Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a cosmetic composition containing starch powder and hydrophobized starch powder, and more specifically, it has an excellent effect of making fine irregularities on the skin such as pores and wrinkles inconspicuous. Moreover, the present invention relates to a cosmetic in which the cosmetic film is natural, has no stickiness, and spreads well.

[0002]

2. Description of the Related Art There are a wide variety of qualities required for finishing cosmetics such as foundations, but recently, the effect of making fine irregularities on the skin such as pores of the skin and wrinkles around the corners of the eyes inconspicuous has been noticed. There is. In the conventional cosmetics, the technique of making these pores and small wrinkles inconspicuous is (1) a technique of blending powder such as spherical silica that diffusely reflects visible light,
(2) A technique of filling fine unevenness on the skin with a cosmetic containing wax to smooth it, and (3) a technique of concealing the entire skin by mixing powder of high refractive index such as titanium oxide. Was there.

[0003]

However, with the technique (1) described above, pores and wrinkles can be made inconspicuous to some extent, but the finished cosmetic film sometimes looks whitish as a whole. Further, in the technique of (2), the spread and spread at the time of applying the cosmetic may be heavy, and a sticky feeling may be felt. Further, with the technique of (3) above, pores and small wrinkles can be hidden, but the finished cosmetic film becomes white and unnatural, and the spread and spread during application of cosmetics may be heavy.

[0004]

Under such circumstances, as a result of intensive studies conducted by the present inventor, it was found that a cosmetic containing starch powder and hydrophobized starch powder in combination solves the above problems. The present invention has been completed.

That is, the present invention provides a cosmetic comprising the following components (a) and (b); (a) starch powder (b) hydrophobized starch powder. Further, the content of the component (a) with respect to all cosmetics is 1 to
20% by mass, and the content of the component (b) with respect to the total cosmetics is 1 to 20% by mass, further comprising spherical powder as the component (c). The present invention provides any of the above cosmetics. Further, the present invention provides any one of the above-mentioned cosmetics characterized in that the cosmetic is an oil-in-water type, and any of the above-mentioned cosmetics characterized in that the cosmetic is for concealing pores and small wrinkles.
