Synthesis and characterization of plate-like ceria particles for cosmetic application

Plate-like cerium oxide particles were successfully prepared by a facile precipitation process of cerium carbonate precursor followed by calcination in air at 400 °C. Ceria particles with the same morphology and slightly decreased particle size compare with those of plate-like cerium carbonate precursor were obtained. The particle size could be controlled by precisely adjusting pH value of the solution. In comparison with commercial ceria nanoparticles, the synthesized plate-like ceria particles showed lower oxidation catalytic activity, higher comfort of use and higher gloss value as well as excellent UV-shielding ability, indicating the potential application as a new cosmetic agent.
