Description

  The present invention relates to makeup cosmetics, and in particular, it is a natural color with transparency, it stretches smoothly and is easy to blur, has a smooth feeling of use, and has an effect of correcting unevenness of the skin surface and time. The present invention relates to makeup cosmetics that are also excellent in stability.

  In makeup cosmetics, oily cosmetics and powders are the cosmetics that combine both the emollient effect and adhesion of oily cosmetics, the smooth spreading and spreading of powdered cosmetics, and the smooth, non-sticky feel. Cosmetics in the middle of body cosmetics are being studied. For example, technologies such as solid cosmetics (see Patent Document 1) containing a large amount of powder including a porous powder and an oil agent have been disclosed. However, in such a technology, a large amount of oily components are contained. Can give skin adhesion, adhesion, and emollient, but may cause stickiness and burden, and the pigments get wet so the color is good, but the natural color with transparency is realized. It was difficult to do.

  On the other hand, examples of makeup cosmetics for finishing transparent skin include irregularity correction cosmetics that have the effect of naturally blurring minute irregularities on the skin surface such as wrinkles and pores. For this, technologies that mix specific elastic powders or scatter light on the skin with a spherical shape (for example, see Patent Documents 2 and 3) are used. However, the feeling of close contact with the skin and the spread of spread were not good, and there were concerns about the stability of the cosmetics.
