Photoprotective/cosmetic compositions comprising sulfonamido-functional polyorganosiloxanes/polyorganosilanes

摘要

Topically applicable sunscreen/cosmetic compositions well suited for enhanced photoprotection of human skin and/or hair against the damaging effects of UV-A and UV-B irradiation, particularly solar radiation, comprise a photoprotecting effective amount of a novel sulfonamido-functional polyorganosiloxane/polyorganosilane having one of the formulae (1) to (3): wherein A is a monovalent benzylidenecamphor radical which comprises a sulfonamido-functional bridging group, which is bonded directly to a silicon atom, and which has the formula.
