Description

[Technical field]

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

[0002] It is important for makeup products to maintain the finish they have immediately after application. To achieve long-lasting makeup, film-forming agents are often blended, and the coating properties must be both tough and flexible, as the products are used on moving areas such as the face and lips. For example, in the case of eye makeup cosmetics such as mascara, not only is a high level of toughness required for the coating film to fix the shape, etc. on the surfaces of the eyelids, eyelashes, and eyebrows, but flexibility is also required since they are exposed to blinking and movement more than 10,000 times a day. To date, various technical developments have been made for these products. In particular, in the case of mascara, for example, a cosmetic for eyelashes has been developed that contains a film-forming silicone compound, an organically modified clay mineral compound, a hydrophilic surfactant, and an aprotic polar solvent, and has a water content of 0.5% by mass or less, thereby providing curl retention, water resistance, and being easy to remove with warm water (see Patent Document 1). Also, a mascara has been developed that provides a makeup effect with good staying power over time, by using a mascara product that contains an aqueous medium and a film-forming polyurethane in the form of solid particles dispersed in the aqueous medium, has a viscosity in a specific range at a specific temperature and a specific shear rate, has a reservoir containing a wax-free composition, and has a sealing means with an applicator (see Patent Document 2).

[0003] [Patent Document 1] JP 2017-132732 A [Patent Document 2] JP 2000-178137 A DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0004] However, in the technology of Patent Document 1, when trying to maintain the shape retention, i.e., curl retention and water resistance, the coating film formed is inflexible, and the coating film tends to crack over time. In addition, in the technology of Patent Document 2, the coating film is easily removed with water, especially warm water, and when an oil-soluble film former is added to this technology to improve water resistance, it is difficult to mix with water-dispersible polyurethane, and the film formation tends to be uneven. Therefore, it has been difficult to develop a cosmetic for eyelashes that satisfies high standards of coating film uniformity, adhesion, and drying speed. Therefore, the objective of the present invention is to develop a cosmetic that is excellent in all of the following: cosmetic durability, coating film uniformity, adhesion, and drying speed. [Means for solving the problem]

[0005] As a result of extensive research, the present inventors discovered that by containing a specific silicone polyurethane, an oil-soluble film-forming agent, and a volatile oil, a cosmetic composition can be obtained that exhibits excellent cosmetic durability, uniformity of the coating film, good adhesion, and drying speed of the coating film, and thus completed the present invention.

Evaluation item (a): The drying speed of the coating was measured by applying each sample to the skin or hair, and then measuring the time it took for the sample to disappear when lightly touched with a finger. The drying speed was evaluated according to the following criteria. (Judgment): (Evaluation criteria) 6: Dries in less than a minute 5: Dries in 1 minute or more but less than 2 minutes 4: Dries in 2 to 3 minutes 3: Dries in 3 minutes or more but less than 4 minutes 2: Dry in 4 minutes or more but less than 5 minutes 1: It takes more than 5 minutes to dry (5-level rating scale) (Judgment): (Average score) AA: Over 5.5 points: Best A: More than 5 points, 5.5 points or less: Very good B: 3.5 points or more and 5 points or less: Good C: More than 2 points and 3.5 points or less: slightly poor D: 2 points or less: Defective

[0057] Evaluation item (b): Regarding the uniformity of the coating, each sample was applied to the skin or hair and visually evaluated to see whether the sample was uneven or lumpy. (Absolute evaluation criteria) (Score):(Evaluation) 6: Very good, no unevenness or lumps 5: Good, no unevenness or lumps 4: Good, with no unevenness or lumps 3: Neither 2: Somewhat uneven and lumpy, poor quality 1: Bad, uneven and lumpy 0: Very uneven and lumpy, poor quality (5-level rating scale) (Judgment): (Average score) AA: Over 5.5 points: Best A: More than 5 points, 5.5 points or less: Very good B: 3.5 points or more and 5 points or less: Good C: More than 2 points and 3.5 points or less: slightly poor D: 2 points or less: Defective FIG. 1 shows an image of a part of Example 2 (a mixture of component (A) Production Example 3 + (C) isododecane*3 + (B) trimethylsiloxysilicate*5) dissolved, and a similar image of a part of Comparative Example 1. By improving the dispersibility of components (A) to (C), the uniformity of the coating film tends to increase.

[0058] Evaluation item (c): Regarding makeup durability, each sample was applied to the skin or hair, and the extent to which the coating film had changed six hours later was visually evaluated in comparison to immediately after application. (Absolute evaluation criteria) (Score):(Evaluation) 6: The shape and makeup film are well maintained 5: The shape and cosmetic film are well maintained 4: Fairly good 3: Neither 2: The shape and makeup film are not maintained well. 1: The shape and makeup film are not maintained well. 0: The shape and makeup film are not maintained very well. (5-level rating scale) (Judgment): (Average score) AA: Over 5.5 points: Best A: More than 5 points, 5.5 points or less: Very good B: 3.5 points or more and 5 points or less: Good C: More than 2 points and 3.5 points or less: slightly poor D: 2 points or less: Defective
