Description

  The present invention relates to an oily eye cosmetic that is easy to use in props, spreads smoothly, has excellent adhesion to the skin and eyelashes, is strong against bleeding, and hardly adheres to the secondary eye.

  Oily eye cosmetics make the eyes look larger by putting a good color line on the eye contours or by extending eyelashes. Such cosmetics use props such as brushes, brushes, and sponge tips to draw lines on the eyelids, apply them to the eyelashes, and take off the props. There is a need for a makeup-continuation effect that is easy to draw and spreads smoothly, has good adhesion to the skin and eyelashes, and does not bleed due to tears and sebum, and has no secondary adhesion that is difficult to transfer to other parts.

  In order to meet these market demands, efforts have been made to improve functionality, and oil-based makeup cosmetics that combine organic silicone resins and volatile hydrocarbon oils with excellent water resistance and sweat resistance and excellent longevity (Patent Documents) 1), makeup cosmetics containing powders treated with fluorine-modified resins containing silanol groups and methylhydrogenpolysiloxane (see Patent Document 2), silicone resin powders and silicone resins that dissolve in cyclic silicones Cosmetics (see Patent Document 3) have been developed.

JP-A 61-158913 JP-A-9-025216 JP-A-9-143029

  However, the makeup cosmetics obtained by the technique of Patent Document 1 cannot provide a cosmetic effect such as sebum resistance that can satisfy the consumer, and make-up makeup obtained by the technique of Patent Document 2 When applied directly or with a finger, etc., it has a smooth feeling of use and good makeup, but when used with props, there is a tendency for the cosmetics to be poorly removed, such as when the props are not sufficiently removed. As a result, the feeling of use and the longevity of the makeup were also impaired. In addition, in the cosmetics of Patent Document 3, a silicone resin other than fluorine-modified can provide a smooth feeling of use, but the cosmetic durability against blurring is not satisfactory. As in the case, the props were poorly picked up, and the feeling of use and longevity were impaired.

  In such a situation, as a result of intensive studies, the inventor used a combination of a fluorine-modified silicone resin and spherical particles having a so-called konpeito-like shape having silicone fine protrusions on the entire surface of the particle surface. Paying attention to the fact that it is easy to take on props, has excellent usability, and has good makeup, and combining wax and volatile oils, it can be used with props and spreads smoothly and adheres to the skin and eyelashes. The present inventors have found that the makeup sustaining effect is improved by preventing bleeding from moisture such as tears and sebum and preventing secondary adhesion.

That is, the present invention includes the following components (A) to (D):
(A) A fluorine-modified silicone resin having a silanol group in the molecule and having the structure of the following average formula (1): R _1n SiO _{(4-n) / 2} ... Average formula (1)
(However, R ₁ is a hydrocarbon group having 1 to 8 carbon atoms, a phenyl group, a hydroxyl group, or a general formula —R ₂ —Rf, and is arbitrarily selected from functional groups essentially including the general formula —R ₂ —Rf. R ₂ is a divalent alkylene group having 2 to 6 carbon atoms, Rf is a perfluoroalkyl group having 1 to 8 carbon atoms, and n is an average number of 0 <n ≦ 1.8.
(B) Spherical particles having fine silicone protrusions over the entire surface of the particles (C) Wax (D) An oily eye cosmetic containing a volatile oil.

  The oily eye cosmetics of the present invention have excellent usability in props, are easy to draw by spreading smoothly, have excellent adhesion to the skin and eyelashes, and are less likely to bleed into tears, sweat and sebum It is excellent in a long-lasting cosmetic effect that hardly adheres to the secondary surface.
