Description

  The present invention relates to a specific amount of polyethylene wax, a specific amount of fumed silicic acid, a specific amount of heavy liquid isoparaffin and / or polybutene, an ester oil having a glycerin skeleton, an ester oil of malic acid, and pentaerythritol. With regard to oily solid lip cosmetics containing one or more ester oils selected from ester oils and trimethylolpropane ester oils at 25 ° C., in detail, it is excellent in moisture and has a smooth use feeling. The present invention relates to an oily solid lip cosmetic that is excellent in gloss and has excellent stability over time.

Conventionally, oily solid lip cosmetics are composed of solid oil and liquid oil as a main skeleton, and in order to obtain various feelings of use and cosmetic effects, these blending amounts and components have been studied.
For example, liquid oils have been combined with a wide variety of liquid oils such as hydrocarbons, esters, alcohols, and silicones in order to obtain a glossy feeling, a smooth feeling of use, a moisturizing feeling, and a feeling of adhesion. . And in order to harden these, solid oil has also been used combining various things. In particular, in order to make it into a solid state, the solid oil and the liquid oil are not compatible with each other, and those that do not become a solid state or a state in which the liquid oil appears over time on the surface of the cosmetic (perspiration) In order to improve these problems, solid oils and methods for preventing sweating have been studied. (For example, see Patent Documents 1 and 2)

On the other hand, in lip cosmetics, since the lips are very easy to dry, it is required to have a moist feeling and a high moisturizing effect as important qualities. For example, the technique (for example, refer patent document 3) which acquires the rough skin improvement effect by containing vitamin A and / or its fatty acid ester with high skin effect stably is mentioned. In addition, as a technique for imparting a moisturizing effect, a technique has been used in which a paste-like oil agent that forms a thick coating film such as petrolatum is blended and the application part is blocked by the oil film, thereby suppressing moisture evaporation from the application part. .
However, increasing the blending amount of petrolatum increases the moisturizing effect, but on the other hand, the weight and stickiness of the vaseline itself is stronger, and furthermore, the vaseline itself has no gloss, so the gloss feels worse There was a problem. For this reason, it was difficult to have both a moisturizing effect and a gloss effect. Therefore, an oily composition containing a liquid oil was used as an inner core part, and a solid oily composition containing an outer layer part containing a solid oil and a liquid oil. A technique (for example, see Patent Document 4) in which a moisturizing function is imparted to a lip by molding it into a double-structured stick-shaped lip cosmetic material is studied.

  In addition, in order to obtain a gloss, studies have been made using an oil agent having a high refractive index and glittering powder. In addition, for example, a solid oil and / or oily gelling agent, a specific ester oil, and a liquid ester oil and powder having a hydroxyl group in the molecule and a molecular weight of 300 to 1000 at room temperature are added. As a result, a technique for obtaining a uniform coating film with a glossy appearance has been studied for cosmetics for adhesion, moisture, and lips. (For example, see Patent Document 5)

Japanese Patent Laid-Open No. 3-176411 JP 2004-83502 A International Publication No. 2004/032893 Pamphlet JP 2008-105951 A JP 2007-269761 A

  However, with regard to the moisturizing effect, the lips are quite rough unlike the skin, and because the movement and contact with other substances are active due to speaking and eating and drinking, sufficient moisturizing effect is often not obtained. Therefore, it has been desired to develop an oily solid lip cosmetic that suppresses moisture transpiration by blocking the application part with an oil film, that is, has both a moisturizing effect and a glossy feeling due to the moisture occluding property.

  In this situation, the present inventors have conducted extensive research to solve the above problems, and as a result, a specific amount of polyethylene wax, a specific amount of fumed silicic acid, a specific amount of heavy liquid isoparaffin and / or polybutene, , An ester oil having a glycerin skeleton, an ester oil of malic acid, an ester oil of pentaerythritol, an ester oil of trimethylolpropane, or an ester oil that is liquid at 25 ° C. By using polyethylene wax as a solidifying agent, high moisture occlusion is obtained, so it is excellent in moisturizing effect, smooth use feeling is obtained, and uniform and thick coating film is obtained, so it has excellent gloss and stability over time. The present inventors have found that an oily solid lip cosmetic excellent in quality can be obtained, and have completed the present invention.

In addition, sweating was observed when stored at 50 ° C. for 2 weeks. Further, in Comparative Example 2 in which the component (b) was not blended, there was a smooth feeling of use and a uniform coating film, and a glossy feeling was obtained, and a moist feeling over time was obtained. When stored for a week, sweating was observed.
In Comparative Example 3 in which petrolatum was blended instead of component (c), the hardness was so high that a smooth feeling of use was not obtained, and the gloss was not good, and sweating was also generated in stability over time. It was.
In Comparative Example 4 in which the component (d) was not blended, the oily solid lip cosmetic could not be formed due to being too soft.
Further, in Comparative Examples 5 to 9 in which the polyethylene wax of the component (a) was made less than 90% and other waxes were blended, sweating occurred when stored at 50 ° C. for 2 weeks, and further glossiness and smooth use were observed. The lack of feeling and moisture was not satisfactory.

From FIG. 1, the samples of Examples 1 and 3 to 12 showed a value 1.5 times or less that of Example 2, whereas the samples of Comparative Examples 1 to 9 were examples except for Comparative Example 2. A value of 2 or more times 2 was shown.
From this result, it turned out that Examples 1-12 are excellent in the effect which suppresses the water | moisture content from a lip, ie, the moisturizing effect, compared with Comparative Examples 1 and 3-9. In Comparative Example 2, the moisture permeation rate showed a value similar to that in Example 2. However, since component (b) fumed silicic anhydride was not blended, stability over time could not be ensured. In Examples 1 to 12, since the hardness of the obtained samples was low, the elongation spread was good, and as a result, a uniform thick decorative film was formed, and moisture evaporation could be suppressed.
On the other hand, Comparative Example 1 in which ceresin was blended in place of component (a), Comparative Example 3 in which petrolatum was blended in place of component (c), and Comparative Examples 5 to 9 in which component (a) was less than 90% The hardness of the sample became high, and as a result, the decorative film became thin, and the occlusion by the oil film was not obtained.
In Comparative Example 4 in which the component (d) was not blended, the solid shape was not formed, so that the occlusion by the oil film was not obtained.
