    • The object of the invention is to provide a colorant composition for skin cosmetics, that can provide a natural texture while retaining hiding power, a foundation containing the same, and a method of makeup application. A colorant composition for skin cosmetics of the present invention is characterized in that the colorant composition, which contains nonwhite coloring materials, does not contain a high refractive index white pigment, and when the spectral reflectance of the colorant composition is measured under the below-described measurement conditions, the minimum spectral reflectance on the white ground in the wavelength range of 630-700 nm is 75% or higher, and the Y value on the white ground is in the range of 25-65 (Measurement conditions) A colorant composition is dispersed in nitrocellulose lacquer, the concentration of the colorant composition is adjusted so that the spectral reflectance on the white ground of a black and white hiding test paper at the wavelength of 400 nm is 10±2%, a black and white hiding test paper is coated with an applicator having a 0.101 mm clearance, and the spectral reflectance is measured with a spectrocolorimeter.
    • 本发明的目的是提供一种皮肤化妆品的着色剂组合物,其可以提供天然质地,同时保持遮盖力,含有该着色剂的基础,以及化妆方法。 本发明的皮肤化妆品用着色剂组合物的特征在于,含有非白色着色材料的着色剂组合物不含高折射率白色颜料,并且当在下述条件下测定着色剂组合物的光谱反射率时 测量条件下,白色地面上在630-700nm波长范围内的最小光谱反射率为75%以上,白色地面上的Y值在25-65的范围内(测量条件)着色剂组成为 分散在硝酸纤维素漆中,调节着色剂组合物的浓度,使得在白色隐蔽试纸的白色掩蔽试纸的波长400nm处的光谱反射率为10±2%,黑白隐蔽试纸为 涂覆有具有0.101mm间隙的涂布器,并且用分光色度计测量光谱反射率。
