    摘要: A pourable amine oxide composition which is suitable for use in detergent compositions is obtained by reacting a tert-amine with aqueous hydrogen peroxide in a nonionic surfactant as the sole organic solvent, at least a portion of the nonionic surfactant being a fatty alkanolamide corresponding to the formula ZC(O)NZ'Z" in which Z is an alkyl group containing 4-30 carbons, Z' is hydrogen or an alkyl or hydroxyalkyl group containing 1-3 carbons, and Z" is a hydroxyalkyl group containing 1-3 carbons. When the composition has a low water content, it is suitable for use in water-sensitive formulations, such as bar soaps and detergent concentrates.
