摘要

Method for protecting human skin or human hair from ultraviolet radiation, for personal care formulation containing sunscreen to protect human skin or human hair from ultraviolet radiation, and partu00eccula treated in superfu00eccie.The present invention relates to the formation of particles of zinc oxide and titania is treated on the surface and, in particular, the nanoparticles of zinc oxide and titania, with a coating of a copolymer of siloxane star graft, comprising a polymer structure in the loop and / Or linear in a coating of a copolymer of the graft star, on a surface of the particles.To control the interactions of interfacial surface between the particle and the oil phase of formulation of skin cosmetics.
