INVERSE LATEX SELF-INVERTIBLE WITH RESPECT TO FATTY ACID ESTER, AND COSMETIC COMPOSITION, DERMOCOSMETIC COMPOSITION, DERMOPHARMACEUTICAL COMPOSITION OR PHARMACEUTICAL COMPOSITION COMPRISING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a new polymer emulsion to which the skin is tolerable. SOLUTION: This composition comprises an oil phase, an aqueous phase, at least one emulsifying agent of water-in-oil type and at least one emulsifying agent of oil-in-water type in the form of a self-invertible latex comprising from 20% to 70% by weight of a branched or crosslinked polyelectrolyte, characterized in that the polyelectrolyte is either a homopolymer based on a monomer having either a partially or completely salified strong acid functional group or a partially or completely salified weak acid functional group, or a copolymer based on at least one monomer having a strong acid functional group copolymerized either with at least one monomer having a weak acid functional group or with at least one neutral monomer, or a copolymer based on at least one monomer having a weak acid functional group copolymerized with at least one neutral monomer, and characterized in that the constituent solvent of the oil phase is chosen from fatty acid esters.
