    Abstract

    Fine powder of calcia-doped ceria (Ce0.8Ca0.2O 1.8) is of potential interest as an UV radiation blocking material in personal care products because of the excellent UV light absorption ability, natural appearance on the skin and low photocatalytic activity. However, the comfort of nanoparticles when applied on the skin is modest because of the agglomeration. In order to attain further performance improvements concerning UV-shielding, calcia-doped ceria nanoparticles were coated on plate-like potassium lithium titanate (K0.8Li0.27Ti 1.73O4), 10-20 μm in diameter via solution processes. Such panoscopic assembling successfully improved the comfort of the product when wearing it on the skin without compromising the UV-shielding ability, meanwhile greatly reducing the oxidation catalytic activity.
