Abstract
Amphoteric copolymers of general formula: EQU (X).sub.a --(Y).sub.b --(Z).sub.c in which PA1 X represents a monomer type with anionic charge; PA1 Y represents a monomer type with nonionic character; PA1 Z represents a monomer type with cationic charge; PA1 a is the weight % based on the total weight of monomers of X, and is between 95 and 15; PA1 b is the weight % based on the total weight of monomers of Y, and is between 0 and 65; PA1 c is the weight % based on the total weight of monomers of Z, and is between 5 and 60 as rheological modifiers of lamellar phases of detergent or cosmetic (liquid or pasty) compositions are disclosed. Liquid washing detergent and liquid shampoos containing the amphoteric copolymers are also disclosed.
