Post  jindi on Fri Jul 31, 2009 12:16 am

Cocamidopropyl betaine is a synthetic surfactant derived from coconut oil and dimethylaminopropylamine.It is a zwitterionic

chemical compound with a quaternary ammonium cation. It is a viscous pale yellow transparent liquid and is used as a surfactant in

bath products such as shampoos and hand soaps, and in cosmetics as an emulsifying agent and thickener, and to reduce irritation

purely ionic surfactants would cause. It also serves as an antistatic agent in hair conditioners.

Cocamidopropyl betaine is a derivate of cocamide and glycine betaine (a form of betaine). See cocamide for the discussion of the

length of carbon chain in the molecule.

Cocamidopropyl betaine is a medium strength surfactant which most often does not irritate skin or mucous membranes. That said,

some studies indicate it is an allergen. It also has antiseptic properties, making it suitable for personal sanitary products. It is

compatible with other cationic, anionic, and nonionic surfactants .camidopropyl betaine to a significant degree has replaced

cocamide cocamidopropyl betaine Cocamidopropyl betaine is the active

ingredient in Johnson & Johnson's Baby wash
