil Palmitat) (81) was summarized in Scheme 7, starting with enzymatic hydrolysis of meso diester (74).Palmitic Acid Palmitic acid (also known as ISOCETYL PALMITATE (İzosetil Palmitat)) is a fatty acid that is found naturally in animals and plants and also can be created in laboratory settings. Palmitic acid is widely used in a variety of applications, including personal care products and cosmetics.Palmitic acid (ISOCETYL PALMITATE (İzosetil Palmitat)) has been for long time negatively depicted for its putative detrimental health effects, shadowing its multiple crucial physiological activities. ISOCETYL PALMITATE (İzosetil Palmitat) is the most common saturated fatty acid accounting for 20–30% of total fatty acids in the human body and can be provided in the diet or synthesized endogenously via de novo lipogenesis (DNL). ISOCETYL PALMITATE (İzosetil Palmitat) tissue content seems to be controlled around a well-defined concentration, and changes in its intake do not influence significantly its tissue concentration because the exogenous source is counterbalanced by ISOCETYL PALMITATE (İzosetil Palmitat) endogenous biosynthesis. Particular physiopathological conditions and nutritional factors may strongly induce DNL, resulting in increased tissue content of ISOCETYL PALMITATE (İzosetil Palmitat) and disrupted homeostatic control of its tissue concentration. The tight homeostatic control of ISOCETYL PALMITATE (İzosetil Palmitat) tissue concentration is likely related to its fundamental physiological role to guarantee membrane physical properties but also to consent protein palmitoylation, palmitoylethanolamide (PEA) biosynthesis, and in the lung an efficient surfactant activity. In order to maintain membrane phospholipids (PL) balance may be crucial an optimal intake of ISOCETYL PALMITATE (İzosetil Palmitat) in a certain ratio with unsaturated fatty acids, especially PUFAs of both n-6 and n-3 families. However, in presence of other factors such as positive energy balance, excessive intake of carbohydrates (in particular mono and disaccharides), and a sedentary lifestyle, the mechanisms to maintain a steady state of ISOCETYL PALMITATE (İzosetil Palmitat) concentration may be disrupted leading to an over accumulation of tissue ISOCETYL PALMITATE (İzosetil Palmitat) resulting in dyslipidemia, hyperglycemia, increased ectopic fat accumulation and increased inflammatory tone via toll-like receptor 4. It is therefore likely that the controversial data on the association of dietary ISOCETYL PALMITATE (İzosetil Palmitat) with detrimental health effects, may be related to an excessive imbalance of dietary ISOCETYL PALMITATE (İzosetil Palmitat)/PUFA ratio which, in certain physiopathological conditions, and in presence of an enhanced DNL, may further accelerate these deleterious effects.Palmitic acid (16:0, ISOCETYL PALMITATE (İzosetil Palmitat)) is the most common saturated fatty acid found in the human body and can be provided in the diet or synthesized endogenously from other fatty acids, carbohydrates and amino acids.n average, a 70-kg man is made up of 3.5 Kg of ISOCETYL PALMITATE (İzosetil Palmitat). As the name suggests, ISOCETYL PALMITATE (İzosetil Palmitat) is a major component of palm oil (44% of total fats), but significant amounts of ISOCETYL PALMITATE (İzosetil Palmitat) can also be found in meat and dairy products (50–60% of total fats), as well as cocoa butter (26%) and olive oil (8–20%). Furthermore, ISOCETYL PALMITATE (İzosetil Palmitat) is present in breast milk with 20–30% of total fats.The tight homeostatic control of ISOCETYL PALMITATE (İzosetil Palmitat) tissue concentration is likely related to its fundamental physiological role in several biological functions. Particularly in infants ISOCETYL PALMITATE (İzosetil Palmitat) seems to play a crucial role as recently thoroughly revised by Innis (Innis, 2016). The disruption of ISOCETYL PALMITATE (İzosetil Palmitat) homeostatic balance, implicated in different physiopathological conditions such as atherosclerosis, neurodegenerative diseases and cancer, is often related to an uncontrolled ISOCETYL PALMITATE (İzosetil Palmitat) endogenous biosynthesis, irrespective of its dietary contribution.FA synthesis starts with citrate conversion to acetyl-CoA and then malonyl-CoA, which is then elongated to form palmitate and other FA. Key enzymes in this process are acetyl-CoA carboxylase (ACC), which catalyzes the DNL limiting step reaction, and the FA synthase (FAS). The main sources of citrate for DNL are glucose and glutamine-derived α-ketoglutarate (α-KG), especially under hypoxia or disruption of the mitochondrial oxidative machinery.Palmitic acid, or ISOCETYL PALMITATE (İzosetil Palmitat), is one of the most common saturated fatty acids found in animals, plants, and microorganisms.Palmitic acid is used to produce soaps, cosmetics, and industrial mould release agents.Palmitic acid is also used in the determination of water hardness and is a surfactant of Levovist, an intravenous ultrasonic contrast agent.Palmitic acid, or ISOCETYL PALMITATE (İzosetil Palmitat) in IUPAC nomenclature, is the most common saturated fatty acid found in animals, plants and microorganisms.[9][10] Its chemical formula is CH3(CH2)14COOH, and its C:D is 16:0.

Safety Measures/Side Effects: The Cosmetic Ingredient Review (CIR) Expert Panel has assessed this ingredient as non-toxic and non-irritating, thus determining it as safe to use in cosmetic products. It has been shown to be comedogenic (clog the pores), and should be avoided by those with oily and acne prone skin types.Decyl Oleate and lsodecyl Oleate are esters of oleic acid. Decyl Oleate is used in cosmetic products at concentrations ranging from I 0.1 to > 50%. Isodecyl Oleate is used at concentrations of > 0.1-25%. Animal studies have shown both Decyl Oleate and lsodecyl Oleate to possess low acute oral toxicities in rats with LD50s of > 40 ml/kg, Single application dermal and eye studies with rabbits have shown these materials at 100% concentrations produce little or no irritation. Daily applications of 159b or 100% concentrations for 60 days to the skin of rabbits produced a moderate degree of irritation with both Decyl and lsodecyl Oleate. Neither of the ingredients was found to be a sensitizer when tested in guinea pigs at concentrations of 15%. Repeated insult patch tests containing 1-5'1'0 Decyl Oleate showed no signs of sensitization. Testing with formulations containing 5.5% Decyl Oleate produced a low number of reactions in 402 human subjects in the SchwartzPeck Prophetic Patch Test and 204 subjects with undiluted lsodecyl Oleate on nine subjects showed a total irritation score of 1 .O out of a maximum of 756. It is concluded that, because of both the chemical similarity of these compounds and the similarity of the available animal and human data, Decyl and lsodecyl Oleates warrant a conclusion of safe in the concentrations of present practices and use in cosmetics. ecyl Oleate and lsodecyl Oleate are esters of oleic acid. Formed by ester- D ification of oleic acid with decyl or isodecyl alcohol, they have the following structural formulas: Decyl Oleate- lsodecyl Oleate- CH3 (CH CH=CH(CH2) 7COOCH2 (CH2) 6CH (CH3) 27 Methyl Oleate is a compound chemically related to Decyl Oleate and lsodecyl Oleate.

Information and data pertaining to this compound are included to permit a more complete appraisal of the safety of Decyl Oleate and lsodecyl Oleate.Some of the chemical and physical properties of these esters are given in Reactivity Unsaturated fatty acids and their esters readily undergo aut~xidation.'~) Methyl oleate can serve as a model for autoxidation reactions which all the oleic acid esters exhibited. This compound undergoes autoxidation to give primarily trans-hydro peroxide^,'^) which are highly unstable and readily decompose to keto and hydroxy keto acids.(6) Some hydroperoxides have been found to possess carcinogenic potential.") Methyl oleate undergoes photochemical decomposition in direct sunlight and in the presence of oxygen to form the ozonide of methyl oleic acid.(*) The most important secondary products of autoxidation include alpha, beta-u nsatu rated carbonyl com pou nds.(5) Hemati n com pou nds, (') metals, (lo) and chlorinated hydrocarbon i nsecticides' ") accelerate the autoxidation reaction by shortening the induction period. Analytical Methods Methyl oleate can be generated in purities of 98% or better by repeated distillation with urea at a low temperature.('2) Analysis of this and related compounds is done by gas-liquid or thin-layer chromatography. The position of the double bond can be determined by von Rudolph's oxidation procedure. Infrared spectroscopy can be used to delineate cis-trans i~omers.('~-~~) Although gas-liquid chromatography remains the preferred routine analytical method for fatty acid ester mixtures, utilization of high performance liquid chromatography (HPLC) is increasing; for the latter has the advantage of identifying polymerized and oxidized esters which the former does not dete. PURPOSE AND FREQUENCY OF USE IN COSMETICS Decyl and lsodecyl Oleates have been widely used in cosmetic products. When applied to the skin alone, they deposit a thin oily film that is neither greasy nor tacky. They have good lubrication properties and possess low viscosity.(") Both materials are used as dispersants and lubricants in cosmetic formulations, and these are particularly important in makeup and makeup removers, in which they are used as wetting agents for iron oxide pigments; particles of such pigment are dispersed and easily suspended. The use of these ingredients facilities the application and removal of a suspension. By virtue of its branched chain structure, lsodecyl Oleate possesses several distinct properties. It has the ability to lower the freezing point of the emulsion phase of products, as well as to control product viscosity. In dispersible bath oils, it forms a white emulsion, giving the tub water a rich and milky appearance. It also has the ability to suspend aluminum chlorohydrate, which makes it valuable for dry antiperspirant formulations. Lipstick formulations have employed lsodecyl Oleate because its coupling properties increase the hardness and strength of the product without reducing its flow characteristics. Table 2 indicates categories of product use and concentrations of use for Decyl and lsodecyl Oleate.('*) The cosmetic product formulation computer printout which is made available by the Food and Drug Administration (FDA) is compiled through voluntary filing of such data in accordance with Title 21 Part 720.4 of the Code of Federal Regulations (1979). Ingredients are listed in prescribed concentration ranges under specific product type categories. Since certain cosmetic ingredients are supplied by the manufacturer at less that 100% concentration, the value reported by the cosmetic formulator may not necessarily reflect the true, effective concentration found in the finished product; the effective concentration in such a case would be a fraction of that reported to the FDA. The fact that data are only submitted within the framework of preset concentration ranges also provides the opportunity for overestimation of the actual concentration of an ingredient in a particular product. An entry at the lowest end of a concentration range is considered the same as one entered at the highest end of that range, thus introducing the possibility of a two- to ten-fold error in the assumed ingredient concentration. The compounds are employed in a variety of cosmetics, including makeup preparations, skin care preparations, and eye-shadow. Concentrations of use range from 50.1 to > for Decyl Oleate and > 0.1-25% for I sod ec y I 0 leate. Products containing these two materials are applied with varying frequency to all areas of the skin. In such formulations as blushers and moisturizing creams, exposure may occur several times a day, while in other cases there may be daily (deodorants) or less frequent (rinses, hair conditioners) applications. This occasional or daily use may extend over a period of years. Animal Toxicology Decyl Oleate: This ingredient was administered to Wistar rats by intragastric intubation at dose levels of 2.5, 5.0, 10.0, 20.0, and 40.0 mllkg COSMETIC INGREDIENT REVIEW two female rats per dose The animals were fasted for 24 hours prior to dosing. All animals were observed daily for 14 days following administration and no deaths were recorded. The acute LD50 of undiluted Decyl Oleate was greater than 40.0 mllkg of body weight. Wistar-derived rats (groups of five male, five female) were dosed by gavage with either 5.0 glkg of undiluted Decyl Oleate or 5.0 glkg of 20 percent Decyl Oleate, 80% mineral The rats were fasted for 18 hours prior to dosing. The animals were observed for signs of pharmacologic activity and drug toxicity at 1, 3, 6, and 24 hours post-dosing, after which daily observations were made for a total of 14 days. One death was recorded for male animals in the diluted sample group, and one female died following treatment with the undiluted sample. No treatment-related effects were noted in any of the surviving animals. Examination of tissues of nons,urvivors and survivors at gross autopsy revealed no abnormalities. lsodecyl Oleate: This ingredient was administered to Wistar rats by intragastric intubation at dose levels of 2.5, 5.0, 10.0, 20.0, and 40.0 mllkg (two female and three male rats per dose The animals were fasted for 24 hours prior to dosing. One death was recorded at the highest dose level. The acute LD50 of undiluted Isodecyl Oleate was reported to be greater than 40.0 ml/kg of body weight. Dermal irritation Decyl Oleate: Drai~e'~~) and Federal Hazardous Substances Labeling Act(22) (FHSA) methods were used to conduct primary skin irritation studies. Test samples of Decyl Oleate (undiluted, 10 percent in corn oil and 20% in mineral oil) were applied (0.5 ml) to clipped areas of intact and abraded albino rabbits skin (six animals in each group). The abrasions were longitudinal, epidermal incisions sufficiently deep to penetrate the stratum corneum, but not so deep as to disturb the dermis. Following application of the test material, the exposed area was covered with a patch and the entire experimental area was sealed with impervious sheeting. The animals were immobilized for a 24-hour period. The mean scores for 24- and 72-hour gradings were averaged to determine final irritation values. The primary irritation index (PII) for undiluted Decyl Oleate was calculated to be 0.28.L25) Itwas also determined that Decyl Oleate had primary irritation indices of 0.08 as a 10 percent solution in corn oil(22) and 0.05 as a 20% solution in mineral A modified Draize method was used to conduct primary dermal irritation studies with undiluted and 15% Decyl Oleate diluted in polyoxyethylene sorbitan stearate (3%), a perservative (2%)) and water; the material was found to be nonirritating (Table 3).("j) ISODECYL OLEATE ISODECYL OLEATE is classified as : Emollient Skin conditioning CAS Number 59231-34-4 EINECS/ELINCS No: 261-673-6 COSING REF No: 34643 Chem/IUPAC Name: Isodecyl oleate Isodecyl Oleate Definition Isodecyl Oleate is a moisturizer that can also be found in cosmetics. As a moisturizer in our products, decyl oleate helps prevent a product or surface, like leather, from drying out by helping it retain moisture. This makes it softer and more pliable. Clinical Assessment of Safety Decyl Oleate: A human repeated insult patch test was conducted on 103 subjects with a skin conditioner containing 1-5% Decyl Oleate. Patches containing approximately 0.2 ml of undiluted sample were applied on Monday, Wednesday, and Friday for three consecutive weeks. Fourteen days after the final insult patch, challenge patches containing the undiluted skin conditioner were applied, and results were graded 48 and 96 hours later. No evidence of sensitization was found; no information on irritation potential was Four formulations of a foundation containing Decyl Oleate (5.5%) were tested in the Schwartz-Peck Prophetic Patch Test and the Draize-Shelanski Repeated Insult Patch Test. "Virtually zero reactions occurred in 402 subjects in the Schwartz-Peck Test and 204 subjects in the Draize-Shelanski Test."(23) lsodecyl Oleate: A single insult (24-hour) occlusive patch test was conducted on 19 human subjects with undiluted lsodecyl Oleate. The test material did not elicit any erythematous reactions. A summary report of the study concluded that Isodecyl Oleate exhibits an acceptably low incidence of primary skin irritation under occlusive patch test According to an industry raw material evaluation, a procedure was undertaken with lsodecyl Oleate under the conditions of a Maibach-type Cumulative lrritancy Assay. When lsodecyl Oleate was applied undiluted under patch conditions to the skin of nine subjects for 21 consecutive days, it was found to have a total irritation score of 1 .O out of a maximum possible 756.(30) SUMMARY Decyl Oleate and lsodecyl Oleate are esters of oleic acid. Decyl Oleate is used in cosmetic products at concentrations ranging from 10.1 to >50°/o. lsodecyl Oleate is used at concentrations of > 0.1 -25%. Animal studies have shown Decyl Oleate and lsodecyl Oleate to possess low acute oral toxicities in rats; both have LD50s of > 40 mllkg. Single application dermal and eye studies with rabbits have shown that these materials in concentrations up to 100% produce little or no irritation. When 15% or 100°/o concentrations were applied to the skin of rabbits daily for 60 days, both Decyl Oleate and lsodecyl Oleate produced moderate degrees of irritation. Neither ingredient was found to be a sensitizer when it was tested in guinea pigs at concentrations of 15%. Repeated human insult patch tests on 103 subjects with a skin conditioner containing 1-5% Decyl Oleate showed no signs of sensitization. Industrial testing with formulations containing 5.5% Decyl Oleate produced a low number of reactions in 402 human subjects in the Schwartz-Peck Prophetic Patch Test and in 204 subjects in the Draize-Shelanski Patch Test. Repeated insult patch tests with undiluted Isodecyl Oleate on an unspecified number of human subjects showed a total irritation score of 1 .O out of a possible maximum of 756. A single insult occlusive patch test on 19 human subjects with undiluted lsodecyl Oleate produced a low level of primary skin irritation. No chronic, oral subchronic, carcinogenicity, mutagenicity, or teratogenicity animal testing data were available to the Panel. Nor were there any phototoxicity or photosensitization studies in humans.

ISOPROPANOL
ISOPROPANOL Isopropyl Alcohol Isopropanol (izopropil alkol, Isopropanol, IPA) is an organic compound, an isomer of n-propanol, aliased dimethylmethanol, 2-propanol. Isopropanol (izopropil alkol, Isopropanol, IPA) is a colorless, transparent liquid with a scent like a mixture of ethanol and acetone. Soluble in water, also soluble in most organic solvents such as alcohol, ether, benzene, chloroform, etc. Isopropanol (izopropil alkol, Isopropanol, IPA) has a wide range of uses as an organic raw material and solvent. 1)As a chemical raw material, it can produce acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, diisopropyl ether, isopropyl chloride, and fatty acid isopropyl ester and chloro fatty acid isopropyl ester. 2)In the fine chemical industry, it can be used to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum isopropoxide, pharmaceuticals and pesticides, etc. It can also be used to produce diisopropanone, isopropyl acetate and Thymol and gasoline additives. 3)Isopropanol (izopropil alkol, Isopropanol, IPA) Can be used to produce coatings, inks, extractants, aerosols, etc. 4) In the electronics industry, Isopropanol (izopropil alkol, Isopropanol, IPA) can be used as a cleaning and degreasing agent. 5) In the oil and fat industry, the extractant of cottonseed oil can also be used for degreasing of animal-derived tissue membranes. Isopropanol (izopropil alkol, Isopropanol, IPA) (IUPAC name propan-2-ol; commonly called isopropanol or 2-propanol) is a colorless, flammable chemical compound (chemical formula CH3CHOHCH3) with a strong odor.[8] As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of 1-propanol and ethyl methyl ether. Isopropanol (izopropil alkol, Isopropanol, IPA) is used in the manufacture of a wide variety of industrial and household chemicals and is a common ingredient in chemicals such as antiseptics, disinfectants, and detergents. Names of Isopropanol (izopropil alkol, Isopropanol, IPA) Isopropanol (izopropil alkol, Isopropanol, IPA) Isopropanol (izopropil alkol, Isopropanol, IPA) is also known as 2-propanol, sec-propyl alcohol, IPA, or isopropanol. IUPAC considers isopropanol an incorrect name as the hydrocarbon isopropane does not exist. Properties of Isopropanol (izopropil alkol, Isopropanol, IPA) Isopropanol (izopropil alkol, Isopropanol, IPA) is miscible in water, ethanol, ether, and chloroform. It dissolves ethyl cellulose, polyvinyl butyral, many oils, alkaloids, gums and natural resins.[9] Unlike ethanol or methanol, Isopropanol (izopropil alkol, Isopropanol, IPA) is not miscible with salt solutions and can be separated from aqueous solutions by adding a salt such as sodium chloride. The process is colloquially called salting out, and causes concentrated Isopropanol (izopropil alkol, Isopropanol, IPA) to separate into a distinct layer. Isopropanol (izopropil alkol, Isopropanol, IPA) forms an azeotrope with water, which gives a boiling point of 80.37 °C (176.67 °F) and a composition of 87.7 wt% (91 vol%) Isopropanol (izopropil alkol, Isopropanol, IPA). Water-Isopropanol (izopropil alkol, Isopropanol, IPA) mixtures have depressed melting points.[10] It has a slightly bitter taste, and is not safe to drink. Isopropanol (izopropil alkol, Isopropanol, IPA) becomes increasingly viscous with decreasing temperature and freezes at -89 °C (-128 °F). Isopropanol (izopropil alkol, Isopropanol, IPA) has a maximal absorbance at 205 nm in an ultraviolet-visible spectrum. Reactions of Isopropanol (izopropil alkol, Isopropanol, IPA) Isopropanol (izopropil alkol, Isopropanol, IPA) can be oxidized to acetone, which is the corresponding ketone. This can be achieved using oxidizing agents such as chromic acid, or by dehydrogenation of Isopropanol (izopropil alkol, Isopropanol, IPA) over a heated copper catalyst: (CH3)2CHOH → (CH3)2CO + H2 Isopropanol (izopropil alkol, Isopropanol, IPA) is often used as both solvent and hydride source in the Meerwein-Ponndorf-Verley reduction and other transfer hydrogenation reactions. Isopropanol (izopropil alkol, Isopropanol, IPA) may be converted to 2-bromopropane using phosphorus tribromide, or dehydrated to propene by heating with sulfuric acid. Like most alcohols, Isopropanol (izopropil alkol, Isopropanol, IPA) reacts with active metals such as potassium to form alkoxides that can be called isopropoxides. The reaction with aluminium (initiated by a trace of mercury) is used to prepare the catalyst aluminium isopropoxide.[14] History of Isopropanol (izopropil alkol, Isopropanol, IPA) In 1920, Standard Oil first produced Isopropanol (izopropil alkol, Isopropanol, IPA) by hydrating propene. Its major use at the time was not rubbing alcohol but for oxidation to acetone, whose first major use was in World War I for the preparation of cordite, a smokeless, low explosive propellant. Production of Isopropanol (izopropil alkol, Isopropanol, IPA) In 1994, 1.5 million tonnes of Isopropanol (izopropil alkol, Isopropanol, IPA) were produced in the United States, Europe, and Japan.[16] It is primarily produced by combining water and propene in a hydration reaction or by hydrogenating acetone. There are two routes for the hydration process and both processes require that the Isopropanol (izopropil alkol, Isopropanol, IPA) be separated from water and other by-products by distillation. Isopropanol (izopropil alkol, Isopropanol, IPA) and water form an azeotrope, and simple distillation gives a material that is 87.9% by weight Isopropanol (izopropil alkol, Isopropanol, IPA) and 12.1% by weight water.[18] Pure (anhydrous) Isopropanol (izopropil alkol, Isopropanol, IPA) is made by azeotropic distillation of the wet Isopropanol (izopropil alkol, Isopropanol, IPA) using either diisopropyl ether or cyclohexane as azeotroping agents.[16] Biological of Isopropanol (izopropil alkol, Isopropanol, IPA) Small amounts of Isopropanol (izopropil alkol, Isopropanol, IPA) are produced in the body in diabetic ketoacidosis.[19] Indirect hydration of Isopropanol (izopropil alkol, Isopropanol, IPA) Indirect hydration reacts propene with sulfuric acid to form a mixture of sulfate esters. This process can use low-quality propene, and is predominant in the USA. These processes give primarily Isopropanol (izopropil alkol, Isopropanol, IPA) rather than 1-propanol, because adding water or sulfuric acid to propene follows Markovnikov's rule. Subsequent hydrolysis of these esters by steam produces Isopropanol (izopropil alkol, Isopropanol, IPA), by distillation. Diisopropyl ether is a significant by-product of this process; it is recycled back to the process and hydrolyzed to give the desired product. CH3CH=CH2 + H2O H2SO4⟶ (CH3)2CHOH Direct hydration of Isopropanol (izopropil alkol, Isopropanol, IPA) See also: Heteropoly acid Direct hydration reacts propene and water, either in gas or liquid phase, at high pressures in the presence of solid or supported acidic catalysts. This type of process usually requires higher-purity propylene (> 90%).[16] Direct hydration is more commonly used in Europe. Hydrogenation of acetone Isopropanol (izopropil alkol, Isopropanol, IPA) may be prepared via the hydrogenation of acetone, however this approach involves an extra step compared to the above methods, as acetone is itself normally prepared from propene via the cumene process.[16] It may remain economical depending on the value of the products. A known issue is the formation of MIBK and other self-condensation products. Raney nickel was one of the original industrial catalysts, modern catalysts are often supported bimetallic materials. This is an efficient process and easy Uses of Isopropanol (izopropil alkol, Isopropanol, IPA) One of the small scale uses of isopropanol is in cloud chambers. Isopropanol has ideal physical and chemical properties to form a supersaturated layer of vapor which can be condensed by particles of radiation. In 1990, 45,000 metric tonnes of Isopropanol (izopropil alkol, Isopropanol, IPA) were used in the United States, mostly as a solvent for coatings or for industrial processes. In that year, 5400 metric tonnes were used for household purposes and in personal care products. Isopropanol (izopropil alkol, Isopropanol, IPA) is popular in particular for pharmaceutical applications,[16] due to its low toxicity. Some Isopropanol (izopropil alkol, Isopropanol, IPA) is used as a chemical intermediate. Isopropanol (izopropil alkol, Isopropanol, IPA) may be converted to acetone, but the cumene process is more significant. [16] Solvent of Isopropanol (izopropil alkol, Isopropanol, IPA) Isopropanol (izopropil alkol, Isopropanol, IPA) dissolves a wide range of non-polar compounds. It also evaporates quickly, leaves nearly zero oil traces, compared to ethanol, and is relatively non-toxic, compared to alternative solvents. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils. Together with ethanol, n-butanol, and methanol, it belongs to the group of alcohol solvents, about 6.4 million tonnes of which were used worldwide in 2011.[20] Isopropanol (izopropil alkol, Isopropanol, IPA) is commonly used for cleaning eyeglasses, electrical contacts, audio or video tape heads, DVD and other optical disc lenses, removing thermal paste from heatsinks on CPUs and other IC packages, etc. Intermediate Isopropanol (izopropil alkol, Isopropanol, IPA) is esterified to give isopropyl acetate, another solvent. It reacts with carbon disulfide and sodium hydroxide to give sodium isopropylxanthate, a herbicide and an ore flotation reagent.[21] Isopropanol (izopropil alkol, Isopropanol, IPA) reacts with titanium tetrachloride and aluminium metal to give titanium and aluminium isopropoxides, respectively, the former a catalyst, and the latter a chemical reagent.[16] This compound may serve as a chemical reagent in itself, by acting as a dihydrogen donor in transfer hydrogenation. Medical of Isopropanol (izopropil alkol, Isopropanol, IPA) Rubbing alcohol, hand sanitizer, and disinfecting pads typically contain a 60-70% solution of Isopropanol (izopropil alkol, Isopropanol, IPA) or ethanol in water. Water is required to open up membrane pores of bacteria, which acts as a gateway for Isopropanol (izopropil alkol, Isopropanol, IPA). A 75% v/v solution in water may be used as a hand sanitizer.[22] Isopropanol (izopropil alkol, Isopropanol, IPA) is used as a water-drying aid for the prevention of otitis externa, better known as swimmer's ear.[23] Early uses as an anesthetic Although Isopropanol (izopropil alkol, Isopropanol, IPA) can be used for anesthesia, its many negative attributes or drawbacks prohibit this use. Isopropanol (izopropil alkol, Isopropanol, IPA) can also be used similarly to ether as a solvent[24] or as an anesthetic by inhaling the fumes or orally. Early uses included using the solvent as general anesthetic for small mammals[25] and rodents by scientists and some veterinarians. However, it was soon discontinued, as many complications arose, including respiratory irritation, internal bleeding, and visual and hearing problems. In rare cases, respiratory failure leading to death in animals was observed. Automotive Isopropanol (izopropil alkol, Isopropanol, IPA) is a major ingredient in "gas dryer" fuel additives. In significant quantities, water is a problem in fuel tanks, as it separates from gasoline and can freeze in the supply lines at low temperatures. Alcohol does not remove water from gasoline, but the alcohol solubilizes water in gasoline. Once soluble, water does not pose the same risk as insoluble water, as it no longer accumulates in the supply lines and freezes but is consumed with the fuel itself. Isopropanol (izopropil alkol, Isopropanol, IPA) is often sold in aerosol cans as a windshield or door lock deicer. Isopropanol (izopropil alkol, Isopropanol, IPA) is also used to remove brake fluid traces from hydraulic braking systems, so that the brake fluid (usually DOT 3, DOT 4, or mineral oil) does not contaminate the brake pads and cause poor braking. Mixtures of Isopropanol (izopropil alkol, Isopropanol, IPA) and water are also commonly used in homemade windshield washer fluid. Laboratory As a biological specimen preservative, Isopropanol (izopropil alkol, Isopropanol, IPA) provides a comparatively non-toxic alternative to formaldehyde and other synthetic preservatives. Isopropanol (izopropil alkol, Isopropanol, IPA) solutions of 70-99% are used to preserve specimens. Isopropanol (izopropil alkol, Isopropanol, IPA) is often used in DNA extraction. A lab worker adds it to a DNA solution to precipitate the DNA, which then forms a pellet after centrifugation. This is possible because DNA is insoluble in Isopropanol (izopropil alkol, Isopropanol, IPA). Safety of Isopropanol (izopropil alkol, Isopropanol, IPA) Isopropanol (izopropil alkol, Isopropanol, IPA) vapor is denser than air and is flammable, with a flammability range of between 2 and 12.7% in air. It should be kept away from heat and open flame.[26] Distillation of Isopropanol (izopropil alkol, Isopropanol, IPA) over magnesium has been reported to form peroxides, which may explode upon concentration. Isopropanol (izopropil alkol, Isopropanol, IPA) is a skin irritant. Wearing protective gloves is recommended. Toxicology of Isopropanol (izopropil alkol, Isopropanol, IPA) Isopropanol (izopropil alkol, Isopropanol, IPA) and its metabolite, acetone, act as central nervous system (CNS) depressants.[31] Poisoning can occur from ingestion, inhalation, or skin absorption. Symptoms of Isopropanol (izopropil alkol, Isopropanol, IPA) poisoning include flushing, headache, dizziness, CNS depression, nausea, vomiting, anesthesia, hypothermia, low blood pressure, shock, respiratory depression, and coma.[31] Overdoses may cause a fruity odor on the breath as a result of its metabolism to acetone.[32] Isopropanol (izopropil alkol, Isopropanol, IPA) does not cause an anion gap acidosis but it produces an osmolal gap between the calculated and measured osmolalities of serum, as do the other alcohols.[31] Isopropanol (izopropil alkol, Isopropanol, IPA) is oxidized to form acetone by alcohol dehydrogenase in the liver,[31] and has a biological half-life in humans between 2.5 and 8.0 hours.[31] Unlike methanol or ethylene glycol poisoning, the metabolites of Isopropanol (izopropil alkol, Isopropanol, IPA) are considerably less toxic, and treatment is largely supportive. Furthermore, there is no indication for the use of fomepizole, an alcohol dehydrogenase inhibitor, unless co-ingestion with methanol or ethylene glycol is suspected. In forensic pathology, people who have died as a result of diabetic ketoacidosis usually have blood concentrations of Isopropanol (izopropil alkol, Isopropanol, IPA) of tens of mg/dL, while those by fatal Isopropanol (izopropil alkol, Isopropanol, IPA) ingestion usually have blood concentrations of hundreds of mg/dL. Isopropanol (izopropil alkol, Isopropanol, IPA) will attack some forms of plastics, rubber, and coatings. Isopropanol (izopropil alkol, Isopropanol, IPA) is an isomer of propyl alcohol with antibacterial properties. Although the exact mechanism of isopropanol's disinfecting action is not known, it might kill cells by denaturing cell proteins and DNA, interfering with cellular metabolism, and dissolving cell lipo-protein membranes. Isopropanol is used in soaps and lotions as an antiseptic. Any clothing which becomes wet with liquid Isopropanol (izopropil alkol, Isopropanol, IPA) should be removed immediately and not reworn until the Isopropanol (izopropil alkol, Isopropanol, IPA) is removed from the clothing. Clothing should then be placed in closed containers for storage until it can be discarded or until provision can be made for the removal of Isopropanol (izopropil alkol, Isopropanol, IPA) from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the Isopropanol (izopropil alkol, Isopropanol, IPA), the person performing the operation should be informed of Isopropanol (izopropil alkol, Isopropanol, IPA)'s hazardous properties. When a stream of hydrogen entrained Isopropanol (izopropil alkol, Isopropanol, IPA) vapors and palladium particles, the mixture caught fire on exposure to air. Solutions of 90% nitroform in 10% Isopropanol (izopropil alkol, Isopropanol, IPA) in polyethylene bottles exploded. The reaction between Isopropanol (izopropil alkol, Isopropanol, IPA) and phosgene forms isopropyl chloroformate and hydrogen chloride. In the presence of iron salts thermal decomposition can occur, which in some cases can become explosive. Mixing oleum and Isopropanol (izopropil alkol, Isopropanol, IPA) in a closed container caused the temperature and pressure to increase. Isopropanol (izopropil alkol, Isopropanol, IPA) (without residue) may be used in inks for marking food supplements in tablet form, gum, and confectionery. Isopropanol (izopropil alkol, Isopropanol, IPA) may be present in the following foods under the conditions specified: (a) In spice oleoresins as a residue from the extraction of spice, at a level not to exceed 50 parts per million. (b) In lemon oil as a residue in production of the oil, at a level not to exceed 6 parts per million. (c) In hops extract as a residue from the extraction of hops at a level not to exceed 2.0 percent by weight: Provided, that, (1) The hops extract is added to the wort before or during cooking in the manufacture of beer. (2) The label of the hops extract specifies the presence of the Isopropanol (izopropil alkol, Isopropanol, IPA) and provides for the use of the hops extract only as prescribed by paragraph (c)(1) of this section. WORKERS IN AN Isopropanol (izopropil alkol, Isopropanol, IPA) PACKAGING PLANT BECAME ILL AFTER ACCIDENTAL EXPOSURE TO CARBON TETRACHLORIDE. Isopropanol (izopropil alkol, Isopropanol, IPA) POTENTIATION OF CARBON TETRACHLORIDE TOXICITY HAS BEEN SHOWN PREVIOUSLY ONLY IN RATS. ACETONE, A PRODUCT OF Isopropanol (izopropil alkol, Isopropanol, IPA) METABOLISM, IS A MAJOR POTENTIATOR OF CARBON TETRACHLORIDE TOXICITY. IDENTIFICATION: Isopropanol (izopropil alkol, Isopropanol, IPA) is an aliphatic alcohol hydrocarbon. It is prepared from propylene, which is obtained in the cracking of petroleum or by the reduction of acetone. It is a colorless liquid which is soluble in water, alcohol, ether, acetone, benzene and chloroform. It is insoluble in salt solutions. It has a slight odor resembling a mixture of ethanol and acetone and has a slight bitter taste. It is used in antifreeze, industrial solvent, solvent for gums, shellac, essential oils, in quick drying oils, creosote and resins; extraction of alkaloids; in quick drying inks; in denaturing ethyl alcohol; in body rubs, hand lotions, after shave lotions, cosmetics and pharmaceuticals; in manufacture of acetone, glycerol, isopropyl acetate; antiseptic; rubefacient ; and pharmaceutical aid. HUMAN EXPOSURE: Toxic effects include central nervous depression, liver, kidney, cardiovascular depression and brain damage. It can cause drowsiness, ataxia, stupor, coma and respiratory depression, irritation of mucous membranes and eyes, gastritis, gastric hemorrhage, vomiting, pancreatitis, cold clammy skin, hypothermia, miosis, tachycardia, slow and noisy respiration. High risk of circumstances of poisoning: Accidental ingestion of rubbing alcohols/toiletries by children. There is a potential exposure from dermal and inhalation exposure in children during Isopropanol (izopropil alkol, Isopropanol, IPA) sponging for control of fever. Intentional ingestion for alcoholic effect or in suicide attempts. Occupational or accidental exposure to liquid or its vapor in industrial applications. Individuals exposed to Isopropanol (izopropil alkol, Isopropanol, IPA) include the following: workers in the pharmaceutical industry, cosmetic industry, chemical industry, petroleum workers, laboratory workers, printers, painters and carpenters and cabinet makers. There is little absorption through intact skin. Isopropanol (izopropil alkol, Isopropanol, IPA) is a potent eye and skin irritant. 80% of an oral dose is absorbed within 30 minutes. Absorption is complete within 2 hours although this may be delayed in a large overdose. Alveolar concentration is correlated to the environmental concentration at any given time. Isopropanol (izopropil alkol, Isopropanol, IPA) is absorbed through intact skin on prolonged exposure. Isopropanol (izopropil alkol, Isopropanol, IPA) distributes in body water with an apparent volume of distribution of 0.6-0.7 L/kg. 20-50% of an absorbed dose is excreted unchanged. Most Isopropanol (izopropil alkol, Isopropanol, IPA) is oxidized in the liver by alcohol dehydrogenase to acetone, formate and finally carbon dioxide. Acetone is slowly eliminated by the lung (40%) or kidney. Clinically insignificant excretion occurs into the stomach and saliva. Related keto acids are not produced in sufficient quantities to cause a severe metabolic acidosis. Inebriation, peripheral vasodilation has occurred. In children, hypoglycemia is particularly severe when poisoning following fasting, exercise or chronic malnutrition Lactic acidosis may occur in patients with severe liver disease, pancreatitis or receiving biguanide therapy or as a result of the hypovolemia which frequently accompanies severe intoxication. ANIMAL STUDIES: Isopropanol (izopropil alkol, Isopropanol, IPA) most closely follows first order kinetics, with a half life of 2.5 to 3.2 hours. The elimination half life of the active metabolite acetone is significantly prolonged to about 5 hours in rats. In rat hepatocytes the following has been observed: marked depletion of glutathione, increased malondialdehyde production, decreased protein sulfhydryls content and leakage of lactic dehydrogenase with loss of membrane activity. A complete history and physical examination should be performed to detect pre existing conditions that might place the employee at increased risk, and to establish a baseline for future health monitoring. Examination of the skin, liver, kidneys, and respiratory system should be stressed. Skin disease: Isopropanol (izopropil alkol, Isopropanol, IPA) is a defatting agent and can cause dermatitis on prolonged exposure. Persons with pre existing skin disorders may be more susceptible to the effects of this agent. Liver disease: Although Isopropanol (izopropil alkol, Isopropanol, IPA) is not known as a liver toxin in humans, the importance of this organ in the biotransformation and detoxification of foreign substances should be considered before exposing persons with impaired liver function. Kidney disease: Although Isopropanol (izopropil alkol, Isopropanol, IPA) is not known as a kidney toxin in humans, the importance of this organ in the elimination of toxic substances justifies special consideration in those with impaired renal function. Chronic respiratory disease: In persons with impaired pulmonary function, especially those with obstructive airway diseases, the breathing of Isopropanol (izopropil alkol, Isopropanol, IPA) might cause exacerbation of symptoms due to its irritant properties. Periodic Medical Examination: The aforementioned medical examinations should be repeated on an annual basis. The assessment of Isopropanol (izopropil alkol, Isopropanol, IPA) exposure can be accomplished through measurement of either Isopropanol (izopropil alkol, Isopropanol, IPA) or acetone. Isopropanol (izopropil alkol, Isopropanol, IPA) measurement has not been found to be a good assessment of low level exposure, due to its low sensitivity. However, measurement of acetone has been found to be a good indicator of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) exposure for exposures as low as 70 ppm, and has been found to correlate well with air concentrations. Whole Blood Reference Ranges: Normal - none detected (Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)); Exposed - BAT (sampling time is end of exposure or end of shift, measured as the metabolite, acetone), 50 mg/l; Toxic - Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) level associated with serious toxic symptoms is 150 mg/l. Serum or Plasma Reference Ranges: Normal - none detected (Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)); Exposed - not established; and Toxic - not established. Urine Reference Ranges: The assessment of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) exposure can be accomplished through measurement of either Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) or acetone. However only acetone was found to be a useful test, due to its greater sensitivity and good correlation with air exposure levels. Normal - none detected (Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)); Exposed - BAT (sampling time is end of exposure or end of shift, measured as the metabolite, acetone), 50 mg/l; Toxic - Not established. Persons with pre existing skin disorders may be more susceptible to the effects of this agent. ... In persons with impaired pulmonary function, especially those with obstructive airway diseases, the breathing of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) might cause exacerbation of symptoms due to its irritant properties. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)'s production and use in the manufacture of acetone, glycerol, and isopropyl acetate and as a solvent for a variety of applications may result in its release to the environment through various waste streams. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)'s use in hydraulic fracturing fluids results in its direct release to the environment. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) has been identified as a metabolic product of aerobic microorganisms, anaerobic microorganisms, fungi, and yeast. If released to air, a vapor pressure of 45.4 mm Hg at 25 °C indicates Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) will exist solely as a vapor in the ambient atmosphere. Vapor-phase Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.2 days. If released to soil, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is expected to have very high mobility based upon an estimated Koc of 1.5. Volatilization from moist soil surfaces is expected to be an important fate process based upon a Henry's Law constant of 8.10X10-6 atm-cu m/mole. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 86 hours and 29 days, respectively. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to occur due to the lack of hydrolyzable functional groups. Biodegradation is expected to be an important fate process based on the results of microbial screening tests. Occupational exposure to Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) may occur through inhalation and dermal contact with this compound at workplaces where Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is produced or used. Monitoring data indicate that the general population may be exposed to Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) via inhalation of ambient air, ingestion of food and drinking water, and dermal contact with this compound directly and from consumer products containing Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA). ANAEROBIC: Typical Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) removal efficiencies for an anaerobic lagoon treatment facility, with a retention time of 15 days, were 50% after loading with dilute waste, and 69 and 74% after loading with concentrated wastes(1). In closed bottle studies, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) was completely degraded anaerobically by an acetate-enriched culture, derived from a seed of domestic sludge(1). The culture started to use cross-fed Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA), after 4 days, at a rate of 200 mg/L/day(1). In a mixed reactor with a 20-day retention time, seeded by the same culture, 56% removal was achieved in the 20 days following 70 days of acclimation to a final concentration of 10,000 mg/L(1). The avg percent removal of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) in semi-pilot scale anaerobic lagoons was 50% in 7.5-10 days for dilute wastes with 60 ppm Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and 69-74% in 20-40 days for concentrated wastes with 175 ppm Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)(2). Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) was readily mineralized to methane and carbon dioxide under methanogenic conditions(3). The degradation rate of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) under these conditions in fuel impacted river sediments and industrial/sewage impacted creek sediments was 2.4 ppm C/day (82% of expected methane recovery) and 3.0 ppm C/day (91% of expected methane recovery), respectively(3). The degradation rate of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) in a sediment slurry from a shallow anoxic aquifer under methanogenic conditions was 7.6 ppm C/day (112% of theoretical methane recovery)(4). In anaerobic bioreactor studies using a granular sludge inocula, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) (at 125 ppm initial concentration) degraded with 115.5% of theoretical methane production over a 21-day incubation period(5); acetone was identified as a metabolite(5). In laboratory anaerobic sludge reactor tests using liquid hen manure as inoculum, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) was degraded 100% in a 13-day incubation period with lag period(6). The Henry's Law constant for Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is 8.10X10-6 atm-cu m/mole at 25 °C(1). This Henry's Law constant indicates that Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 86 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 29 days(SRC). Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)'s Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is expected to volatilize from dry soil surfaces(SRC) based upon a vapor pressure of 45.2 mm Hg at 25 °C(3). The volatilization of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) from a runoff tank of an industrial wastewater treatment facility was measured; the volatilization rate of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) ranged between 0.64-0.69 mg/sq m-min(4). The evaporation rate of a 1:1 Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA):water mixture from a shallow pool was 1.5 kg/sq-m per hour at a wind speed of 4.5 m/s and pool temperature of 20 °C and an ambient air temperature of 22 °C(5). Laboratory studies demonstrated that Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) will volatilize from water to air in the absence of wind(6).

Based on the uses for isopropyl acetate the public could be exposed through: Workplace exposure.Exposure can occur either in an isopropyl acetate manufacturing facility or in the various industrial or manufacturing facilities that use it. Those working with isopropyl acetate in manufacturing operations could be exposed during maintenance, sampling, testing, or other procedures. Each facility should have a thorough training program for employees and appropriate work processes and safety equipment in place to limit unnecessary exposure. Consumer exposure to products containing isopropyl acetate for direct consumer use. Consumers could be exposed to isopropyl acetate by using cosmetics or other products containing it. See Health Information. Isopropyl acetate may be released to air by evaporation from products that contain it. Although the substance is moderately soluble, when introduced to water, it will have a tendency to evaporate. Because the chemical is highly biodegradable, it will be treated by sewage treatment plants. Large release - Industrial spills or releases are infrequent and generally contained. If a large spill does occur, dike the area to contain the spilled material. Isolate the area and evacuate unnecessary personnel. Eliminate all sources of ignition. Ground and bond all containers and handling equipment. In case of fire - Keep people away and prevent unnecessary entry. Isopropyl acetate vapor is an explosion hazard. Vapors are heavier than air and may travel long distances and accumulate in low-lying areas. Wear positive-pressure, self-contained breathing apparatus (SCBA) and protective fire-fighting clothing or fight fire from a safe distance. Use water fog or fine spray, dry-chemical or carbon-dioxide fire extinguishers, or foam. Do not use a direct water stream as it may spread the fire. Follow emergency procedures carefully. Eye and Skin Contact - Eye contact with liquid isopropyl acetate may cause severe irritation and severe corneal injury. Eye contact with vapor may cause mild discomfort and redness. Prolonged skin contact may cause slight irritation with local redness and discomfort and possible drying or flaking of the skin. Prolonged contact is unlikely to result in absorption of harmful amounts. Inhalation - Excessive inhalation of isopropyl acetate vapors may cause irritation to the nose, throat, and lungs, as well as central nervous system effects. In confined or poorly ventilated areas, unconsciousness or death could occur.Ingestion - Isopropyl acetate has very low toxicity if small amounts are swallowed. Cancer and Birth Defect Information - This material did not cause cancer in laboratory animals. In laboratory tests isopropyl acetate has been toxic to the fetus at doses toxic to the mother, but is not expected to interfere with reproduction.

Regulations may exist that govern the manufacture, sale, transportation, use, and/or disposal of isopropyl acetate. These regulations may vary by city, state, country, or geographic region. HAZARD SUMMARY * Isopropyl Acetate can affect you when breathed in. * Contact can irritate and burn the eyes. * Contact can cause severe skin burns. Repeated exposure can cause dryness and cracking of the skin. * Breathing Isopropyl Acetate can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. * High exposure can cause headache, drowsiness, poor muscle coordination, unconsciousness and coma. * Isopropyl Acetate may affect the liver. * Isopropyl Acetate is a FLAMMABLE LIQUID and a DANGEROUS FIRE HAZARD. IDENTIFICATION Isopropyl Acetate is a colorless liquid with a fruity odor. It is used as a solvent for cellulose, plastics, oils and fats, and in printing inks and perfume. HOW TO DETERMINE IF YOU ARE BEING EXPOSED The New Jersey Right to Know Act requires most employers to label chemicals in the workplace and requires public employers to provide their employees with information and training concerning chemical hazards and controls. The federal OSHA Hazard Communication Standard, 1910.1200, requires private employers to provide similar training and information to their employees. * Exposure to hazardous substances should be routinely evaluated. This may include collecting personal and area air samples. You can obtain copies of sampling results from your employer. You have a legal right to this information under OSHA 1910.1020. * If you think you are experiencing any work-related health problems, see a doctor trained to recognize occupational diseases. Take this Fact Sheet with you. * ODOR THRESHOLD = 4.1 ppm. * The range of accepted odor threshold values is quite broad. Caution should be used in relying on odor alone as a warning of potentially hazardous exposures. WORKPLACE EXPOSURE LIMITS OSHA: The legal airborne permissible exposure limit (PEL) is 250 ppm averaged over an 8-hour workshift. NIOSH: No exposure limit has been established. ACGIH: The recommended airborne exposure limit is 100 ppm averaged over an 8-hour workshift and 200 ppm as a STEL (short term exposure limit). WAYS OF REDUCING EXPOSURE * Where possible, enclose operations and use local exhaust ventilation at the site of chemical release. If local exhaust ventilation or enclosure is not used, respirators should be worn. * Wear protective work clothing. * Wash thoroughly immediately after exposure to Isopropyl Acetate and at the end of the workshift. * Post hazard and warning information in the work area. In addition, as part of an ongoing education and training effort, communicate all information on the health and safety hazards of Isopropyl acetate to potentially exposed workers. This Fact Sheet is a summary source of information of all potential and most severe health hazards that may result from exposure. Duration of exposure, concentration of the substance and other factors will affect your susceptibility to any of the potential effects described below. HEALTH HAZARD INFORMATION Acute Health Effects The following acute (short-term) health effects may ocur immediately or shortly after exposure to Isopropyl Acetate: * Contact can irritate and burn the eyes. * Contact can cause severe skin burns. * Breathing Isopropyl Acetate can irritate the nose, throat and lungs causing coughing, wheezing and/or shortness of breath. * High exposure can cause headache, drowsiness, poor muscle coordination, unconsciousness and coma. Chronic Health Effects The following chronic (long-term) health effects can occur at some time after exposure to Isopropyl Acetate and can last for months or years: Cancer Hazard * According to the information presently available to the New Jersey Department of Health and Senior Services, Isopropyl Acetate has not been tested for its ability to cause cancer in animals. Reproductive Hazard * According to the information presently available to the New Jersey Department of Health and Senior Services, Isopropyl Acetate has not been tested for its ability to affect reproduction. Other Long-Term Effects * Repeated exposure can cause dryness and cracking of the skin. * Isopropyl Acetate can irritate the lungs. Repeated exposure may cause bronchitis to develop with cough, phlegm, and/or shortness of breath. * Isopropyl Acetate may affect the liver. * This chemical has not been adequately evaluated to determine whether brain or other nerve damage could ocur with repeated exposure. However, many solvents and other petroleum-based chemicals have been shown to cause such damage. Effects may include reduced memory and concentration, personality changes (withdrawal, irritability), fatigue, sleep disturbances, reduced coordination, and/or effects on nerves supplying internal organs (autonomic nerves) and/or nerves to the arms and legs (weakness, "pins and needles"). MEDICAL Medical Testing If symptoms develop or overexposure is suspected, the following are recommended: * Lung function tests. * Liver function tests. * Evaluate for brain effects such as changes in memory, concentration, sleeping patterns and mood (especially irritability and social withdrawal), as well as headaches and fatigue. Consider evaluations of the cerebellar, autonomic and peripheral nervous systems. Positive and borderline individuals should be referred for neuropsychological testing. Any evaluation should include a careful history of past and present symptoms with an exam. Medical tests that look for damage already done are not a substitute for controlling exposure. Request copies of your medical testing. You have a legal right to this information under OSHA 1910.1020. Mixed Exposures * Because smoking can cause heart disease, as well as lung cancer, emphysema, and other espiratory problems, it may worsen respiratory conditions caused by chemical exposure. Even if you have smoked for a long time, stopping now will reduce your risk of developing health problems. * Because more than light alcohol consumption can cause liver damage, drinking alcohol may increase the liver damage caused by Isopropyl Acetate. WORKPLACE CONTROLS AND PRACTICES Unless a less toxic chemical can be substituted for a hazardous substance, ENGINEERING CONTROLS are the most effective way of reducing exposure. The best protection is to enclose operations and/or provide local exhaust ventilation at the site of chemical release. Isolating operations can also reduce exposure. Using respirators or protective equipment is less effective than the controls mentioned above, but is sometimes necessary. In evaluating the controls present in your workplace, consider: (1) how hazardous the substance is, (2) how much of the substance is released into the workplace and (3) whether harmful skin or eye contact could occur. Special controls should be in place for highly toxic chemicals or when significant skin, eye, or breathing exposures are possible. In addition, the following controls are recommended: * Where possible, automatically pump liquid Isopropyl Acetate from drums or other storage containers to process containers. * Before entering a confined space where Isopropyl Acetate may be present, check to make sure that an explosive concentration does not exist. Good WORK PRACTICES can help to reduce hazardous exposures. The following work practices are recommended: * Workers whose clothing has been contaminated by Isopropyl Acetate should change into clean clothing promptly. * Contaminated work clothes should be laundered by individuals who have been informed of the hazards of exposure to Isopropyl Acetate. * Eye wash fountains should be provided in the immediate work area for emergency use. * If there is the possibility of skin exposure, emergency shower facilities should be provided. * On skin contact with Isopropyl Acetate, immediately wash or shower to remove the chemical. At the end of the workshift, wash any areas of the body that may have contacted Isopropyl Acetate, whether or not known skin contact has occurred. * Do not eat, smoke, or drink where Isopropyl Acetate is handled, processed, or stored, since the chemical can be swallowed. Wash hands carefully before eating, drinking, smoking, or using the toilet. PERSONAL PROTECTIVE EQUIPMENT WORKPLACE CONTROLS ARE BETTER THAN PERSONAL PROTECTIVE EQUIPMENT. However, for some jobs (such as outside work, confined space entry, jobs done only once in a while, or jobs done while workplace controls are being installed), personal protective equipment may be appropriate. OSHA 1910.132 requires employers to determine the appropriate personal protective equipment for each hazard and to train employees on how and when to use protective equipment. The following recommendations are only guidelines and may not apply to every situation. Clothing * Avoid skin contact with Isopropyl Acetate. Wear solventresistant gloves and clothing. Safety equipment suppliers/ manufacturers can provide recommendations on the most protective glove/clothing material for your operation. * All protective clothing (suits, gloves, footwear, headgear) should be clean, available each day, and put on before work. Eye Protection * Wear indirect-vent, impact and splash resistant goggles when working with liquids. * Wear a face shield along with goggles when working with corrosive, highly irritating or toxic substances. * Contact lenses should not be worn when working with this substance. Respiratory Protection IMPROPER USE OF RESPIRATORS IS DANGEROUS. Such equipment should only be used if the employer has a written program that takes into account workplace conditions, requirements for worker training, respirator fit testing and medical exams, as described in OSHA 1910.134. * Where the potential exists for exposure over 100 ppm, use a NIOSH approved supplied-air respirator with a full facepiece operated in a pressure-demand or other positivepressure mode. For increased protection use in combination with an auxiliary self-contained breathing apparatus operated in a pressure-demand or other positive-pressure mode. * Exposure to 1,800 ppm is immediately dangerous to life and health. If the possibility of exposure above 1,800 ppm exists, use a NIOSH approved self-contained breathing apparatus with a full facepiece operated in a pressuredemand or other positive-pressure mode equipped with an emergency escape air cylinder. HANDLING AND STORAGE * Prior to working with Isopropyl Acetate you should be trained on its proper handling and storage. * Isopropyl Acetate is not compatible with OXIDIZING AGENTS (such as PERCHLORATES, PEROXIDES, PERMANGANATES, CHLORATES, NITRATES, CHLORINE, BROMINE and FLUORINE); STRONG ACIDS (such as HYDROCHLORIC, SULFURIC and NITRIC); STRONG BASES (such as SODIUM HYDROXIDE and POTASSIUM HYDROXIDE); and COMBUSTIBLE MATERIALS. * Store in tightly closed containers in a cool, well-ventilated area away from MOISTURE and HEAT. * Sources of ignition, such as smoking and open flames, are prohibited where Isopropyl Acetate is used, handled, or stored. * Metal containers involving the transfer of Isopropyl Acetate should be grounded and bonded. * Use only non-sparking tools and equipment, especially when opening and closing containers of Isopropyl Acetate. Q: When are higher exposures more likely? A: Conditions which increase risk of exposure include physical and mechanical processes (heating, pouring, spraying, spills and evaporation from large surface areas such as open containers), and "confined space" exposures (working inside vats, reactors, boilers, small rooms, etc.). Q: Is the risk of getting sick higher for workers than for community residents? A: Yes. Exposures in the community, except possibly in cases of fires or spills, are usually much lower than those found in the workplace. However, people in the community may be exposed to Contaminated water as well as to chemicals in the air over long periods. This may be a problem for Industrial Hygiene Information Industrial hygienists are available to answer your questions regarding the control of chemical exposures using exhaust ventilation, special work practices, good housekeeping, good hygiene practices, and personal protective equipment including respirators. In addition, they can help to interpret the results of industrial hygiene survey data. Medical Evaluation If you think you are becoming sick because of exposure to chemicals at your workplace, you may call personnel at the Department of Health and Senior Services, Occupational Health Service, who can help you find the information you need. Public Presentations Presentations and educational programs on occupational health or the Right to Know Act can be organized for labor unions, trade associations and other groups.

Isopropyl Alcohol Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is an organic compound, an isomer of n-propanol, aliased dimethylmethanol, 2-propanol. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is a colorless, transparent liquid with a scent like a mixture of ethanol and acetone. Soluble in water, also soluble in most organic solvents such as alcohol, ether, benzene, chloroform, etc. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) has a wide range of uses as an organic raw material and solvent. 1)As a chemical raw material, it can produce acetone, hydrogen peroxide, methyl isobutyl ketone, diisobutyl ketone, isopropylamine, diisopropyl ether, isopropyl chloride, and fatty acid isopropyl ester and chloro fatty acid isopropyl ester. 2)In the fine chemical industry, it can be used to produce isopropyl nitrate, isopropyl xanthate, triisopropyl phosphite, aluminum isopropoxide, pharmaceuticals and pesticides, etc. It can also be used to produce diisopropanone, isopropyl acetate and Thymol and gasoline additives. 3)Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Can be used to produce coatings, inks, extractants, aerosols, etc. 4) In the electronics industry, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) can be used as a cleaning and degreasing agent. 5) In the oil and fat industry, the extractant of cottonseed oil can also be used for degreasing of animal-derived tissue membranes. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) (IUPAC name propan-2-ol; commonly called isopropanol or 2-propanol) is a colorless, flammable chemical compound (chemical formula CH3CHOHCH3) with a strong odor.[8] As an isopropyl group linked to a hydroxyl group, it is the simplest example of a secondary alcohol, where the alcohol carbon atom is attached to two other carbon atoms. It is a structural isomer of 1-propanol and ethyl methyl ether. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is used in the manufacture of a wide variety of industrial and household chemicals and is a common ingredient in chemicals such as antiseptics, disinfectants, and detergents. Names of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is also known as 2-propanol, sec-propyl alcohol, IPA, or isopropanol. IUPAC considers isopropanol an incorrect name as the hydrocarbon isopropane does not exist. Properties of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is miscible in water, ethanol, ether, and chloroform. It dissolves ethyl cellulose, polyvinyl butyral, many oils, alkaloids, gums and natural resins.[9] Unlike ethanol or methanol, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is not miscible with salt solutions and can be separated from aqueous solutions by adding a salt such as sodium chloride. The process is colloquially called salting out, and causes concentrated Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) to separate into a distinct layer. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) forms an azeotrope with water, which gives a boiling point of 80.37 °C (176.67 °F) and a composition of 87.7 wt% (91 vol%) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA). Water–Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) mixtures have depressed melting points.[10] It has a slightly bitter taste, and is not safe to drink. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) becomes increasingly viscous with decreasing temperature and freezes at −89 °C (−128 °F). Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) has a maximal absorbance at 205 nm in an ultraviolet–visible spectrum. Reactions of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) can be oxidized to acetone, which is the corresponding ketone. This can be achieved using oxidizing agents such as chromic acid, or by dehydrogenation of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) over a heated copper catalyst: (CH3)2CHOH → (CH3)2CO + H2 Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is often used as both solvent and hydride source in the Meerwein-Ponndorf-Verley reduction and other transfer hydrogenation reactions. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) may be converted to 2-bromopropane using phosphorus tribromide, or dehydrated to propene by heating with sulfuric acid. Like most alcohols, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) reacts with active metals such as potassium to form alkoxides that can be called isopropoxides. The reaction with aluminium (initiated by a trace of mercury) is used to prepare the catalyst aluminium isopropoxide.[14] History of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) In 1920, Standard Oil first produced Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) by hydrating propene. Its major use at the time was not rubbing alcohol but for oxidation to acetone, whose first major use was in World War I for the preparation of cordite, a smokeless, low explosive propellant. Production of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) In 1994, 1.5 million tonnes of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) were produced in the United States, Europe, and Japan.[16] It is primarily produced by combining water and propene in a hydration reaction or by hydrogenating acetone. There are two routes for the hydration process and both processes require that the Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) be separated from water and other by-products by distillation. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and water form an azeotrope, and simple distillation gives a material that is 87.9% by weight Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and 12.1% by weight water.[18] Pure (anhydrous) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is made by azeotropic distillation of the wet Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) using either diisopropyl ether or cyclohexane as azeotroping agents.[16] Biological of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Small amounts of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) are produced in the body in diabetic ketoacidosis.[19] Indirect hydration of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Indirect hydration reacts propene with sulfuric acid to form a mixture of sulfate esters. This process can use low-quality propene, and is predominant in the USA. These processes give primarily Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) rather than 1-propanol, because adding water or sulfuric acid to propene follows Markovnikov's rule. Subsequent hydrolysis of these esters by steam produces Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA), by distillation. Diisopropyl ether is a significant by-product of this process; it is recycled back to the process and hydrolyzed to give the desired product. CH3CH=CH2 + H2O H2SO4⟶ (CH3)2CHOH Direct hydration of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) See also: Heteropoly acid Direct hydration reacts propene and water, either in gas or liquid phase, at high pressures in the presence of solid or supported acidic catalysts. This type of process usually requires higher-purity propylene (> 90%).[16] Direct hydration is more commonly used in Europe. Hydrogenation of acetone Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) may be prepared via the hydrogenation of acetone, however this approach involves an extra step compared to the above methods, as acetone is itself normally prepared from propene via the cumene process.[16] It may remain economical depending on the value of the products. A known issue is the formation of MIBK and other self-condensation products. Raney nickel was one of the original industrial catalysts, modern catalysts are often supported bimetallic materials. This is an efficient process and easy Uses of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) One of the small scale uses of isopropanol is in cloud chambers. Isopropanol has ideal physical and chemical properties to form a supersaturated layer of vapor which can be condensed by particles of radiation. In 1990, 45,000 metric tonnes of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) were used in the United States, mostly as a solvent for coatings or for industrial processes. In that year, 5400 metric tonnes were used for household purposes and in personal care products. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is popular in particular for pharmaceutical applications,[16] due to its low toxicity. Some Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is used as a chemical intermediate. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) may be converted to acetone, but the cumene process is more significant. [16] Solvent of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) dissolves a wide range of non-polar compounds. It also evaporates quickly, leaves nearly zero oil traces, compared to ethanol, and is relatively non-toxic, compared to alternative solvents. Thus, it is used widely as a solvent and as a cleaning fluid, especially for dissolving oils. Together with ethanol, n-butanol, and methanol, it belongs to the group of alcohol solvents, about 6.4 million tonnes of which were used worldwide in 2011.[20] Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is commonly used for cleaning eyeglasses, electrical contacts, audio or video tape heads, DVD and other optical disc lenses, removing thermal paste from heatsinks on CPUs and other IC packages, etc. Intermediate Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is esterified to give isopropyl acetate, another solvent. It reacts with carbon disulfide and sodium hydroxide to give sodium isopropylxanthate, a herbicide and an ore flotation reagent.[21] Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) reacts with titanium tetrachloride and aluminium metal to give titanium and aluminium isopropoxides, respectively, the former a catalyst, and the latter a chemical reagent.[16] This compound may serve as a chemical reagent in itself, by acting as a dihydrogen donor in transfer hydrogenation. Medical of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Rubbing alcohol, hand sanitizer, and disinfecting pads typically contain a 60–70% solution of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) or ethanol in water. Water is required to open up membrane pores of bacteria, which acts as a gateway for Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA). A 75% v/v solution in water may be used as a hand sanitizer.[22] Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is used as a water-drying aid for the prevention of otitis externa, better known as swimmer's ear.[23] Early uses as an anesthetic Although Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) can be used for anesthesia, its many negative attributes or drawbacks prohibit this use. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) can also be used similarly to ether as a solvent[24] or as an anesthetic by inhaling the fumes or orally. Early uses included using the solvent as general anesthetic for small mammals[25] and rodents by scientists and some veterinarians. However, it was soon discontinued, as many complications arose, including respiratory irritation, internal bleeding, and visual and hearing problems. In rare cases, respiratory failure leading to death in animals was observed. Automotive Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is a major ingredient in "gas dryer" fuel additives. In significant quantities, water is a problem in fuel tanks, as it separates from gasoline and can freeze in the supply lines at low temperatures. Alcohol does not remove water from gasoline, but the alcohol solubilizes water in gasoline. Once soluble, water does not pose the same risk as insoluble water, as it no longer accumulates in the supply lines and freezes but is consumed with the fuel itself. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is often sold in aerosol cans as a windshield or door lock deicer. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is also used to remove brake fluid traces from hydraulic braking systems, so that the brake fluid (usually DOT 3, DOT 4, or mineral oil) does not contaminate the brake pads and cause poor braking. Mixtures of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and water are also commonly used in homemade windshield washer fluid. Laboratory As a biological specimen preservative, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) provides a comparatively non-toxic alternative to formaldehyde and other synthetic preservatives. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) solutions of 70–99% are used to preserve specimens. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is often used in DNA extraction. A lab worker adds it to a DNA solution to precipitate the DNA, which then forms a pellet after centrifugation. This is possible because DNA is insoluble in Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA). Safety of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) vapor is denser than air and is flammable, with a flammability range of between 2 and 12.7% in air. It should be kept away from heat and open flame.[26] Distillation of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) over magnesium has been reported to form peroxides, which may explode upon concentration. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is a skin irritant. Wearing protective gloves is recommended. Toxicology of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and its metabolite, acetone, act as central nervous system (CNS) depressants.[31] Poisoning can occur from ingestion, inhalation, or skin absorption. Symptoms of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) poisoning include flushing, headache, dizziness, CNS depression, nausea, vomiting, anesthesia, hypothermia, low blood pressure, shock, respiratory depression, and coma.[31] Overdoses may cause a fruity odor on the breath as a result of its metabolism to acetone.[32] Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) does not cause an anion gap acidosis but it produces an osmolal gap between the calculated and measured osmolalities of serum, as do the other alcohols.[31] Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is oxidized to form acetone by alcohol dehydrogenase in the liver,[31] and has a biological half-life in humans between 2.5 and 8.0 hours.[31] Unlike methanol or ethylene glycol poisoning, the metabolites of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) are considerably less toxic, and treatment is largely supportive. Furthermore, there is no indication for the use of fomepizole, an alcohol dehydrogenase inhibitor, unless co-ingestion with methanol or ethylene glycol is suspected. In forensic pathology, people who have died as a result of diabetic ketoacidosis usually have blood concentrations of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) of tens of mg/dL, while those by fatal Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) ingestion usually have blood concentrations of hundreds of mg/dL. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) will attack some forms of plastics, rubber, and coatings. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is an isomer of propyl alcohol with antibacterial properties. Although the exact mechanism of isopropanol's disinfecting action is not known, it might kill cells by denaturing cell proteins and DNA, interfering with cellular metabolism, and dissolving cell lipo-protein membranes. Isopropanol is used in soaps and lotions as an antiseptic. Any clothing which becomes wet with liquid Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) should be removed immediately and not reworn until the Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is removed from the clothing. Clothing should then be placed in closed containers for storage until it can be discarded or until provision can be made for the removal of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) from the clothing. If the clothing is to be laundered or otherwise cleaned to remove the Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA), the person performing the operation should be informed of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)'s hazardous properties. When a stream of hydrogen entrained Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) vapors and palladium particles, the mixture caught fire on exposure to air. Solutions of 90% nitroform in 10% Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) in polyethylene bottles exploded. The reaction between Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and phosgene forms isopropyl chloroformate and hydrogen chloride. In the presence of iron salts thermal decomposition can occur, which in some cases can become explosive. Mixing oleum and Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) in a closed container caused the temperature and pressure to increase. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) (without residue) may be used in inks for marking food supplements in tablet form, gum, and confectionery. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) may be present in the following foods under the conditions specified: (a) In spice oleoresins as a residue from the extraction of spice, at a level not to exceed 50 parts per million. (b) In lemon oil as a residue in production of the oil, at a level not to exceed 6 parts per million. (c) In hops extract as a residue from the extraction of hops at a level not to exceed 2.0 percent by weight: Provided, that, (1) The hops extract is added to the wort before or during cooking in the manufacture of beer. (2) The label of the hops extract specifies the presence of the Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and provides for the use of the hops extract only as prescribed by paragraph (c)(1) of this section. WORKERS IN AN Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) PACKAGING PLANT BECAME ILL AFTER ACCIDENTAL EXPOSURE TO CARBON TETRACHLORIDE. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) POTENTIATION OF CARBON TETRACHLORIDE TOXICITY HAS BEEN SHOWN PREVIOUSLY ONLY IN RATS. ACETONE, A PRODUCT OF Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) METABOLISM, IS A MAJOR POTENTIATOR OF CARBON TETRACHLORIDE TOXICITY. IDENTIFICATION: Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is an aliphatic alcohol hydrocarbon. It is prepared from propylene, which is obtained in the cracking of petroleum or by the reduction of acetone. It is a colorless liquid which is soluble in water, alcohol, ether, acetone, benzene and chloroform. It is insoluble in salt solutions. It has a slight odor resembling a mixture of ethanol and acetone and has a slight bitter taste. It is used in antifreeze, industrial solvent, solvent for gums, shellac, essential oils, in quick drying oils, creosote and resins; extraction of alkaloids; in quick drying inks; in denaturing ethyl alcohol; in body rubs, hand lotions, after shave lotions, cosmetics and pharmaceuticals; in manufacture of acetone, glycerol, isopropyl acetate; antiseptic; rubefacient ; and pharmaceutical aid. HUMAN EXPOSURE: Toxic effects include central nervous depression, liver, kidney, cardiovascular depression and brain damage. It can cause drowsiness, ataxia, stupor, coma and respiratory depression, irritation of mucous membranes and eyes, gastritis, gastric hemorrhage, vomiting, pancreatitis, cold clammy skin, hypothermia, miosis, tachycardia, slow and noisy respiration. High risk of circumstances of poisoning: Accidental ingestion of rubbing alcohols/toiletries by children. There is a potential exposure from dermal and inhalation exposure in children during Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) sponging for control of fever. Intentional ingestion for alcoholic effect or in suicide attempts. Occupational or accidental exposure to liquid or its vapor in industrial applications. Individuals exposed to Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) include the following: workers in the pharmaceutical industry, cosmetic industry, chemical industry, petroleum workers, laboratory workers, printers, painters and carpenters and cabinet makers. There is little absorption through intact skin. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is a potent eye and skin irritant. 80% of an oral dose is absorbed within 30 minutes. Absorption is complete within 2 hours although this may be delayed in a large overdose. Alveolar concentration is correlated to the environmental concentration at any given time. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is absorbed through intact skin on prolonged exposure. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) distributes in body water with an apparent volume of distribution of 0.6-0.7 L/kg. 20-50% of an absorbed dose is excreted unchanged. Most Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is oxidized in the liver by alcohol dehydrogenase to acetone, formate and finally carbon dioxide. Acetone is slowly eliminated by the lung (40%) or kidney. Clinically insignificant excretion occurs into the stomach and saliva. Related keto acids are not produced in sufficient quantities to cause a severe metabolic acidosis. Inebriation, peripheral vasodilation has occurred. In children, hypoglycemia is particularly severe when poisoning following fasting, exercise or chronic malnutrition Lactic acidosis may occur in patients with severe liver disease, pancreatitis or receiving biguanide therapy or as a result of the hypovolemia which frequently accompanies severe intoxication. ANIMAL STUDIES: Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) most closely follows first order kinetics, with a half life of 2.5 to 3.2 hours. The elimination half life of the active metabolite acetone is significantly prolonged to about 5 hours in rats. In rat hepatocytes the following has been observed: marked depletion of glutathione, increased malondialdehyde production, decreased protein sulfhydryls content and leakage of lactic dehydrogenase with loss of membrane activity. A complete history and physical examination should be performed to detect pre existing conditions that might place the employee at increased risk, and to establish a baseline for future health monitoring. Examination of the skin, liver, kidneys, and respiratory system should be stressed. Skin disease: Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is a defatting agent and can cause dermatitis on prolonged exposure. Persons with pre existing skin disorders may be more susceptible to the effects of this agent. Liver disease: Although Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is not known as a liver toxin in humans, the importance of this organ in the biotransformation and detoxification of foreign substances should be considered before exposing persons with impaired liver function. Kidney disease: Although Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is not known as a kidney toxin in humans, the importance of this organ in the elimination of toxic substances justifies special consideration in those with impaired renal function. Chronic respiratory disease: In persons with impaired pulmonary function, especially those with obstructive airway diseases, the breathing of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) might cause exacerbation of symptoms due to its irritant properties. Periodic Medical Examination: The aforementioned medical examinations should be repeated on an annual basis. The assessment of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) exposure can be accomplished through measurement of either Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) or acetone. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) measurement has not been found to be a good assessment of low level exposure, due to its low sensitivity. However, measurement of acetone has been found to be a good indicator of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) exposure for exposures as low as 70 ppm, and has been found to correlate well with air concentrations. Whole Blood Reference Ranges: Normal - none detected (Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)); Exposed - BAT (sampling time is end of exposure or end of shift, measured as the metabolite, acetone), 50 mg/l; Toxic - Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) level associated with serious toxic symptoms is 150 mg/l. Serum or Plasma Reference Ranges: Normal - none detected (Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)); Exposed - not established; and Toxic - not established. Urine Reference Ranges: The assessment of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) exposure can be accomplished through measurement of either Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) or acetone. However only acetone was found to be a useful test, due to its greater sensitivity and good correlation with air exposure levels. Normal - none detected (Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)); Exposed - BAT (sampling time is end of exposure or end of shift, measured as the metabolite, acetone), 50 mg/l; Toxic - Not established. Persons with pre existing skin disorders may be more susceptible to the effects of this agent. ... In persons with impaired pulmonary function, especially those with obstructive airway diseases, the breathing of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) might cause exacerbation of symptoms due to its irritant properties. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)'s production and use in the manufacture of acetone, glycerol, and isopropyl acetate and as a solvent for a variety of applications may result in its release to the environment through various waste streams. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)'s use in hydraulic fracturing fluids results in its direct release to the environment. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) has been identified as a metabolic product of aerobic microorganisms, anaerobic microorganisms, fungi, and yeast. If released to air, a vapor pressure of 45.4 mm Hg at 25 °C indicates Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) will exist solely as a vapor in the ambient atmosphere. Vapor-phase Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) will be degraded in the atmosphere by reaction with photochemically-produced hydroxyl radicals; the half-life for this reaction in air is estimated to be 3.2 days. If released to soil, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is expected to have very high mobility based upon an estimated Koc of 1.5. Volatilization from moist soil surfaces is expected to be an important fate process based upon a Henry's Law constant of 8.10X10-6 atm-cu m/mole. Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is expected to volatilize from dry soil surfaces based upon its vapor pressure. If released into water, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is not expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is expected to be an important fate process based upon this compound's Henry's Law constant. Estimated volatilization half-lives for a model river and model lake are 86 hours and 29 days, respectively. An estimated BCF of 3 suggests the potential for bioconcentration in aquatic organisms is low. Hydrolysis is not expected to occur due to the lack of hydrolyzable functional groups. Biodegradation is expected to be an important fate process based on the results of microbial screening tests. Occupational exposure to Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) may occur through inhalation and dermal contact with this compound at workplaces where Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is produced or used. Monitoring data indicate that the general population may be exposed to Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) via inhalation of ambient air, ingestion of food and drinking water, and dermal contact with this compound directly and from consumer products containing Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA). ANAEROBIC: Typical Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) removal efficiencies for an anaerobic lagoon treatment facility, with a retention time of 15 days, were 50% after loading with dilute waste, and 69 and 74% after loading with concentrated wastes(1). In closed bottle studies, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) was completely degraded anaerobically by an acetate-enriched culture, derived from a seed of domestic sludge(1). The culture started to use cross-fed Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA), after 4 days, at a rate of 200 mg/L/day(1). In a mixed reactor with a 20-day retention time, seeded by the same culture, 56% removal was achieved in the 20 days following 70 days of acclimation to a final concentration of 10,000 mg/L(1). The avg percent removal of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) in semi-pilot scale anaerobic lagoons was 50% in 7.5-10 days for dilute wastes with 60 ppm Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) and 69-74% in 20-40 days for concentrated wastes with 175 ppm Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)(2). Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) was readily mineralized to methane and carbon dioxide under methanogenic conditions(3). The degradation rate of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) under these conditions in fuel impacted river sediments and industrial/sewage impacted creek sediments was 2.4 ppm C/day (82% of expected methane recovery) and 3.0 ppm C/day (91% of expected methane recovery), respectively(3). The degradation rate of Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) in a sediment slurry from a shallow anoxic aquifer under methanogenic conditions was 7.6 ppm C/day (112% of theoretical methane recovery)(4). In anaerobic bioreactor studies using a granular sludge inocula, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) (at 125 ppm initial concentration) degraded with 115.5% of theoretical methane production over a 21-day incubation period(5); acetone was identified as a metabolite(5). In laboratory anaerobic sludge reactor tests using liquid hen manure as inoculum, Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) was degraded 100% in a 13-day incubation period with lag period(6). The Henry's Law constant for Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is 8.10X10-6 atm-cu m/mole at 25 °C(1). This Henry's Law constant indicates that Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA) is expected to volatilize from water surfaces(2). Based on this Henry's Law constant, the volatilization half-life from a model river (1 m deep, flowing 1 m/sec, wind velocity of 3 m/sec)(2) is estimated as 86 hours(SRC). The volatilization half-life from a model lake (1 m deep, flowing 0.05 m/sec, wind velocity of 0.5 m/sec)(2) is estimated as 29 days(SRC). Isopropyl alcohol (izopropil alkol, isopropyl alcohol, IPA)'s Henry's Law constant indicates that volatilization from moist soil surfaces may occur(SRC). Isopropyl alcohol (izopropil

Ethylhexyl Stearate may also be called Octyl Stearate. In cosmetics and personal care products, stearate esters are used most frequently in the formulation of eye makeup, skin makeup, lipstick and skin care products. Stearate esters act primarily as lubricants on the skin's surface, which gives the skin a soft and smooth appearance. Butyl Stearate also decreases the thickness of lipsticks, thereby lessening the drag on lips, and imparts water repelling characteristics to nail polishes. Butyl Stearate and Isopropyl Stearate dry to form a thin coating on the skin. Isocetyl Stearate can also be used to dissolve other substances, usually liquids.

This product does not modify pigment coloration, and provides superfatting properties to compensate for the drying effect of powders. Skincare ingredients: Isostearyl Isostearate What is Isostearyl isostearate? Great for: Emollient like jojoba oil with a virtually non-existent after-feel How it works: It provides a rich but non-greasy skin feel and improves spreading on the skin. It is often used in lipsticks and to bind together make-up powders. Where does isostearyl isostearate come from? Isostearyl isostearate is the ester (the product of an alcohol and an acid) of isosteric alcohol and isostearic acid. Isostearic acid is an isomer of stearic acid, a naturally-occurring fatty acid found in cocoa and shea butter. Isostearic acid and stearic acid have the same chemical formula, but the arrangement of their atoms vary slightly which gives it very different physical properties. For example, stearic acid is solid at room temperature and isostearic acid is clear yellow liquid. Formulation tips Undiluted Isopropyl Isostearate was classified as a slight ocular irritant but otherwise is considered very safe.

Isotridecanol (ITDA) is an organic-chemical compound from the group of alcohols.
Under normal conditions, isotridecanol is a colorless, weakly smelling liquid that is insoluble in water.

The highly pure C13 alcohol is an important intermediate product in the production of surface-active substances, so-called surfactants.
The term iso refers to the methyl group on the penultimate carbon atom and on the end opposite the OH group Branched C12 carbon chain.
The correct systematic name is therefore 11-methyl-1-dodecanol.

Isotridecanol is regarded as a real petrochemical specialty and is launched as a particularly high-quality product with an almost 100% content of C13 alcohols.


Isotrideconal is used, among other things, as an intermediate in the manufacture of surfactants and plasticizers.
Isotrideconal is often used in high-quality industrial applications, e.g. in the production of cleaning agents and lubricants.
Another application of Isotrideconal is in the form of special esters in high-quality lacquers and lacquer resins.
In addition, isotridecanol may also be used in the EU as a fragrance in cosmetic articles and preparations using the INCI name of the same name.

Isotrideconal has a general purpose as a dispersant and emulsifier with good wetting properties.

Product Description
Exxal alcohols are isomeric branched, primary alcohols that contain both even- and odd-numbered hydrocarbon chains, ranging from C8 to C13.

In general, there are two main types of structures in industrial alcohols:

Linear (or straight-chain) molecules: obtained from synthetic or natural sources
Branched chain alcohols: produced from propylene and butene

Our customers use Exxal alcohols to synthesize derivatives used in industrial applications:

Surfactants – industrial applications, cleaning, and oil and gas

Polymer additives – stabilizers, antioxidants and flame retardants
Adhesives – acrylates

Lube and fuel additives
Lubricant esters

They are also used as solvents or cosolvents for coatings, inks and metal extraction in mining.

Benefits

High-purity Exxal alcohols exhibit reactivity typical of higher primary alcohols. Thanks to their branched structure, Exxal alcohols offer many performance advantages to ethoxylates compared to linear alcohol-based ones:

Low pour point – prohibits gel and wax formation, facilitates processing of alcohols and derivatives
Biodegradability – all of our alcohols and their ethoxylates meet the OECD 301F readily biodegradable threshold for isomeric mixtures
Superior wetting power of derived surfactants – excellent candidates for resource extraction and nonylphenol substitution
Powerful solvency in coatings and inks, fully soluble in hydrocarbon fluids while enhancing their solvency power
Wide viscosity ranges in synlubes

The stearate esters (Butyl Stearate, Cetyl Stearate, Isocetyl Stearate, Isopropyl Stearate, Myristyl Stearate, Ethylhexyl Stearate, Isobutyl Stearate) are oily liquids or waxy solids.
Ethylhexyl Stearate may also be called Octyl Stearate. In cosmetics and personal care products, stearate esters are used most frequently in the formulation of eye makeup, skin makeup, lipstick and skin care products.
Why is it used in cosmetics and personal care products?
Stearate esters act primarily as lubricants on the skin's surface, which gives the skin a soft and smooth appearance.
Butyl Stearate also decreases the thickness of lipsticks, thereby lessening the drag on lips, and imparts water-repelling characteristics to nail polishes.
Butyl Stearate and Isopropyl Stearate dry to form a thin coating on the skin. Isocetyl Stearate can also be used to dissolve other substances, usually liquids.

Scientific Facts:
The stearate esters are prepared by reacting stearic acid with the appropriate alcohol (butyl, cetyl, isobutyl, isocetyl, isopropyl, myristyl or ethylhexyl alcohol).
Stearate esters have the unique properties of low viscosity and oily nature, which results in a nongreasy, hydrophobic film when applied to the skin or lips.
Stearic acid is found in animal and vegetable fats.

Function in the product
Affects the application properties of cosmetics - gives a good glide when spreading (e.g. lipsticks on the lips), reduces sticking and greasiness of the cosmetic. Stick plasticizer - gives the sticks elasticity, prevents them from crushing.

Cosmetic action
Used in skin and hair care preparations, it creates an occlusive layer on the surface, which prevents excessive evaporation of water from the surface (indirect moisturizing effect), thus conditioning, i.e. softening and smoothing the skin and hair.

ITACONIC ACID
Itaconic Acid Itaconic acid, or methylidenesuccinic acid, is an organic compound. This dicarboxylic acid is a white solid that is soluble in water, ethanol, and acetone. Historically, itaconic acid was obtained by the distillation of citric acid, but currently it is produced by fermentation. The name itaconic acid was devised as an anagram of aconitic acid, another derivative of citric acid. Production Since the 1960s, it is produced industrially by the fermentation of carbohydrates such as glucose or molasses using fungi such as Aspergillus itaconicus or Aspergillus terreus. For A. terreus the itaconate pathway is mostly elucidated. The generally accepted route for itaconate is via glycolysis, tricarboxylic acid cycle, and a decarboxylation of cis-aconitate to itaconate via cis-aconitate-decarboxylase. The smut fungus Ustilago maydis uses an alternative route. Cis-aconitate is converted to the thermodynamically favoured trans-aconitate via aconitate-Δ-isomerase (Adi1). trans-Aconitate is further decarboxylated to itaconate by trans-aconitate-decarboxylase (Tad1). Itaconic acid is also produced in cells of macrophage lineage. It was shown that itaconate is a covalent inhibitor of the enzyme isocitrate lyase in vitro. As such, itaconate may possess antibacterial activities against bacteria expressing isocitrate lyase (such as Salmonella enterica and Mycobacterium tuberculosis). However, cells of macrophage lineage have to "pay the price" for making itaconate, and they lose the ability to perform mitochondrial substrate-level phosphorylation. Laboratory synthesis Dry distillation of citric acid affords itaconic anhydride, which undergoes hydrolysis to itaconic acid. Reactions Upon heating, itaconic anhydride isomerizes to citraconic acid anhydride, which can be hydrolyzed to citraconic acid (2-methylmaleic acid). Steps in conversion of citric acid to citraconic acid via itaconic and aconitic acids. Partial hydrogenation of itaconic acid over Raney nickel affords 2-methylsuccinic acid. Itaconic acid is primarily used as a co-monomer in the production of acrylonitrile butadiene styrene and acrylate latexes with applications in the paper and architectural coating industry. Properties and Application of Itaconic Acid Itaconic acid is a white crystalline powder having a hygroscopic property and a specific odor. Its melting point is 167–168 °C and the boiling point is 268 °C. Water solubility is 83.1 g l−1, and a solution (80 mg l−1) of itaconic acid in pure water has a pH of 2.0. The density of itaconic acid is 1.63 (20 °C). The pKa values of itaconic acid, its two dissociation steps, are 3.84 and 5.55 (25 °C). The equilibrium constants are K1 = 1.4 × 10−4 and K2 = 3.6 × 10−6 (25 °C). Itaconic acid is mainly used in the plastic and paint industry. It is an unsaturated dicarbonic acid, and can readily be incorporated into polymers and used at a concentration of 1–5% (w/w) as a comonomer in polymers. The polymerized methyl, ethyl, or vinyl esters of itaconic acid are used as plastics, adhesives elastomers, and coatings. Styrene butadiene copolymers containing itaconic acid yield rubber-like resins of excellent strength and flexibility and water-proofing coatings with good electrical insulation. Other fields for use are synthetic fibers, lattices, detergents, and cleaners. On the other hand, several mono- and diesters of partially substituted itaconic acid possess anti-inflammatory or analgesic activities, and a special new market has opened for the use of itaconic acid pharmaceutical fields. A small quantity of itaconic acid is used as acidulant. Itaconic acid (2-methylenesuccinic acid, 1-propene-2–3-dicarboxylic acid) is an unsaturated, weak dicarboxylic acid (pKa =3.83 and 5.41), discovered in 1837 as a thermal decomposition product of citric acid. The presence of the conjugated double bond of the methylene group allows polymerization both by addition and condensation. Esterification of the two carboxylic groups with different co-monomers is also possible (Kuenz et al., 2012). These diverse properties have led to a variety of applications in the pharmaceutical, architectural, paper, paint, and medical industries such as plastics, resins, paints, synthetic fibers, plasticizers, and detergents. Recently, itaconic acid applications have penetrated the dental, ophthalmic and drug delivery fields (Hajian and Yusoff, 2015). Itaconic acid polymers could even replace the petroleum-based polyacrylic acid, which has a multi-billion dollar market (Saha et al., 2019). Not surprisingly, the US Department of Energy assigned itaconic acid as one of the top 12 most promising building block chemicals for bio-based economy in 2004 (Werpy and Petersen, 2004). Little is known about the reasons why fungi produce itaconate. Like the other organic acids, as outlined above, also itaconic acid might serve as acidifier of the environment and thus provide selective advantage for the acid-tolerant A. terreus over other micro-organisms. However, itaconic acid also has clear inhibitory properties: in macrophages of mammals, bacterial infection prompts the induction of a gene encoding a cis-aconitate decarboxylase, resulting in itaconic acid formation that inhibits bacterial metabolism as part of the immune response. The effect has been attributed to the inhibition of succinate dehydrogenase and isocitrate lyase (McFadden et al., 1971), the latter being a key enzyme of the glyoxylate cycle, required for the survival of pathogens inside a host. In turn, a few strains of these bacteria have evolved to be capable of degrading itaconate (Sasikaran et al., 2014). Itaconic acid also induces a transcription factor which is essential for protection against oxidative and xenobiotic stresses, and to attenuate inflammation (Kobayashi et al., 2013; Bambouskova et al., 2018). Whether a similar function of itaconate exists in the fungi producing it has not yet been studied. The biosynthetic pathway of itaconic acid resembles that of citric acid, the latter acid being a direct precursor of the former. The only difference is that citric acid in A. terreus is further metabolized via cis-aconitate to itaconate by cis-aconitate decarboxylase (Bonnarme et al., 1995). To this end, cis-aconitate is transported out of the mitochondria by a specific antiporter in exchange for oxaloacetate (Li et al., 2011a,b). Itaconic acid – formed upon cis-aconitate decarboxylation – is finally secreted out of mycelia by a specific cell membrane transporter. Genes encoding these three enzymes, and a fourth one encoding a transcription factor, constitute the “itaconate gene cluster” in the A. terreus genome, while the cluster is notably absent in A. niger. Although several itaconate producers have been tested, the plant pathogenic Basidiomycete Ustilago maydis (the corn smut fungus) – and particularly its low pH-stable relative Ustilago cynodontis (Hosseinpour Tehrani et al., 2019b) – seems to be the only one with a reasonable chance to become another industrial platform organism (Hosseinpour Tehrani et al., 2019a). Ustilago has developed an alternative biochemical pathway to synthetize itaconate inasmuch as cis-aconitate is converted to the thermodynamically favored trans-aconitate by aconitate-delta-isomerase. Trans-aconitate is then decarboxylated to itaconate by trans-aconitate-decarboxylase. Production of Itaconic Acid by Fermentation Processes Itaconic acid is produced in batch fermentation in a process largely similar to that of citric acid. The carbon source should be in an easily metabolizable form (glucose syroup, molasses, and crude starch hydrolysates) and diluted to approximately 10% wt. Phosphate limitation is necessary for growth restriction. Some trace metals should also be in limited amounts and this is usually achieved by treating the media with hexacyanoferratl or addition of copper. The pH is kept between 2.8 and 3.2. Lower pH values favor the formation of byproducts. Yields of 50–60% of the theoretical yield are obtained in 8–10 days [5]. For many years, there seems to be almost no research interest for the production of itaconic acid and the process remained unchanged since its introduction. The situation is different today. Itaconic acid is listed by the US Department of Energy (DOE) as one of the 12 building blocks with the highest potential to be produced by industrial biotechnology [11]. Its current low production limits its uses. Metabolic engineering strategies, as an approach for yield improvement, have not yet been applied with A. terreus, as they were restricted by the poor knowledge of the genetics of itaconic acid biosynthesis. Recently, however, three genes – crucial in itaconic acid production by A. terreus – were identified by researchers in Toegepast Natuurwetenschappelijk Onderzoek (TNO), the Netherlands [15]. Apart from the new knowledge on the genetics of biosynthesis, the development of new fermentation technologies and more sophisticated bioprocess control has led to renewed interest in improving itaconic acid production. Novel fed-batch strategies and continuous processes using immobilized cultures are being developed and investigated. Itaconic acid is a dicarboxylic acid, which is used in industry as a precursor of polymers used in plastics, adhesives, and coatings. New uses of itaconic acid-derived polymers are under active investigation. The production of itaconic acid for 2001 was quoted as 15 000 tons. There is a renewed interest in this chemical as industry searches for substitutes of petroleum-derived chemicals. Virtually all itaconic acid produced is by fermentation by specific strains of A. terreus. Itaconic acid production is a further perversion of the Krebs cycle, citrate is converted as normally into cis-aconitate, which for reasons unknown is, in some organisms, decarboxylated into itaconitate, which has no known metabolic role in the cell. The fact that different strains of Aspergillus and more generally of fungi can divert metabolic pathways to the overproduction and secretion of useful chemicals, coupled with the fact that these organisms can grow on residues of processes such as sugar and ethanol production, open the possibility of engineering pathways to produce high value chemicals through ‘green’, low polluting, waste-eliminating procedures. Production Itaconic Acid Itaconic acid is an example of a di-carbonic unsaturated acid. These acids are used as building blocks for large numbers of compounds, such as resins, paints, plastics, and synthetic fibers (acrylic plastic, super absorbants, and antiscaling agents) [67]. The CAC intermediate cis-aconitate is enzymatically processed by cis-aconitate dehycarboxylase (CadA) to produce itaconic acid [68]. At the industrial scale the most explored organism for the fermentative production of itaconic acid is Aspergillus terrus. The biosynthetic pathway of itaconic acid is like citrate biosynthesis, where the flux of the CAC is used in the catalytic conversion of cis-aconitate into itaconic acid. Thus citrate is synthesized from oxaloacetate and acetyl CoA, while oxaloacetate is synthesized from pyruvate by anaplerosis, which starts from the pyruvate that is the end product of glycolysis (Fig. 13.17). Itaconic acid (methylenesuccinic acid, C5H6O4) (Figure 17) is a white colorless crystalline, hygroscopic powder soluble in water, ethanol, and acetone. It is an unsaturated diprotic acid, which derives its unique chemical properties from the conjugation of one of its two carboxylic acid groups with its methylene group. Itaconic acid was discovered by Baup in 1837 as a product of pyrolytic distillation of citric acid. The name itaconic was devised as an anagram of aconitic. Itaconic acid is formed in fermentation of some sugars. In 1929, Kinoshita first showed the acid to be a metabolic product of Aspergillus itaconicus. A derivative of itaconic acid (trans-phenylitaconic acid) was isolated from another natural source (Artemisia argyi). The biosynthetic pathway of itaconic acid from glucose is similar to that of citric acid, which occurs via the glycolytic pathway and anaplerotic formation of oxaloacetate by CO2 fixation and via the TCA cycle (Figure 2). Itaconic acid is formed by the cytosolic enzyme aconitate decarboxylase from cis-aconitic acid. Another biosynthetic pathway from pyruvate through citramalic acid, citraconic acid, and itartaric acid also results in itaconic acid (Figure 18). In contrast to several other organic acids (e.g., citric, isocitric, lactic, fumaric, and l-malic acid) itaconic acid is used exclusively in nonfood applications, especially in the polymer industry. Itaconic acid derivatives are used in medicine, cosmetics, lubricants, thickeners, and herbicides (e.g., substituted itaconic acid anilides). Itaconic acid is produced solely by batch submerged fungal fermentation. Aspergillus terreus has been used from the 1940s in the fermentation process, which is similar to that of citric acid (see ‘Citric acid’), that is, it requires an excess of readily metabolizable sugar (glucose syrup, crude starch hydrolysates, and decationized molasses – up to 200 g l−1 sugar), continuous aeration, a low initial pH (between 3 and 5), sufficient nitrogen, high magnesium sulfate concentration (0.5%), low phosphate to limit biomass production, and a limitation in metal ions (zinc, copper, and iron). However, there exists one significant difference in that the sensitivity of this fungus to the formed acid, in contrast to A. niger, necessitates maintaining of the pH at 2.8–3.1 throughout the fermentation, in order to obtain high amounts of the acid. At present, the published production yield of itaconic acid is about 85% of theoretical, accompanied by product concentrations of about 80 g l−1 during a cultivation at 39–42 °C for 8–10 days. Recovery of itaconic acid is accomplished by first separating the fungal biomass by filtration followed by evaporation, treatment with active carbon, and crystallization and recrystallization. Actual markets for itaconic acid are currently limited because the fungal fermentation is carried out at a relatively high cost. New biotechnological approaches, such as published immobilization techniques, screening programs for other producing organisms (such as yeast), and genetic engineering of A. terreus (the annotated genome sequence of A terreus strain NIH 2624 has been publicly released), or of A. niger, could lead to higher production of itaconic acid. Also, the use of alternative substrates may reduce costs and thus open the market for new and expanded applications of this acid. This valuable acid can be produced by several organisms, such as Candida sp., Pseudozyma antarctica, and several species of Aspergillus [49], but the two most common microorganisms used are Aspergillus terreus, used in industrial processes, and Ustilago maydis, which is currently being actively investigated as a possible industrial product. The acid is used commercially as a comonomer in some synthetic rubbers (styrene-butadiene and nitrilic) and as a plasticizer in the formulation of other polymers. Its production is traditionally done using sugars as raw materials, in a technology that was developed in the first half of the 20th century [50], but that was not developed due to the low competitivity of the acid with the petrochemical acrylic acid. With the development of integrated and sustainable processes, the interest in the bioproduction of itaconic acid is renewed. Itaconic acid, or methylidenesuccinic acid, is an organic compound. This dicarboxylic acid is a white solid that is soluble in water, ethanol, and acetone. Historically, itaconic acid was obtained by the distillation of citric acid, but currently it is produced by fermentation.

The generally accepted route for itaconate is via glycolysis, tricarboxylic acid cycle, and a decarboxylation of cis-aconitate to itaconate via cis-aconitate-decarboxylase. The smut fungus Ustilago maydis uses an alternative route. Cis-aconitate is converted to the thermodynamically favoured trans-aconitate via aconitate-Δ-isomerase (Adi1). trans-Aconitate is further decarboxylated to itaconate by trans-aconitate-decarboxylase (Tad1).

Dry distillation of citric acid affords itaconic anhydride, which undergoes hydrolysis to itaconic acid.

Steps in conversion of citric acid to citraconic acid via itaconic and aconitic acids. Partial hydrogenation of itaconic acid over Raney nickel affords 2-methylsuccinic acid. Itaconic acid is primarily used as a co-monomer in the production of acrylonitrile butadiene styrene and acrylate latexes with applications in the paper and architectural coating industry. Itaconic acid is produced using A. terreus, from simple sugars. The production can be done using submerged solid fermentation, and the typical substrates are derived from sugar production, such as molasses. The accepted mechanism for itaconic acid production consists of the conversion of cis-aconitate to itaconate by an enzymatically catalyzed decarboxylation [53] (Fig. 18.6). Cis-aconitate is part of the Krebs cycle, so that the process is aerobic—actually extremely oxygen dependent, as determined by Gyamerah [54]. Calcium and zinc are important [55], as well as copper [56], and the maintenance of a low phosphate level is essential [53]. The ideal temperature is 40°C, and pH must be reduced to 2 to start the production. The process is extremely aerobic for the first 72 h of the process, with yields around 60%w/w (product/substrate) [55]. The final concentration ranges between 30 and 60 g/L depending on the substrate [56–58]. After fermentation, the broth is clarified and the free acid can be concentrated and crystallized, but if a base is used for partial neutralization during the process (which can increase the yield), it is necessary to remove the cations used in the crystallization. The production of itaconic acid in SSF is still elusive: reports describe productions on the order of 5–40 g/kg dry substrate [59]. Some of the reports that describe higher yields, around 60%, actually use a support soaked with a nutritive solution [60,61]. A comparison between synthetic liquid and solid media showed that the process in SSF has a lower conversion (16%–23%) than that of the submerged process (around 60%). There is no definite explanation for the lower production in solid-state yet, but there seems to be an excess of phosphate or the lack of essential nutrients in most solid substrates tested for itaconic acid reduction. First obtained from the distillation of citric acid, since 1960 itaconic acid has been produced by fermentation of carbohydrates by A. terreus (Mitsuyasu et al., 2009; Hajian and Yusoff, 2015). Itaconic acid has been applied in a numerous range of industries with the larger producers in the world being the USA, Japan, Russia, and China (Global Industry Analysts Inc., 2011). During the 1950s, itaconic acid was used in industrial adhesives. In that period, itaconic acid was used at an industrial scale and large amounts of it were required. It has been employed as a detergent and in shampoos, as well as in plastics, elastomers, fiberglass, and in the coating process of carpets and book covers (Mitsuyasu et al., 2009; Jin et al., 2010). Besides that itaconic acid may also be used as artificial gems and synthetic glasses (Kin et al., 1998). Lately, the applications of the compound have reached the biomedical fields, such as the ophthalmic, dental and drug delivery fields (Hajian and Yusoff, 2015). Several studies have focused on improving and optimizing the production of itaconic acid from A. terreus in recent years. The biotechnological aspects involved in the metabolic pathways of itaconic acid and the production process parameters have been reviewed by Klement and Büchs (2013). Regarding the production, Amina et al. (2013) obtained itaconic acid using oil byproduct jatropha curcas seed cake, while Li et al. (2011), Huang et al. (2014), and van der Straat et al. (2014) studied the itaconic acid production by using genetic engineering techniques. In this process the relevant pathways have been revealed and new microbial production platforms designed, contributing to an enhanced production of itaconic acid. Furthermore, the reduction of its production costs is an important aspect for itaconic acid producers, either by optimizing processes or by using cost-favorable raw materials. Itaconic acid or methylene succinic acid is a high-value platform chemical that finds application in polymer industry, wastewater treatment, and ion-exchange chromatography sector (Willke and Vorlop, 2001). It can be converted to 3-methyltetrahydrofuran that has superior emission and combustion properties when compared to gasoline. Industrial production of itaconic acid is carried out with A. terreus using glucose as the sole carbon source. Itaconic acid production by metabolically engineered Neurospora crassa using lignocellulosic biomass was evaluated by Zhao et al. (2018). Cis-aconitic acid decarboxylase gene was heterologously expressed in N. crassa to synthesize itaconic acid. The engineered strain was capable of producing itaconic acid (20.41 mg/L) directly from lignocellulosic biomass. Itaconic acid production from biomass hydrolyzate using Aspergillus strains was reported by Jiménez-Quero et al. (2016). Acid and enzymatic hydrolyzates were evaluated for the production of itaconic acid. Maximum itaconic acid production (0.14%) was observed when submerged fermentation was carried out with corncob hydrolyzate by A. oryzae. The study reveals the possibility of SSF of biomass for the production of itaconic acid. Klement et al. (2012) evaluated itaconic acid production by Ustilago maydis from hemicellulosic fraction of pretreated beech wood. One of the advantages of U. maydis is that the strain grows as yeast-like single cells, and it can survive under high osmotic stress. The study revealed that under mild pretreatment conditions, U. maydis would be a promising candidate for itaconic acid production. Fine tuning of pretreatment conditions should be carried out for the improved production of itaconic acid. Production Itaconic Acid Itaconic acid is an example of a di-carbonic unsaturated acid. These acids are used as building blocks for large numbers of compounds, such as resins, paints, plastics, and synthetic fibers (acrylic plastic, super absorbants, and antiscaling agents) [67]. The CAC intermediate cis-aconitate is enzymatically processed by cis-aconitate dehycarboxylase (CadA) to produce itaconic acid [68]. At the industrial scale the most explored organism for the fermentative production of itaconic acid is Aspergillus terrus. The biosynthetic pathway of itaconic acid is like citrate biosynthesis, where the flux of the CAC is used in the catalytic conversion of cis-aconitate into itaconic acid. Thus citrate is synthesized from oxaloacetate and acetyl CoA, while oxaloacetate is synthesized from pyruvate by anaplerosis, which starts from the pyruvate that is the end product of glycolysis (Fig. 13.17) [69]. Itaconic acid (IA) can be used: • As a comonomer in the polymerization of polyacrylonitrile (PAN) to promote the thermo-oxidative stabilization of polymer.[1] • In combination with acrylamide to form (poly[acrylamide-co-(itaconicacid)]) to synthesize biodegradable superabsorbent polymers.[2] • To synthesize biobased polyester composite in fabric industry. Itaconic acid is an unsaturated dicarbonic acid which has a high potential as a biochemical building block, because it can be used as a monomer for the production of a plethora of products including resins, plastics, paints, and synthetic fibers. Some Aspergillus species, like A. itaconicus and A. terreus, show the ability to synthesize this organic acid and A. terreus can secrete significant amounts to the media (>80 g/L). However, compared with the citric acid production process (titers >200 g/L) the achieved titers are still low and the overall process is expensive because purified substrates are required for optimal productivity. Itaconate is formed by the enzymatic activity of a cis-aconitate decarboxylase (CadA) encoded by the cadA gene in A. terreus. Cloning of the cadA gene into the citric acid producing fungus A. niger showed that it is possible to produce itaconic acid also in a different host organism. This review will describe the current status and recent advances in the understanding of the molecular processes leading to the biotechnological production of itaconic acid. Itaconic acid (2-methylidenebutanedioic acid) is an unsaturated di-carbonic acid. It has a broad application spectrum in the industrial production of resins and is used as a building block for acrylic plastics, acrylate latexes, super-absorbents, and anti-scaling agents (Willke and Vorlop, 2001; Okabe et al., 2009). Since the 1960s the production of itaconic acid is achieved by the fermentation with Aspergillus terreus on sugar containing media (Willke and Vorlop, 2001). Although also other microorganisms like Ustilago zeae (Haskins et al., 1955), U. maydis, Candida sp. (Tabuchi et al., 1981), and Rhodotorula sp. (Kawamura et al., 1981) were found to produce itaconic acid, A. terreus is still the dominant production host, because so far only bred strains of this species can reach levels of up to 80–86 g/L (Okabe et al., 2009; Kuenz et al., 2012). Since the 1990s, itaconic acid as a renewable material is attracting a lot of interest. Currently, the worldwide production capacity of itaconic acid is expected to be about 50 kt per year, facing a demand of about 30 kt (Shaw, 2013, Itaconix Corporation, personal communication). Especially, for the production of polymers it is of interest, because in the future it can function as a substitute for acrylic and methacrylic acid used for the production of plastics (Okabe et al., 2009). However, these applications require an even lower price of the starting material. The current knowledge about the biotechnological production of itaconic acid was recently reviewed (Willke and Vorlop, 2001; Okabe et al., 2009). The latter review covers the industrial production of itaconic acid and the applications of this product. Therefore, we focus in this report on the recent advances with an emphasis on the biochemistry of the process and new genetic engineering targets. For rational strain improvement, it is essential to understand the underlying biological concepts and biochemical pathways leading to the production of this important organic acid in microorganisms. Biosynthesis Pathway Kinoshita (1932) recognized that a filamentous fungus was able to produce itaconic acid and consequently described this species as A. itaconicus. The biosynthesis of itaconic acid was for a long time hotly debated, because it was not clear whether itaconic acid arises from a pathway including parts of the tricarboxylic acid (TCA) cycle or an alternative pathway via citramalate or the condensation of acetyl-CoA. Bentley and Thiessen (1957a) proposed a pathway for the biosynthesis of itaconic acid, which is depicted in Figure 1. Starting from a sugar substrate like glucose the carbon molecules are processed via glycolysis to pyruvate. Then the pathway is split and part of the carbon is metabolized to Acetyl-CoA releasing a carbon dioxide molecule. The other part is converted to oxaloacetate so that the previously released carbon dioxide molecule is again incorporated. In the first steps of the citric acid cycle, citrate and cis-aconitate are formed. In the last step, the only itaconic acid pathway dedicated step, cis-aconitate decarboxylase (CadA) forms itaconic acid releasing carbon dioxide. This pathway was confirmed by tracer experiments with 14C and 13C labeled substrates (Bentley and Thiessen, 1957a; Winskill, 1983; Bonnarme et al., 1995) and also the necessary enzymatic activities have been all determined (Jaklitsch et al., 1991). The formation of carboxylic acids, like citric and itaconic acid, involves the shuttling of intermediate metabolites between different intracellular compartments and utilizes the different enzymatic capabilities of the respective compartment. In case of itaconic acid the compartmentalization of the pathway was analyzed by fractionized cell extracts distinguishing the enzymatic activity of a mitochondrial from a cytosolic enzyme. It was found that the key enzyme of the pathway, CadA, is not located in the mitochondria but in the cytosol (Jaklitsch et al., 1991), whereas the enzymes preceding in the pathway, namely citrate synthase and aconitase, are found in the mitochondria. However, a residual level of aconitase and citrate synthase activity is also found in the cytosolic fraction. The proposed mechanism is that cis-aconitate is transported via the malate–citrate antiporter into the cytosol (Jaklitsch et al., 1991). However, so far it was not shown whether cis-aconitate makes use of the mitochondrial malate–citrate antiporter or uses another mitochondrial carrier protein to be translocated to the cytosol. Besides A. terreus, itaconic acid is known to be produced also by other fungi like U. zeae (Haskins et al., 1955), U. maydis (Haskins et al., 1955; Klement et al., 2012), Candida sp. (Tabuchi et al., 1981), and Rhodotorula sp. (Kawamura et al., 1981). No further investigations exist about the underlying reaction principles leading to itaconic acid formation in those species. However, recent evidence (Strelko et al., 2011; Voll et al., 2012) points into the direction that CadA activity constitutes the general pathway toward the formation of itaconic acid in nature. Very recently, itaconic acid was detected in mammalian cells, where it was found in macrophage-derived cells (Strelko et al., 2011). Those cells also possess a CadA activity and have the ability to form itaconic acid de novo. But, up to now no specific gene encoding this enzymatic activity was identified in mammalian cells. However, the physiological role of itaconic acid in mammalian cells is still unknown. Strelko et al. (2011) speculate on the role of itaconic acid as an inhibitor of metabolic pathways, because it is described as an enzymatic inhibitor. On the one hand, itaconic acid is known to inhibit isocitrate lyase (Williams et al., 1971; McFadden and Purohit, 1977), which is the crucial part of the glyoxylate shunt, and thus can act as an antibacterial agent. On the other hand, itaconic acid can inhibit fructose-6-phosphate 2-kinase (Sakai et al., 2004) and thus have a direct influence on the central carbon metabolism. In rats it was shown that a itaconate diet leads to a reduced visceral fat accumulation, because of a suppressed glycolytic flux (Sakai et al., 2004). Itaconic Acid Pathway Specific Enzymes and Genes The reaction catalyzed by the cis-aconitic acid decarboxylase was already described in 1957 (Bentley and Thiessen, 1957a,b). Subsequently performed 13C and 14C labeling experiments (Winskill, 1983; Bonnarme et al., 1995) confirmed the reaction scheme depicted in Figure 2. Itaconic acid is formed by an allylic rearrangement and decarboxylation from cis-aconitic acid removing either carbon C1 or C5 from the starting citric acid molecule (because of the symmetry of the molecule). Catabolization of Itaconic Acid Much is known about the biosynthesis of itaconic acid and the underlying enzymatic mechanisms, but for a complete biochemical picture of a certain metabolite, also the knowledge about its degradation is necessary. Unfortunately, the information about the degradation pathway of itaconic acid is sc
