The present invention relates to a sunscreen agent through hybridization of metal oxide nanoparticles, a preparation method thereof, and a cosmetic product using the sunscreen agent, and more particularly, metal oxide nanoparticles of titanium oxide (TiO 2 ) or zinc oxide (ZnO). Selected from aminopropyltriethoxy (methoxy) silane, glycidyltriethoxy (methoxy) silane, vinyltriethoxy (methoxy) silane, methyltrimethoxysilane and octyltriethoxysilane which are functional silanes; Any one or two or more kinds of silanes and ethylhexyl methoxycinnamate, octylmethoxycinnamate, phenylbenzimidazole sulfonic acid, avobenzone, oxybenzone, benzophenone, oxanilide, cinnamate, salicylate Organic or inorganic hybridization by combining one or two or more organic sunscreens selected from vinylamides and polymers of methacrylate monomers. Lead sunscreen, to a cosmetic preparation using the method and sunscreen. |
