It is a zwitterionic ammonium compound and fatty acid amide that contains a long hydrocarbon chain and a polar group at each end. Cocamidopropyl betaine is used as a foam booster in shampoos, emulsifying agent, thickener, antistatic agent and rarely an antiseptic agent. Impurities formed during the manufacturing process are thought to increase the prevalence of contact sensitization and mild skin irritations."}]
