Question: Galderma S.A., which markets Adapalene/benzoyl peroxide, is a subsidiary of what company
Context: Peroxybenzoic acid is a simple peroxy acid.  It may be synthesized from benzoic acid and hydrogen peroxide, or by the treatment of benzoyl peroxide with sodium methoxide, followed by acidification. The drug combination benzoyl peroxide/clindamycin is a topical gel used for the treatment of acne.  It is sold under the trade names Duac (by Stiefel Labs) and BenzaClin (by Sanofi Aventis).  Both contain 1% clindamycin phosphate, an antibiotic, and 5% benzoyl peroxide, an antiseptic.  Another brand is Onexton (by Valeant) with 1.2% clindamycin phosphate and 3.75% benzoyl peroxide.  All formulations are prescription drugs. Stridex (originally spelled Stri-Dex) is an American acne treatment and prevention medicine, originally registered trademark of Bayer Corporation.  It comes in the form of fibrous pads saturated with astringents and contained in a plastic tub of fifty-five to ninety pads.  Most products in the Stridex line contain as the active ingredient salicylic acid (0.5–2.5%); Stridex "Power Pads", however, contain instead benzoyl peroxide (2.5%), which is considered by medical professionals to be "the most effective and widely used nonprescription medication for both types of acne".  However, they also warn about possible side effects: dryness of the skin, possible burning, and tingling.  Patients are advised to apply treatment with caution around lips, nose and mouth, or cuts and scrapes, and also avoid excessive sun exposure.  In 2013, FDA started to investigate a possible link between benzoyl peroxide- and/or salicylic acid-based acne prevention medicine with hypersensitivity and anaphylactic reactions without calling off any products or placing warnings. Organic peroxides are organic compounds containing the peroxide functional group (ROOR′).  If the R′ is hydrogen, the compounds are called organic hydroperoxides.  Peresters have general structure RC(O)OOR.  The O−O bond easily breaks, producing free radicals of the form RO.  Thus, organic peroxides are useful as initiators for some types of polymerisation, such as the epoxy resins used in glass-reinforced plastics. MEKP and benzoyl peroxide are commonly used for this purpose.  However, the same property also means that organic peroxides can either intentionally or unintentionally initiate explosive polymerisation in materials with unsaturated chemical bonds, and this process has been used in explosives.  Organic peroxides, like their inorganic counterparts, are powerful bleaching agents. Galderma S.A. is a pharmaceutical subsidiary specializing in the research, development and marketing of dermatological treatments and became a wholly owned subsidiary of Nestlé in 2014. Donald Holroyde Hey FRS (12 September 1904 – 21 January 1987) was a Welsh organic chemist.  He was notable for his paper proposing that the decomposition of benzoyl peroxide gave rise to free phenyl radicals. Adapalene/benzoyl peroxide is a prescription drug combination for the treatment of severe acne vulgaris; marketed by Galderma under the trade name Epiduo.  Its trade name in Canada is TactuPump, where it was previously known as Tactuo. This page provides supplementary chemical data on benzoyl peroxide. Clearasil is an American brand of skin care and acne medication, whose products contain chiefly benzoyl peroxide, sulfur & resorcinol, triclosan, or salicylic acid as active ingredients.  Clearasil has a wide range of products both for rapid and sometimes slow acne treatment and for everyday prevention.  The products are marketed to customers worldwide. Benzamycin is a topical gel containing of 5% benzoyl peroxide and 3% erythromycin.  Developed and manufactured by Dermik Laboratories, its main usage is to fight acne.  Benzamycin is a prescription medication.
