Fe oxide-coated TiO2 particles for UV protection cosmetics were produced by means of atmospheric pressure glow discharge using IAA(Iron acethyl acetonato). The particles were also coated by a silica protection layer. To examine the UV catalytic ability of Fe oxide -coated TiO2, we measured a squalene that contained the powders by GCMS for the gas products after the squalene had been irradiated by a Xe lamp for one hour. Using silica-coated TiO2 that was coated by Fe oxide, we find almost no signals from any harmful organic oxides in the GC-MS spectra of the UV irradiated squalene. The multi- coated powder shows very fine and flesh like-color with pearl-like glowing.
