Description

  The present invention relates to a stick-shaped lip cosmetic containing rice bran wax, and more particularly to a lip cosmetic capable of obtaining a crumbly light feeling of use, good color development, good adhesion, and uniformity of a cosmetic film.

  Lip cosmetics represented by lipstick and lip gloss have a cosmetic effect of imparting color to the lips and finishing it in a gorgeous impression. In recent years, lip cosmetics have been required to have various effects such as touch and usability in addition to imparting color, and various studies have been made on waxes, oils, and powders that are constituents thereof. I came. For example, a technique for improving shape retention even with a small amount of wax by containing rice bran wax (Patent Document 1), and a long-chain acylamino acid sterol derivative containing a specific hardness range, Technology that satisfies both freshness and sustainability of moisture (Patent Document 2) at the same time, and also contains branched fatty acid and pentaerythritol ester to a specific hardness range, high temperature stability and good releasability and color development And a technique that satisfies both of these requirements (Patent Document 3).

  However, in the technology that improves the shape retention even with a small amount of wax by containing rice bran wax, it is excellent in lightness and gloss, but a sufficient coating amount cannot be obtained, and a cosmetic film that develops color by coating once is obtained. I was not satisfied with the point. In addition, by including a long chain acylamino acid sterol derivative and making it into a specific hardness range, a makeup sustaining effect and a moisturizing feeling can be obtained with respect to a technology that satisfies the durability and moisturizing feeling of a long-lasting makeup and a fresh luster at the same time. However, since the spread becomes heavy, a satisfactory one in terms of usability was not obtained. Furthermore, by containing branched fatty acid and pentaerythritol ester within a specific hardness range, improved color developability can be obtained in technologies that satisfy both high temperature stability, good releasability and good color development. However, no satisfactory product was obtained in that the cosmetic film was sticky and felt uncomfortable during use.

Accordingly, it is an object of the present invention to provide an oily stick upper lip cosmetic capable of producing a crumbly light feeling of use, good color development, good adhesion, and uniformity of a cosmetic film. . In addition, when the cosmetic spreads on the lips, the stick-like cosmetic has a proper adhesion between the skin and the crumble so as to collapse. It is a sense of sticking to the skin while having thickness.

  Under such circumstances, the present inventors have conducted extensive research to solve the above problems, and as a result, combined specific waxes, i.e., rice bran wax, Fischer-Tropsch wax, and candelilla wax, with long-chain acylamino acid sterol derivatives, When rice bran wax and Fischer-Tropsch wax are included in a specific ratio, it has a shape-retaining property as a stick, and a good feeling of use and good adhesion can be obtained. The amount of the cosmetic applied to the lips is increased, and it has been found that an oily lip cosmetic capable of obtaining sufficient color development and a uniform cosmetic film by coating once is obtained, and the present invention has been completed.

That is, the present invention
The following components (A), (B), (C) and (D)
(A) Rice bran wax (B) Fischer-Tropsch wax (C) Candelilla wax (D) A long-chain acylamino acid sterol derivative, wherein component (A) and component (B) are (A) :( B) = 65: 35 The present invention relates to an oily stick-like lip cosmetic having a mass ratio of ˜95: 5 and containing 1 to 10% by mass of component (D).

  The present invention relates to an oily stick-like lip cosmetic capable of producing a crushed and light feeling of use, good color development, good adhesion, and uniformity of a cosmetic film.

Hereinafter, the present invention will be described in detail.
The rice bran wax of the component (A) used in the oily stick-like lip cosmetic of the present invention has the INCI name (International Nomenclature Cosmetic Ingredient labeling name). This is a refined crude wax produced in the ring process. The main components are esters of higher fatty acids and higher alcohols, but they also contain unsaponifiable substances, a small amount of free fatty acids and some hydrocarbons. The melting point of component (A) rice bran wax is not particularly limited, but is preferably 70 to 83 ° C. If it is this range, what produces the good adhesion and the uniformity of the decorative film can be obtained. Examples of commercially available products include FLORA BEADS RBW (melting point: 77 ° C., manufactured by Ikeda Bussan Co., Ltd.), refined rice wax S-100 (melting point: 80 ° C., manufactured by Yokoseki Yushi Kogyo Co., Ltd.), TOWAX-3P3 (melting point: 75 ° C., manufactured by Toa Chemical Industries ) And the like. The component (A) is preferably contained in the cosmetic of the present invention in an amount of 5 to 12% by mass (hereinafter simply referred to as “%”). Within this range, satisfactory results can be obtained in terms of good color development and good adhesion.

  The component (B) Fischer-Tropsch wax used in the oily stick-like lip cosmetic of the present invention is a synthetic hydrocarbon wax produced by the Fischer-Tropsch method. The melting point of component (B) is not particularly limited, but is preferably 70 to 120 ° C. If it is this range, the thing which produces the ease of use and the adhesion | attachment with the lightness which will collapse may be obtained. Examples of commercially available products include SASOLWAX C80 (melting point: 83 ° C.), SASOLWAX H1 (melting point: 97 ° C., manufactured by SASOL), CIREBELLE108 (melting point: 81 ° C.), CIREBELLE109L (melting point: 93 ° C., manufactured by CIREBELLE). The component (B) preferably has a content in the cosmetic of the present invention of 0.4 to 4%. Within this range, satisfactory results can be obtained in terms of good color development and good adhesion.

  The component (C) candelilla wax used in the oily stick-like lip cosmetic of the present invention is an ester fraction obtained by fractionating candelilla wax and has a saponification value of 70 to 100. . Although melting | fusing point is not restrict | limited in particular, The thing of 70 to 85 degreeC is preferable. If it is in this range, a satisfactory one can be obtained in terms of producing good color development. Examples of commercially available products include high melting point candelilla wax FR100 (melting point 80 ° C., manufactured by Nippon Natural Products).
