The present invention relates to use of a compound for promoting antiredeposition during laundering of a textile fabric, in which the compound is a polymer comprising a polysaccharide backbone substituted by one or more groups -L-R1, where L represents an ester, amide or ether linkage and R1 represents an anionic alkyl group or a salt thereof, which has a degree of substitution of from 0.005 to 1 and a degree of biodegradation of at least 60% in 28 days. The use of such polymers in the manufacture of a laundry cleaning composition is also provided as well as laundry cleaning compositions containing such polymers.

La présente invention concerne l'utilisation d'un composé servant à favoriser l'antiredéposition pendant le blanchissage d'une étoffe, lequel composé est un polymère comprenant un squelette polysaccharide substitué par un ou plusieurs groupes L-R1,L désignant une liaison ester, amide ou éther et R1 désignant un groupe alkyle anionique ou un sel de celui-ci, qui présente un degré de substitution compris entre 0,005 et 1 et un degré de biodégradation d'au moins 60 % en 28 jours. Cette invention concerne également l'utilisation de tels polymères dans la fabrication d'une composition de nettoyage de blanchisserie ainsi que des compositions de nettoyage de blanchisserie contenant ces polymères.
