NANOSTRUCTURED SUN PROTECTION AGENT AND PROCESS |
摘要 |
A system comprising of core-shell-type nanoparticles is described, the shell consisting of oxide nanoparticles and the core consisting of polymers and solar radiation protection chemicals, said system providing broad-spectrum solar protection, ranging from UVA to UVB, due to the chemical composition thereof which comprises physical protection agents, oxide nanoparticles and nanoencapsulated chemical protection agents within the polymeric matrix. Due to the size scale, composition and morphology of said prepared nanoparticles, these can be used in cosmetic formulations, in preparing sun screens, or in any other formulation mainly intended to provide solar radiation protection. |
