Surfactant mixtures

摘要

Surfactant mixtures which have foamability performance and/or cost advantages over the individual components consist of 5-85% 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 and 95-15% by weight of an alkylamidopropyldimethylbetaine in which the alkyl group contains 8-18 carbons. Preferred mixtures are those in which the amine oxide is N-tetradecyldimethylamine oxide and the betaine is cocoamidopropyldimethylbetaine.
