Abstract:
1. A cationically and hydrophilically modified galactomannan having an average mannose to galactose ratio of at least 5:1 wherein a portion of the hydrogen atoms of the hydroxyl groups present on the galactomannan are substituted with a least one cationic moiety represented by formula (I) and at least one hydrophilic moiety represented by formula (II) as follows: wherein A, independently, is selected from a divalent linear or branched, substituted or unsubstituted C 1 -C 6 alkylene radical, and when substituted said substituent, independently, is selected from hydroxyl and halo; R, independently, is selected from —S + R 3 R 4 X − , —N + R 3 R 4 R 5 X − , and —P + R 3 R 4 R 5 X − , wherein R 3 and R 4 , and R 5 , independently, are selected from hydrogen and linear and branched C 1 -C 24 alkyl, and X − represents an anion; (R 1 —O) c represents a polyoxyalkylene moiety arranged as a homopolymer, a random copolymer or a block copolymer of oxyalkylene units, wherein R 1 , independently, is selected from linear and branched C 2 H 4 , C 3 H 6 , and C 4 H 8 divalent alkylene groups, and c is an integer ranging from about 2 to about 250; R 2 , independently, is selected from hydrogen, methyl, and AR; and a is 0 or 1; b is 0 or 1, subject to the proviso that when a is 0, b is 0, and when R 2 is AR in formula (II), the cationic moiety AR represented by formula (I) is optionally present.
