INVERSE LATEX FOR A COSMETIC COMPOSITION COMPRISING A SPECIFIC CHELATING AGENT AND A POLYELECTROLYTE COMBINING A STRONG ACID FUNCTION AND A NEUTRAL FUNCTION

摘要

The invention relates to a self-invertible inverse latex having an aqueous phase, comprising: a) a cross-linked anionic polyelectrolyte (P) consisting of: - at least one first monomer unit derived from 2-methyl -2-[(1-oxo-2-propenyl)amino]1-propane sulfonic acid in the form of a free or partially or totally salified acid; and - at least one second monomer unit derived from at least one monomer selected from the elements of the group consisting of (2-hydroxyethyl)acrylate, (2,3-dihydroxypropyl)acrylate, (2-hydroxyethyl)methacrylate, (2,3-dihydroxypropyl)methacrylate, or vinylpyrrolidone; and - at least one monomer unit derived from a cross-linking polyethylenic monomer (AR); b) at least one chelating compound (SQ) selected from the elements of the group consisting of ethylenediamine disuccinic acid in the form of trisodium salt, tetrasodium salt of glutamic acid, N,N diacetic, or the sodium salt of imminosuccinic acid.
