摘要

Title: reverse emulsion for cosmetic composition, including a special isolating agent and a polyelectrolyte combining strong and weak acid functionsA self reversible inverse emulsion comprising an aqueous phase, comprising:(a) The crosslinked anionic polyelectrolyte (P) comprises:At least one first monomer unit generated from 2-methyl-2 - [(1-oxo-2-propenyl) amino] 1-propanesulfonic acid as a free acid or partially or completely salinizing acid;At least one second monomer unit of at least one monomer selected from the group elements consisting of acrylic acid, methacrylic acid, 2-carboxyethyl acrylic acid, itaconic acid, maleic acid and 3-methyl 3 - [(1-oxo-2-propyl) amino] butyric acid, The carboxyl function of the monomer is free acid, partial salinization or complete salinization; andAt least one third monomer unit from a polyethylene crosslinking monomer (AR),(b) Acid ethylenediamine bisuccinate in the form of trisodium salt.
