Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is capable of changing the hue of the skin while providing a sense of transparency, and covering uneven skin colors such as spots and freckles, and providing a natural and bare skin finish. It relates to the resulting skin cosmetic.

[0002]

2. Description of the Related Art Conventionally, make-up cosmetics have been applied to change the texture of the skin, so that a powder having a strong diffuse reflection is blended to obtain a matte finish, or a specular reflection such as mica is applied. The powder is blended to give a shiny finish. In addition, in order to cover the dullness of the skin due to poor blood circulation or aging (the skin becomes dark and yellow), pigments with high concealing power, such as titanium oxide and iron oxide, are blended. It has been practiced to change the hue of the skin by adding a red color such as.

[0003] On the other hand, in order to hide reddish faces and red acne marks,
It has been practiced to use a green pigment which is a complementary color of red, or use a blue or purple pigment to give a sense of transparency to change the hue of the skin.

[0004] However, when a pigment having a high hiding power is used, there is a problem that an unnatural finish is produced without a transparent feeling. In addition, when the principle of complementary colors is used, hue can be covered, but saturation is reduced, and on the contrary, skin color becomes dull. These problems arise because the method is a hue control based on subtractive color mixing.
The reason is that the saturation decreases and the color approaches gray. Thus, it has been difficult for conventional makeup cosmetics to change the skin hue sensation while imparting transparency.

[0005] Make-up cosmetics are also required to have a function of covering uneven skin color such as spots and freckles.
As a method corresponding to this, a pigment having a high hiding power, that is, a pigment having a large refractive index or a pigment having a high coloring power, such as titanium dioxide, red iron oxide, yellow iron oxide, black iron oxide, or an organic dye, is blended as a coloring pigment. In addition, a method has been adopted in which the cover power is increased, thereby making it difficult to see uneven color such as spots and freckles existing on the skin.

However, when a large amount of a pigment having a high hiding power as described above, that is, a pigment having a large refractive index or a pigment having a high coloring power is added, a thick cosmetic feeling is exhibited, the color becomes opaque, and a natural feeling is lost. There is a disadvantage that.

On the other hand, in order to impart a sense of transparency and bare skin to the makeup skin, pigments having a small refractive index, such as talc, kaolin, and mica, have conventionally been blended as extender pigments. These pigments have been used in large amounts because of their superior usability such as spreading and sticking compared to the coloring pigments described above. However, it has a drawback that when applied to the skin, there is a tendency that it tends to give a glimpse to the appearance and give an unnatural luster.

[0008]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a method that does not change the color depending on the observation direction, can change the hue of the skin while giving a sense of transparency, and is capable of changing the hue of the skin such as spots and freckles. An object of the present invention is to provide a skin cosmetic which covers color unevenness and can obtain a natural finish.

[0009]

Under such circumstances, the present inventors have conducted intensive studies and found that conventional makeup cosmetics do not have a sense of transparency and the skin color is dull because the hue control method is a subtractive method. Because it is based on color mixing, I came to realize that the more colors overlap, the lower the saturation and the closer to gray, and the principle of additive color mixing, that is, color mixing using light I thought that this would solve this problem. When the powder (A) having a specific color difference and the inorganic powder (B) having a specific optical property are used in combination, the hue of the skin can be changed while giving a sense of transparency, -It has been found that a skin cosmetic having a natural and bare skin finish can be obtained, which covers uneven skin color such as freckles, and has completed the present invention.

That is, the present invention provides the following component (A) and
(B) (A): 8 mg / 100 cm of powder on black synthetic leather^TwoAverage

To provide.

Conventionally, pearl powder has been blended into foundations and the like, but in this case,
The pearly luster gives a glaring feeling, resulting in a poor finish, or the pearly feeling and the color tone due to interference may change depending on the observation angle. This is because in the conventionally used pearl powder, the interference color has directionality with respect to the incident angle of light, is strongly developed near regular reflection, and is hardly observed in other directions.

On the other hand, the powder of the component (A) used in the present invention has a small change in color tone depending on the observation angle, that is, the interference color can be observed not only in the vicinity of specular reflection but also in a wide range. Things.

[0013]

BEST MODE FOR CARRYING OUT THE INVENTION In order to determine the color difference (ΔE) of the powder of the component (A) used in the present invention, first, 8 mg / 100 cm ^{2 of the} powder is put on black synthetic leather and the sponge is used. And apply evenly by rubbing lightly. For example, using a goniospectrometer (Murakami Color Research Laboratory, G
Using CMS-3), incident light angle 45 °, light receiving angle -45 °
And -20 °. The two interference colors at this time are C
Defined in IE1976L ^* a ^* b ^* color system, incident light angle 45
° and the light receiving angle −45 ° (L _45,45 ^* , a ₄₅ , ₄₅ ^* , b
_{45 , 45} ^* ), the incident light angle of 45 ° and the light receiving angle of −20 ° are (L _45,20 ^* , a _45,20 ^* , b _{45 , 20} ^* ), and using these, ΔE is calculated from the above equation. You can ask. The black synthetic leather used for such a measurement has a ΔE of 7 or less, which is similarly obtained.

The powder of component (A) has a ΔE of 7 to 40, preferably 10 to 35, thus obtained. If it is less than 7, the hue of the skin will change but the transparency will be lost. If it exceeds 40, the hue will change greatly depending on the angle at which the skin is viewed, resulting in a sense of discomfort.

The particle size of the powder of component (A) is not particularly limited, but those having an average particle size of 12 μm or less, especially 5 to 12 μm, are preferable because they provide good feeling in use and reduce glare. .

These can be used alone or in combination of two or more, and titanium oxide, iron oxide, or a mixture thereof is particularly preferable. When coating is performed using a mixture of titanium oxide and iron oxide, the titanium oxide is preferably rutile and does not contain tin. In addition, the method of coating the base powder with the metal oxide particles is not particularly limited, and can be performed according to an ordinary method.

Further, by controlling the optical thickness of the metal oxide particles covering the surface of the base powder, various color tones can be produced. And, for example, a powder whose interference color shows a blue to purple color gives a sense of transparency to the skin,
Powders whose interference color is green do not become dull, suppresses redness of the skin, and powders whose interference color shows orange to red make the skin look healthy and hide the dull skin Becomes possible.

Further, by using two or more powders in combination as the component (A), it is possible to produce various color tones. When two or more powders are used in combination, it is preferable that the ΔE of the powder after mixing is 7 to 40.

The surface of the powder of the component (A) is preferably subjected to a hydrophobic treatment from the viewpoint of light resistance.
