概要	Photoactive evaluation for cosmetic pigments in sunscreen agents, such as zinc oxide (ZnO), titanium dioxide (TiO2), aluminium oxide (Al2O3) and tungsten oxide (WO3), was carried out by examining DNA damage using agarose gel electrophoresis. Photoinduced DNA damage occurred in the presence of pigments under either aerated condition or oxygen gas atmosphere in the following order: WO3 = Al2O3 = rutile TiO2 << anatase TiO2 << TiO2 (P-25) << ZnO.
