Abstract
Surfactant mixtures which have performance and/or cost advantages over either component alone consist of 5-95% 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 95-5% by weight of a fatty acid alkanolamide. Preferred mixtures are those in which the amine oxide is N-tetradecyldimetylamine oxide and the alkanolamide is cocodiethanolsuperamide.
