Abstract
UV-absorbing compounds are disclosed that are derived from at least: (a) a UV absorber having at least one hydroxyl group, primary amine group, or secondary amine group, (b) a coupling agent having anhydride functionality, and (c) a graft host comprising an unsaturated fatty acid. These compounds absorb, scatter, deflect, or scatter ultraviolet radiation in a variety of personal care and performance chemical applications. R″ and R″′ are alkyl or alkenyl groups that naturally occur in oil.
