Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an oily solid cosmetic mainly composed of solid oil, liquid oil and powder.

[0002]

2. Description of the Related Art Conventionally, oily solid cosmetics are mainly composed of solid oil, liquid oil and powder, but the drawback of the oil blended for shape retention and filling moldability is that the blending amount is large. As a result, the feeling of oiliness, stickiness, and the like is poor, and in particular, bleeding due to liquid oil content and poor makeup retention due to transfer to clothes and the like appear. Although powder blending reduces its drawbacks, if the powder blending amount increases, not only the above-mentioned shape-retaining property and filling moldability of the oil function cannot be fully exerted, but also the spread at the time of coating deteriorates It becomes impossible to do so, and a so-called “dummy” may occur, resulting in a bad usability. Therefore, there has been a demand for the development of an oily solid cosmetic having excellent shape-retaining properties, filling and molding properties, a feeling of use, and a cosmetic lasting effect.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and its purpose is to have good shape-retaining property during manufacture, good filling and molding property, excellent feeling of use of cosmetics, and long-lasting makeup. It is to provide a good oily solid cosmetic.

[0004]

Means for Solving the Problems The inventors of the present invention have conducted extensive studies to solve the above problems, and as a result, in an oily solid cosmetic mainly composed of solid oil, liquid oil, and powder, were synthesized as powder. It has been found that the above problem can be solved by adding mica and further adding dextrin fatty acid ester, and has completed the present invention.

That is, the present invention is an oily solid cosmetic containing 1 to 15 mass% of solid oil, 15 to 65 mass% of liquid oil, 30 to 70 mass% of powder, and 0.01 to 8 mass% of dextrin fatty acid ester. The synthetic solid mica as the powder is blended in an amount of 1 to 50% by mass in the total amount of the solid oily cosmetic, which is an oily solid cosmetic.

In the present invention, silica can be further compounded, and the compounding amount is 1 in the total amount of the oily solid cosmetic.
It is preferably from 0 to 40 mass%. Blending of silica improves the spreadability of the cosmetic material when applied.
