Abstract:
1. A fabric treating composition in the form of a solid or concentrated aqueous dispersion which comprises: (A) from 0.05% to 10% by weight of nanoparticles or at least one nanolatex of at least one addition polymer (P3) which is insoluble under the working conditions of said composition in an aqueous or wet medium, said addition polymer (P3) containing amphoteric units, and comprising: (1) at least 70% of the total mass of said polymer of hydrophobic monomer units (N) derived from vinylaromatic monomers, alkyl esters of α-β monoethylenically unsaturated acids, vinyl or allylic esters of saturated carboxylic acids, or a-F (2) at least 0.1% and not more than 20% of the total mass of said polymer of amphoteric hydrophilic monomer units (F (3) optionally, uncharged or non-ionizable hydrophilic monomer units (F (4) optionally, cationic or cationizable hydrophilic monomer units (F (5) optionally, at least one crosslinking unit (R) derived from divinylbenzene, ethylene glycol dimethacrylate, allyl methacrylate, methylenebis(acrylamide) or glyoxal bis (acrylamide); (B) from about 3% to about 50% by weight of at least one anionic, cationic, nonionic and/or amphoteric surfactant; and (C) optionally, other detergent adjuvants; the combination of hydrophilic monomer units representing at least 1% of the weight of the polymer (P3), the molar ratio of cationic charges to anionic charges ranging from 1/99 to 80/20, said nanoparticles or the said nanolatex have a mean particle size of polymer of from 10 to 500 nm; and the addition polymer (P3) being present in an amount sufficient to impart crease-resistant, softening or pre-spotting characteristics to the fabric treating composition.
