Patent ID: 8349780

Claim:
A personal care composition comprising: (a) an active material having one or more functional groups capable of covalent attachment in the presence of an acid or a base to one or more complementary functional groups; wherein the active material is selected from the group consisting of Bis-Hydroxyethoxypropyl Dimethicone, and a silicone copolymer from monomers which contain organic alcohol groups having the structure: R1-[Si(CH2)(R3-CH20H)—O] n -[Si(CH2)2-O] m -R2 wherein R1 and R2 are methyl; and R3 is CH2CH2CH2-(OCH2CH2O)q-H with q≧1; and (b) a photocatalyst capable of generating an acid or a base upon exposure to light; wherein said photocatalyst is a photoacid or photobase selected from the group consisting of aromatic hydroxyl compounds, sulfonated pyrene compounds, onium salts, diazomethane derivatives, bis-sulfone derivatives, disulfuno derivatives, nitrobenzyl sulfonate derivatives, sulfonic acid ester derivatives, sulfonic acid esters of N-hydroxyimides, and combinations thereof wherein the light absorbed by the photocatalyst is selected from the group consisting of ultraviolet light, visible light, and combinations thereof and (c) a physiological acceptable vehicle for dispersing or dissolving the active material and the photocatalyst for application of the composition to a substrate; and wherein the vehicle is a physiological acceptable vehicle and the substrate is selected from the group consisting of hair, skin, nail, teeth and combinations thereof.
