Date Jan. 8, 1998The present application relates to the use, as a cosmetic product, of crosslinked and at least 90% neutralized poly(2-acrylamido-2-methylpropanesulphonic acid) polymers. They generally comprise, distributed randomly: a) from 90 to 99.9% by weight of units of general formula (1) below: in which X+ denotes a cation or a mixture of cations, not more than 10 mol % of the cations X+ being able to be protons H+; b) from 0.01 to 10% by weight of crosslinking units derived from at least one monomer having at least two olefinic double bonds; the weight proportions being defined relative to the total weight of the polymer. The present application relates in particular to their use as thickener and/or gelling agent in cosmetic and/or dermatological compositions. |
