Patent ID: 7012048

Claim:
A composition which comprises: about 0.01 to about 20% by weight of a cationic ampholytic polymer; and about 0.01 to about 20% by weight of an anionic benefit agent, wherein the ampholytic polymer comprises a poly(vinyl pyridine) of formula I: wherein a represents a mole % of 1 to 99, b represents a mole % of 1 to 99, and c represents a mole % of 0 to 98; R 1 is selected from the group consisting of (CR 6 R 7 ) m1 ; R 2 is selected from a group consisting of (CR 8 R 9 ) m2 , benzyl, benzene, and substituted benzene; Z is a residue incorporated into the polymer from an ethylenically unsaturated monomer; m 1 and m 2 are independently 0 to 20; are each R 6 , R 7 , R 8 , and R 9 are independently selected from the group consisting of hydrogen, hydroxyl, alkyl, aryl, or alkaryl and may differ in each repeating unit; and D is selected from groups bearing an anionic charge selected from the group consisting of: SO 3 − , SO 2 − , CO 2 − , PO 3 − , and PO 4 − ; and R 3 , R 4 , R 5 , R 10 , R 11 , and R 12 , are independently H or alkyl.
