In order to change the texture of the skin, we aim to achieve a matte finish by blending powders with strong light diffuse reflection, or to achieve a glossy finish by blending mica and plate-like pearl pigments.
In addition, in order to cover the dullness of the skin due to poor blood circulation and aging (the condition of the skin color in which the lightness and saturation of the skin color is reduced and the hue changes from red to yellow is called “dullness”).
It has been practiced to mix a pigment having high hiding power, such as titanium oxide or iron oxide, or mix a high-saturation organic pigment or lake pigment to add reddish color to change the skin color hue.
【0004】ここで、隠蔽力の高い顔料を用いた場合に
は、肌に厚ぼったく付着し肌の皺、たるみ等の形態トラ
ブルを目立たせると共に透明感が無く、不自然な仕上り
になり、これ等を解消するための課題を有している。[0004] When a pigment having a high hiding power is used, the pigment thickly adheres to the skin, and the morphological troubles such as wrinkles and sagging of the skin are conspicuous, and there is no transparency, resulting in an unnatural finish. To solve the problem.

させる結果にもなりそれを防ぐためには高度な美容技術
が必要であり、同様に課題が残されている。As described above, when the principle of complementary colors is used,
Although the hue can be covered, there is a problem that the skin color looks dull or the lightness or chroma of the decorative film is reduced due to the color-reducing and mixing action, and the application amount thereof (for example, the application amount of green, blue or purple). Incorrect) results in an increase in the dullness of the cosmetic film, and in order to prevent it, a high level of beauty technology is required.

う結果になり、この場合も課題を有している。On the other hand, mica and pearl pigments are blended in cosmetics in an amount necessary for imparting luster to the skin, and glossy powder (mica) and pearl pigments are applied to uneven portions and pores of the skin. When applied, the shading portion between the glossy powder and the pearl pigment and the uneven portion on the skin or the shaded portion of the pores, the pores and wrinkles are conspicuous, resulting in impairing the original makeup effect In this case, too, there is a problem.

なう欠点がある。In the conventional foundation, pigments having high covering power, that is, high refractive index (titanium oxide, red iron oxide, yellow iron oxide, black iron oxide, etc.) are used in order to cope with uneven skin color such as spots and freckles. Has been used to enhance the hiding power, hide uneven skin color, and correct it. However, although these highly opaque pigments are useful for concealing color unevenness, they have the drawback that they are thick and easy to adhere to the skin, resulting in thick makeup and conversely conspicuous wrinkles and pores. Inorganic pigments such as red iron oxide and other iron oxides originally have low brightness and saturation, and when wet with moisture or sebum, the brightness and saturation further decrease, causing the dulling phenomenon of the makeup film to progress, There is a disadvantage that the effect is lost.

がちである。On the other hand, in order to prevent uneven skin irregularities such as pores and fine wrinkles, various materials and cosmetics manufacturers have applied fine particles to the powder surface or coated the powder surface with a polymer or oxide. Different types of powder have been proposed. In order to make these irregularities less visible, a method of making irregularities less visible by increasing the irregular reflection of light on the powder surface has been adopted. According to such a method, in order to form an opaque and artificial makeup film on the skin, it is difficult to see uneven color and unevenness, and although a matte feeling as a change in texture can be obtained, it becomes white, It lacks the sense of unity with the skin, and tends to lose the skin's original clarity and bare skin.

有するものが求められている。Under the circumstances described above, there is an effect of preventing dullness of the decorative film, hiding the unevenness of color, and unevenness of the finish having a transparent feeling and a bare skin feeling to make the skin uniform. There is a need for cosmetics. Similarly, in the field of paints, there is a demand for a material having high chroma and high chroma, in which the underlayer is hardly seen even with a thin coating film.

【課題を解決するための手段】本発明者等は、前記課題
を解決し、目的達成に向けて鋭意検討すべく、従来の化
粧料粉体について下記の様な考察を行った。Means for Solving the Problems The present inventors have made the following considerations on conventional cosmetic powders in order to solve the above-mentioned problems and intensively study for achieving the object.

方法は加色混合の原理、即ち光を利用して混色により課
題解決を試みた。1. Conventional makeup cosmetics have no transparency, and as one of the causes that the cosmetic film becomes dull,
When adjusting the color tone (hue) of the external appearance color of make-up cosmetics
It was confirmed that the greater the number of types of pigments used, the lower the lightness and saturation and approached gray or black achromatic colors.
Further, iron oxide is generally used as a colored inorganic pigment used in makeup cosmetics, and the pigment itself has a color tone lacking in vividness. It was also confirmed that the more the wetting of the pigment with moisture and sebum progresses, the more the dull phenomenon accelerates. This time, we tried to solve the problem by using the principle of additive color mixing, that is, color mixing using light.

と、ぼかしてしまえば色むらや凹凸むらの見え方が大き
く変化することが予測できる。2. The appearance of unevenness due to irregularities in color, such as spots and freckles on the skin, pores, small wrinkles, and the like is affected by the appearance of the boundary between the unevenness in color and unevenness. The sharper and more vivid the difference in color and brightness at the border is, the easier it is to see the difference in color and unevenness on the other hand, while the more the difference in color and brightness at the border is blurred and gradual, the harder to see . Such appearance is called "sharpness" in the field of research on visual information, and the lower the sharpness, the more difficult to see. In other words, it is considered that even if the transmittance of light to the decorative film itself formed on the skin remains high, it is possible to make this boundary part difficult to see clearly. In other words, if blurred, it can be predicted that the appearance of uneven color and uneven unevenness will change significantly.
【0015】3. 見え方と密接な関係にある鮮映性は

決を試みたものである。[0015] 3. It has been found that the sharpness, which is closely related to the appearance, is correlated with the ratio of the total transmitted light amount to the decorative film and the straight transmitted light amount contained therein. That is, when the amount of the total transmitted light is large, and among them, the amount of the straight transmitted light is large (in this case, the amount of the diffuse transmitted light is small). The transmitted light increases.), The sharpness decreases. Two more cases can be considered for the decorative film having low sharpness. One is a case where the amount of the total transmitted light is small, and the other is a case where the amount of the total transmitted light is large and the diffusion transmittance is high. Among them, in the present invention, an attempt was made to solve the problem using the latter concept.

た。Based on the above considerations, the present inventors have simultaneously satisfied the conflicting make-up effects of preventing dullness of the decorative film, hiding the color unevenness and unevenness along with the finish having transparency and bare skin and uniforming the skin. As a result of intensive studies to solve specific issues to develop powders suitable for cosmetics to be developed,
At least a light-transmitting inorganic substance powder having a low refractive index having a specific shape and a coating of an inorganic substance having a geometric thickness that has a larger refractive index on the outer side than the powder and has a geometrical thickness. The present inventors have found that a composite functional powder obtained by configuring a high light diffusion transmittance can achieve the above object.
【0017】尚、「幾何学的厚さ」とはその厚さにより

できる。Further, when an oxide such as titanium oxide is used as a component of the coating, the surface is reduced to a lower oxide such as lower titanium oxide by reducing or the like.
Alternatively, a tint component such as various iron oxides may be added to a lower portion (lower surface or the like) or an upper portion (surface or the like) of the coating to develop a more favorable color tone by a cooperative action with the interference light.

Is low, the underlayer cannot be seen at all, as in the case of applying a paint that covers the surface. When the transparency (total transmittance) is high and the diffusion transmittance is high, as in the case of viewing through a ground glass, the color of the base is well understood, but the contour of the color unevenness and unevenness of the base is difficult to see without being clearly defined.
In other words, by forming a cosmetic film having high transparency and high diffusion permeability, unlike a cosmetic film using conventional powders and pigments, it is difficult to see color unevenness and unevenness, and light is transmitted from under the decorative film. It is considered that since the skin information is not lost, the transparency of the skin is maintained, and a cosmetic finish with a high bare skin feeling can be achieved.
