Patent ID: 7244420

Claim:
A cosmetic composition comprising, in a cosmetically acceptable medium, at least 0.02% by weight, relative to the total weight of the composition, of at least one substantially unpolymerized, water-soluble, organosilicon compound, the organosilicon compound being: a silane having one silicon atom having the formula: in which: R′ represents a halogen or an OR 1 group; R″ represents a halogen or an OR 2 group; R 1 and R 2 represent, independently of each other, hydrogen or C 1 -C 12 alkyl, C 6 -C 14 aryl, (C 1 -C 8 alkyl)(C 6 -C 14 aryl) or (C 6 -C 14 aryl)(C 1 -C 8 alkyl) group; R 3 is a nonhydrolyzable functional group with a cosmetic effect that is a coloring, or reducing effect; and R 4 is a nonhydrolyzable functional group with a solubilizing function; or a siloxane having two or three silicon atoms and having at least two hydroxyl or hydrolyzable groups and at least two nonhydrolyzable functional groups per molecule, at least one of the nonhydrolyzable functional groups being a group with a cosmetic effect that is a coloring, UV-stabilizing, antibacterial, antifungal or reducing effect, and at least one of the other nonhydrolyzable functional groups being a group with a solubilizing function.
