APPLICATION IN THE COSMETIC OF A CROSSLINKED AND AT LEAST IN 90 NEUTRALISED 2-ACRYLAAMIDO2-METHYLPROPANESULPHONIC (POLY)ACID AND OF LOCALLU-APPLIED COMPOSITIONS CONTAINING SUCH ACID

摘要

The present application relates to the use as a cosmetic product in acid polymers, poly (acrylamido 2 - 2 - methylpropane sulphonic) crosslinked and neutralized with at least 90%. It generally comprise, distributed randomly: & br / a) of 90 to 99,9% by weight of units of general formula (1): & br / (see appended drawing in bopi) & br / in which x * * + denotes a cation or a mixture of cations, at most 10% mol of the cations x * * + may be of the protons (h * * +; & br / b) of 0,01 to 10% by weight of crosslinking units derived from at least one monomer containing at least two olefinic double - connections; the proportions by weight being defined with respect to the total weight of the polymer. & br / the present application relates, in particular their use as thickening agent and / or gelling agents in cosmetic compositions and / or dermatological compositions.
