In the present invention, the melting point is measured by any of Methods 1, 2, or 3 of the general testing methods in the Quasi-Drug Ingredients Standards. Which method to use should be followed if the Quasi-Drug Ingredients Standards specify the measurement method for each ingredient. If no such method is specified, the measurement method should be selected taking the melting point into consideration. Specifically, Method 1 can be used for high melting points significantly exceeding 80°C, Method 2 can be used for solid fats with lower melting points, and Method 3 can be used for those referred to as paste oils in catalogs, etc.

[0023] Such waxes are not limited as long as they are those commonly used in cosmetics, and examples thereof include mineral waxes such as ozokerite and ceresin; petroleum waxes such as paraffin and microcrystalline wax; synthetic hydrocarbons such as Fischer-Tropsch wax, polyethylene wax, and synthetic hydrocarbon wax; plant waxes such as carnauba wax, candelilla wax, rice wax, and sunflower wax; animal waxes such as beeswax and whale wax; and synthetic waxes such as silicone wax and synthetic beeswax. Of these, paraffin, microcrystalline wax, and synthetic hydrocarbon wax are preferred from the viewpoints of shape retention, feel in use, storage stability, oil gelation, and sustained vividness. From the viewpoints of improving storage stability at high temperatures and improving workability, the wax having a melting point of 61° C. or higher preferably has a melting point of 65° C. or higher and 140° C. or lower, and more preferably 70° C. or higher and 105° C. or lower. Furthermore, from the viewpoint of imparting a smooth, even feel when used, it is preferable that the wax does not contain a wax having a melting point exceeding 105° C.

[0024] As the oil gelling agent of component (D), from the viewpoints of maintaining oil gelation, usability, and vividness, one or more selected from dextrin palmitate, dibutyl lauroyl glutamide, dibutyl ethyl hexanoyl glutamide, and waxes having a melting point of 61°C or higher are preferred.

The content of component (D) is preferably 4 to 25% by mass, more preferably 4.5 to 22% by mass, and even more preferably 5 to 19% by mass, based on the entire composition.

[0026] The makeup cosmetic of the present invention may further contain (E) an organic acid. The organic acid functions as a pH adjuster, can suppress separation of the oil-soluble dye, and can also control the dyeing power upon application. The organic acid may be any that is commonly used in cosmetics, but is not limited thereto. Specifically, one or more selected from citric acid, malic acid, succinic acid, acetic acid, lactic acid, tartaric acid, and fumaric acid are preferred, with citric acid being more preferred. The content of the organic acid in the total composition is preferably 0.001 to 2% by mass, more preferably 0.002 to 1% by mass, and even more preferably 0.005 to 0.5% by mass.

[0027] In addition to the above-mentioned components, the makeup cosmetic of the present invention may contain components used in ordinary cosmetics, such as oily components other than components (A) and (C), colorants other than component (B), powders, surfactants, lower alcohols, polyhydric alcohols, polymeric compounds, ultraviolet absorbers, antioxidants, fragrances, antifouling agents, moisturizers, and water.

[0028] The makeup cosmetic of the present invention can be produced by a conventional method and can be in either a solid or non-solid form. The makeup cosmetic of the present invention is preferably an oil-based cosmetic having an oil as a continuous phase, and can be, for example, lip cosmetics such as lipstick, lip balm, lip gloss, lip oil, lip liner, etc.; or makeup cosmetics such as mascara, eyeliner, eye shadow, cheek color, etc. Among these, lip cosmetics selected from lipstick, lip balm, lip gloss, and lip liner are preferred because of their effective vivid color development.

[0029] The makeup cosmetic of the present invention can be used in a form in which components (A) and (B) are pre-contained in one agent, or in an embodiment in which a cosmetic containing at least component (A) is mixed with another cosmetic prior to use to finally produce a makeup cosmetic containing components (A) and (B). That is, components (A) and (B) do not necessarily have to be contained in the same cosmetic; they may be blended separately in two or more cosmetic agents. A cosmetic containing at least component (A) can then be mixed with a cosmetic containing at least component (B) to allow the oil-soluble dye of component (B) to develop color or improve its color development, and then used. The agent containing component (A) functions as a color-developing agent for the makeup cosmetic. Furthermore, in an embodiment in which color is developed immediately before use, component (C) may be contained in either the cosmetic containing at least component (A) or the other agent, or both.

[0030] In addition, the color former containing component (A) may be mixed with the oil-soluble dye of component (B) by mixing them before use as described above, or by the user applying the color former and the cosmetic containing the oil-soluble dye (B) to the skin or the like in layers. That is, as long as components (A) and (B) are mixed at the application site (e.g., on the skin or lips), the order of application is not critical. For example, the user may apply the color former and then the cosmetic containing the oil-soluble dye (B), or vice versa. However, it is preferable to apply one cosmetic immediately after applying the other. Regardless of the mixing method, similar color development can be achieved. By using in this manner, users can enjoy color changes, such as color development and improved color development. Furthermore, a color-forming agent containing component (A) or a cosmetic containing an oil-soluble dye (B) may be colored by further containing a colorant other than the oil-soluble dye, specifically an organic pigment, an inorganic pigment, a luster pigment, etc. In this case, when the user mixes these, the oil-soluble dye develops color, thereby changing the color to a color different from the color of the various pigments before mixing.

[0031] As described above, in the present invention, a user can use a cosmetic method in which a cosmetic containing component (A) and a cosmetic containing an oil-soluble dye (component (B)) are mixed on the skin or the like, thereby causing the oil-soluble dye to develop color or improving its color development at the site of mixing. In this way, users can enjoy color changes such as color development and improved color development. [Example]

[0032] Examples 1 to 8, Comparative Example 1 (lip gloss) Lip glosses were prepared with the compositions shown in Table 1. The resulting lip glosses were evaluated for color vividness upon application and the durability of vividness two hours after application. The results are also shown in Table 1.

[0033] (Manufacturing method) A total of 300 g was blended using a 1 L container with a diameter of 130 mm and a dispersing blade with a diameter of 30 mm (rotation speed: 2500 r / min throughout the entire process). First, the base ingredients (excluding water and colorant) were heated to 110°C and uniformly mixed for 5 minutes while maintaining the temperature. Next, the colorant was added and uniformly mixed for an additional 2 minutes. After degassing, the mixture was cooled to room temperature and solidified. For Example 8, water was gradually added at room temperature while stirring with the dispersing blade. After the entire amount was added, the mixture was uniformly mixed for 2 minutes and degassed. The required amount was cut out from this bulk, heated to 80°C in a microwave oven, dissolved, poured into a transparent dipping container, and cooled to solidify, yielding a lip gloss. The cosmetic applicator (tip) used had a flattened application portion with a flocked surface.

[0034] (Evaluation method) (1) Vividness of applied color: Ten expert panelists applied each lip gloss to the lips using a tip and then evaluated the vividness of the applied color using the following criteria. The results were shown as the total scores of the 10 expert panelists. 5: The applied color is extremely vivid. 4: The applied color is quite vivid. 3: The applied color is vivid. 2: The applied color is somewhat vivid. 1: The applied color is dull or has no color.

[0035] (2) Duration of vividness 2 hours after application: Ten expert panelists applied each lip gloss to their lips using a tip and rated the durability of vividness two hours after application using the following criteria. The results were shown as the total scores of the 10 expert panelists. Note that samples with a rating of less than 20 for "(1) Vivid applied color" were not evaluated because their lasting vividness was poor and evaluation was difficult. 5: The vividness immediately after application lasts for a long time. 4: The vividness immediately after application lasts. 3: The vividness immediately after application lasts for some time. 2: The vividness immediately after application does not last very long. 1: The vividness immediately after application does not last.

[0036] [Table 1]

[0037] Examples 9 to 10 (two-component lip gloss) In the same manner as in Examples 1 to 8, first agents (B1 and B2) having the compositions shown in Table 2 and second agents (C1 and C2) as color-developing agents containing component (A) were produced. The first agent B1 and the second agent C1, and the first agent B2 and the second agent C2 were mixed in a 1:1 ratio (B:C = 1:1). The lip glosses (Examples 9 and 10) after the 1:1 mixing were evaluated for vividness of the applied color and the durability of vividness two hours after application in the same manner as in Examples 1 to 8. Color measurements were also taken of each agent and lip gloss before and after mixing. The results are shown in Table 2.

[0038] (Colorimetry evaluation method) The color measurement samples were prepared by heating and dissolving each agent and its mixed bulk at 80°C in a microwave oven, filling a transparent resin container with an inner diameter of 42 mm and a height of 12 mm to a height of 9 mm, and then cooling and solidifying it to room temperature. The color was measured using a Minolta Camera Co., Ltd. color difference meter CR-300, with the measurement sample placed on the attached standard white board with the bottom facing up, and the L * , a * , and b * Measure a * , and b * Using saturation C * =√(a *2 +b *2 ) was calculated. This colorimetric value, saturation C * is a value that indicates the vividness of the color, and the larger the value, the more vivid the color. From the results shown in Table 2, it can be seen that the lip gloss after mixing had a vivid color that was completely different from the colors of the individual agents before mixing.

[0039] [Table 2]

[0040] Examples 11-12 (stick lipstick) A stick lipstick having the composition shown in Table 3 was prepared. The resulting stick lipstick had an extremely vivid color when applied, and the color remained vivid even 2 hours after application.

[0041] (Manufacturing method) A total amount of 300 g was blended using a 1 L container with a diameter of 130 mm and a disperser blade with a diameter of 30 mm (rotation speed: 2500 r / min throughout the entire process). First, the base materials (excluding the colorant) were heated to 125°C for Example 11 and 105°C for Example 12, and mixed uniformly for 5 minutes while maintaining the temperature. Next, the colorant was added and mixed uniformly for another 2 minutes. After degassing, the mixture was cooled to room temperature and solidified. The required amount was cut out from this bulk, heated and melted in a microwave oven to 125°C for Example 11 and 105°C for Example 12, poured into a mold, and cooled to solidify, yielding a stick lipstick.

[0042] [Table 3]

[0043] Example 13 (Lip Oil) Lip oils having the compositions shown in Table 4 were prepared in the same manner as in Examples 1 to 8, and the vividness of the applied color and the durability of the vividness two hours after application were evaluated. The results are also shown in Table 4.
