Description

  The present invention relates to an eyeliner cosmetic, and more particularly to an eyeliner cosmetic that extends smoothly, has excellent adhesion to the skin and ease of overlaying, and has an excellent makeup sustaining effect.

  Eyeliner cosmetics make your eyes look bigger by putting lines with good color on the eye contours. In addition, due to the usage method of drawing on the outline of the eye, there is a demand for easy-to-draw lines that can be smoothly drawn, makeup that does not bleed due to tears and sebum, and polo removal due to continuous movement of wrinkles. Recently, makeup that emphasizes the eyes has become popular, and in order to further emphasize the eyes, eyeliner cosmetics are layered on top of each other to draw thin lines and thick lines, and to draw dark and clear eye lines. Not only smooth usability, but also ease of overlaying has become important.

  In order to meet these market demands, efforts have been made to improve the function, and an oil-based makeup cosmetic that blends an organic silicone resin and a volatile hydrocarbon oil, has good water resistance and sweat resistance, and has a long lasting makeup (Patent Document 1). ) And water-based eyeliner technology (see Patent Document 2) that has good color development and stability over time by combining microbial-derived polysaccharides with volatile alcohols, alkyl acrylate copolymer emulsions, glitter pigments, etc. It has been. In addition, in order to obtain a smooth feeling of use, which is a quality required for eyeliner cosmetics, an acrylic-silicone graft copolymer, spherical fine particle powder, and low-boiling silicone oil are blended to provide excellent cosmetic sustainability. Liquid makeup cosmetics (see Patent Document 3) that have good ductility and excellent usability, and liquid eye that contains spherical and plate-like powders, has a smooth and easy-to-draw usability, and has excellent makeup sustainability There was technology such as liner cosmetics (see Patent Document 4).

Japanese Patent Publication No. 6-15453 Japanese Patent No. 4299294 JP 2002-047140 A Japanese Patent Laid-Open No. 11-302126

  However, the cosmetics obtained by the technique of Patent Document 1 cannot provide a cosmetic effect such as sebum resistance enough to satisfy consumers, and the eyeliner cosmetics obtained by the technique of Patent Document 2 No makeup, satisfactory skin adhesion, is obtained. Moreover, in the cosmetics blended with the spherical powders of Patent Document 3 and Patent Document 4, although a smooth feeling of use can be obtained, the adhesion when superimposed is not sufficient, and the examination mentioned there is not made. .

  In this situation, the present inventors have conducted intensive studies, and as a result, spherical particles having a so-called confetti-like shape having fine silicone protrusions on the entire surface of the particle surface have a smooth feeling of use while being applied to the skin. Focusing on the excellent adhesion, not only is it easy to put together by blending it into a good-looking eyeliner cosmetic containing a film-forming component, a volatile component, and a colorant, The present inventors have found that the effect of maintaining makeup that prevents bleeding from moisture such as tears and sebum is further improved, and the present invention has been completed.

That is, the present invention includes the following components (A) to (D):
(A) Spherical particles having microscopic protrusions of silicone over the entire surface of the particle (B) Film-forming component (C) Volatile component (D) The present invention relates to an eyeliner cosmetic comprising a coloring agent. is there.

  The eyeliner cosmetic composition of the present invention is easy to draw on the eyelids by spreading smoothly and is excellent in adhesion, so that it is easy to overlay and can draw an eyeline of the desired shape and density, It has excellent makeup that does not easily bleed into tears and sweat, and does not easily peel off even when the eyelids move.

Hereinafter, the present invention will be described in detail.
The spherical particles (A) used in the eyeliner cosmetic of the present invention having silicone fine protrusions over the entire surface of the particle surface are characterized by the shape thereof, and the silicone fine protrusions are entirely formed on the surface of the base spherical particle. And has a shape like so-called konpeito. The average particle diameter is not particularly limited, but is preferably 1 to 30 μm, and more preferably 3.5 to 10 μm. Further, it is desirable that (average height of protrusions) / (average particle diameter of spherical particles serving as a base) is 0.01 to 0.3. These include those described in Japanese Patent Application Laid-Open Nos. 2008-137953 and 2009-280570, and as commercially available products, both the spherical particles serving as the base and the protrusions are polymethylsilsesquioxane. TOSPEARL 150KA (made by Momentive Performance Materials), Silcrusta MK03 (made by Nikko Rika Co., Ltd.), whose spherical particles as the base material are methyl methacrylate crosspolymer, and the projections on the surface are polymethylsilsesquioxane ) Etc.

(Evaluation item)
A. Smooth expansion and spread b. Adhesion to skin c. Ease of overlaying d. Coloring by overlapping. With regard to the items of makeup holding i to ho, a use test was conducted by 20 specialist panels for each sample. Each sample was applied to the skin three times in succession, and the ease of layering was determined by whether or not the samples overlap to create a uniform film, and whether a decorative film color was obtained at that time. Evaluated as color development. After applying, after having applied the normal life to the panel, evaluate whether the makeup film is not blotted by tears or sweat after 6 hours, or whether the makeup film is partially peeled off did. About each item, each panel person evaluated in seven grades by the following absolute evaluation criteria, gave a score, the average value was calculated from the total score of all the panels, and judged by the following four-step judgment criteria.
