Abstract:
A hair setting composition comprising as film-formers copolymers consisting essentially of tert-butyl acrylate or tert-butyl methacrylate having a K value of from 10 to 50 which are obtained by free-radical polymerization of monomers consisting ofA) from 50 to 72% by weight, based on the total weight of monomers employed in the polymerization, of tert-butyl acrylate or tert-butyl methacrylate or a mixture thereof as monomer A, B) from 12 to 25% by weight, based on the total weight of monomers employed in the polymerization, of acrylic acid or methacrylic acid or a mixture thereof as monomer B, and C) from 3 to 38% by weight, based on the total weight of monomers employed in the polymerization, of a free-radically copolymerizable monomer capable of forming a homopolymer having a glass transition temperature of less than 30Â° C., which monomer is ethyl acrylate, wherein any carboxyl groups present in the copolymer are partially or completely neutralized.
