Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an external preparation for skin which changes the sense of skin hue to a natural skin color.

[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. On the other hand, in order to hide the reddish face and red acne scars, use pigments that have green transmission light, which is a complementary color of red, or use blue or purple pigments to give a sense of transparency, to enhance the sense of skin hue. Changes are being made.

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.

Therefore, a skin cosmetic containing a powder having a color difference (ΔE) of 7 to 40 determined from two interference colors measured under specific conditions has been proposed (Japanese Patent Application Laid-Open No. H10-19491).
No. 2). According to this, a powder having a color difference (ΔE) in the above-mentioned range is generated by utilizing the principle of additive color mixture, and a surface interference color that can be observed at a wide range of angles is used to make the skin hue clear while giving a sense of transparency. You can change your senses.

[0005]

However, when the above-mentioned skin cosmetic is applied to the skin having moles, dark spots, whiskers, shaving marks on the waste hairs of the armpits (hereinafter referred to as dark areas), the dark areas appear. Since the surface interference color of (1) is more intense than the surface interference color of the surrounding skin, the interference color tends to be more conspicuous in darker portions, resulting in an unnatural hue.
Therefore, an object of the present invention is to provide a skin external preparation that changes the hue sensation of a skin having a dark color portion to a natural and uniform skin color.

[0006]

Alternatively, the color difference (ΔE) can be obtained from the above equation. What
The black synthetic leather used for such measurement is
Color difference (ΔE) obtained in the same way when the body is uncoated
Is 7 or less.

The powder 1 used in the present invention has a color difference (ΔE) of 7 to 40 determined in this way. 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 powder 1 is a powder having an average particle diameter represented by a median diameter (hereinafter referred to as an average particle diameter) of 2 to 12 μm. The powder 1 having an average particle diameter in this range has a good feeling in use and can reduce a glare like a mirror surface, and a powder of 5 to 12 μm is particularly preferable.

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, as the metal oxide, for example, titanium oxide,

Is suitable for concealing dark areas of the skin and is preferable because the skin looks healthy. In order for the interference color to show a yellow to red system, when the metal oxide is titanium oxide, 20 to 12
What is necessary is just to coat with an optical film thickness of 0 nm. When other metal oxides are used, 20-120 nm in titanium oxide
(This depends on the refractive index of the material). A coating having a predetermined optical thickness may be provided on a single mother powder with two or more layers, for example, with a transparent film interposed between layers.

By combining two or more kinds of powders and mixing them into powder 1, it is possible to produce an appropriate color tone, for example, the above-mentioned yellow-red interference color. When powder 1 is obtained by combining two or more powders, powder 1 after uniform mixing has a ΔE of 7 to 40 and an average particle diameter of 2 to 12 μm.

In addition, when the external preparation for skin of the present invention is applied to the skin that is not completely dark but is entirely dark and dull, the white skin of the powder 2 makes the whole skin close to white. Since the intensity of the interference color is reduced, a natural finish that does not give an impression that light is emitted from the skin is obtained.
