摘要：
The invention relates to a method for improving the foaming properties of cleaning compositions for topical use, having a pH of no lower than 4.0 and no higher than 6.5, and including at least one foaming surfactant, said method being characterized in that an effective quantity of a cross-linked anionic polyelectrolyte (P) is incorporated into said cleaning composition for topical use, said cross-linked anionic polyelectrolyte being obtained through the polymerization, in the presence of at least one cross-linking agent, of at least one monomer having a strong acid function, said monomer being 2-methyl 2-[(1-oxo 2-propenyl) amino] 1-propanesulfonic acid, which is partially or completely salified, with at least one neutral monomer selected from the N,N-dialkyl acrylamides, wherein each of the alkyl groups comprises between one and four carbon atoms and at least one monomer of formula (I), in which R is a linear or branched alkyl radical comprising eight to twenty carbon atoms, and n is a number greater than or equal to one and less than or equal to twenty. The invention also relates to novel compositions which contain the polyelectrolyte (P), foaming surfactants, and acid agents selected from among the α-hydroxy acids and β-hydroxy acids, as well as to the use thereof in cosmetics.Procédé pour améliorer les propriétés moussantes d'une formulation nettoyante à usage topique, de pH supérieur ou égal à 4,0 et inférieur ou égale à 6,5 et comprenant au moins un agent tensioactif moussant, ledit procédé étant caractérisé en ce que l'on incorpore dans ladite formulation nettoyante à usage topique, une quantité efficace d'un polyélectrolyte anionique réticulé (P) issu de la polymérisation, en présence d'au moins un agent de réticulation, d'au moins un monomère possédant une fonction acide fort, ledit monomère étant l'acide 2-méthyl 2-[(1-oxo 2-propènyl) amino] 1-propanesulfonique, partiellement ou totalement salifiée, avec au moins un monomère neutre choisi parmi les N,N-dia
