Description

The present invention relates to lip cosmetics, and more particularly to lip cosmetics having excellent sustainability of smooth spread and spread, glossiness and moisturizing feeling.

In the recent lip cosmetics market, there is a demand for products with excellent functions such as smooth growth, long-lasting makeup, glossiness, and moisturizing feeling, and various studies have been made to produce them. ing.
For example, a technique for producing a glossy and moisturizing feeling by combining a specific hydrocarbon wax and a paste-like oil (see, for example, Patent Document 1), a specific ester-based oil, a dextrin fatty acid ester, and a specific silicone compound. (For example, see Patent Document 2), or by combining a specific heavy oil agent with a solid fat (see, for example, Patent Document 3), a lip cosmetic having excellent glossiness, usability, and stability can be obtained. Technology has been considered.

Japanese Unexamined Patent Publication No. 2013-053141 Japanese Unexamined Patent Publication No. 2008-0192200 Japanese Unexamined Patent Publication No. 2010-260795

However, although the technique of Patent Document 1 can produce a moisturizing feeling, depending on the type and amount of the hydrocarbon wax, the cosmetic film becomes hard, which is satisfactory in terms of softness on the skin and smoothness of spreading and spreading. I couldn't get anything. Further, in the techniques of Patent Documents 2 and 3, although extensibility, sustainability (anti-mobility), glossiness, etc. can be easily obtained, stickiness is anxious, and glossiness and moisturizing feeling cannot be obtained. There was a case.
For this reason, it has been desired to develop a lip cosmetic that spreads smoothly, has a long-lasting glossy feeling, and has an excellent long-lasting moisturizing feeling.

In view of these circumstances, the present inventor, as a result of diligent studies, combined a specific hydrocarbon wax, a specific ester-based oil, and a fumigant anhydrous silicic acid to achieve a smooth spread and spread, particularly stick-like. The present invention has been completed by finding that a lip cosmetic having a soft touch on the skin and a good feeling of use, and having an excellent long-lasting glossy feeling and long-lasting moisturizing feeling can be obtained.

That is, the present invention describes the following components (a) to (c);
(A) Fischer-Tropschwax (b) 12- Stearoyl stearate octyldodecyl (c) Smoke-like silicic acid anhydride is contained , and the content of the component (b) is 0.1 to 40% by mass of the whole. It is a lip cosmetic.

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 cosmetics are stable while maintaining an appropriate viscosity and shape, and are satisfactory in terms of smooth spread and spread, long-lasting glossiness, and long-lasting moisturizing feeling.

The component (b) octyldodecyl stearoyl stearate used in the present invention is an oil agent liquid at 25 ° C. in which octyldodecanol is ester-bonded to an ester of hydroxystearic acid and stearic acid.

As is clear from the results in Table 1, the stick-shaped lipsticks of Examples 1 to 10 of the present invention have smoother spread and spread, softness on the skin, lasting glossiness, and moisturizing as compared with Comparative Examples 1 to 3. The feeling was excellent in sustainability.
On the other hand, in Comparative Example 1 in which polyethylene wax was used instead of Fischer-Tropsch wax of component (a), the cosmetic film became too hard, so that it was satisfactory in terms of smooth spread and softness on the skin. I couldn't get it. Further, in Comparative Example 2 in which the component (b) stearoyl octyldodecyl stearate was not blended, the cosmetic film was sticky, and it became difficult to feel the softness and moisturizing feeling on the skin, which was satisfactory. I couldn't get it. Further, in Comparative Example 3 in which the fuzzy anhydrous silicic acid of the component (c) is not blended, the thickness of the cosmetic film is not obtained, and a satisfactory one is obtained in terms of the sustainability of the glossy feeling and the moisturizing feeling. I couldn't.
