Octadecanoylamidopropyldimethylamine, Tegamine S 13, Stearic acid, 3-dimethylaminopropylamide, Dimethylaminopropyl stearamide, Lexamine S 13, Stearamidopropyl dimethylamine


Cation-active fatty acid amino amide found in hair conditioners. Reacts simultaneously with DMAPA and amidoamine may represent cross-reactivity. Subjects with contact allergy to cocamidopropylbetaine (CAPB) have positive reactions to 3-dimethylaminopropylamine (DMAPA). DMAPA may in fact act as the true sensitizing substance, while amidoamine, which may in any case release DMAPA in vivo as a result of enzymatic hydrolysis, may favour the transepidermal penetration of the sensitizing agent.
