DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a makeup cosmetic containing hexagonal plate-shaped aluminum oxide and an organic powder and / or a glitter powder.
An object of the present invention is to provide a makeup cosmetic which has excellent finish characteristics such as an effect of imparting a natural luster to the skin and making small wrinkles less noticeable when applied to the skin, and a smooth application feeling.

[0002]

2. Description of the Related Art The quality characteristics required for makeup cosmetics include the provision of visual finish characteristics such as natural color, luster, three-dimensional feeling, and less noticeable wrinkles, and smoothness when using cosmetics. Use feeling such as elongation and sliding feeling, and continuity of the cosmetic effect over time, and the like can be given. Recently, among these quality characteristics, makeup cosmetics, which are particularly characterized by finished characteristics, have been well received in the market, and various techniques have been used. First, as a technique for imparting a glossy or three-dimensional appearance to the skin, there is a technique in which a brilliant powder such as mica having a large particle diameter or mica coated with titanium oxide is blended. Further, as a technique for making fine wrinkles less noticeable, a technique in which a light-scattering inorganic spherical powder such as spherical silica is blended is known.

[0003]

However, when a glitter powder is used to give a glossy or three-dimensional appearance to the skin, it is good in giving a three-dimensional appearance in the finishing characteristics, but the gloss is not good. In many cases, the film was too strong to form an unnatural film or small wrinkles were conspicuous. When spherical silica is used to make small wrinkles inconspicuous, a certain degree of effect is recognized, but the effect is not sufficient, and furthermore, there is a defect that glossiness is lost. Further, in order to solve these drawbacks, it is disclosed in Japanese Patent Application Laid-Open No. H10-87433 that a glitter powder is coated with fine spherical particles on its surface.
However, it is not sufficient to achieve both a natural gloss and an effect of making small wrinkles inconspicuous, and a smooth coating feel is not always satisfactory.

[0004]

Means for Solving the Problems In view of such circumstances, the present inventors have conducted intensive studies and as a result, have found that makeup cosmetics containing hexagonal plate-like aluminum oxide and organic powder and / or glitter powder are obtained. It has been found that when applied to the skin, it imparts a natural luster to the skin, has excellent finishing properties such as an effect of making small wrinkles inconspicuous, and has excellent smooth application feeling, and completed the present invention. .

That is, the present invention provides the following components (a) to
(C); a makeup cosmetic comprising (a) hexagonal plate-like aluminum oxide (b) organic powder and / or (c) glitter powder. Further, the refractive index of the component (b) organic powder is 1.
The makeup cosmetic, which is 3 to 1.7. Still further, the makeup cosmetic is characterized in that the component (c) glittering powder is a boron nitride powder.
