摘要：
Surfactant mixtures having improved foamability and/or cost performance consist of 5-90% by weight of an amine oxide corresponding to the formula RR'R"NO in which R is a primary alkyl group containing 6-24 carbons and R' and R" are independently selected from methyl, ethyl, and 2-hydroxyethyl, 5-90% by weight of an alkanolamide, and 5-60% by weight of an alkyl sarcosinate. Preferred mixtures are those in which the amine oxide is N-tetradecyldimethylamine oxide, the alkanolamide is cocodiethanolsuperamide, and the sarcosinate is sodium lauryl sarcosinate.
