Description

  The present invention relates to a lip cosmetic, and more particularly, to a lip cosmetic excellent in smooth spreading and spreading, and a long gloss and moisture retention.

The recent market for lip cosmetics demands products with excellent functions such as a smooth feeling of use, makeup, gloss, and moisturizing, and various studies have been made to produce them. ing.
For example, by combining a specific hydrocarbon wax and a pasty oil agent, a technology that produces a feeling of gloss and moistness (see, for example, Patent Document 1), a specific ester oil agent, a dextrin fatty acid ester, and a specific silicone compound (For example, see Patent Document 2), or by combining a specific heavy oil and solid fat (for example, see Patent Document 3), a lip cosmetic with excellent gloss, usability, and stability is obtained. Technology has been studied.

JP2013-053141A JP 2008-019200 A JP 2010-260795 A

However, with the technology of Patent Document 1, although a moist feeling can be produced, depending on the type and blending amount of the hydrocarbon wax, the makeup film becomes hard, which is satisfactory in terms of softness per skin and smoothness of spreading. I couldn't get anything better. In addition, the techniques of Patent Documents 2 and 3 are easy to obtain extensibility, sustainability (anti-mobility), gloss, and the like, but are not worried about stickiness, and cannot maintain the luster and moisture retention. There was a case.
For this reason, it has been desired to develop a lip cosmetic that spreads smoothly, has a lustrous feeling, and has a moisturizing feeling.

  In view of such circumstances, as a result of intensive studies, the inventor of the present invention combined a specific hydrocarbon wax, a specific ester-based oil agent, and fumed silicic anhydride to achieve a smooth expansion, particularly in a stick shape. It was found that a lip cosmetic with a soft feeling on the skin and a good feeling of use, and an excellent persistence of gloss and moisturizing feeling was obtained, and the present invention was completed.

That is, the present invention provides the following components (a) to (c);
It is a lip cosmetic containing (a) Fischer-Tropsch wax (b) octyldodecyl stearoyl stearate (c) fumed silicic acid anhydride.

  The lip cosmetic of the present invention has a smooth spread and is excellent in the persistence of gloss and moisturizing feeling. In addition, even in the case of a stick shape, the skin feel is soft and the usability and functionality are excellent.

Hereinafter, the present invention will be described in detail.
The component (a) Fischer-Tropsch wax used in the present invention is a hydrocarbon wax synthesized from petroleum and imparts an appropriate viscosity to lip cosmetics, and can be used for normal cosmetics. Any molecular weight can be used. As a commercial item, CIREBELLE108, 109L (made by CIREBELLE), FT100 (made by Nippon Seiwa Co., Ltd.) etc. are mentioned, for example.

  The content of the component (a) in the present invention is preferably 0.1 to 20% by mass (hereinafter simply referred to as “%”) in the lip cosmetic, and more preferably 3 to 15%. Within this range, the lip cosmetic is stable with an appropriate viscosity and shape, and is satisfactory in terms of smooth expansion and spread, glossiness and moisture retention.

  Component (b) octyldodecyl stearoyl stearate used in the present invention is a liquid oil at 25 ° C. in which octyldodecanol is ester-bonded to an ester of hydroxystearic acid and stearic acid. Among them, octyldodecyl 12-hydroxystearoyl stearate in which octyldodecanol is bonded to an ester of 12-hydroxystearic acid and stearic acid is preferably used.

As is clear from the results in Table 1, the stick-shaped lipsticks of Examples 1 to 10 of the present invention have a smooth extension and spread, softness per skin, durability of gloss, and moisture retention as compared with Comparative Examples 1 to 3. It was excellent in sustainability.
On the other hand, in Comparative Example 1 in which polyethylene wax is used instead of the Fischer-Tropsch wax of component (a), the cosmetic film becomes too hard, and therefore, satisfactory in terms of smooth spreading and softness per skin. It was not obtained. Further, in Comparative Example 2 in which the component (b) stearoyl octyldodecyl stearate is not blended, the cosmetic film feels sticky, and it is difficult to feel the softness per skin and the persistence of the moisturizing feeling. It was not obtained. Furthermore, in Comparative Example 3 in which the component (c) of fumed silicic acid was not blended, the thickness of the decorative film did not come out, and a satisfactory one was obtained in terms of durability of luster and moisture retention. I couldn't.
