Fabrication and Characterization of Cosmetic-grade TiO<sub>2</sub>@SiO<sub>2</sub> for UV-shielding Ingredient
Wenrong Xiang Rui Liu Jiesong Liu Chengxue Du Li Li<p>Nanoscale TiO<sub>2</sub> generates reactive oxygen species (ROS) under ultraviolet (UV) radiation, causing damage to biological systems and polymers. To mitigate associated health risks in cosmetic applications, TiO<sub>2</sub> core-shell materials were synthesized. This study describes the fabrication of TiO<sub>2</sub>@SiO<sub>2</sub> core-shell materials utilizing a chemical deposition technique with nanoscale TiO<sub>2</sub> and sodium silicate (Na<sub>2</sub>SiO<sub>2</sub>) as precursors. The outcomes demonstrated that the morphology, configuration, and light-interacting properties of the surface-coated SiO<sub>2</sub> shell are governed by the solution's pH value. Under alkaline conditions, it can obtain a uniform and dense continuous SiO<sub>2</sub> shell layer, which not only improves the whiteness and brightness of TiO<sub>2</sub> but also reduces oil absorption. The TiO<sub>2</sub>@SiO<sub>2</sub>-10 sample exhibited a sun protection factor (SPF) of 41 ± 2, suggesting potential for cosmetic-grade UV filters. Process simplicity further supports practical applicability.</p>
