[Effects of the Invention]

[0008] The makeup cosmetic of the present invention exhibits extremely vivid color development due to the oil-soluble dye. DETAILED DESCRIPTION OF THE INVENTION

[0009] Component (A) used in the present invention is a polyglycerol fatty acid ester obtained by esterifying a polyglycerol having an average degree of polymerization of 4 to 15 calculated from the hydroxyl value with a linear or branched fatty acid having 12 to 22 carbon atoms. From the viewpoint that low crystallinity results in high transparency, and that the color development of the dye is not hindered and more vivid color development can be achieved, the fatty acid preferably has 12 to 18 carbon atoms, and from the viewpoint that low crystallinity results in high transparency, and that the color development of the dye is not hindered and more vivid color development can be achieved, the fatty acid is preferably a branched fatty acid, and isostearic acid is more preferred. In component (A), the fatty acid to be esterified may be one or more types, and may be an ester of multiple types of fatty acids that differ in the number of carbon atoms or whether or not they are branched.

[0010] From the viewpoints of preventing a decrease in transparency, not interfering with the color development of the oil-soluble dye, and achieving vivid color development, component (A) preferably satisfies the following relationship: (N × 0.5) ≦ n ≦ (N + 2), where N is the average degree of polymerization of polyglycerol and n is the average number of fatty acids ester-bonded to polyglycerol (the average number of moles of fatty acid added per mole of polyglycerol). Here, the average degree of polymerization of polyglycerol, N, can be calculated, for example, from the hydroxyl value obtained by neutralization titration. Component (A) is preferably a polyglycerol fatty acid ester obtained by esterifying a polyglycerol having an average degree of polymerization N=8 to 12 with a branched fatty acid having 12 to 18 carbon atoms at an average number of added moles n=5 to 12, and more preferably a polyglycerol fatty acid ester obtained by esterifying a polyglycerol having an average degree of polymerization N=8 to 12 with isostearic acid at an average number of added moles n=8 to 12.

The content of component (C) is preferably 20 to 70% by mass, more preferably 30 to 65% by mass, and even more preferably 40 to 60% by mass, based on the total composition.

[0018] In the present invention, the mass ratio of component (A) to component (C) ((A) / (C)) is preferably 0.1 or more, more preferably 0.15 or more, even more preferably 0.2 or more, and is preferably 1 or less, more preferably 0.8 or less, and even more preferably 0.7 or less, from the viewpoint of controlling color development after application by volatilization of component (C) and obtaining vivid color development. Furthermore, the mass ratio of component (A) to component (C) ((A) / (C)) is preferably 0.1 to 1, more preferably 0.15 to 0.8, and even more preferably 0.2 to 0.7.

[0019] The organic oil gelling agent of component (D) is an oil gelling agent whose main component is an organic component, and may be any of those commonly used in cosmetics, such as dextrin fatty acid esters, amino acid-based gelling agents, and waxes with a melting point of 61°C or higher.

[0020] The dextrin fatty acid ester is not limited as long as it is one that is commonly used in cosmetics, and from the viewpoints of usability, storage stability, and oil gelation, an ester of dextrin with a fatty acid having 8 to 24 carbon atoms is preferred, and an ester of dextrin with a fatty acid having 14 to 20 carbon atoms is more preferred. In addition, the average degree of polymerization of the dextrin is preferably 3 to 150. Specific examples include dextrin palmitate, dextrin stearate, dextrin palmitate-stearate, dextrin oleate, dextrin isopalmitate, dextrin isostearate, dextrin myristate, and dextrin palmitate-2-ethylhexanoate. Of these, from the viewpoint of maintaining vividness, dextrin palmitate, dextrin myristate, and dextrin palmitate·2-ethylhexanoate are preferred, and those containing at least dextrin palmitate are more preferred.

[0021] Any amino acid gelling agent may be used without limitation as long as it is used in ordinary cosmetics. Specifically, dibutyl lauroyl glutamide and dibutyl ethyl hexanoyl glutamide are preferred. Commercially available products of these include dibutyl lauroyl glutamide (GP-1) and dibutyl ethylhexanoyl glutamide (EB-21) manufactured by Ajinomoto Co., Inc.

[0022] The amino acid gelling agent can also be used as a premix gel in which it is diluted and dissolved in a solvent in advance, in view of improving workability and excellent oil gelling properties. The solvent is not limited as long as it can gel the oil with the amino acid gelling agent, but from the viewpoint of oil gelling, octyldodecanol, isostearic acid, etc. The content of the amino acid gelling agent in the premix gel is preferably 10 to 45% by mass, more preferably 15 to 40% by mass, and even more preferably 20 to 36% by mass, from the viewpoints of improving workability, preventing oil gelling, and suppressing oil separation from the premix gel itself. As the premix gel, commercially available products such as AJK-OD2046 containing 20% ​​by mass of an amino acid gelling agent and AJK-IS3613 containing 36% by mass (both manufactured by Kokyu Alcohol Co., Ltd.) can be used.

[0023] Waxes with a melting point of 61°C or higher exhibit solid properties at 25°C. 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.

[0024] 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.

[0025] 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.

[0026] Component (D) can be used alone or in combination of two or more, and its content is 4% by mass or more, preferably 4.5% by mass or more, and more preferably 5% by mass or more, based on the total composition, from the viewpoints of providing a coating film with appropriate thickness, adhesion, and vivid color development, and maintaining the vividness, and is 25% by mass or less, preferably 22% by mass or less, and more preferably 19% by mass or less, based on the viewpoints of uniform coating and obtaining vivid color development. The content of component (D) is 4 to 25% by mass, preferably 4.5 to 22% by mass, and more preferably 5 to 19% by mass, based on the total composition.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] The makeup cosmetic of the present invention can be prepared as a makeup cosmetic containing components (A) and (B) in advance in the same cosmetic preparation. Alternatively, it can be prepared by mixing a first cosmetic preparation containing at least component (A) with a second cosmetic preparation containing component (B) before use to finally prepare 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 preparation; they may be formulated separately in two or more agents. By mixing the first cosmetic preparation containing at least component (A) and the second cosmetic preparation containing at least component (B) so that the mass ratio of component (A) to the total amount of the non-volatile oil phase is 0.15 to 0.95, the oil-soluble dye of component (B) can develop color or its color development can be improved. The cosmetic preparation containing component (A) functions as a color-developing agent. In the embodiment in which the components are mixed before use, component (C) and component (D) may be contained in either one or both of the cosmetic preparations, as long as the mass ratio of component (A) to the total amount of the non-volatile oil phase falls within the above-mentioned range and the cosmetic preparation has an appropriate viscosity or hardness that makes it easy to apply. The evaporation of component (C) from the cosmetic preparation after mixing can improve color expression and color development.

[0031] A first cosmetic containing component (A) may be mixed with a second cosmetic containing component (B) before use, or the user may apply the first and second cosmetic compositions to the skin, etc., in layers. In this case, components (A) and (B) may be mixed at the application site (e.g., on the skin or lips) so that the mass ratio of component (A) to the total amount of the non-volatile oil phase is 0.15 to 0.95, and the order of application is not important. Furthermore, components (C) and (D) may be contained in either or both of the cosmetic compositions. As component (C) volatilizes from the coating film after application, users can enjoy changes in color, such as color development and improved color development. Furthermore, each of the above-mentioned cosmetics may be colored by 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 a color, and the color can be changed to a color different from the color of the various pigments before mixing.

[0032] As described above, in the present invention, a user mixes a first cosmetic containing the polyglycerol fatty acid ester of component (A) with a second cosmetic containing the oil-soluble dye of component (B) on the skin or the like, and adjusts the mass ratio of component (A) to the total mass of the non-volatile oil phase containing component (A) at the mixed site to 0.15 to 0.95. This method allows the oil-soluble dye to develop color or improve its color development at the mixed site. In this way, users can enjoy color development, improved color development, and other color changes. For example, two or more cosmetic preparations may be mixed so that the mass ratio of component (A) to the total amount of the non-volatile oil phase is 0.15 to 0.95, or two or more cosmetic preparations with different contents of component (A) may be mixed so that the above mass ratio of component (A) is 0.15 to 0.95. (B) Oil-soluble dye may be contained in any of the cosmetic preparations. Furthermore, the area where the mass ratio of component (A) is 0.15 to 0.95 does not need to be the entire area of ​​the makeup object, but may be a part of it (for example, the area when mixed on the makeup object). [Example]

[0033] Test Example 1 The color development of the oil-soluble dye of component (B) was evaluated when the content of component (A) was changed from 0 to 50 mass % by measuring the color of compositions No. 1 to No. 8 shown in Table 1. The results are also shown in Table 1.

[0034] (Manufacturing method) A total of 300 g was mixed using a 1 L container with a diameter of 130 mm and a disperser blade with a diameter of 30 mm (rotation speed: 2500 rpm throughout the entire process). First, the base materials (excluding the colorant) were heated to 110°C and mixed uniformly for 5 minutes while maintaining the temperature. Next, the colorant was added and mixed uniformly for an additional 2 minutes. After degassing, the mixture was cooled to room temperature and solidified to form a composition.

[0035] (Colorimetry evaluation method) The color measurement samples were prepared by heating and dissolving each composition at 80°C using 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 the mixture to room temperature with the container capped. 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 plate with the bottom facing up. * , 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 represents the vividness of a color, and the larger the value, the more vivid the color.

[0036] [Table 1]

[0037] The results in Table 1 confirm that the color development gradually improves when the content of component (A) is 20% by mass or more, and sufficient color development is obtained when the content is 30% by mass or more.

[0038] Examples 1 to 11, Comparative Examples 1 and 2 (Lip gloss) Lip glosses were prepared with the compositions shown in Table 2. The resulting lip glosses were evaluated for changes in the vividness of the applied product and for the persistence of vividness two hours after application. The results are also shown in Table 2.

[0039] (Manufacturing method) A total 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 rpm throughout the entire process). First, the base materials (excluding component (C) and colorant) were heated to 110°C and mixed uniformly for 5 minutes while maintaining the temperature. Next, the colorant was added and mixed uniformly for another 2 minutes, and finally component (C) was added and mixed uniformly for 1 minute. After degassing, the mixture was cooled to room temperature and solidified. The required amount was cut out from this bulk, heated to 80°C in a microwave oven, melted, poured into a transparent dipping container, and solidified by cooling to obtain a lip gloss. The cosmetic applicator (tip) used had a flat application portion with a flocked surface.

[0040] (Evaluation method) (1) Change in vividness of the applied agent: Ten expert panelists applied each lip gloss to their lips using a tip, comparing the finish immediately after application and five minutes after application, and evaluated the change in vividness of the applied product using the following criteria. The results are shown as the total scores of the 10 expert panelists. 5: The brightness of the applied agent changed considerably. 4: The vividness of the applied agent changed. 3: The vividness of the applied agent changed slightly. 2: The vividness of the applied agent did not change significantly. 1: The vividness of the applied agent did not change

[0041] (2) Duration of vividness of the agent 2 hours after application: Ten expert panelists applied each lip gloss to their lips using a tip, and evaluated the durability of the lip gloss's vividness two hours after application using the following criteria. The results were shown as the total score of the ten expert panelists. Note that samples with an evaluation result of less than 20 for "(1) Change in vividness of the lip gloss after application" were not evaluated because the lasting vividness was poor and evaluation was difficult. 5: The vividness lasts for a long time even 5 minutes after application. 4: The vividness lasts for 5 minutes after application. 3: The vividness persists somewhat 5 minutes after application. 2: The vividness does not last very long 5 minutes after application. 1: The vividness does not last 5 minutes after application.

[0044] Test Example 2 In Example 1, the color of the composition after preparation and the color of the composition after volatilizing the volatile oil were measured in the same manner as in Test Example 1. After evaporation, the agent was spread thinly on a glass plate to a thickness of about 1 mm and left to stand in a dark place at room temperature for about 1 hour to allow the volatile oil to evaporate, after which the agent was recovered and degassed at room temperature. After that, the agent was filled to a height of 9 mm into a transparent resin container with an inner diameter of 42 mm and a height of 12 mm to prepare a sample for color measurement.

[0045] The results are as follows: Value of composition after preparation: L * =48.88, C * =6.62 Value after evaporation of component (C): L * =40.73, C * =41.44 The prepared composition (18% by mass of component (A), 0.1% by mass of component (B)) was unable to fully develop the color of Red No. 218, but after the evaporation of component (C), the concentration of component (A) in the non-volatile oil phase reached 40% by mass, allowing the color of Red No. 218 to be fully developed.

[0046] Example 12 (two-component lip gloss) In the same manner as in Examples 1 to 11, a first part (B1) having the composition shown in Table 3 and a second part (C1) as a color-developing agent containing component (A) were produced. The first agent B1 and the second agent C1 were mixed at a ratio of 1:1 (B:C = 1:1). The lip gloss (Example 12) after mixing at 1:1 was evaluated in the same manner as in Examples 1 to 11 for the change in vividness of the applied agent and the persistence of vividness of the agent 2 hours after application. Furthermore, color measurements were performed on each agent and lip gloss before and after mixing in the same manner as in Test Example 1. The results are also shown in Table 3. The results shown in Table 3 show that after mixing, the lip gloss developed a vivid color over time after application that was completely different from the appearance of each agent before and after mixing.
