Patent ID: 7671007

Claim:
A personal wash (care) liquid, cream or lotion composition comprising: (a) 0.5 to 85% by wt. of a cleansing surfactant; (b) 0.1 to 10% by wt. of an optical modifying benefit agent; (c) 0.01 to 5% by wt. of a polymer having structure (-A-) i (-B-) j (-C-) k wherein co-monomer A is a cationic repeating unit possessing one or more cationic charge(s) when measured at pH 4 to 10; wherein co-monomer B is a water insoluble repeating unit comprising at least one hydrophobic portion which is part of the co-monomer backbone which hydrophobic portion is defined as comprising 3 to 20 C 1 to C 3 alkylene groups and from 1 to 3 C 1 to C 3 , alkyl groups and/or a pendant attached to the backbone such that equivalent alkane number of pendent group is >4 and wherein B is selected from the group consisting of n-dodecyl methacrylamide (DMA), n-(n-octadecylacrylamide) (ODA), n-tert-octylacrylamide (tOA) and mixtures thereof; wherein co-monomer C is a repeating unit selected to modify solubility of the overall polymer; wherein i, j, and k represent number of times each respective monomer is repeated in the polymer chain, with the proviso that ratio of j/i is from 0.01 to 0.4 and ratio of k/i is from 0.0 to 0.5; and wherein cationic charge density of co-monomer A is >3 meq/g; and/or charge density of entire polymer >2.
