[0002]

2. Description of the Related Art Conventionally, make-up cosmetics have pigments having high hiding power, such as titanium oxide and iron oxide, in order to cover dullness of the skin due to poor blood circulation and aging (skin becomes dark and yellow). Or the addition of red color such as redwood, lake pigments and organic pigments to change the skin hue sensation. It is also possible to change the skin hue sensation by using a green pigment, which is a complementary color of red, to hide reddish faces and red acne marks, or by using blue or purple pigments to give transparency. Is being done.

However, when a pigment having a high hiding power is used, natural feeling disappears, and when the principle of complementary color is used, hue can be covered but saturation is lowered, and on the contrary, skin color becomes dull. Problem. In addition, cosmetics such as make-up cosmetics are also required to hide color unevenness such as spots and freckles present on the skin, but it is necessary to cover such color unevenness, I couldn't be satisfied with the reproduction of a typical flesh color at the same time.

As described above, it has been difficult to change the hue sensation of the skin or to obtain a desired skin color while giving a sense of transparency.

BEST MODE FOR CARRYING OUT THE INVENTION The powder of the component (A) used in the present invention has a color difference (ΔE) determined according to the above equation of 7 to 40.
belongs to. Here, in order to obtain the color difference, first, powder is applied to black synthetic leather so as to have a concentration of 8 mg / 100 cm ^2, and is evenly applied to the synthetic leather using a sponge so as to be lightly rubbed. The color is measured at, for example, an incident angle of 45 °, a light-receiving angle of −45 °, and −20 ° using a goniospectrophotometer (GCMS-3, manufactured by Murakami Color Research Laboratory). The two interference colors at this time are defined by the CIE1976 L ^* a ^* b ^* color system, and when the incident angle is 45 ° and the light receiving angle is −45 °, (L _45,45 ^* , a _45,45 ^* , b _{45 , 45} ^* ), when the incident angle is 45 ° and the receiving angle is −20 °, (L _45,20 ^* , a _45,20 ^* ,
b _{45,2 0} ^*) and then, using these color difference from the equation (delta
E). The black synthetic leather used for such a measurement has a color difference (ΔE) of 7 or less similarly obtained.

The powder of the component (A) has a color difference (ΔE) thus determined of 7 to 40, preferably 10 to 35.
belongs to. If it is less than 7, the hue sensation of the skin changes, but the transparency is lost. If it exceeds 40, the hue sensation greatly changes depending on the angle at which the skin is viewed, and a sense of discomfort occurs.

The particle size of the powder having such a color difference (ΔE) is not particularly limited, but the average particle size is 12 μm or less, particularly 5 to 5 μm.
Those having a size of 12 μm are preferable because they have a good feeling in use and can reduce glare.

The powder preferably emits an interference color when coated with metal oxide particles. Here, examples of the mother powder to be coated include mica, platy titanium oxide, platy iron oxide, platy alumina, platy silica, fish scale foil, bismuth oxychloride, and the like, with mica being particularly preferred.

Further, by controlling the optical thickness of the metal oxide particles covering the surface of the base powder, various color tones can be produced. For example, a powder having an interference color of blue to purple gives a transparent feeling to the skin, and a powder having an interference color of green does not become dull, suppresses the redness of the skin, and the interference color becomes orange to A powder showing a reddish color can make the skin look healthy and hide the dullness of the skin. Further, by using two or more kinds of powders in combination, it is possible to produce various color tones. In this case, it is preferable that ΔE of the powder after mixing is 7 to 40.
