A polymer for use in a composition or method of laundry treatment is a copolymer of: (a) one or more anionic monomer units; (b) one or more cationic monomer units; and (c) optionally, one or more uncharged monomer units; wherein, the number ratio of the total of all negative charges on the anionic monomer unit(s) to the total of all positive charges on the cationic monomer unit(s) is from 10 : 1 to 3 : 1, especially from 17 : 3 to 3 : 1.

L'invention concerne un polymère destiné à être utilisé dans une composition ou une méthode de traitement du linge. Ce polymère est un copolymère composé de: (a) une ou plusieurs unités monomères anioniques; (b) une ou plusieurs unités monomères cationiques; et (c) éventuellement, une ou plusieurs unités monomères non chargées, le rapport numérique entre la totalité des charges négatives sur les unités monomères anioniques et la totalité des charges positives sur les unités monomères cationiques est compris entre 10: 1 à 3: 1, notamment entre 17: 3 et 3: 1.
