Abstract
Use in association, as oil thickners, in a cosmetic composition comprising an oily phase, of at least one first copolymer including patterns derived from at least one lipophilic monomer and patters derived from at least one hydrophilic monomer, comprising at least one carboxylic acid or sulphonic grouping, and of at least one second copolymer including patterns derived from at least one lipophilic monomer and patterns derived from at least one hydrophilic monomer comprising at least one amine, amide, alcohol or ether grouping. Said first and second copolymers have a molecular weight of not less than approximately 100 000. The association enables thickened composition to be obtained, the texture, look and feel of which correspond to a cosmetic use.
