Abstract

Although the ultrafine metal oxide particles with excellent UV-shielding effects are safer than organic UV-absorbing agents, the use of large quantities of the ultrafine metal oxide particles leads to make the feeling on the skin bad as well as to decrease its transparency. In order to solve these problems, previously, composite powders consisting of tabular or spherical powders coated with ultrafine metal oxide particles were developed. However, such coating with ultrafine metal oxide particles in large quantities deteriorates the comfort of use, while that with small quantities cannot provide the enough UV-shielding effects. Therefore, it has become necessary to develop novel inorganic cosmetic materials. In general, cerium dioxide shows a broad UV-shielding effect. In this study, we have developed an industrial fabrication method for petal-like, tabular, and spherical cerium dioxide particles. These morphologically controlled cerium dioxide particles showed specific slipping effects, UV-shielding effects, adhesion effects, cover effects, and shading-off effects depending on their morphology, which are useful for their applications in cosmetics. Moreover, by mixing petal-like, tabular, and spherical cerium dioxide particles in an appropriate ratio, a powdery foundation possessing synergistically integrated functions, such as a long-lasting effect, seamless fitting feeling, and beautiful finish of the makeup, could be obtained.
