Bodily exposure to ultraviolet (UV) ray irradiaction has drawn increased attention, particularly in its relationship to skin cancer. UV shielding materials has thus been widely studied. We investigated the how to prepare TiO₂ particles as UVA shielding. By adjusting the seed amount during hydrolysis, we prepared a technique for anatase TiO₂ powders whose transmittancy curve in the UVA and UVB regions is almost the same as that of commercially available rutile TiO₂. Anatase TiO₂ powders exhibited superior UV shielding. We experimentally reified the appropriateness of the simulation proposed by Stamatakis et al. for suitable-size particle, demonstrating the satisfactory coincidence of UVA shielding with minimum percent-transmission micell. Generally, TiO₂ powders superior for UVA shielding shows poor transparency over the visible wavelength range. Excessive grinding of powders lowered UV shielding, while slightly imposing visible transparency range.
