1. Detergent composition (F) suitable for domestic or industrial use comprising, as thickener, a self-invertible inverse latex comprising an aqueous phase comprising:
a) a crosslinked anionic polyelectrolyte (P) consisting of:
at least one first monomer unit derived 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 selected from 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, partially salified or totally salified form;
at least one third monomer unit derived from a polyethylenic crosslinking monomer (AR),
b) ethylenediaminedisuccinic acid in trisodium salt form.
