Description

  The present invention relates to a cosmetic.

In recent years, makeup cosmetics spread well and do not cause uneven coating, but also have transparency while covering defects such as color unevenness such as spots, freckles, dullness, and skin irregularities such as pores and wrinkles. There is a demand for a natural finish.
A low-viscosity emulsified cosmetic with a good feeling of use has a good spread, and therefore the decorative film tends to be thin. Therefore, in general, the powder is uniformly adhered to the skin by using a film forming agent. However, when a large amount of the film forming agent is blended, the spread becomes worse and stickiness occurs. In addition, when a film-forming agent having high adhesion is used, there is a problem that a feeling of discomfort such as a film feeling or a feeling of tension is generated on the skin after application.

In addition, in order to improve makeup persistence, a film-forming agent having excellent surface protection is used. For example, a water-in-oil emulsified cosmetic containing trimethylsiloxysilicic acid (Patent Document 1) is known. It has been.
Furthermore, it is known that when a vinyl polymer having a carbosiloxane dendrimer structure in the side chain is used, a strong cosmetic coating film is formed, so that makeup durability such as sebum resistance and friction resistance is improved. (Patent Document 2, Patent Document 3).
