Abstract
Detergent composition (F) for domestic or industrial use including, as thickener, a self-invertible inverse latex including an aqueous phase including: a) a crosslinked anionic polyelectrolyte (P) consisting of: at least one 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; —at least one monomer unit derived from at least one monomer chosen from the elements of the group consisting of acrylamide, N,N-dimethylacrylamide, ethacrylamide, N-isopropylacrylamide, N-tert-butylacrylamide; and at least one monomer unit derived from a polyethylenic crosslinking monomer (AR), b) ethylenediaminedisuccinic acid in trisodium salt form.
