Novel method for improving the foaming properties of cleaning compositions for topical use

Composition (C1) characterised in that it comprises, for 100% of its mass:

• From 0.05% to 2% by mass of at least one crosslinked anionic polyelectrolyte (P) derived from the polymerisation of at least one monomer having a strong acid function, said monomer being 2-methyl 2-[(1-oxo 2-propenyl)amino]1-propanesulfonic acid partially or totally salified, with at least one neutral monomer chosen 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 represents a linear or branched alkyl radical comprising from eight to twenty carbon atoms and n represents a number greater than or equal to one and less than or equal to twenty, in the presence of at least one crosslinking agent;
• from 10% to 50% by mass of at least one foaming surfactant selected from elements of the group formed by the anionic surfactants, non-anionic surfactants and amphoteric surfactants.
• from 0.01% to 10% by mass of at least one acid agent (A) selected from the group consisting of the α-hydroxy acids and β-hydroxy acids, free, partially or completely salified.
• from 89.94% to 38% by mass of water,
• and in that the pH thereof is greater than or equal to 4.0 and less than or equal to 6.5.
