Powdery-type foundation, one of the typical makeup cosmetics, is required to form even and smooth powdered layer on the skin. Such layer is achieved by well-dispersion of foundation particles. However, particles of titanium-dioxide and iron-oxide, both of which are vital foundation components, easily aggregate on the skin. In order to solve this problem, this study aimed to develop novel low-aggregation titanium-iron oxide particle. Experiments showed that our developed particle, in which titanium dioxide is coated with iron oxide, achieved well-dispersion due to its unique structure and shape. The experiments also showed that such a particle property results in an effective coverage of color-unevenness and pores of the facial skin.
