Patent ID: 8242097

Claim:
At least one grafted polysaccharide compound comprising at least one non-polymer siloxane graft, wherein the grafted polysaccharide compound is obtained by reacting at least one polysaccharide and at least one siloxane compound of formula (I): wherein: R is independently chosen from linear and branched C 1 -C 12 alkyl groups and linear and branched C 2 -C 8 alkenyl groups; A is chosen from linear or branched C 1 -C 6 alkylene groups and linear or branched C 2 -C 8 alkenylene groups, and optionally comprising in the chain, a heteroatom chosen from nitrogen, oxygen, and sulfur atoms, and wherein the alkylene and alkenylene groups optionally comprise at least one hydroxyl substituent; Z is chosen from —NHR 4 , — + NR 1 R 2 R 3 X − , —C≡N, —SH, —OH, guanidine, guanidinium salts, sulfonate salts, sulfate salts, phosphate salts, and phosphonate salts, wherein the salts may be chosen from organic and mineral salts; R 4 is chosen from a hydrogen atom and linear and branched C 1 -C 22 alkyl groups, optionally comprising at least one hydroxyl and/or quaternary ammonium substituent; R 1 , R 2 , and R 3 are each independently chosen from a hydrogen atom and linear or branched C 1 -C 22 alkyl groups, optionally comprising at least one hydroxyl substituent; and X is chosen from mineral and organic anions; and wherein the at least one polysaccharide is chosen from a hemicellulose, a lignocellulose, a starch, an inulin, a guar gum, a xanthan gum, a pullulan, an agar-agar, a sodium, potassium or ammonium alginate, a carrageenan, a dextran, a furcellaran, a gellan gum, a gum arabic, a gum tragacanth, a hyaluronic acid, a konjac mannan, a lignin sulfonate, a carob gum, a partially N-acetylated chitin, a pectin, a polydextrose, a rhamsan gum, and a welan gum.
