Description

[Technical field]

[0001] The present invention relates to a cosmetic preparation. [Background technology]

[0002] Cosmetics that are excellent in makeup durability and provide a uniform finish have been studied so far. For example, Patent Document 1 describes that a water-in-oil emulsion cosmetic containing a color pigment that has been surface-treated with an amino acid or an N-acylated amino acid, a specific ester oil, and a film-forming agent suppresses streaky unevenness at the start of application, can achieve a uniform finish even if the skin is peeled, and does not crumble over time. Patent Document 2 describes that a water-in-oil emulsion cosmetic containing a non-volatile phenyl-modified silicone, a specific ester oil, a film-forming agent, and a hydrophobically treated color pigment provides a glossy, uniform finish, is free of tightness or powdery feeling on the skin after application, and prevents wrinkles from becoming noticeable even over time.

[0003] [Patent Document 1] JP 2019-147773 A [Patent Document 2] JP 2020-186217 A Summary of the Invention [Problem to be solved by the invention]

[0004] The present inventors have found that conventional cosmetics have a problem in that they feel sticky due to the film-like texture they provide when they dry, and base makeup applied on top of them cannot be applied evenly. [Means for solving the problem]

[0005] The present inventors have discovered that by using a combination of a specific ester oil with other liquid ester oils, a silicone-based film-forming agent, and a non-volatile silicone oil, it is possible to obtain a cosmetic preparation that has a liquid film feel during application, does not have a film-like feel when drying, and does not feel sticky on the skin after drying.

[0006] The present invention comprises the following components (A), (B), (C) and (D): (A) an ester oil selected from pentaerythritol fatty acid esters and dipentaerythritol fatty acid esters which are liquid at 25°C; (B) an ester oil other than component (A) that is liquid at 25°C; (C) a silicone-based film-forming agent, (D) Non-volatile silicone oil that is liquid at 25°C Contains The cosmetic preparation relates to a cosmetic composition in which the mass ratio of component (C) to the total amount of components (A) and (B), (C) / ((A)+(B)), is 1.5 or more. Effect of the Invention

[0007] The cosmetic composition of the present invention has a liquid film feel during application, does not have a film feel when drying, and does not feel sticky to the touch after drying. Furthermore, even if the liquid foundation is applied in layers, there is no unevenness. Furthermore, the feeling of a liquid film during application gives the user a real sense that the cosmetic is adhering to the skin, and this liquid film feeling suppresses the sensation of directly rubbing the skin, thereby reducing the sense of strain on the skin during application. In addition, the absence of a film-like sensation when the cosmetic dries gives the user a sense that the cosmetic has adhered to the skin, and the elimination of this film-like sensation prevents the user from rubbing the skin excessively, thereby reducing the burden on the skin after application.

EXAMPLES

[0047] Examples 1 to 7 and Comparative Examples 1 to 4 A water-in-oil emulsion cosmetic (base cosmetic) with the composition shown in Table 1 was prepared and evaluated for the liquid film feel during application, the lack of a film feel when drying, the lack of stickiness to the skin after drying, and the lack of unevenness of the liquid foundation when applied over it. The results are also shown in Table 1.

[0048] (Production method) The powder components were mixed and ground, added to an oil phase component containing components (A), (B), (C), and (D) that had been mixed separately, and dispersed using a disperser. The aqueous phase component was then added, dispersed using a disperser, and stirred using a homomixer to obtain a water-in-oil emulsion cosmetic (base cosmetic).

[0049] (Evaluation method) (1) Liquid film sensation during application: Each water-in-oil emulsion cosmetic was placed on the fingertip, and the liquid film feel felt while applying to the face was evaluated according to the following criteria. The results were expressed as the total score of the five panelists. 4: During application, you will feel a liquid film. 3: During application, there is a slight feeling of a liquid film. 2: There is little sense of a liquid film during application. 1;There is no liquid sensation during application.

[0050] (2) Lack of coating feel when dry: Each water-in-oil emulsion cosmetic was applied to the fingertips, and the lack of a film-like feel felt when drying on the face was evaluated according to the following criteria. The results were expressed as the total score of the five panelists. 4;There is no feeling of a coating as it dries. 3;When it dries, it doesn't feel like a coating. 2: As it dries, you can feel a slight coating. 1: You can feel the coating as it dries.

[0051] (3) Feels smooth to the touch after drying: Each water-in-oil emulsion cosmetic was applied to the fingertips, and one minute later, the skin surface was stroked with the finger and the feel was evaluated according to the following criteria. The results were expressed as the total score of the five panelists. 4;There is no change in friction and no feeling of resistance. 3;There is almost no change in friction and very little feeling of resistance. 2: There is a slight change in friction and a slight feeling of resistance. 1: There is a change in friction and a feeling of catching.

[0052] (4) Even application of multiple layers of liquid foundation: After applying each water-in-oil emulsion cosmetic, liquid foundation (Sofina Fine Fit Base Foundation Long Keep Liquid SP, manufactured by Kao Corporation) was applied with a finger, and the state of unevenness immediately after application was evaluated sensorily according to the following criteria. The results were shown as the total score of the five panelists. 4; The entire surface of the skin is covered with foundation, so the lines left by your fingers are not visible. 3; Most of the skin surface is covered with foundation, so the lines left by the fingers are hardly visible. 2;Parts of the skin surface are not covered with foundation, and the lines left by the fingers are somewhat noticeable. 1; Most of the skin surface is not covered with foundation, and the lines left by the fingers are noticeable.
