Listed below are links to weblogs that reference FDA: WTF?:
Actually, I'm not surprised. Long ago, when Oxy-5 first came out, my father expressly forbade me to use it. He was a research chemist and he knew that it had once been classified as a carcinogen by the FDA.
As late as 1995, its carcinogenic potential was still being assessed: "While benzoyl peroxide is not a complete carcinogen in animals and has weak or no mutagenic potential, it has been found to be a tumor promoter in mouse skin using experimental two-stage models of carcinogenesis."
The EU has banned it from skin care ingredients, according to another site:
"Though it may be effective for mild acne, benzoyl peroxide is not free from adverse effects according to the European Commission.
"The most common adverse effect is extreme dryness and premature aging of skin. ... It can also causes irritation, stinging, burning and peeling of skin. A formulation containing 2.5% benzoyl peroxide was found to have less burning and peeling of skin as compared with 5% or 10% benzoyl peroxide (Mills et al. 1986). Allergic contact dermatitis was found in 1-2% patients using benzoyl peroxide (Ives, 1992). ... Acne preparations made of benzoyl peroxide may contain various other chemical ingredients. Glycolic acid is a photo sensitizer and may be toxic to gastrointestinal system, nervous system and kidneys. Triethanolamine can form carcinogenic nitrosamine compounds on the skin or in the body after absorption. It may also elicit immune reaction in form of allergic dermatitis or asthmatic attacks. Diisopropanolamine may release carcinogenic nitrosamine compounds."
Nice, eh? I'd rather have the acne, thanks very much.
