Definitions
- the present invention relates to a finishing cosmetic composition and a cosmetic obtained by filling a dispenser-type container with the finishing cosmetic composition.
- finishing cosmetics that are used by being applied on a makeup-applied face have been developed (for example, Patent Document 1). .
- users are strongly demanding that the foundation does not easily adhere to the mask.
- Organic polymers, silicone-based resins, and the like have been proposed as film-forming agents used in base cosmetics that are directly applied to the skin and general makeup cosmetics (for example, Patent Document 2).
- the present invention is based on such findings, and discloses a cosmetic composition
- a cosmetic composition comprising oil, an oil-soluble coating agent that is a polymer having a specific structure, and water.
- the resin structure comprises a unit represented by SiO 4/2 or a unit represented by R 1 SiO 3/2 (R 1 is a C 1-6 alkyl group or a C 1-6 alkoxy group).
- the linear structure comprises units represented by R 2 SiO 2/2 (R 2 is a C 1-6 alkyl group or a C 1-6 alkoxy group);
- a finishing cosmetic composition comprising an oil-soluble coating agent, which is a polymer in which the resin structure and the linear structure are linked by Si—O—Si bonds, and (C) water.
- [3] The composition according to [1] or [2], wherein the polymer has a hydroxy group.
- the cosmetic according to [10] wherein the composition is sprayed in the form of a mist.
- the cosmetic of [10] or [11], wherein the composition is emulsified by shaking before use.

It comprises an oil-soluble coating agent (hereinafter sometimes referred to as oil-soluble coating agent, polymer, or component (B)), which is a polymer in which a resin structure and a linear structure are linked by Si—O—Si bonds.

本発明に用いられる油溶性被膜剤は、レジン構造とリニア構造の両方の構造を有することが特徴の１つである。一般に、ポリマーがレジン構造のみからなると、その構造に由来する造膜性および粘着性とに優れるが、柔軟性や追従性が不足することがある。ところがポリマーにリニア構造を組み合わせると、ポリマーが柔軟性および追従性を兼ね備えるようになる。このような特徴を有する油溶性被膜剤を含む化粧料を適用すると、柔軟で粘着性のある被膜を形成することができる。これにより、化粧後にこのような被膜が形成されると、マスクや衣服等との擦れや、皮脂や汗等に対して、化粧を保護する層として機能することができるため、化粧崩れを効果的に抑制できると考えられる。
One of the characteristics of the oil-soluble coating agent used in the present invention is that it has both a resin structure and a linear structure. In general, when a polymer has only a resin structure, it is excellent in film-forming properties and adhesiveness derived from its structure, but sometimes lacks flexibility and conformability. However, when a linear structure is combined with a polymer, the polymer has both flexibility and followability. A soft and sticky film can be formed by applying a cosmetic containing an oil-soluble film-forming agent having such characteristics. As a result, when such a film is formed after makeup, it can function as a layer that protects makeup against rubbing against masks, clothes, etc., sebum, sweat, etc., so it is effective for makeup collapse. can be suppressed to
