Nanosized TiO2 is used extensively in sunscreen cosmetics as an inorganic UV absorber that can allow an optically transparent film to be applied to human skin. TiO2 is known to exist in three crystal forms: anatase, brookite and rutile. The rutile phase is generally used as a component in sunscreen cosmetics because of its higher UV absorption. A surface coating can be added to nanosized TiO2 to enhance its UV absorption by a different light diffraction mechanism. Silica‐coated nanosized TiO2…

Preparation of TiO2 Nanocrystallite Powders Coated with 9 mol% ZnO for Cosmetic Applications in Sunscreens

The analyses of UV/VIS/NIR spectra reveal that the absorption of the T-9Z precursor powders after being calcined has a red-shift effect in the UV range with increasing calcination temperature, therefore, the TiO2 nanocrystallite powders coated with 9 mol% ZnO can be used as the attenuate agent in theUV-A region for cosmetic applications in sunscreens.
