[Industrial application fields]
The present invention contains a alkenyl succinate ester of starch and / or a metal salt thereof and a spherical powder, so that it has a smooth and soft feeling of use, has good adhesion and adhesion to the skin, and The present invention relates to a powder cosmetic that is capable of forming a uniform cosmetic film and that has an excellent makeup effect.
[0002]
[Prior art]
The powder cosmetic is a cosmetic used for finishing the makeup, for adjusting the texture of the skin, and for maintaining the makeup effect of the makeup cosmetic such as a foundation. For this reason, powder cosmetics are required to have quality characteristics such as a smooth, uniform stretch and use feeling, and a uniform, fine and transparent cosmetic film. Therefore, conventionally, spherical powders such as nylon and silicic acid anhydride have been blended in order to give a smooth and soft feeling of use. In addition, in order to improve adhesion and adhesion to the skin, it is possible to mix irregular powders and plate powders such as talc and mica, add highly adhesive oils, The method of surface-treating and compounding was carried out.
[0003]
[Problems to be solved by the invention]
However, when a spherical powder such as nylon or silicic acid is blended, a smooth feeling of use can be obtained, but the softness is not satisfactory and the adhesion to the skin / adhesion and the durability of the cosmetic effect are poor. There was a case. In addition, when an irregular powder such as talc or mica or a plate-like powder is blended, the adhesion and adhesion to the skin are improved to some extent, but the smooth and soft feeling of use tends to decrease. Furthermore, even when blended with a highly adhesive oil agent, the adhesion and adhesion to the skin will improve to some extent, but seeking higher adhesion to the skin and increasing the blending amount of the oil agent will repeat the cosmetics. When used, etc., there is a case where the powder is softly agglomerated, resulting in poor adhesion to the props or loss of uniformity of the decorative film.
[0004]
[Means for Solving the Problems]
In view of such circumstances, as a result of intensive studies, the present inventors have found that a powder cosmetic containing an alkenyl succinate ester of starch and / or a metal salt thereof and a spherical powder has a smooth and soft feeling of use. The present inventors have found that the adhesiveness and adhesion to the skin are good, a uniform cosmetic film can be formed, and the cosmetic effect is excellent in sustainability, and the present invention has been completed.
