Abstract
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 an alkylphenol ethoxylate or other compound corresponding to the formula Z[OC(Z')HCH.sub.2 ].sub.m OH in which Z is an alkylphenyl group wherein the alkyl group contains 4-30 carbons, Z' is hydrogen or an alkyl or hydroxyalkyl group containing 1-3 carbons, and m is an integer of 1-100. When the composition has a low water content, it is suitable for use in water-sensitive formulations, such as bar soaps and detergent concentrates.
