ABSTRACT:
Surfactant mixtures which provide denser foams than the individual components consist of 50-90% 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 and 50-10% by weight of an alkylbenzenesulfonate surfactant. Preferred mixtures are those in which the amine oxide is N-tetradecyldimethylamine oxide and the alkylbenzenesulfonate surfactant is sodium dodecylbenzenesulfonate.
