Description

  The present invention relates to a cosmetic.

In recent years, make-up cosmetics are natural in spite of the fact that they spread well and do not cause uneven coating, but also cover defects such as stains, freckles, dullness, and other skin irregularities such as pores and wrinkles. It is required to be finished.
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 powder having a high refractive index and a film forming agent. For example, Patent Document 1 discloses a cosmetic that uses trimethylsiloxysilicic acid and has excellent sustainability such as an ultraviolet ray prevention effect. 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 in that the skin after application has a discomfort such as a feeling of film or a feeling of tension.
In addition, all of these methods have excellent adhesion to the skin immediately after finishing, but the skin unevenness part is low, such as low sebum resistance, conspicuous pores, wrinkles and wrinkles over time. There was a problem that would stand out.

  In addition, when a vinyl polymer having a carbosiloxane dendrimer structure in the side chain is used, a strong cosmetic coating film is formed, and it is known that cosmetic durability such as sebum resistance and friction resistance is improved. (Patent Document 2). However, since such a polymer forms a very hard film, it is inferior in feeling of use and smoothness of finish although it is excellent in physical action such as friction. Further, once collapsed, agglomeration of pigments such as iron oxide occurs and is difficult to repair. Furthermore, since a decorative coating film made of a vinyl polymer having a carbosiloxane dendrimer structure in the side chain has a property that a substance is difficult to adhere thereon, it is difficult to uniformly attach a powder such as a funny powder. That is, it has been found that there is a new problem that it is difficult to remake.

(Manufacturing method)
After the components (1) to (5) are uniformly mixed, the components (6) to (8) are dispersed with a disper. To this, the mixture of components (9) to (11) is gradually added with stirring and emulsified to obtain the desired water-in-oil emulsion foundation.
((A) / (B) = 4)
((A) / (C) = 1.33)
(Particles of 2 μm or less; 9% by mass)

  Each of the water-in-oil emulsified cosmetics obtained in Examples 9 and 10 has a good feeling of use and forms a uniform cosmetic film on the skin, has a small film feeling after being applied to the skin, and adheres to the skin. It is excellent in the effect of making fine lines and pores inconspicuous. In addition, the makeup persistence is good, and pores and kinks are less noticeable over time. In addition, it is easy to remake.
