COSMETIC FORMULATIONS COMPRISING ZnO NANOPARTICLES |
摘要 |
The present invention relates to the formation of surface treated zinc oxide and titania particles, and in particular zinc oxide and titania nanoparticles, with a siloxane star-graft copolymer coating, comprising a looped and/or linear polymeric structure on a star-graft copolymer coating, on a particle surface to control the interfacial surface interactions between the particle and the oil phase of the cosmetic skin formulation.
