Le benzoate de benzyle (BnBzO) est un agent de médiation et un insectifuge. C'est l'une des préparations les plus anciennes utilisées pour traiter la gale, une infection cutanée causée par l'acarien Sarcoptes scabiei car elle est mortelle pour l'acarien. Il est capable de tuer l'acarien en 5 minutes. Il peut également être utilisé pour le traitement de l'infestation par les poux de la tête et du corps. Son mécanisme d'action consiste à exercer des effets toxiques sur le système nerveux des insectes, provoquant en outre sa mort. Il est également toxique pour les ovules d'acariens par un mécanisme inconnu. Il peut également être utilisé comme répulsif pour les aoûtats, les tiques et les moustiques, ainsi que comme support de colorant, solvant des dérivés de cellulose, plastifiant et fixateur.
Les usages
Médical
Le benzoate de benzyle est un traitement topique efficace et peu coûteux pour la gale humaine. Il a des effets vasodilatateurs et spasmolytiques et est présent dans de nombreux médicaments contre l'asthme et la coqueluche. Il est également utilisé comme excipient dans certains médicaments de remplacement de la testostérone (comme Nebido) pour traiter l'hypogonadisme.
Le benzoate de benzyle est utilisé comme acaricide topique, scabicide et pédiculicide dans les hôpitaux vétérinaires.
Non médical
Le benzoate de benzyle est utilisé comme répulsif pour les aoûtats, les tiques et les moustiques. Il est également utilisé comme support de colorant, solvant pour les dérivés de cellulose, plastifiant et fixateur dans l'industrie du parfum.
Chimie
C'est un composé organique de formule C6H5CH2O2CC6H5. C'est l'ester de l'alcool benzylique et de l'acide benzoïque. Il forme un liquide visqueux ou des flocons solides et dégage une faible odeur de balsamique sucré. Il se produit dans un certain nombre de fleurs (par exemple la tubéreuse) et est un composant du baume du Pérou et du baume de Tolu.
Production
Le benzoate de benzyle est produit industriellement par réaction du benzoate de sodium avec de l'alcool benzylique en présence d'une base, ou par transestérification du benzoate de méthyle et de l'alcool benzylique. C'est un sous-produit de la synthèse de l'acide benzoïque par oxydation du toluène. Il peut également être synthétisé par la réaction de Tishchenko, en utilisant du benzaldéhyde avec du benzilate de sodium (généré à partir de sodium et d'alcool benzylique) comme catalyseur:
La réaction de Tishchenko: le benzaldéhyde réagit au benzoate de benzyle, le catalyseur est le benzilate de sodium.
Il se produit naturellement dans les huiles essentielles telles que l'ylang-ylang, le bois de rose, la cannelle et le benjoin.
Lorsque ces huiles essentielles ne sont pas utilisées dans un produit, le benzoate de benzyle peut être ajouté sous sa forme synthétique en raison de son parfum incroyable et de ses excellentes propriétés de solvant. En effet, il dissout les autres matières parfumées, leur permettant de se fondre plus facilement.
Qu'est-ce que le benzoate de benzyle?
Le benzoate de benzyle est une molécule naturelle que l'on trouve dans certaines plantes et se compose d'alcool benzylique et d'acide benzoïque. Dans les produits cosmétiques, il joue un certain nombre de rôles en fonction du produit et il peut agir comme un parfum, un solvant, un plastifiant, un conservateur et un fixateur.
Comment ça marche?
En tant que parfum, le benzoate de benzyle peut ajouter une odeur balsamique à un produit. Il peut également fonctionner avec d'autres parfums comme solvant pour les aider à se dissoudre dans le mélange. Le benzoate de benzyle agit également comme fixateur dans les produits parfumés où il ralentit la fuite d'autres parfums et augmente la durée de vie du parfum.
Lorsqu'il est ajouté à des produits plus solides comme les savons, le benzoate de benzyle peut agir comme plastifiant. Un plastifiant rend un produit moins cassant, de sorte qu'un savon qui le contient peut être plié et écrasé davantage avant qu'il ne craque ou ne s'effrite.
Le benzoate de benzyle est utilisé pour traiter les infestations de poux et de gale. On pense que ce médicament est absorbé par les poux et les acariens et les détruit en agissant sur leur système nerveux.
Le benzoate de benzyle est l'une des préparations les plus anciennes utilisées pour traiter la gale. La gale est une infection cutanée causée par l'acarien Sarcoptes scabiei. Elle se caractérise par de fortes démangeaisons (en particulier la nuit), des taches rouges et peut conduire à une infection secondaire. Le benzoate de benzyle est mortel pour cet acarien et est donc utile dans le traitement de la gale. Il est également utilisé pour traiter les infestations de poux de la tête et du corps.
Mécanisme d'action
Le benzoate de benzyle exerce des effets toxiques sur le système nerveux du parasite, entraînant sa mort. Il est également toxique pour les ovules d'acariens, bien que son mécanisme d'action exact soit inconnu. In vitro, le benzoate de benzyle tue l'acarien Sarcoptes en 5 minutes.
Absorption
Aucune donnée n'est disponible sur l'absorption percutanée du benzoate de benzyle. Certaines études plus anciennes ont suggéré une certaine absorption percutanée, cependant, la quantité n'a pas été quantifiée.
Métabolisme
Rapidement hydrolysé en acide benzoïque et en alcool benzylique, qui est ensuite oxydé en acide benzoïque. L'acide benzoïque est conjugué à la glycine pour former de l'acide hippurique.
Le benzoate de benzyle est un composé benzylique qui peut être synthétisé en faisant réagir du chlorure de benzyle avec du benzoate de sodium en présence d'iodure de tétrabutylaramonium. Il serait le constituant clé des huiles essentielles isolées des feuilles et de l'écorce de tige de Cinnamomum zeylanicum.
Le benzoate de benzyle, un ester d'alcool benzylique et d'acide benzoïque, est largement utilisé comme fixateur de parfum, ingrédient de parfum et conservateur pour maintenir la puissance et la stabilité d'une variété de formulations cosmétiques. Il est également utilisé comme musc synthétique, acaricide pour traiter la gale et les poux de tête.
L'alcool benzylique est un alcool organique présent dans de nombreux fruits et thés. L'alcool benzylique a un groupe hydroxyle, tandis que le composé apparenté, l'acide benzoïque, a un groupe carboxyle. Le benzoate de sodium, le benzoate de calcium et le benzoate de potassium sont des sels d'acide benzoïque. Le benzoate de benzyle est un ester d'alcool benzylique et d'acide benzoïque.
L'alcool benzylique, l'acide benzoïque et ses sels et le benzoate de benzyle sont utilisés dans une grande variété de cosmétiques et de produits de soins personnels, y compris les produits pour bébés, les produits de bain, les savons et détergents, le maquillage des yeux, les fards à joues, les produits nettoyants, les produits de maquillage, ainsi que produits de soin des cheveux, des ongles et de la peau.

Allergènes de contact Le benzoate de benzyle est l'ester de l'alcool benzylique et de l'acide benzoïque. Il est contenu dans Myroxylon pereirae et Tolu balsam. Il est utilisé dans les préparations acaricides contre Sarcoptes scabiei ou comme pédiculicide. Le contact direct peut provoquer une irritation cutanée, mais rarement une dermatite de contact allergique.
Utilisation clinique
Le benzoate de benzyle est un ester naturel obtenu à partir du baume du Pérou et d'autres résines. Il est également préparé synthétiquement à partir d'alcool benzylique et de chlorure de benzoyle. L'ester est un liquide clair incolore avec une légère odeur aromatique. Il est insoluble dans l'eau mais soluble dans les solvants organiques.
Le benzoate de benzyle est un scabicide efficace lorsqu'il est appliqué localement. Le soulagement immédiat des démangeaisons résulte probablement d'un effet anesthésique local; cependant, un durcissement complet est fréquemment obtenu avec une seule application d'une émulsion à 25% de benzoate de benzyle dans l'acide oléique, stabilisée avec de la triéthanolamine. Cette préparation présente l'avantage supplémentaire d'être essentiellement inodore, non tachante et non irritante pour la peau. Il est appliqué localement sous forme de lotion sur tout le corps humidifié, à l'exception du visage.
Le benzoate de benzyle est un ester de benzoate obtenu par condensation formelle d'acide benzoïque avec de l'alcool benzylique. Il a été isolé des espèces végétales du genre Polyalthia.

PROPRIÉTÉS PHYSIQUES ET CHIMIQUES DU BENZOATE DE BENZYLE
• Le benzoate de benzyle est insoluble dans l'eau et le glycérol. Soluble dans l'éthanol, l'éther éthylique, l'acétone, le benzène, le méthanol, le chloroforme.
• Le benzoate de benzyle est stable dans les conditions de stockage recommandées.
• Le benzoate de benzyle, lorsqu'il est chauffé pour se décomposer, produit des fumées amères et irritantes.
• Il se présente sous la forme d'un liquide visqueux ou de flocons solides et a une faible odeur balsamique.
Le benzoate de benzyle a un poids moléculaire élevé, ce qui en fait un fixateur largement utilisé dans l'industrie des parfums fins. Il est utilisé dans les formulations pharmaceutiques topiques pour le traitement des poux et de la gale. De plus, le benzoate de benzyle de Kalama est apprécié pour sa compatibilité avec la cire de bougie, incorporant un parfum aux bougies fines tout en favorisant une combustion propre.
Le traitement de la gale est avec la perméthrine topique, le benzoate de benzyle, le malathion, à son ir ou ivermectine orale. Le patient doit appliquer une crème de perméthrine à 5% sur tout le corps, y compris le cuir chevelu, tous les plis, l'aine, le nombril, les organes génitaux externes et la peau sous les ongles, en le lavant après 12 heures. Chez les adultes atteints de gale classique, le traitement du visage est controversé, mais chez les bébés, la peau du visage doit également être traitée. Une deuxième application 7 jours après le traitement initial doit être prescrite et tous les membres affectés d'un ménage doivent être traités en même temps pour éviter les réinfestations cycliques. L'ivermectine orale est de plus en plus utilisée comme traitement de première intention. Les flambées graves nécessitent une deuxième dose d'ivermectine à 2 semaines d'intervalle (200 µg / kg de poids corporel). Un traitement de l'infection bactérienne secondaire et des antihistaminiques peuvent être nécessaires. Laver les vêtements et le linge à 60 ° C tuera tous les jeunes acariens femelles fécondés (une alternative est de les conserver dans un sac en plastique pendant 48 à 72 heures, car les acariens séparés de l'hôte humain meurent dans ce délai). Il est important d'expliquer que le prurit dure généralement plusieurs semaines après la guérison, ce qui peut être partiellement atténué par des antihistaminiques non sédatifs ou sédatifs.
Le benzoate de benzyle est utilisé comme insecticide pour tuer les acariens de la gale, les acariens et les tiques. Il est également utilisé comme plastifiant, fixateur dans les parfums, additif alimentaire et solvant. La dermatite est la principale réaction indésirable à son utilisation comme solution topique. À des concentrations élevées, il s'est avéré posséder des propriétés œstrogéniques et stimuler la croissance des cellules mammaires humaines.

Benzyl benzoate (BnBzO) is mediation and insect repellent. It is one of the older preparation used to treat scabies which is a skin infection caused by the mite Sarcoptes scabiei since it is lethal to the mite. It is capable of killing the mite in 5 minutes. It can also be used for the treatment of lice infestation of the head and the body. Its mechanism of action is through exerting a toxic effects on the nervous system of the insects, further causing its death. It is also toxic to mite ova through an unknown mechanism. It can also be used as a repellent for chiggers, ticks, and mosquitoes as well as a dye carrier, solvent of cellulose derivatives, plasticizer, and a fixative.
Uses
Medical
Benzyl benzoate is an effective and inexpensive topical treatment for human scabies. It has vasodilating and spasmolytic effects and is present in many asthma and whooping cough drugs. It is also used as an excipient in some testosterone-replacement medications (like Nebido) for treating hypogonadism.
Benzyl benzoate is used as a topical acaricide, scabicide, and pediculicide in veterinary hospitals.
Non-medical
Benzyl benzoate is used as a repellent for chiggers, ticks, and mosquitoes. It is also used as a dye carrier, solvent for cellulose derivatives, plasticizer, and fixative in the perfume industry.
Chemistry
It is an organic compound with the formula C6H5CH2O2CC6H5. It is the ester of benzyl alcohol and benzoic acid. It forms either a viscous liquid or solid flakes and has a weak, sweet-balsamic odor. It occurs in a number of blossoms (e. g. tuberose) and is a component of Balsam of Peru and Tolu balsam.
Production
Benzyl benzoate is produced industrially by the reaction of sodium benzoate with benzyl alcohol in the presence of a base, or by transesterification of methyl benzoate and benzyl alcohol. It is a byproduct of benzoic acid synthesis by toluene oxidation. It can also be synthesized by the Tishchenko reaction, using benzaldehyde with sodium benzilate (generated from sodium and benzyl alcohol) as a catalyst:
The Tishchenko reaction: benzaldehyde reacts to benzyl benzoate, the catalyst is sodium benzilate.
It occurs naturally in essential oils such as ylang-ylang, rosewood, cinnamon and benzoin.
When these essential oils are not used in a product, Benzyl Benzoate can be added in its synthetic form because of its amazing scent and excellent solvent properties. Indeed, it dissolves other perfume materials, allowing them to blend more easily.
What is Benzyl Benzoate?
Benzyl benzoate is a naturally occurring molecule found in some plants and is made up of benzyl alcohol and benzoic acid. In cosmetic products, it plays a number of roles depending on the product and it can act as a fragrance, a solvent, a plasticizer, a preservative, and a fixative.
How does it work?
As a fragrance, benzyl benzoate can add a balsamic smell to a product. It can also work with other fragrances as a solvent to help them dissolve into the mixture. Benzyl benzoate also acts as a fixative in perfumed products where it slows down the escape of other fragrances and increases the life span of the fragrance.
When added to more solid products like soaps, benzyl benzoate can act as a plasticizer. A plasticizer makes a product less brittle so a soap containing it can be bent and squished more before it snaps or crumbles.
Benzyl benzoate is used to treat lice and scabies infestations. This medicine is believed to be absorbed by the lice and mites and to destroy them by acting on their nervous system.
Benzyl benzoate is one of the older preparations used to treat scabies. Scabies is a skin infection caused by the mite Sarcoptes scabiei. It is characterized by severe itching (particularly at night), red spots, and may lead to a secondary infection. Benzyl benzoate is lethal to this mite and so is useful in the treatment of scabies. It is also used to treat lice infestation of the head and body.
Mechanism of action
Benzyl benzoate exerts toxic effects on the nervous system of the parasite, resulting in its death. It is also toxic to mite ova, though its exact mechanism of action is unknown. In vitro, benzyl benzoate has been found to kill the Sarcoptes mite within 5 minutes.
Absorption
No data are available on the percutaneous absorption of benzyl benzoate. Some older studies have suggested some percutaneous absorption, however, the amount was not quantified.
Metabolism
Rapidly hydrolyzed to benzoic acid and benzyl alcohol, which is further oxidized to benzoic acid. The benzoic acid is conjugated with glycine to form hippuric acid.
Benzyl benzoate is a benzyl compound that can be synthesized by reacting benzyl chloride with sodium benzoate in the presence of tetrabutylaramonium iodide. It is reported to be the key constituent in the essential oils isolated from leaves and stem bark of Cinnamomum zeylanicum.
Benzyl benzoate, an ester of benzyl alcohol and benzoic acid, is widely used as a fragrance fixer, fragrance ingredient and preservative to maintain the potency and stability of a variety of cosmetic formulations. It is also employed as a synthetic musk, acaricide to treat scabies and headlice.

BENZYL BENZOATE PHYSICAL AND CHEMICAL PROPERTIES
• Benzyl Benzoate is insoluble in water and glycerol. Soluble in ethanol, ethyl ether, acetone, benzene, methanol, chloroform.
• Benzyl Benzoate is stable under recommended storage conditions.
• Benzyl Benzoate, when heated to decompose, produces bitter and irritating fumes.
• It is in the form of a viscous liquid or solid flakes and has a weak balsamic odor.
Benzyl Benzoate has a high molecular weight, making it an extensively used fixative in the fine fragrance and perfume industry. It is used in topical pharmaceutical formulations for the treatment of lice and scabies. Additionally, Kalama Benzyl Benzoate is valued for its compatibility with candlewax, incorporating fragrance to fine candles while also promoting clean burning.
Treatment of scabies is with topical permethrin, benzyl benzoate, malathion,to its ir or oral ivermectin. The patient should apply 5% permethrin cream to the whole body, including the scalp, all folds, groin, navel, external genitalia, and skin under the nails, washing it off after 12 hours. In adults with classical scabies, treatment of the face is controversial, but in babies, the skin of the face should also be treated. A second application 7 days after the original treatment must be prescribed and all the affected members of a household require treatment at the same time to prevent cyclical reinfestations. Oral ivermectin is being increasingly used as a first-line treatment. Severe outbreaks require a second dose of ivermectin at a 2-week interval (200 µg/kg body weight). Treatment of secondary bacterial infection and antihistamines may be required. Washing clothes and linen at 60° C will kill all the young fecundated female mites (an alternative is to keep these in a plastic bag for 48-72 hours, as mites separated from the human host die within this time). It is important to explain that pruritus commonly lasts for several weeks after cure, which may be partially alleviated by non-sedating or sedating antihistamines.
Benzyl benzoate is used as an insecticide to kill scabies mites, dust mites, and ticks. It is also used as a plasticizer, a fixative in fragrances, a food additive, and a solvent. Dermatitis is the primary adverse reaction to its use as a topical solution. At high concentrations, it has been found to possess estrogenic properties and to stimulate the growth of human breast cells.

Solubility: Benzyl benzoate is insoluble in water but soluble in organic solvents. Benzyl benzoate itself, a high-temperature solvent, is the only solvent of Musk. Benzyl benzoate has applications in the pharmacy and perfume industry just because of its characters of low volatilization and relative stability.
Applications:
Benzyl benzoate is mainly used in the area of textile auxiliary, fragrance and flavour, pharmacy, plasticizer and so on. Benzyl benzoate can be used as to lead agent, levelling agent and repair agent of textile auxiliaries. Mechanism: With the development of the textile industry, the materials are of a higher grade. The higher-grade cloth is, the more compact fabric is. So in dyeing, there are more difficulties in colouring and uniformity Due to the good plasticity performance, benzyl benzoate makes the fiber swell and undraw so that the fibre will be dyed easily. At the same time, benzyl benzoate is a good solvent to dissolve and disperse dye evenly. Since its quite good dye migration performance, benzyl benzoate could be developed as levelling agents and lead agents. There are many other materials, which have similar properties to benzyl benzoate, such as methylnaphthalene, dimethylnaphthalene, methyl salicylate, and benzene ester.
Benzyl benzoate is an organic compound that is used as a medication and insect repellent. As a medication, it is used to treat scabies and lice. For scabies either permethrin or malathion is typically preferred. It is applied to the skin as a lotion. Typically two to three applications are needed. It is also present in Balsam of Peru, Tolu balsam, and in a number of flowers. Benzyl benzoate was first studied medically in 1918. It is on the World Health Organization's List of Essential Medicines.

Benzyl benzoate (BnBzO) is mediation and insect repellent. It is one of the older preparation used to treat scabies which is a skin infection caused by the mite Sarcoptes scabiei since it is lethal to the mite. It is capable of killing the mite in 5 minutes. It can also be used for the treatment of lice infestation of the head and the body. Its mechanism of action is through exerting a toxic effects on the nervous system of the insects, further causing its death. It is also toxic to mite ova through an unknown mechanism. It can also be used as a repellent for chiggers, ticks, and mosquitoes as well as a dye carrier, solvent of cellulose derivatives, plasticizer, and a fixative.
Uses
Medical
Benzyl benzoate is an effective and inexpensive topical treatment for human scabies. It has vasodilating and spasmolytic effects and is present in many asthma and whooping cough drugs. It is also used as an excipient in some testosterone-replacement medications (like Nebido) for treating hypogonadism.
Benzyl benzoate is used as a topical acaricide, scabicide, and pediculicide in veterinary hospitals.
Non-medical
Benzyl benzoate is used as a repellent for chiggers, ticks, and mosquitoes. It is also used as a dye carrier, solvent for cellulose derivatives, plasticizer, and fixative in the perfume industry.
Chemistry
It is an organic compound with the formula C6H5CH2O2CC6H5. It is the ester of benzyl alcohol and benzoic acid. It forms either a viscous liquid or solid flakes and has a weak, sweet-balsamic odor. It occurs in a number of blossoms (e. g. tuberose) and is a component of Balsam of Peru and Tolu balsam.
Production
Benzyl benzoate is produced industrially by the reaction of sodium benzoate with benzyl alcohol in the presence of a base, or by transesterification of methyl benzoate and benzyl alcohol. It is a byproduct of benzoic acid synthesis by toluene oxidation. It can also be synthesized by the Tishchenko reaction, using benzaldehyde with sodium benzilate (generated from sodium and benzyl alcohol) as a catalyst:
The Tishchenko reaction: benzaldehyde reacts to benzyl benzoate, the catalyst is sodium benzilate.
It occurs naturally in essential oils such as ylang-ylang, rosewood, cinnamon and benzoin.
When these essential oils are not used in a product, Benzyl Benzoate can be added in its synthetic form because of its amazing scent and excellent solvent properties. Indeed, it dissolves other perfume materials, allowing them to blend more easily.
What is Benzyl Benzoate?
Benzyl benzoate is a naturally occurring molecule found in some plants and is made up of benzyl alcohol and benzoic acid. In cosmetic products, it plays a number of roles depending on the product and it can act as a fragrance, a solvent, a plasticizer, a preservative, and a fixative.
How does it work?
As a fragrance, benzyl benzoate can add a balsamic smell to a product. It can also work with other fragrances as a solvent to help them dissolve into the mixture. Benzyl benzoate also acts as a fixative in perfumed products where it slows down the escape of other fragrances and increases the life span of the fragrance.
When added to more solid products like soaps, benzyl benzoate can act as a plasticizer. A plasticizer makes a product less brittle so a soap containing it can be bent and squished more before it snaps or crumbles.
Benzyl benzoate is used to treat lice and scabies infestations. This medicine is believed to be absorbed by the lice and mites and to destroy them by acting on their nervous system.
Benzyl benzoate is one of the older preparations used to treat scabies. Scabies is a skin infection caused by the mite Sarcoptes scabiei. It is characterized by severe itching (particularly at night), red spots, and may lead to a secondary infection. Benzyl benzoate is lethal to this mite and so is useful in the treatment of scabies. It is also used to treat lice infestation of the head and body.
Mechanism of action
Benzyl benzoate exerts toxic effects on the nervous system of the parasite, resulting in its death. It is also toxic to mite ova, though its exact mechanism of action is unknown. In vitro, benzyl benzoate has been found to kill the Sarcoptes mite within 5 minutes.
Absorption
No data are available on the percutaneous absorption of benzyl benzoate. Some older studies have suggested some percutaneous absorption, however, the amount was not quantified.
Metabolism
Rapidly hydrolyzed to benzoic acid and benzyl alcohol, which is further oxidized to benzoic acid. The benzoic acid is conjugated with glycine to form hippuric acid.
Benzyl benzoate is a benzyl compound that can be synthesized by reacting benzyl chloride with sodium benzoate in the presence of tetrabutylaramonium iodide. It is reported to be the key constituent in the essential oils isolated from leaves and stem bark of Cinnamomum zeylanicum.
Benzyl benzoate, an ester of benzyl alcohol and benzoic acid, is widely used as a fragrance fixer, fragrance ingredient and preservative to maintain the potency and stability of a variety of cosmetic formulations. It is also employed as a synthetic musk, acaricide to treat scabies and headlice.

HOW BENZYL BENZOATE IS PRODUCED
Benzyl Benzoate is a naturally occurring molecule found in some plants (plant species of the genus Polyalthia) and consists of benzyl alcohol and benzoic acid. Benzyl benzoate was first studied medically in 1918.
It is a Benzoate ester obtained by formal condensation of Benzoic acid with Benzyl Alcohol. It can also be produced by the Tishchenko reaction, using benzaldehyde with sodium benzylate (produced from sodium and benzyl alcohol) as a catalyst.
BENZYL BENZOATE PHYSICAL AND CHEMICAL PROPERTIES
• Benzyl Benzoate is insoluble in water and glycerol. Soluble in ethanol, ethyl ether, acetone, benzene, methanol, chloroform.
• Benzyl Benzoate is stable under recommended storage conditions.
• Benzyl Benzoate, when heated to decompose, produces bitter and irritating fumes.
• It is in the form of a viscous liquid or solid flakes and has a weak balsamic odor.
Benzyl Benzoate has a high molecular weight, making it an extensively used fixative in the fine fragrance and perfume industry. It is used in topical pharmaceutical formulations for the treatment of lice and scabies. Additionally, Kalama Benzyl Benzoate is valued for its compatibility with candlewax, incorporating fragrance to fine candles while also promoting clean burning.
Treatment of scabies is with topical permethrin, benzyl benzoate, malathion,to its ir or oral ivermectin. The patient should apply 5% permethrin cream to the whole body, including the scalp, all folds, groin, navel, external genitalia, and skin under the nails, washing it off after 12 hours. In adults with classical scabies, treatment of the face is controversial, but in babies, the skin of the face should also be treated. A second application 7 days after the original treatment must be prescribed and all the affected members of a household require treatment at the same time to prevent cyclical reinfestations. Oral ivermectin is being increasingly used as a first-line treatment. Severe outbreaks require a second dose of ivermectin at a 2-week interval (200 µg/kg body weight). Treatment of secondary bacterial infection and antihistamines may be required. Washing clothes and linen at 60° C will kill all the young fecundated female mites (an alternative is to keep these in a plastic bag for 48-72 hours, as mites separated from the human host die within this time). It is important to explain that pruritus commonly lasts for several weeks after cure, which may be partially alleviated by non-sedating or sedating antihistamines.
Benzyl benzoate is used as an insecticide to kill scabies mites, dust mites, and ticks. It is also used as a plasticizer, a fixative in fragrances, a food additive, and a solvent. Dermatitis is the primary adverse reaction to its use as a topical solution. At high concentrations, it has been found to possess estrogenic properties and to stimulate the growth of human breast cells.

Since its quite good dye migration performance, benzyl benzoate could be developed as levelling agents and lead agents. There are many other materials, which have similar properties to benzyl benzoate, such as methylnaphthalene, dimethylnaphthalene, methyl salicylate, and benzene ester.
