The copolymers are useful as components in aqueous hair shampoo systems to provide an after-shampoo conditioning effect.
Claims8
A shampoo composition comprising an aqueous solution containing 1 to 10% by weight of a compound having the formula ##STR3## In which the molar ratio of X to Y is from 3:1 to 1:2, in which R is a straight or branched chain alkyl group having 4-18 carbon atoms, in which R.sub.1 is --CH.sub.3 when R.sub.2 is --H, in which R.sub.1 is --H when R.sub.2 is --CH.sub.3, in which the ratio of carbon atoms to --OSO.sub.3 M groups is from 1:8 to 1:16, and in which M is sodium, potassium or triethanolamine, in combination with 5-25% by weight of a surface active agent selected from the class consisting of anionic, nonionic, and ampholytic surface active agents.
A compound of the formula ##STR4## in which the molar ratio of X to Y is from 3:1 to 1:2, in which R is a straight or branched chain alkyl group having 4 to 18 carbon atoms, in which R.sub.1 is --CH.sub.3 when R.sub.2 is --H, in which R.sub.1 is --H when R.sub.2 is --CH.sub.3, in which the ratio of carbon atoms to --OSO.sub.3 M groups is from 1:8 to 1:16, and in which M is sodium, potassium, or triethanolamine.
