Description

[Technical field]

[0001] The present invention relates to an oil-based solid cosmetic preparation. [Background technology]

[0002] Oil-based solid cosmetics such as eye shadow are cosmetics that are made by filling and molding a cosmetic base material in which an oil component is the main component and a gelling agent, powder components, etc. are mixed into a container such as a plate, and are popular with consumers because they are easy to use and have excellent portability. Since oil-based solid cosmetics are mainly made of oil, it is easy to obtain the transparency of the cosmetic film derived from the oil, and in particular, techniques that combine oil with gelling agents that create transparent gels have been developed. For example, a technique that combines (palmitic acid / octanoic acid) dextrin with solid oils, glittering powders, etc. (see Patent Document 1) and a technique for oil-based makeup cosmetics that uses an amino acid-based gelling agent and a volatile hydrocarbon oil to give the base transparency and a refreshing, non-sticky feel (see Patent Document 2) have been proposed.

[0003] [Patent Document 1] JP 2009-286765 A [Patent Document 2] JP 2013-126957 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the technology of Patent Document 1, although excellent in glittering, has low transparency because it uses solid oils such as wax at room temperature, and the technology of Patent Document 2 has excellent base transparency, non-stickiness, and makeup retention, but tends to cause oil droplets and aqueous components to appear (sweating) in high-temperature environments. In light of this background, there is a demand for oil-based solid cosmetics that are excellent in makeup retention and transparency, are not sticky during use, and have high stability at high temperatures.

[0005] Therefore, an object of the present invention is to provide an oil-based solid cosmetic preparation which has high-temperature stability, a transparent cosmetic film, is non-sticky, and has excellent cosmetic durability. [Means for solving the problem]

[0006] In view of the above situation, the present inventors have conducted intensive research into the phenomenon in which an oil gelled by an amino acid gelling agent separates from the gel structure of the amino acid gelling agent due to molecular vibration of the oil in a high-temperature environment, causing sweating, and the oil agent sweating can be suppressed without impairing transparency by using a component that has oil-binding properties without impairing the transparency of the amino acid gelling agent. As a result of examining various components that have oil-binding properties, the inventors have found that by using a cellulose derivative, it is possible to obtain an oil-based solid cosmetic that is excellent in high-temperature stability by suppressing sweating at high temperatures without impairing transparency. The inventors have also found that by containing an amino acid gelling agent and a cellulose derivative, an oil-based solid cosmetic that has good makeup retention and is less sticky can be obtained, and that by adding a powder, the makeup retention and high-temperature stability of the oil-based solid cosmetic can be further improved, and have completed the present invention.

[0056] (Manufacturing method) A. Heat ingredients (1) to (11) to 130°C and mix and dissolve uniformly. Components (12) to (15) are added to BA and mixed uniformly at 100°C. 2 g of the CB mixture was poured into a metal dish container (2.5 cm length × 2 cm width × 0.3 cm height) and cooled to obtain an eye shadow.

[0057] (Evaluation items) B. Makeup lasts B. Transparency of cosmetic film C. Non-stickiness D. High temperature stability

[0058] (Evaluation method 1) Regarding items A to C, a test was conducted by a panel of 20 experts on each sample. Each panel member used the eyeshadows of Examples 1 to 19 and Comparative Examples 1 to 3, and rated and scored them on a 7-point scale according to the absolute evaluation criteria below. The average score for each sample was calculated from the total scores of all the panel members, and the results were judged according to the following criteria. A. Regarding makeup durability, each sample was applied to the eyelids, and the panel members were asked to live their normal lives for 6 hours, after which the makeup film was evaluated for any breakage due to tears, sweat, or skin movement; B. Regarding the transparency of the makeup film, the makeup film applied to the skin was evaluated for whether the makeup film had a sufficient sense of the brilliance of the glittering powder and whether a sense of transparency was obtained; and C. Regarding the lack of stickiness, the panel members were evaluated for whether the makeup film was sticky when applied to the skin.

[0059] Absolute evaluation criteria (Score):(Evaluation) 6: Very good 5: Good 4: Fairly good 3: Average (neither good nor bad) 2: Somewhat bad 1: Bad 0: Very bad

[0060] (Judgment): (Average score) ◎(A: Good): 5 points or more 〇(B: Fairly good): 3.5 points or more to less than 5 points △(C: Normal): 2 points or more to less than 3.5 points × (D: Bad): Less than 2 points

[0061] (Evaluation method 2) Regarding the evaluation item (ii), each sample was stored at 50°C for two weeks, after which the condition was evaluated by visual inspection for the presence or absence of oil droplets or aqueous components (sweating), and judged according to the following criteria. <Judgment criteria> (Judgment):(Evaluation) ◎(A): No sweating observed at all. ○(B): There is some sweating at high temperatures, but this disappears when returned to room temperature. △(C): Sweating is observed at high temperatures and disappears when returned to room temperature, but sweat marks remain on the surface. ×(D): Significant sweating is observed at high temperatures, and sweating does not disappear even when returned to room temperature.

[0062] As is clear from the results shown in the table, the eye shadows of Examples 1 to 19 were good in all aspects of makeup durability, transparency, non-stickiness, and high-temperature stability. In particular, Examples 1 to 3 and 6 were particularly excellent in all evaluations. On the other hand, Comparative Example 1, which did not contain component (B), and Comparative Example 2, which used silicic anhydride instead, were not satisfactory in terms of transparency, non-stickiness, and high-temperature stability. Comparative Example 3, which used 12-hydroxystearic acid, and Comparative Example 4, which used dextrin (palmitate / octanoate), were particularly unsatisfactory in terms of makeup durability, non-stickiness, and high-temperature stability.
