Abstract
Surfactant compositions which provide acceptable foamability at a lower cost than amine oxide/alkyl sulfate mixtures consist of (A) 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, (B) 5-85% by weight of an alkyl sulfate surfactant, and (C) 10-50% by weight of a normally liquid polyalkylene glycol.
