Abstract: Coated powder is obtained by applying a material having a refractive index of 1.9 to 3.1 to powder having a refractive index of 1.3 to 1.8 as a core and further applying a material having a refractive index of 1.3 to 1.8 to the coated core. When this powder is used for cosmetics or paints, natural coloring can be accomplished without deteriorating lightness because a screening effect is not high.

Abstract: A make-up cosmetic product, which enhances the appearance of complexion, is evaluated by irradiating lights having a wavelength range of visible light onto a surface on which the make-up cosmetic product is applied, from at least two directions with different incident angles, measuring a plurality of spectra of reflected lights obtained from the irradiated lights, respectively, and comparing the spectrum patterns with each other. This clarifies the optical theory by which the skin looks beautiful and provides a method for evaluating a make-up cosmetic product making the skin look beautiful.

Abstract: Disclosed are a make-up cosmetic product containing, as a film-forming agent, a copolymer with a mean molecular weight of from 10,000 to 1,000,000, as prepared by copolymerizing an acrylate and a polymerizing carboxylic acid at a determined ratio or by copolymerizing an acrylate, at least one selected from vinyl acetate, methyl methacrylate and acrylamide and a polymerizing carboxylic acid at a determined ratio; and a double-coat type make-up cosmetic product comprising, a combination of an under make-up base for a first layer containing as a main component an adhesive film-forming agent such as said copolymer and a finishing make-up material for a second layer containing as a main component an aluminum powder.
