Silicone polymers containing UV photostabilizing groups |
摘要 |
The present invention is directed to a series of silicone containing polymers that contain photostabilizers that act as photo stabilizers for Ultra Violet radiation. The polymers of the present invention are multi functional sun screening additives that allow in addition to photostabilizing the active sunscreen agent found in sunscreens, additionally provide high levels of UV protection in a cosmetically elegant base. The compounds are made by the reaction of a benzatriazole compound and a methyl ester silicone compound. |
