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.

Water-dispersible ou water-soluble novo sulphonated poliésteres com um número mais baixa de 20000 maciços molecular, exibindo um índice do peso do enxôfre da ordem de 0.5 a 10% e um índice funcional do grupo do hydroxyl, expressada como OH equivalent/kg do polímero, mais altamente de 0.2. Podem ser empregados como antisoiling e/ou agentes e opcionalmente detergentes do antiredeposition em composições detergentes, composições no tratamento enxaguar, amaciar ou antisoiling, para lavar-se com ou sem pretreatment, enxaguar, amaciar ou o tratamento antisoiling dos textiles, especial aqueles poliéster-baseados.
