Abstract
New water-dispersible or water-soluble sulphonated polyesters with a number molecular mass lower than 20000, exhibiting a sulphur weight content of the order of 0.5 to 10% and a hydroxyl functional group content, expressed as OH equivalent/kg of polymer, higher than 0.2. They may be employed as antisoiling and/or antiredeposition agents and optionally detergents in detergent compositions, in rinsing, softening or antisoiling treatment compositions, for washing with or without pretreatment, rinsing, softening or the antisoiling treatment of textiles, especially those polyester-based.
