Patent ID: 7153821

Claim:
A laundry cleaning composition comprising a graft polymer benefit agent and at least one additional laundry cleaning ingredient, the graft polymer benefit agent having the general formula in which each SU represents a sugar unit in a polysaccharide backbone; a represents the number of unsubstituted sugar units as a percentage of the total number of sugar units and is in the range from 0 to 99.9; b represents the number of substituted sugar units as a percentage of the total number of sugar units and is in the range from 0.1 to 100; m represents the degree of substitution per sugar unit and is from 1 to 3; W represents a group —O— or —NR 1 —, where R 1 represents a hydrogen atom or an optionally substituted alkyl group; p, q and r are each independently 0 or 1; L represents an optionally substituted alkylene, cycloalkylene, arylene or heteroarylene group; X and Y each independently represent a group —CH 2 —, —CO—, —O—CO—, —CO—O—, —NH—CO—, —CO—NH—, —CH(OH)—CH 2 —, —CH 2 —CH(OH)—, —CH 2 —O—CO—, —CO—O—CH 2 —, —CH 2- CO—O—, —O—CO—CH 2 —, —O—CO—NH—, —NH—CO—O—, —(CR 2 R 3 ) s —CO—, —CO—(CR 2 R 3 ) s —, —(CR 2 R 3 ) t —O—, —O—(CR 2 R 3 ) t —, —(CR 2 R 3 ) u —SO—, —SO—(CR 2 R 3 ) u —, —(CR 2 R 3 ) v—SO 2 —, —SO 2 —(CR 2 R 3 ) v — or —NH—CO—NH, where s, t, u and v are each independently 0, 1, 2 or 3 and R 2 and R 3 each independently represent a hydrogen atom or an optionally substituted alkyl; Z 1 represents a group R 4 and R 5 each independently represent an optionally substituted alkyl, cycloalkyl or aralkyl group, R 6 represents a hydrogen atom or an optionally substituted alkyl group, w is 0, 1, 2, 3, or 4; and R 7 represents a hydrogen atom or an optionally substituted alkyl group; P represents a polymer chain, Hal 2 represents a halogen, and k is from 10 to 200.
