NOVEL METHOD FOR IMPROVING THE FOAMING PROPERTIES OF CLEANING COMPOSITIONS FOR TOPICAL USE

摘要

Method for improving foaming properties of cleaning compositions for topical use, having a 4.0≦pH≦6.5, and including at least one foaming surfactant, includes incorporating an effective quantity of a cross-linked anionic polyelectrolyte into the cleaning composition, the cross-linked anionic polyelectrolyte being obtained through polymerization, in the presence of at least one cross-linking agent, of at least one monomer having a strong acid function, the 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 includes between one and four carbon atoms and at least one monomer of formula (I), in which R is a linear or branched alkyl radical including eight to twenty carbon atoms, and n is a number greater than or equal to one and less than or equal to twenty.

1. Method for improving the foaming properties of a cleaning formulation for topical use, with a pH greater than or equal to 4.0 and less than or equal to 6.5 and comprise at least one foaming surfactant, said method being characterised in that an effective quantity of a crosslinked anionic polyelectrolyte (P) derived from polymerisation is incorporated in said cleaning formulation for topical use, in the presence of at least one crosslinking agent and at least one monomer having a strong acid function, said monomer being 2-methyl 2-[(1-oxy 2-propenyl)amino]1-propanesulfonic acid, partially or completely salified, with at least one neutral monomer chosen from the N,N-dialkyl acrylamides, in which 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.
