Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a skin cosmetic which can change the sense of hue of skin while having a transparent feeling.

[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 circulation or aging (the skin becomes dark and yellow), pigments with high concealing power such as titanium oxide and iron oxide are blended, and red pigments, lake pigments and organic pigments are added. It has been practiced to change the skin hue sensation 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.

However, when a pigment having a high hiding power is used, there is a problem that the natural feeling is lost. 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 occur because the method is a hue control based on subtractive color mixture, and the more the colors are superimposed, the lower the saturation and the closer to gray.

As described above, it is difficult for conventional makeup cosmetics to change the skin hue sensation while providing transparency.

[0006]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a skin cosmetic which has no change in color depending on the observation direction and can change the hue of the skin while giving a sense of transparency. .

[0007]

Under such circumstances, the present inventors have conducted intensive studies and as a result, have found that the principle of additive color mixing, that is, color mixing using light, is not the principle of subtractive color mixing conventionally used. By using a powder having a specific color difference (ΔE), a skin cosmetic that can change the skin hue sensation while giving a transparent feeling by the surface interference color generated by the powder is used. The inventors have found that the present invention can be obtained, and completed the present invention.

That is, according to the present invention, powder is uniformly applied to black synthetic leather at 8 mg / 100 cm ² , and this is applied to an incident light angle of 4 mg / 100 cm ^2.
When measured at 5 °, receiving angles of -45 ° and -20 °, C

Conventionally, pearl powder has been blended into foundations and the like, but in this case,
A pearly unique glossy feeling and a glaring feeling are produced, resulting in a poor finished feeling, and the pearly feeling and the color tone due to interference may change depending on the observation angle. This is because conventionally used pearl powder is
This is because the interference color is directional with respect to the incident angle of light, is strongly developed near regular reflection, and is hardly observable in other directions. On the other hand, the powder used in the present invention has a small change in color tone depending on the observation angle, that is, it can observe interference colors not only in the vicinity of specular reflection but also in a wide range.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION The powder used in the present invention has a color difference (ΔE) of 7 to 40 determined according to the above equation. Here, in order to obtain the color difference, first, 8 mg / 100 cm ^{2 of} powder is taken on black synthetic leather, and the powder is evenly applied to the synthetic leather using a sponge so as to be lightly rubbed. this,
For example, a goniospectrometer (Murakami Color Research Laboratory,
GCMS-3), incident light angle 45 °, light receiving angle −45
Measure color at ° and -20 °. The two interference colors at this time are defined by the CIE1976L ^* a ^* b ^* color system, and the incident light angle 4
When 5 ° and the receiving angle are −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 ^* ). (ΔE) can be obtained. The black synthetic leather used for such a measurement has a color difference (ΔE) of 7 or less, which is similarly obtained.

The powder used in the present invention has a color difference (ΔE) determined in this manner of 7 to 40, preferably 10 to 3
Five. 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, especially 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.

It is preferable that the powder emits an interference color when coated with metal oxide particles. Here, as the base powder to be coated, for example, mica, plate-like titanium oxide, plate-like iron oxide, plate-like alumina, plate-like silica, fish scale foil,

Among such powders, powders obtained by coating the surface of mica with a metal oxide, in particular, titanium oxide, iron oxide or a mixture thereof are preferred. The method for coating the base powder with the metal oxide particles is not particularly limited, and may be performed according to a usual 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 kinds of powders in combination, 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 powder used in the present invention is preferably subjected to a hydrophobic treatment on the surface in view of light resistance. In addition, ΔE may change due to the hydrophobic treatment,
