Abstract: A cross-linked anionic polyelectrolyte resulting from the polymerization, for 100 mol %: (i) of a proportion no smaller than 30 mol % and smaller than 99.5 mol % monomer units from a monomer having a partially or totally salified strong acid function; (ii) of a proportion no smaller than 0.5 mol % and no greater than 5 mol % monomer units from at least one monomer having Formula (I): CH2?CH(CH3)—C(=0)—OR1 (I), wherein Ri is an alkyl radical including 6 to 18 carbon atoms; (iii) of a proportion greater than 0 mol % and no greater than 5 mol % monomer units from at least one diethylene or polyethylene cross-linking monomer; and (iv) optionally, of a proportion smaller than 69.5 mol % monomer units from a neutral monomer. Also, a method for preparing the polyelectrolyte and to the use thereof as a thickener in topical compositions.
