Description

  The present invention relates to a cosmetic, and more particularly, to a cosmetic that has a high gloss and a covering ability.

Cosmetics such as foundations are required to have a covering power in addition to being required to have a good make-up effect such as giving a glossy finish when applied to the skin. Yes.

Conventionally, scaly powders such as mica, talc, and sericite are blended in cosmetics such as foundations. When this scaly powder is added to the cosmetic, an effect such as imparting an appropriate gloss to the cosmetic film applied on the skin can be expected. It is indispensable. In addition, the cosmetics are often required to have an appropriate covering power in addition to the glossy feeling described above.

  However, since the scaly powder itself does not have a high covering power, titanium cosmetic fine particles (white pigment) and the like are generally further added to the cosmetic. However, because the titanium oxide fine particles have a high covering power, even if a foundation that is toned to the skin color is used, the glossy appearance may appear to disappear depending on the viewing angle of the decorative film. there were.

On the other hand, in a cosmetic containing titanium mica, the amount of titanium dioxide constituting the titanium mica is at least one selected from 25 to 35% by weight and at least 1 selected from 40 to 45% by weight. It is known that cosmetics characterized by containing at least two types of titanium mica have both a covering power and a natural gloss (Patent Document 1). However, there is a problem that a natural glossy feeling cannot be met when a wet feeling of glossiness is required.

  Therefore, there has been a demand for a cosmetic that has a high gloss and a covering finish. On the other hand, a cosmetic containing bismuth oxychloride and a spherical polyurethane powder having a specific particle size distribution satisfies the above requirements. That was not known.

  It is an object of the present invention to provide a cosmetic material that has a high gloss and a finish with a covering power.

In view of such a situation, as a result of earnest research for cosmetics with a high gloss and a covering power, cosmetics containing spherical polyurethane powder having a specific particle size distribution and bismuth oxychloride are problems. Has been found to solve the problem, and the present invention has been achieved. That is, the present invention is as follows.
[1] A cosmetic comprising the following components A and B:
A) Bismuth oxychloride B) Spherical polyurethane powder having a particle size of 1.0 to 40.0 μm [2] Content of bismuth oxychloride is 1.0 to 15.0% by mass [1 ] Cosmetics of description.
[3] The cosmetic according to [1] or [2], wherein the content of the spherical polyurethane powder having a particle size of 1.0 to 40.0 μm is 1.0 to 15.0% by mass.
[4] The cosmetic according to any one of [1] to [3], which is an oily solid.

  ADVANTAGE OF THE INVENTION According to this invention, the cosmetics with a high gloss feeling and the finish with a cover power are obtained.

(1) Bismuth oxychloride which is an essential component of the cosmetic of the present invention.
The cosmetic of the present invention contains bismuth oxychloride as an essential component. Since bismuth oxychloride has a commercial product, it is possible to obtain and use such a commercial product.

In the cosmetic of the present invention, the content of bismuth oxychloride is preferably 1.0 to 15.0% by mass and more preferably 2.0 to 10.0% by mass with respect to the entire cosmetic. . If the content is less than the lower limit, the glossiness may be insufficient. If the content exceeds the upper limit, the glossiness reaches a peak even if the content is increased, which is not preferable.

(2) Spherical polyurethane powder which is an essential component of the cosmetic of the present invention The cosmetic of the present invention contains a spherical polyurethane powder having a particle size of 1.0 to 40.0 μm as an essential component. Such a spherical polyurethane powder can also be obtained, for example, by preparing a conventional spherical polyurethane manufacturing method and then performing an operation such as classification. If the particle size is less than the lower limit, the gloss may be insufficient, and if it exceeds the upper limit, the covering force is insufficient, which is not preferable. Since such a spherical polyurethane has a commercial item, it is also possible to obtain and use such a commercial item. Specific examples of commercially available products include “GRANDPEARL” (Aika Industry Co., Ltd.). In the present invention, the particle size represents a volume average particle size, and is a value measured in ethanol using a laser diffraction / scattering particle size distribution analyzer (device name: Beckman Coulter LS-13 320).

The content of the spherical polyurethane powder in the cosmetic of the present invention is preferably 1.0 to 15.0% by mass, more preferably 5.0 to 10.0% by mass with respect to the total amount of the cosmetic. . By setting it as such a range, sufficient covering power and a glossy finish can be obtained.

(3) The cosmetic of the present invention.
