    Notes: Because of the low refractive indices, plate-like cerium phosphates (CePs) are expected tobe used as one of active ingredients in personal suncare cosmetics. Plate-like Ce2(PO4)2HPO4・H2Oparticles were synthesized via solvothermal reactions of Ce(NH4)2(NO3)6 or Ce(SO4)2・4H2O inphosphoric acid with or without nitric acid and sulfuric acid solutions. The variation of morphologyof Ce2(PO4)2HPO4・H2O particles significantly depended on the variety of cerium salt, isothermaltemperature and time, although all reaction products consisted of plate-like particles. This plate-likecompound showed excellent UV light absorption and transparency in the visible light region.Consequently, it is suggested that the plate-like Ce2(PO4)2HPO4・H2O particles might be used assuncare products to give an ideal optical effect of both UV-shielding ability and transparency in thevisible light region, as well as a good feeling on the skin
