Beschreibung
Zusammenfassung:A cosmetic and/or dermatological composition comprising an aqueous dispersion of lipid vesicles containing at least one cross-linked poly(2-acrylamido-2-methylpropanesulphonic acid) polymer which is at least 90% neutralized, comprising, distributed in a random manner: a) from 90 to 99.9% by weight of units of formula (1): in which X+ denotes at least one cation wherein no more than 10 mol % of the cations X+ are protons H+; b) from 0.01 to 10% by weight of cross-linking units obtained from at least one monomer having at least two olefinic double bonds; wherein the percentages by weight are relative to the total weight of the polymer.
