Novel inverse latices self-invertible with respect to fatty acid esters, and cosmetic, dermocosmetic, dermopharmaceutical or pharmaceutical compositions comprising them

摘要

Composition comprising an oil phase, an aqueous phase, at least one emulsifying agent of water-in-oil (W/O) type and at least one emulsifying agent of oil-in-water (O/W) type in the form of a self-invertible inverse latex comprising from 20% to 70% by weight and preferably from 25% to 50% by weight of a branched or crosslinked polyelectrolyte, characterized in that the said 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. Cosmetic, dermocosmetic, dermopharmaceutical or pharmaceutical composition comprising it.
