摘要：
The 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: ##STR1## in which X.sup.+ denotes a cation or a mixture of cations, not more than 10 mol % of the cations X.sup.+ being able to be protons H.sup.+ ;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.
