Abstract
A dispersion which has a stable dispersibility, that is, a dispersion in which an ultraviolet light scattering agent is dispersed homogeneously and with good stability for a prolonged time with a dispersant, and a cosmetic in which such a dispersion is blended and which is superior in emulsion stability. There is provided a dispersion that has an extremely stable dispersibility, in which, by blending an ultraviolet light scattering agent coated with an inorganic oxide, aggregation of the coated ultraviolet light scattering agent is suppressed. There is also provided a cosmetic which, through use of an ultraviolet light scattering agent coated with the inorganic oxide and dispersant, or through use of the above dispersion, has a higher effect of ultraviolet light protection with an emulsion stability superior to that of a conventional product, as well as an improved use of feeling and safety.
