SiO₂‒TiO₂ binary aerogels obtained by the methods of low-temperature (carbon dioxide) and high-temperature (isopropanol, hexafluoroisopropanol and methyl tert-butyl ether) supercritical drying are considered as multifunctional cosmetic pigments with high anti-shine power and photoprotective properties. The composition and structure of SiO₂–TiO₂ aerogels obtained by supercritical drying in various fluids were studied by IR spectroscopy, X-ray diffraction, energy dispersive X-ray spectroscopy, scanning and transmission electron microscopy, and low-temperature nitrogen adsorption. The values of the sun protection factors SPF and UVAPF for the obtained materials are comparable to those of the commercial sunscreens Kronos 1171 and Kronos 2971, and the anti-shine power is approximately 1.5 times higher than that of kaolin-based materials.

通过低温（二氧化碳）和高温（异丙醇，六氟异丙醇和甲基叔丁基醚）方法获得的SiO ₂ ‒TiO ₂二元气凝胶被认为是具有高光泽度和光保护性的多功能化妆品颜料。属性。SiO ₂ -TiO ₂的组成和结构通过红外光谱，X射线衍射，能量色散X射线光谱，扫描和透射电子显微镜以及低温氮吸附研究了在各种流体中超临界干燥得到的气凝胶。所得材料的防晒系数SPF和UVAPF的值可与市售防晒剂Kronos 1171和Kronos 2971的值相比较，并且抗发亮能力比基于高岭土的材料高约1.5倍。
