(Evaluation method) I. Usability A panel of 10 experts evaluated the usability of each lipstick in Table 3 (whether it has a smooth feeling of use). Specifically, when it is applied to the lips, it is evaluated whether the inner layer and the outer layer adhere to the lips smoothly and evenly. According to the following absolute evaluation criteria, 7 levels are evaluated and scored. For each lipstick, the average value is calculated from the scores of all members of the evaluation team, and judged by the following criteria.

Absolute evaluation criteria (Rating): (evaluation) 6: Very good 5: Good 4: Slightly better 3: Ordinary 2: slightly worse 1: Poor 0: Very poor Judgment criteria (Judgment): (Average score of score) A: More than 4.5 minutes: Very good B: More than 3 points and less than 4.5 points: Good C: Less than 3 points 　　　　　　　: Bad

II. Filling formability (release property) Visually confirm whether the top surface of the inner layer of lipstick is peeled off when removed from the mold during molding. Those without obvious peeling were evaluated as A, and those with obvious peeling were evaluated as B.

III. High temperature stability (protrusion of the inner layer) Visually confirm whether there is an inner layer emerging after storage at 50°C for 1 week. A person who does not have an emission of 0.5 mm or more is evaluated as A, and a person who has an emission of 0.5 mm or more is evaluated as B.

IV. High temperature stability (shrinkage of the inner layer) Visually confirm whether or not the inner layer shrinks after storage at 50°C for 1 week. A person with no obvious gap between the outer layer and the inner layer was evaluated as A, and a person with a significant gap between the outer layer and the inner layer was evaluated as B.

As can be seen from the results in Table 3, lipsticks 1-14 are all transparent and have high aesthetics. In particular, lipsticks 1, 2, 4, and 5 are lipsticks that have both a colorless and transparent appearance with high aesthetics, a smooth feeling of use, and a cosmetic effect caused by dyes, and are highly stable in high-temperature areas. The lipstick 8 with low hardness in the inner layer is prominent in the inner layer. In addition, lipstick 9 with low hardness of the inner layer may not be able to maintain its shape during application. Lipstick 7 with high hardness of the inner layer and outer layer has slightly poor adhesion during use. The inner and outer layers of lipsticks 1-11 and 13 are colorless and transparent, and the lipstick is colorless and transparent as a whole, with high aesthetics. Furthermore, lipsticks 1 to 11 and 13 are those whose dyes only develop brightly after being applied to the lips, and are those whose makeup effects caused by the dye are excellent.
