Аннотация:In spite of good sun protection characteristics, nanocrystalline TiO2 and ZnO widely used as inorganic UV filters can display a negative effect on skin. Nanocrystalline cerium dioxide was proposed as a promising component of sun protection cosmetics, however, no quantitative comparison of sun protection characteristics of CeO2 with other metal oxides was carried out until now. In this work, we experimentally determined for the first time the values of sun protection factor and UVA protection factor for CeO2 nanoparticles in accordance with the State Standard ISO 24443-2016 and compared them with characteristics of TiO2 and ZnO. Effect of size factor on CeO2 sun protection characteristics has been found.
