Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil-based solid cosmetic, and more particularly, to an oil-based solid cosmetic which suppresses the luster of a coating film, provides a natural matte feeling, and is excellent in ease of use during use and excellent filling moldability. It is intended to provide a type cosmetic.

[0002]

2. Description of the Related Art Conventionally, oily solid cosmetics have a solid oil content,
It is composed mainly of semi-solid oil, liquid oil and coloring agent. In order to obtain comfortable usability and feeling of use as cosmetics, the mixing of oils and coloring agents having various shapes and properties has been studied. . In addition, various technical studies have been made on the finish of a coating film in order to obtain a finish that gives a gloss and, on the contrary, a finish that suppresses the gloss and gives a matte feeling. As a technology to give a matte feeling, there are those that mix a large amount of powders or white pigments with high hiding power, or a specific resin powder.However, due to the whiteness of the powder itself, the appearance color of the cosmetics itself Problems such as whitening of the coating film and unnatural white finish of the coating film.In addition, depending on the compounding of a large amount of powder or the type of powder, the spread at the time of coating becomes heavy and the usability is increased. There were problems such as worsening and lowering of the filling moldability.

[0003]

Therefore, the cosmetic color of the oil-based solid cosmetic does not become white in appearance, and when applied, the finished cosmetic film does not become white and unnatural, and a natural matte feeling can be obtained. It has been desired to develop an oil-based solid cosmetic which is excellent in terms of ease of use, fillability and moldability.

[0004]

Under these circumstances, the present inventors have conducted intensive studies to solve the above-mentioned problems, and as a result, by adding a specific amount of a specific component to an oil-based solid cosmetic, the appearance color is improved. It has been found that the coating film does not become white, the finish of the coating film has a natural matte feeling, and that an oil-based solid cosmetic excellent in usability and filling moldability can be obtained, thereby completing the present invention. That is, in the present invention, the component (A) has a low melting point wax of 5 to 25% by weight (hereinafter simply referred to as “%”),
The present invention relates to an oil-based solid cosmetic comprising: component (B) 10 to 50% of a plate-like powder; and component (C) 5 to 25% of a spherical powder.
