Patent ID: 6903208

Claim:
A substituted polysaccharide comprising β 1-4 linkages having covalently bonded on the polysaccharide moiety thereof, at least one deposition enhancing group which undergoes a chemical change in water at a use temperature to increase the affinity of the substituted polysaccharide to a substrate, the substituted polysaccharide further comprising one or more independently selected silicone chains; wherein the silicone chain(s) is or are independently selected from those of formula: wherein L is absent or is a linking group and one or two of substituents G 1 -G 3 is a methyl group, the remainder being selected from groups of formula the —Si(CH 3 ) 2 O— groups and the —Si(CH 3 O)(G 4 )- groups being arranged in random or block fashion; wherein n is from 5 to 1000, and m is from 0 to 100, G 4 is selected from groups of formula: —(CH 2 ) p —CH 3 , where p is from 1 to 18 —(CH 2 ) q —NH—(CH 2 ) r ,—NH 2 where q and r are independently from 1 to 3 —(CH 2 ) s —NH 2 , where s is from 1 to 3 where t is from 1 to 3 —(CH 2 ) u —COOH, where u is from 1 to 10, where v is from 1 to 10, and —(CH 2 CH 2 O) w —(CH 2 ) x H, where w is from 1 to 150, and x is from 0 to 10; and G 5 is independently selected from hydrogen, groups defined above for G 4 , —OH, —CH 3 and —C(CH 3 ) 3 .
