Inverse latex for a cosmetic composition comprising a specific sequestering agent and a polyelectrolyte combining a strong acid function and a weak acid function

A self-invertible inverse latex comprising an aqueous phase comprising:

• a) a crosslinked anionic polyelectrolyte (P) consisting of:
• at least one first monomer unit resulting from 2-methyl-2-[(1-oxo-2-propenyl)amino]-1-propanesulfonic acid in free acid form or partially or totally salified form;
• and
• at least one second monomer unit derived from at least one monomer chosen from the elements of the group consisting of acrylic acid, methacrylic acid, 2-carboxyethylacrylic acid, itaconic acid, maleic acid, 3-methyl-3-[(1-oxo-2-propenyl)amino]butanoic acid, the carboxylic function of said monomers being in free acid form or partially salified or totally salified form;
• and
• at least one third monomer unit derived from a polyethylenic crosslinking monomer (AR), and
• b) ethylenediaminedisuccinic acid in trisodium salt form, in an amount of at least 250 molar ppm calculated relative to the molar sum of said first and second monomer units.
