Benzoyl peroxide (BPO) is an organic compound in the peroxide family. It consists of two benzoyl groups bridged by a peroxide link. It is one of the most important organic peroxides in terms of applications and the scale of its production. Benzoyl peroxide is used as an acne treatment, for bleaching hair and teeth. Adverse reactions are: dryness and urticarial reaction, contact dermatitis, application site burning, application site irritation and skin irritation.

The aluminum salt of Allantoin, Alcloxa combines the astringent and anti-microbial properties of aluminum with the anti-irritant, soothing and healing properties of Allantoin. Alcloxa is particularly suited for use in anti-perspirants, acne treatments and foot care products. Alcloxa is a compound that combine the properties of aluminum salts with the properties of allantion. The allantion component ehhances the action of the aluminum salts and serves to overcome irritations experienced by many individuals who may be sensitive to the use of aluminum alts. The aluminum component reduces sweat by causing the sweat gland ducts swell. Alcloxa also add to the antiperspirant properties the deodorant effect because of its bacteriostatic action. It showed bacteriostatic properties at concentrations of 0.2% particularly against Gram bectaria (B. subtilis, S. aureus, P. vulgaris, Pityrosporum ovale). This is ascribable to two different mechanisms: first bacterial growth is retarded due to a decrease in the amount of water present, second aluminum salt have itself an antimicrobial action. In baby products is indicated for its healing reparative action, in the treatment of diaper rash. Also is approved in haemorrhoidal product for its soothing and keratolytic action. In oral care products Alcloxa is useful for its astringent antibacterial properties. It is very indicated in formulations for sensitive teeth, periodontal and gum diseases (like gingivitis, irritable and bleeding gums). Use levels: 0.1-1%. − In antiacne products the slightly astringent effect promotes healing of pustules and acne lesions. It reduces the extension of infected skin eruptions, healing them and developing a soothing action. May be used alone or also in combinations with other antimicrobial agents in order to fight acne more effectively. Use levels: 0.5-2.0%.

Hydrogen peroxide has been used in medicine for more than 100 years. It is known in surgery as a highly useful irrigation solution by virtue of both its hemostatic and its antimicrobial effects. Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/cold sores, gingivitis). This product works by releasing oxygen when it is applied to the affected area. The release of oxygen causes foaming, which helps to remove dead skin and clean the area. Hydrogen peroxide is a strong oxidizing agent used in aqueous solution as a ripening agent, bleach, and topical anti-infective. It is relatively unstable and solutions deteriorate over time unless stabilized by the addition of acetanilide or similar organic materials.
