Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a base cosmetic containing a bowl-shaped or shell-shaped organic powder, and more particularly, to a base having good adhesion of a foundation and suppressing undesirable gloss on the face, The present invention relates to a base cosmetic composition that produces a matte feeling and has an excellent cosmetic effect.

[0002]

2. Description of the Related Art Conventionally, foundation cosmetics have been used to improve functions such as adhesion of a foundation, feeling of use such as spreading, moisture retention, and protection against ultraviolet rays. The technology includes ester oil and polyhydric alcohol to improve the adhesion and moisturizing properties of the foundation, ethanol to produce a refreshing feeling, titanium oxide and ultraviolet absorption to protect ultraviolet rays. The agent is blended. Further, in order to produce a matte feeling, a spherical powder of silica or the like having a high light scattering effect has been used.

[0003]

However, in the case of conventional base cosmetics, when an ester oil is blended in order to improve the adhesion of the foundation, a luster derived from this oil is generated, and the oil is secreted from the skin over time. Undesirable glossiness such as gloss and shine may increase due to the sebum and the like to be obtained, and it has been difficult to obtain a cosmetic effect having a matte feeling. In addition, when a spherical powder such as silicic anhydride is used to produce a matte feeling, the spherical powder reflects light irregularly, so that the effect of blurring defects on the skin surface (so-called soft focus effect) is exhibited. However, the effect of producing a matte feeling was not sufficient. For this reason, there has been a demand for the development of a base cosmetic composition having a good foundation adhesion and an excellent cosmetic effect for producing a matte feeling.

[0004]

Means for Solving the Problems In view of such circumstances, the present inventors have made intensive studies to solve the above problems, and as a result,
The present inventors have found that a base cosmetic containing an organic powder of a specific shape has a good foundation adhesion and an excellent cosmetic effect for producing a matte feeling, and has completed the present invention. Further, when the base cosmetic contains a polyhydric alcohol, the adhesion of the foundation is further improved, and further, when the base cosmetic contains silicic anhydride, the cosmetic effect for producing a matte feeling is further improved. The present invention has been completed.

That is, the present invention relates to a base cosmetic containing a bowl-shaped or shell-shaped organic powder,
Still further, the base cosmetic containing a polyhydric alcohol,
And, further, the present invention relates to the base cosmetic containing silicic anhydride.

[0006]
