Description

  The present invention relates to a cosmetic material that is transparent, has a bright and natural finish, and has an excellent effect of improving the skin color dullness of the bare skin and making it a healthy skin color.

  In conventional cosmetics such as makeup cosmetics, titanium oxide and iron oxide are used to cover the dullness of the skin color that is felt with aging due to poor blood circulation and pigmentation (a state in which lightness decreases and yellow saturation increases). The skin tone is changed by adding pigments with high hiding power, such as red pigments such as Bengala, lake pigments and organic pigments, and in some cases pigments such as blue and green ( Patent Document 1).

  However, when a pigment with high hiding power is used, it sometimes gives an unnatural impression, and when a colored pigment is used, it is a color that deviates significantly from the skin color area, so An unnatural impression was given. In addition, a sufficient amount of white pigment is required to give appropriate brightness to the makeup skin, but on the other hand, it enhances the makeup feeling and causes whitening.

Thus, with conventional makeup cosmetics, it has been difficult to improve the dull skin color by naturally changing the hue of the skin.

The powder of the component (A) used in the present invention has a cosmetic skin color ΔL ^* and Δb ^* determined in accordance with the above formulas of ΔL ^* > 0 and Δb ^* <0, respectively. Here, in order to obtain these values, first, the surface of the base made of artificial skin like skin or skin before applying the powder, for example, a spectrocolorimeter (manufactured by Minolta Co., Ltd., CM-1000). Use to measure color. Next, the powder is taken on the ground, and is applied uniformly to 8 mg / 100 cm ² by lightly rubbing with a sponge, and this is similarly measured. The two colorimetric values obtained at this time are defined in the CIE 1976 L ^* a ^* b ^* color system, the one before coating (L ₀ ^* , a ₀ ^* , b ₀ ^* ) and the one after coating (L ₁ ^* , A ₁ ^* , b ₁ ^* ), and using these, ΔL ^* and Δb ^* can be obtained from the above equations. In addition, the skin or skin-like artificial leather used for such measurement has the colorimetric values of L ^* = 45 to 85, a ^* = 0 to 30, and b ^* = 0 to 30, particularly L. ^* = 55 to 75, a ^* = 5 to 15, and b ^* = 15 to 25 are preferable.
