Dibenzoyl peroxideis also used in dentistry for teeth whitening.
Dibenzoyl peroxide is also used in the plastics industry and for bleaching flour, hair, and textiles.

History of Dibenzoyl peroxide:
Dibenzoyl peroxide was first prepared and described by Liebig in 1858.
Dibenzoyl peroxidewas the first organic peroxide prepared intentionally.

Medical uses of Dibenzoyl peroxide:
Dibenzoyl peroxide is effective for treating acne lesions.
Dibenzoyl peroxidedoes not induce antibiotic resistance.
Dibenzoyl peroxidemay be combined with salicylic acid, sulfur, erythromycin or clindamycin (antibiotics), or adapalene (a synthetic retinoid).
Two common combination drugs include Dibenzoyl peroxide/clindamycin and adapalene/Dibenzoyl peroxide, an unusual formulation considering most retinoids are deactivated by peroxides.
Combination products such as Dibenzoyl peroxide/clindamycin and Dibenzoyl peroxide/salicylic acid appear to be slightly more effective than Dibenzoyl peroxide alone for the treatment of acne lesions.
The combination tretinoin/Dibenzoyl peroxide was approved in 2021.

Dibenzoyl peroxide for acne treatment is typically applied to the affected areas in gel, cream, or liquid, in concentrations of 2.5% increasing through 5.0%, and up to 10%.
No strong evidence supports the idea that higher concentrations of Dibenzoyl peroxide are more effective than lower concentrations.

Mechanism of action:
Classically, Dibenzoyl peroxide is thought to have a three-fold activity in treating acne.
Dibenzoyl peroxideis sebostatic, comedolytic, and inhibits growth of Cutibacterium acnes, the main bacterium associated with acne.
In general, acne vulgaris is a hormone-mediated inflammation of sebaceous glands and hair follicles.
Hormone changes cause an increase in keratin and sebum production, leading to blocked drainage. C. acnes has many lytic enzymes that break down the proteins and lipids in the sebum, leading to an inflammatory response.
The free-radical reaction of Dibenzoyl peroxide can break down the keratin, therefore unblocking the drainage of sebum (comedolytic).
Dibenzoyl peroxidecan cause nonspecific peroxidation of C. acnes, making Dibenzoyl peroxidebactericidal, and Dibenzoyl peroxidewas thought to decrease sebum production, but disagreement exists within the literature on this.
Some evidence suggests that Dibenzoyl peroxide has an anti-inflammatory effect as well. In micromolar concentrations Dibenzoyl peroxideprevents neutrophils from releasing reactive oxygen species, part of the inflammatory response in acne.

Other medical uses of Dibenzoyl peroxide:
Dibenzoyl peroxide is used in dentistry as a tooth whitening product.

Non-medical uses of Dibenzoyl peroxide:
Dibenzoyl peroxide is one of the most important organic peroxides in terms of applications and the scale of its production.
Dibenzoyl peroxideis often used as a convenient oxidant in organic chemistry.

Bleaching of Dibenzoyl peroxide:
Like most peroxides, Dibenzoyl peroxideis a powerful bleaching agent.
Dibenzoyl peroxidehas been used for the bleaching of flour, fats, oils, waxes, and cheeses, as well as a stain remover.

Polymerization of Dibenzoyl peroxide:
Dibenzoyl peroxide is also used as a radical initiator to induce chain-growth polymerization reactions, such as for polyester and poly(methyl methacrylate) (PMMA) resins and dental cements and restoratives.
Dibenzoyl peroxideis the most important among the various organic peroxides used for this purpose, a relatively safe alternative to the much more hazardous methyl ethyl ketone peroxide.
Dibenzoyl peroxideis also used in rubber curing and as a finishing agent for some acetate yarns.

Reactivity of Dibenzoyl peroxide:
The original 1858 synthesis by Liebig reacted benzoyl chloride with barium peroxide, a reaction that probably follows this equation:
2 C6H5C(O)Cl + BaO2 → (C6H5CO)2O2 + BaCl2

Dibenzoyl peroxide is usually prepared by treating hydrogen peroxide with benzoyl chloride under alkaline conditions.
2 C6H5COCl + H2O2 + 2 NaOH → (C6H5CO)2O2 + 2 NaCl + 2 H2O

The oxygen–oxygen bond in peroxides is weak.
Thus, Dibenzoyl peroxide readily undergoes homolysis (symmetrical fission), forming free radicals:
(C6H5CO)2O2 → 2 C6H5CO•2

The symbol • indicates that the products are radicals; i.e., they contain at least one unpaired electron.
Such species are highly reactive.
The homolysis is usually induced by heating.
The half-life of Dibenzoyl peroxide is one hour at 92 °C.
At 131 °C, the half-life is one minute.

Although the precise cause of acne is unclear, Dibenzoyl peroxide appears to be associated with at least four factors: increased sebum production, follicular keratinization, bacterial colonization, and inflammation.
The study suggests the prevalent bacterium implicated in the clinical course of acne is Propionibacterium acnes (P acnes), a gram-positive anaerobe that normally inhabits the skin and is implicated in the inflammatory phase of acne.
Dibenzoyl peroxide is mainly indicated in the treatment of mild to moderate acne and is often prescribed in conjunction with oral antibiotics (erythromycin or clindamycin) in the treatment of moderate to severe acne.

Dibenzoyl peroxide used in 2.5, 5, and 10 percent concentrations, depending on the acne severity.
Usually, these are in a gel spreading agent, but they can also be in a cream base or a drying paste.
Dibenzoyl peroxide is keratolytic, which means “keratin-dissolving” and works by loosening dead cells stuck in the follicles.
Dibenzoyl peroxide also releases oxygen in the follicle.
Because acne bacteria are anaerobic, they cannot survive in the presence of oxygen.
Dibenzoyl peroxide essentially works both as an interfollicular exfoliant and as an antibacterial.

Mode of action:
Dibenzoyl peroxide is lipophilic that can penetrate the stratum corneum and enter the pilosebaceous follicle.
Dibenzoyl peroxide is rapidly broken down to benzoic acid and hydrogen peroxide and generates free radicals that oxidize proteins in bacterial cell membranes, exerting a bactericidal action.
In addition, it has been shown that Dibenzoyl peroxide can reduce the free fatty acid content of sebum, which provides a useful marker for bacterial activity.
Dibenzoyl peroxide has an anti-inflammatory action and vitro studies suggest that this action arises from its ability to kill polymorphonuclear leukocytes (PMN cells) in the pilosebaceous follicles and so prevent their release of reactive oxygen species such as peroxides which enhance tissue inflammation.

Involving equation about this process:
C6H5C(O)O-OC(O)C6H5 + H2O 2 C6H5COOH + ½ O2
Moreover, due to its irritant effect, Dibenzoyl peroxide increases the turnover rate of epithelial cells, thereby peeling the skin and promoting the resolution of comedones.

Dibenzoyl peroxide is used as a bleaching agent for certain foods, an oxidizing agent, a polymerizing initiator in the manufacture of plastics, a curing agent for silicone rubber, and an ingredient in various industrial processes.
Dibenzoyl peroxide, like most peroxides, is a powerful bleaching agent.
Dibenzoyl peroxide has a long history of use in the food industry as a bleaching agent added for flour, whey, and milk for cheese making.

Contact with fabrics or hair can cause permanent color dampening almost immediately.
Even secondary contact can cause bleaching.
Dibenzoyl peroxide is widely used as a catalyst in the polymerisation of molecules like styrene (phenylethene) to form polystyrene, which used to make many things from drinking cups to packaging material.

Dibenzoyl peroxide and Pregnancy :
There are no studies looking at women who use topical Dibenzoyl peroxide during pregnancy.
When Dibenzoyl peroxide is applied topically, only 5% is absorbed through the skin, and then it is completely metabolized to benzoic acid within the skin and excreted unchanged in the urine.
Dibenzoyl peroxide is not likely to increase risk for birth defects or cause problems for the baby.
However, systemic effects on a pregnant woman and her child would not be expected and therefore use of this product during pregnancy would not be of concern.

Description of Dibenzoyl peroxide:
Dibenzoyl peroxide may affect workers in the electronics and plastics (epoxy resins and catalysts) industries, electricians, ceramic workers, dentists and dental technicians, laboratory technicians and bakers.
As it was contained in candles, Dibenzoyl peroxide also induced contact dermatitis in a sacristan.
However, some positive tests are of unknown occupational relevance.

Chemical Properties of Dibenzoyl peroxide:
Dibenzoyl peroxide is an odorless, white or colorless crystalline powder.

Uses of Dibenzoyl peroxide:
Dibenzoyl peroxide is an antibacterial ingredient commonly used in acne treatments.
Dibenzoyl peroxide functions by forcing an oxidant (peroxide in this case) into the philosebaceous orifice where it releases oxygen, thereby diminishing the P. acnes population.
This reduces the level of free fatty acids and skin infection.

Source of free radicals for industrial processes.
Oxidizing agent in bleaching oils, flour, etc.; catalyst in the plastics industry; initiator in polymerization.
Dibenzoyl peroxide is used as a source offree radicals in many organic syntheses andto initiate polymerizations of styrene, vinylchloride, vinyl acetate, and acrylics; to curethermoset polyester resins and silicone rubbers;in medicine for treating acne; and forbleaching vegetable oil, cheese, flour, and fats.

Indications of Dibenzoyl peroxide:
Dibenzoyl peroxide is a potent oxidizing agent that has both antimicrobial and comedolytic properties; its primary use is in treating acne vulgaris.
Dibenzoyl peroxide is converted in the skin to benzoic acid; clearance of absorbed drug is rapid, and no systemic toxicity has been observed.
The major toxicities are irritation and contact allergy.
Outgrowth of bacteria resistant to topical antibiotics used to treat acne can be reduced by the addition of Dibenzoyl peroxide in combination products such as erythromycin (Benzamycin) and clindamycin (Benzaclin).

Veterinary Drugs and Treatments:
Dibenzoyl peroxide products are used topically either as gels or in shampoos.
Shampoos are generally used for seborrheas, greasy skin (seborrhea oleosa), or crusty pyodermas (such as seborrheic dermatitis/pyoderma commonly seen in Cocker Spaniels).
Gels may be useful for treating recurrent localized skin infections (e.g., chin acne), localized Demodex lesions, superficial and deep pyodermas (adjunctive therapy), seborrhea oleosa, and Schnauzer comedo syndrome.

Dibenzoyl peroxide possesses antimicrobial (especially antibacterial), keratolytic and antiseborrheic actions.
Dibenzoyl peroxide also is Dibenzoyl peroxide has some mild antipruritic activity and wound healing effects, and is thought to increase follicular flushing.
Dibenzoyl peroxide’s antimicrobial activity is due to the oxidative benzoyl peroxy radicals formed that disrupt cell membranes.

Uses of Dibenzoyl peroxide:
-Various types of paint for various uses
-Plastic products, industry for plastics, manufacturing of plastics, plastic additives
-Rubber products (e.g. tires) and their manufacture
-Relatived to the maintenance and repair of automobiles, products for cleaning and caring for automobiles (auto shampoo, polish/wax, undercarriage treatment, brake grease)

Dibenzoyl peroxide has also been crystallised from 50% MeOH and from diethyl ether.

How to use Dibenzoyl peroxide?
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack.
Dibenzoyl peroxide will give you more information about Dibenzoyl peroxide and will provide you with a full list of the side-effects which you could experience from using it.
Dibenzoyl peroxide is recommended that you use Dibenzoyl peroxide once or twice each day.

When you first start using it, you will be recommended to use a 4% or 5% strength preparation.
This will help keep any skin irritation to a minimum.
If you find Dibenzoyl peroxide does irritate then try the 2.5% strength once the irritation has settled.
These strength preparations often work as well as the higher 10% strength preparations and cause less skin irritation.
If necessary, you can increase the strength of the preparation as you go on, but do this gradually.

A general point is that you should apply Dibenzoyl peroxide to all of the area where your spots occur and not just to each spot.
Creams and gels should be applied about 15 minutes or so after washing the area with soap and water and gently drying with a towel.
At first you may want to wash the preparation off after a few hours, but gradually try to increase the length of time you leave it on the skin.
When your skin is used to the preparation, aim to put it on twice a day and leave it on.
If you are using a 'wash', wet your skin and then pour some of the liquid wash on to your hands and use it to wash the affected areas.
Leave Dibenzoyl peroxide on for a minute or so before you rinse it off.

Can Dibenzoyl peroxide cause problems?
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.
The table below contains some of the most common ones associated with preparations containing Dibenzoyl peroxide.
You will find a full list in the manufacturer's information leaflet supplied with your medicine.
The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

Dibenzoyl peroxide is used to treat mild to moderate acne.

Dibenzoyl peroxide is used, in particular, for external treatment of acne.
About 5% is absorbed (Leachman 2006).
To some extent, Dibenzoyl peroxide is converted to benzoic acid in the skin.

Simultaneous topical therapy with retinoids increases the absorption.
Dibenzoyl peroxide is also used in the food and plastics industries.
There are insufficient epidemiological data for a risk assessment.
Despite the broad use, there are no indications of any teratogenic effects.

Most people with acne are aged between 12 and 25, but some older and younger people are affected too.
Small sebaceous glands lie just under your skin surface and make an oil (sebum) that keeps your skin supple and smooth.
Tiny pores on your skin allow the sebum to come on to the surface of your skin.
In acne, some of these pores become blocked, causing small pimples, blackheads and whiteheads.

Dibenzoyl peroxide has three actions - it kills germs (bacteria), it reduces inflammation and it helps to unplug blocked pores.
You can buy Dibenzoyl peroxide without a prescription at a pharmacy.
Dibenzoyl peroxide comes in different brand names and strengths - there is a 2.5%, 4%, 5% and 10% strength.

Dibenzoyl peroxide is also available in combination preparations used for acne.
Dibenzoyl peroxide can be combined with an antibiotic called clindamycin, or with another medicine used for acne, called adapalene (brand name Epiduo®).
Both of these preparations need to be prescribed by a doctor, and should be used as directed by the doctor.

Before using Dibenzoyl peroxide:
To make sure that this is the right treatment for you, before you start using Dibenzoyl peroxide it is important that your doctor or pharmacist knows:

If you are pregnant or breastfeeding, although Dibenzoyl peroxide is not known to be harmful in pregnancy.
If you are taking any medicines, or using any other skin preparations.
This includes any which are available to buy without a prescription, as well as herbal and complementary medicines.
If you have ever had an allergic reaction to a skin product.

STRUCTURE AND REACTIVITY OF DIBENZOYL PEROXIDE (BENZOYL PEROXIDE)
Structure of Dibenzoyl Peroxide (Benzoyl Peroxide) from X-ray crystallography.
The O=C-O-O dihedral angle is 90°.
The O-O distance is 1.434 Å.

The original 1858 synthesis by Liebig reacted benzoyl chloride with barium peroxide,[15] a reaction that probably follows this equation:
2 C6H5C(O)Cl + BaO2 → (C6H5CO)2O2 + BaCl2
Dibenzoyl Peroxide (Benzoyl Peroxide) is usually prepared by treating hydrogen peroxide with benzoyl chloride under alkaline conditions.
2 C6H5COCl + H2O2 + 2 NaOH → (C6H5CO)2O2 + 2 NaCl + 2 H2O

The oxygen–oxygen bond in peroxides is weak.
Thus, Dibenzoyl Peroxide (Benzoyl Peroxide) readily undergoes homolysis (symmetrical fission), forming free radicals:
(C6H5CO)2O2 → 2 C6H5CO•2
The symbol • indicates that the products are radicals; i.e., they contain at least one unpaired electron.
Such species are highly reactive.

The homolysis is usually induced by heating.
The half-life of Dibenzoyl Peroxide (Benzoyl Peroxide) is one hour at 92 °C. At 131 °C, the half-life is one minute.


In 1901, J. H. Kastle and his graduate student A. S. Loevenhart observed that the compound made the tincture of guaiacum tincture turn blue, a sign of oxygen being released.
Around 1905, Loevenhart reported on the successful use of Dibenzoyl Peroxide (Benzoyl Peroxide) to treat various skin conditions, including burns, chronic varicose leg tumors, and tinea sycosis.
He also reported animal experiments that showed the relatively low toxicity of the compound.


Treatment with Dibenzoyl Peroxide (Benzoyl Peroxide) was proposed for wounds by Lyon and Reynolds in 1929, and for sycosis vulgaris and acne varioliformis by Peck and Chagrin in 1934.
However, preparations were often of questionable quality.
It was officially approved for the treatment of acne in the US in 1960.

Polymerization:
Dibenzoyl Peroxide (Benzoyl Peroxide) is mainly used as a radical initiator to induce chain-growth polymerization reactions,[4] such as for polyester and poly(methyl methacrylate) (PMMA) resins and dental cements and restoratives.
Dibenzoyl Peroxide (Benzoyl Peroxide) is the most important among the various organic peroxides used for this purpose, a relatively safe alternative to the much more hazardous methyl ethyl ketone peroxide.
Dibenzoyl Peroxide (Benzoyl Peroxide) is also used in rubber curing and as a finishing agent for some acetate yarns.

USES OF DIBENZOYL PEROXIDE (BENZOYL PEROXIDE):
Tube of a water-based 5% Dibenzoyl Peroxide (Benzoyl Peroxide) preparation for the treatment of acne
Dibenzoyl Peroxide (Benzoyl Peroxide) is effective for treating acne lesions.
Dibenzoyl Peroxide (Benzoyl Peroxide) does not induce antibiotic resistance.

Dibenzoyl Peroxide (Benzoyl Peroxide) may be combined with salicylic acid, sulfur, erythromycin or clindamycin (antibiotics), or adapalene (a synthetic retinoid).
Two common combination drugs include Dibenzoyl Peroxide (Benzoyl Peroxide)/clindamycin and adapalene/Dibenzoyl Peroxide (Benzoyl Peroxide), adapalene being a chemically stable retinoid that can be combined with Dibenzoyl Peroxide (Benzoyl Peroxide)[26] unlike tezarotene and tretinoin.
Combination products such as Dibenzoyl Peroxide (Benzoyl Peroxide)/clindamycin and Dibenzoyl Peroxide (Benzoyl Peroxide)/salicylic acid appear to be slightly more effective than Dibenzoyl Peroxide (Benzoyl Peroxide) alone for the treatment of acne lesions.

The combination tretinoin/Dibenzoyl Peroxide (Benzoyl Peroxide) was approved for medical use in the United States in 2021.
Dibenzoyl Peroxide (Benzoyl Peroxide) for acne treatment is typically applied to the affected areas in gel, cream, or liquid, in concentrations of 2.5% increasing through 5.0%, and up to 10%.
No strong evidence supports the idea that higher concentrations of Dibenzoyl Peroxide (Benzoyl Peroxide) are more effective than lower concentrations.


Mechanism of action:
Classically, Dibenzoyl Peroxide (Benzoyl Peroxide) is thought to have a three-fold activity in treating acne.
It is sebostatic, comedolytic, and inhibits growth of Cutibacterium acnes, the main bacterium associated with acne.

In general, acne vulgaris is a hormone-mediated inflammation of sebaceous glands and hair follicles.
Hormone changes cause an increase in keratin and sebum production, leading to blocked drainage. C. acnes has many lytic enzymes that break down the proteins and lipids in the sebum, leading to an inflammatory response.

The free-radical reaction of Dibenzoyl Peroxide (Benzoyl Peroxide) can break down the keratin, therefore unblocking the drainage of sebum (comedolytic).
It can cause nonspecific peroxidation of C. acnes, making it bactericidal,[6] and it was thought to decrease sebum production, but disagreement exists within the literature on this.

Some evidence suggests that Dibenzoyl Peroxide (Benzoyl Peroxide) has an anti-inflammatory effect as well.
In micromolar concentrations it prevents neutrophils from releasing reactive oxygen species, part of the inflammatory response in acne



APPLICATIONS OF DIBENZOYL PEROXIDE (BENZOYL PEROXIDE)
For some special applications it is desirable to use a dry Dibenzoyl Peroxide (Benzoyl Peroxide) powder as a catalyst.
For these cases the Dibenzoyl Peroxide (Benzoyl Peroxide) formulation Dibenzoyl Peroxide (Benzoyl Peroxide) was introduced, which is a mixture of Dibenzoyl Peroxide (Benzoyl Peroxide) and filler.
Dibenzoyl Peroxide (Benzoyl Peroxide) can be handled very easily and without risk.

Dibenzoyl Peroxide (Benzoyl Peroxide) contains no plasticizer and is lower concentrated than the usual Dibenzoyl Peroxide (Benzoyl Peroxide) formulations, which makes dosing easier.
One of the most important applications for Dibenzoyl Peroxide (Benzoyl Peroxide) is as a catalyst for putties based on unsaturated polyester resins.
A putty containing an accelerated polyester resin and Dibenzoyl Peroxide (Benzoyl Peroxide) cures rapidly so that after a short time the surface can be sanded and polished


Dibenzoyl Peroxide (Benzoyl Peroxide) is primarily used as a radical initiator to induce polymerisation (free radical polymerisation process), for the manufacture of e.g. expandible polystyrene in suspension, acrylics polymers (for road marking paints).
Dibenzoyl Peroxide (Benzoyl Peroxide) can also be used in other applications, in production, as an oxidant in anti-acne formulation, as a hardener of unsaturated polyester resins, as a cross-linking agent for the production of and silicone rubbers, and as a bleaching agent.


Dibenzoyl Peroxide (Benzoyl Peroxide)s are used to harden the resin in hot mold.
It is applied alone at high temperatures and with accelerators at room temperature.
Dibenzoyl Peroxide (Benzoyl Peroxide) paste;It is used together with marble adhesives in the hardening of polyester repair pastes used in automotive parts repair at ambient temperature.

Dibenzoyl Peroxide (DBPO) is primarily used in the manufacture of polymers, as a polymerisation initiator.
Dibenzoyl Peroxide (DBPO) can also be used in other applications: as an oxidant in anti-acne formulations, as a hardener/cross-linking agent (in production of unsaturated polyester resins and silicone rubbers) and as a bleaching agent.

Dibenzoyl Peroxide (DBPO) is in the form of white powder or paste with a molecular mass of 242 g/mol.
This material is available as a 75% pure powder for polymerization applications or as a 55% paste.
The percentage of active oxygen for this material should be at least 4.9%.

The half-life time of this substance in chlorobenzene is 10 hours at 71°C and 1 hour at 91°C.
Its bulk density at 20 degrees Celsius is 500 kg/m3.
Dibenzoyl Peroxide (DBPO) like other peroxide compounds starts to decompose at a temperature above 20 degrees Celsius.
Its storage time is a maximum of 6 months.


Dibenzoyl Peroxide (DBPO) is mainly used in production of plastics[5] and for bleaching flour, hair, plastics and textiles.
As a bleach, it has been used as a medication and a water disinfectant.

As a medication, Dibenzoyl Peroxide (DBPO) is mostly used to treat acne, either alone or in combination with other treatments.
Some versions are sold mixed with antibiotics such as clindamycin.
Dibenzoyl Peroxide (DBPO) is on the World Health Organization's List of Essential Medicines.

Dibenzoyl Peroxide (DBPO) is available as an over-the-counter and generic medication.
Dibenzoyl Peroxide (DBPO) is also used in dentistry for teeth whitening.
In 2021, it was the 284th most commonly prescribed medication in the United States, with more than 700,000 prescriptions



STRUCTURE AND REACTIVITY OF DIBENZOYL PEROXIDE (DBPO)
Structure of Dibenzoyl Peroxide (DBPO) from X-ray crystallography.
The O=C-O-O dihedral angle is 90°.
The O-O distance is 1.434 Å.

The original 1858 synthesis by Liebig reacted benzoyl chloride with barium peroxide,[15] a reaction that probably follows this equation:
2 C6H5C(O)Cl + BaO2 → (C6H5CO)2O2 + BaCl2
Dibenzoyl Peroxide (DBPO) is usually prepared by treating hydrogen peroxide with benzoyl chloride under alkaline conditions.
2 C6H5COCl + H2O2 + 2 NaOH → (C6H5CO)2O2 + 2 NaCl + 2 H2O

The oxygen–oxygen bond in peroxides is weak.
Thus, Dibenzoyl Peroxide (DBPO) readily undergoes homolysis (symmetrical fission), forming free radicals:
(C6H5CO)2O2 → 2 C6H5CO•2
The symbol • indicates that the products are radicals; i.e., they contain at least one unpaired electron.
Such species are highly reactive.

The homolysis is usually induced by heating.
The half-life of Dibenzoyl Peroxide (DBPO) is one hour at 92 °C. At 131 °C, the half-life is one minute.


In 1901, J. H. Kastle and his graduate student A. S. Loevenhart observed that the compound made the tincture of guaiacum tincture turn blue, a sign of oxygen being released.
Around 1905, Loevenhart reported on the successful use of Dibenzoyl Peroxide (DBPO) to treat various skin conditions, including burns, chronic varicose leg tumors, and tinea sycosis.
He also reported animal experiments that showed the relatively low toxicity of the compound.


Treatment with Dibenzoyl Peroxide (DBPO) was proposed for wounds by Lyon and Reynolds in 1929, and for sycosis vulgaris and acne varioliformis by Peck and Chagrin in 1934.
However, preparations were often of questionable quality.
It was officially approved for the treatment of acne in the US in 1960.
