Abstract
The use of copolymers to obtain detergent or cosmetic compositions which are stable to phase separation, where the copolymers have the general formula: EQU (X).sub.a --(Y).sub.b --(Z).sub.c in which PA1 X is an anionic monomer unit; PA1 Y is a nonionic monomer unit; and PA1 Z is a cationic monomer unit; PA1 a is the weight percentage of X in the copolymer, based on the total weight of all monomers, and is 95 to 15 wt. %; PA1 b is the weight percentage of Y in the copolymer, based on the total weight of all monomers, and is 0 to 65 wt. %; and PA1 c is the weight percentage of Z in the copolymer, based on the total weight of all monomers, and is 5 to 60 wt. %.
