Abstract
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 R 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.
