Description

[Technical Field]

[0001] This invention relates to a multi-colored solid cosmetic composition. [Background technology]

[0002] Base makeup is makeup applied to make the skin look beautiful. Base makeup products include primers to improve foundation application, foundations to even out skin tone, and concealers to minimize the appearance of blemishes and dark circles. Generally, base makeup products are composed of a single color, such as skin tone.

[0003] In recent years, in order to make the appearance of cosmetics such as foundations more appealing, solid cosmetics have been formed by multi-color filling (Patent Document 1, etc.). These multi-color solid cosmetics are usually used by mixing multiple color compositions when applied to the skin. It has also been reported that using multi-color solid cosmetics in which the mixed multi-color compositions include a combination of advancing and receding colors can give the skin a good sense of depth (Patent Documents 2, 3). Furthermore, a multicolor solid cosmetic is disclosed in which the arrangement of the coloring compositions of each color in the planar direction is maintained the same in the vertical direction, both upward and downward, so that the desired multicolor effect can be obtained from the beginning to the end of use of the multicolor solid cosmetic (Patent Document 4).

[0005] In recent years, there has been a growing preference for makeup that covers imperfections while providing a natural finish and a radiant glow. However, conventional multi-color solid cosmetics have not always provided satisfactory results in terms of skin radiance after application. In particular, oil-gel formulations tended to produce an unnatural shine, making it difficult to achieve the desired radiance. In view of these circumstances, the present invention aims to provide a multi-color solid cosmetic in the form of an oil gel that provides a natural finish with both gloss and transparency. [Means for solving the problem]

[0006] The inventors of the present invention conducted diligent research to solve the above problems and came to the realization that the above problems can be solved if the oil-type multicolor solid cosmetic composition comprises multiple coloring compositions including advancing colors, receding colors, and white, and if the area of ​​each coloring composition on the surface of the cosmetic composition is approximately the same. Thus, the present invention was completed.

[0007] In other words, the present invention is as follows: [1] A multicolor solid cosmetic comprising multiple colored solid compositions arranged in a regular or random manner, The aforementioned plurality of colored solid compositions include white, at least one advancing color, and at least one receding color. A multi-color solid cosmetic in oil gel form, wherein the ratio of the total surface area of ​​each color on the cosmetic surface to the smallest color is 1.5 or less. [2] The multicolor solid cosmetic composition according to [1], wherein the content of titanium dioxide pigment in the white colored solid composition is 1 to 20% by mass relative to the total amount of the white colored solid composition. [3] The advancing color is selected from colors classified as red, reddish-yellow, and yellow in the Munsell color system, and the receding color is selected from colors classified as green, blue-green, and blue in the Munsell color system, as described in [1] or [2]. [4] A multicolor solid cosmetic composition according to any one of [1] to [3], which satisfies the following conditions (a) to (d) when G'' of the plurality of colored solid compositions is measured over time. (a) In all colored solid compositions, G'' is 2.0 to 60 in the entire range of 70°C to 80°C. (b) In the entire range of 70°C to 80°C, the average of the change in G'' (ΔG'' / Δt, Δt=1°C) for multiple colored solid compositions when the temperature rises by 1°C is -0.80 to -15 (c) For all colored solid compositions, the G'' in the entire range of 81°C to 130°C is 0.10 to 8.0 (d) In the entire range of 81℃ to 130℃, the average of the change in G'' (ΔG'' / Δt, Δt=1℃) for multiple colored solid compositions when the temperature increases by 1℃ is -0.00 to -0.50. [5] In a test in which the top surfaces of the first and fifth layers of a multicolor solid cosmetic, obtained by dividing the thickness of the multicolor solid cosmetic into five equal parts, are rubbed with a wet urethane water-repellent material under a load of 2.9 N, the chromaticity difference ΔE between the chromaticity of the cosmetic rubbed with the first layer and the chromaticity of the cosmetic rubbed with the fifth layer is 2.0 or less, as described in any of [1] to [4]. [6] A multicolor solid cosmetic composition according to any one of [1] to [5], wherein the plurality of colored solid compositions consist of fewer than 10 colors. [7] A multicolor solid cosmetic product according to any of [1] to [6], which is a foundation or concealer that exhibits a skin tone when applied to the skin. [Effects of the Invention]

[0008] The present invention provides a multi-color solid cosmetic in the form of an oil-gel that provides a glossy, transparent, and natural finish. In a preferred embodiment, the balance of colors obtained is maintained even with use, thereby maintaining the aforementioned glossy, transparent, and natural finish effects.

Mode for Carrying Out the Invention

[0010] Hereinafter, specific embodiments of the present invention will be described. The multi-color solid cosmetic of the present invention is formed by a plurality of coloring compositions being arranged regularly or at random. In this specification, the arrangement direction of the plurality of coloring compositions is the direction of application to the skin, either through a medium or directly, and is usually a horizontal direction parallel to the opening surface of the container. Specifically, in the case of a cake-type cosmetic, the plurality of coloring compositions are arranged in the planar direction in which the puff slides to transfer the cosmetic onto the puff, and in the case of a stick-type cosmetic, in the application planar direction for application to the skin. Here, "solid" means having no fluidity at room temperature (25°C).

[0011] The multi-color solid cosmetic is not particularly limited as long as it is composed of three or more coloring compositions, and may be three colors, four colors, five or more colors. In some cases, ten or more colors may be used, but if the number of colors of each coloring composition of the cosmetic is too large or too small, the sense of depth is lost and it may be recognized as being flat with a single color. Therefore, it is preferably less than ten colors. The reason for this is that the color of the skin is not constant and varies in lightness and hue depending on the location. In the case of cosmetics as well, it is a collection of different colors, and by appropriately dispersing the colors to represent the skin color, a good sense of depth can be obtained. Also, the multi-color solid cosmetic of the present invention preferably exhibits a skin color when applied to the skin.

[0012] The multi-color solid cosmetic takes a form in which it is divided into sections by color with a plurality of coloring compositions. Here, the number of the plurality of coloring compositions arranged (the number of sections, the number of spots) is not particularly limited as long as it is more than the number of colors of the coloring compositions, and the upper limit is preferably 100 or less. The size (area of ​​each section) of each colored solid composition is not particularly limited, but it is preferable that the ratio of the total area of ​​the largest colored solid composition to the smallest colored solid composition is 1.5 or less, may be 1.4 or less, may be 1.3 or less, or may be 1.25 or less, and that the size of each colored solid composition is approximately the same. By having the area of ​​each color approximately the same in this way, a natural skin tone is presented when applied to the skin, and a desirable gloss and transparency are achieved. If there is a large variation in the area of ​​each color, the skin will have an unnatural finish after application. In particular, if the area of ​​the white colored solid composition is too small, the gloss and transparency will be impaired. Furthermore, the minimum area of ​​the colored solid composition is 0.04 cm² from the perspective of good depth. 2 The above is sufficient, and 0.25 cm 2 The above is sufficient, and also 3cm 2 The following may be used: 1.5 cm 2 The following is acceptable:

[0013] In this specification, "area" of cosmetics and compositions refers to the surface area of ​​the cosmetic or composition that is exposed from the container when it is filled in a container. Typically, the surface on which the puff is slid, or the surface on which the product is applied when applied directly to the skin, corresponds to the "surface."

[0014] The multi-colored solid cosmetic of the present invention has multiple coloring compositions on the surface over which the puff is slid, or on the application surface when applied directly to the skin, and is not a single color. As a result, the colors are unevenly distributed in the cosmetic film, thereby covering imperfections and providing a natural finish and a sense of depth. Color unevenness refers to the large variation in the area ratio (the proportion of pigment occupied by a given area) of the pigments contained in each of the multiple coloring compositions when the cosmetic is applied. Furthermore, as described later, the presence of white in the color distribution of the cosmetic film creates a large gradient of colors on the skin that includes ultra-high brightness areas, resulting in a good glossy and translucent appearance. Normally, attempts to cover skin imperfections often result in an unnatural finish that makes the presence of a makeup film noticeable. However, the multi-color solid cosmetic composition of the present invention achieves both a natural finish with a glossy and translucent appearance and excellent coverage.

[0015] The multicolor solid cosmetic composition of the present invention comprises a plurality of coloring compositions, each containing white, at least one advancing color, and at least one receding color.

[0016] Advancing colors are a general term for colors that appear to stand out from the background and come closer to the subject. They are usually selected from the Munsell color system, specifically from the categories of reddish-purple, red, reddish-yellow, yellow, and yellow-green. Generally, these colors have high brightness and high saturation. Specifically, red, orange, and yellow are representative examples. Receding colors are a general term for colors that appear to recede into the background, and are typically selected from the Munsell color system, specifically from the green, blue-green, blue, blue-violet, and purple categories. Generally, these colors have low brightness and low saturation. Specifically, green, blue-green, blue, blue-violet, and purple are representative examples.

[0017] The aforementioned white colored solid composition exhibits a white color and has an L* value of preferably 90 or higher, more preferably 95 or higher, and even more preferably 98 or higher. It typically contains substantially no colored pigments. "Substantially contained" means that the amount is preferably 0.01% by mass or less, and more preferably 0.001% by mass or less, of the entire composition.

[0018] In the multicolor solid cosmetic composition of the present invention, the surface area occupied by the white colored solid composition is 15 to 40% of the total surface area of ​​the cosmetic composition, more preferably 20 to 35%, and even more preferably 25 to 30%. By setting the range in this way, the amount of white (uneven distribution) when multiple colors are mixed becomes appropriate, and a good gloss and transparency can be imparted to the skin to which the cosmetic is applied.

[0019] The content of titanium dioxide pigment in the white colored solid composition is preferably 1 to 20% by mass, more preferably 5 to 20% by mass, and even more preferably 10 to 15% by mass, based on the total amount of the white colored solid composition. By maintaining this range, a natural finish can be achieved on skin to which the cosmetic product has been applied. If the content of titanium dioxide pigment in the white colored solid composition is too high, the overall brightness may increase too much when the cosmetic product is applied, making it difficult to achieve an appropriate skin tone. Also, if one tries to lower the brightness while increasing the content of titanium dioxide pigment in the white colored solid composition, it becomes necessary to increase the amount of other pigments (red, yellow, etc.), which may result in uneven color when the cosmetic product is applied.

[0020] For a multicolor solid cosmetic composition to exhibit a skin tone on the skin, it is preferable to include black powder. However, when black powder is added to a coloring composition containing red, reddish-yellow, and / or yellow, the appearance tends to become dull. Therefore, it is preferable not to substantially include black powder in a coloring composition containing advancing colors. "Substantially not included" means not including black powder to the extent that the vividness of the coloring composition containing advancing colors becomes dull. For example, the amount of black powder in the total amount of the coloring composition may be 0.8% by mass or less, 0.5% by mass or less, 0.3% by mass or less, 0.1% by mass or less, 0.05% by mass or less, or 0.01% by mass or less.

[0021] On the other hand, even if black powder is added to a coloring composition containing receding colors, the vibrancy of the appearance is not easily lost. For this reason, it is preferable to add black powder to a coloring composition containing receding colors. In this case, the amount of black powder added to a coloring composition containing blue, blue-green, and / or green is usually 0.05% by mass or more, preferably 0.1% by mass or more, and usually 2.0% by mass or less, preferably 1.5% by mass or less, based on the total amount of the coloring composition. Examples of black powders include black iron oxide, carbon black, and titanium black.

[0022] In the multicolor solid cosmetic composition of the present invention, it is preferable that the multiple colored solid compositions satisfy the following conditions (a) to (d) when their G'' (loss modulus of elasticity) is measured over time. (a) For all colored solid compositions, the G'' in the entire range of 70°C to 80°C (also referred to as the "first temperature range" or "first range") is within the numerical range of 2.0 to 60. (b) In the entire range of 70°C to 80°C, the average of the change in G'' (ΔG'' / Δt, Δt=1°C) for multiple colored solid compositions when the temperature rises by 1°C is between -0.80 and -15. It's within range. (c) For all colored solid compositions, the G'' in the entire range of 81°C to 130°C (also referred to as the "second temperature range" or "second range") is within the numerical range of 0.10 to 8.0. (d) In the entire range of 81℃ to 130℃, the average of the change in G'' (ΔG'' / Δt, Δt=1℃) of multiple colored solid compositions when the temperature increases by 1℃ is -0.00 to -0.50. It is within the numerical range.

[0023] Furthermore, the change in G'' (ΔG'') when the temperature rises by 1°C in the above conditions (b) and (d) is... / Δt (Δt=1℃) is the slope of the temperature change graph of G''. Also, multiple colored solids The average of a composition is the average calculated from the change (slope) of multiple colored solid compositions at the same temperature.

[0024] In this invention, G'' is the rheometer AR-G2 (TA Instruments Co., Ltd.) These are values ​​measured using (manufactured by)

[0025] In this way, by satisfying predetermined viscoelastic properties in the first and second temperature ranges of multiple coloring compositions, specifically by having a relatively large change in G'' over temperature in the first range and a relatively small change in G'' over temperature in the second range, it is possible to form a structure in which the planar arrangement of each colored composition constituting the multicolored solid cosmetic is maintained in the same way both vertically upwards and downwards. Furthermore, since the filling of each colored composition in the planar direction proceeds uniformly, it becomes easier to fill the composition so that the area of ​​each color is approximately the same. More specifically, refer to the disclosure in Japanese Patent Publication No. 2020-186211. When G'' of the multiple coloring compositions satisfies the above conditions (a) to (d), the arrangement in the planar direction of the multicolor solid cosmetic formed by the multiple coloring compositions becomes more even. Furthermore, the same arrangement as the appearance is more easily maintained in the vertical direction, both above and below the multicolor solid cosmetic. In other words, since the boundaries of each coloring composition are not disturbed and the intended arrangement is maintained in the vertical direction, the effects of gloss, transparency, and a natural finish can be continuously obtained even as cosmetic use progresses. If the G'' of multiple coloring compositions does not meet the above range, even if the appearance of the arrangement in the planar direction is uniform, the arrangement in the planar direction may differ between the upper and lower vertical directions, or the appearance of the arrangement in the planar direction may be uneven.

[0026] In the multi-color solid cosmetic composition of the present invention, it is preferable that the arrangement of the coloring compositions of each color constituting it in the planar direction is maintained in the same way both vertically upwards and downwards. This makes it possible to continue providing the same desired applied color as initially intended, even as the use of the multi-color solid cosmetic composition increases and the amount of cosmetic composition remaining decreases.

[0027] "Maintaining the same desired application color as at the beginning" can be confirmed by the small difference in the color tone of the cosmetic transferred to the applicator or the skin between the initial use of the cosmetic and when the use progresses. More specifically, a multicolor solid cosmetic is divided into layers with its thickness equally divided into five parts, and the top surfaces of each layer of the top layer (the first layer) and the bottom layer (the fifth layer) are rubbed against the surface of the multicolor solid cosmetic with a load of 2.9 N using a makeup puff made of a wet urethane water-repellent treatment material with a size of 52×44×8.5 mm. Here, the "thickness" is the vertical length of the cosmetic, and the "layer" refers to the cosmetic divided in the horizontal direction. In the test of the multicolor solid cosmetic of the present invention, the chromaticity difference ΔE between the chromaticity of the cosmetic rubbed off in the first layer and the chromaticity of the cosmetic rubbed off in the fifth layer is preferably 2.0 or less, more preferably 1.5 or less, and even more preferably 1.0 or less. The chromaticity difference ΔE is an index representing numerically the color difference when any two colors are expressed in Lab values, and can be calculated by the following formula. ΔE ab =〔(ΔL) 2 +(Δa) 2 +(Δb) 2 〕 1 / 2 The number of times of color measurement by rubbing off each layer is preferably 10 times or more, more preferably 15 times or more, and it is preferable to use the average of the chromaticity of each layer when calculating the chromaticity difference.

[0028] A makeup puff made of a wet urethane water-repellent treatment material with a size of 52×44×8.5 mm is a popular makeup puff used in the market, and the load of 2.9 N when rubbing off the cosmetic is assumed to be the load applied when a normal woman rubs off the cosmetic with a puff. Also, the chromaticity difference of the cosmetic can be measured, for example, by applying the rubbed-off cosmetic on an acrylic white board using the puff used for rubbing off the cosmetic, and measuring the makeup film on the acrylic white board with a spectrocolorimeter (SD5000 manufactured by Nippon Denshoku, D65 light source). For further demonstration that the same desired application color as initially intended is maintained in a multicolor solid cosmetic when G'' of multiple coloring compositions satisfies the above conditions (a) to (d), please refer to the disclosure in Japanese Patent Application Publication No. 2020-186211.

[0029] The multicolor solid cosmetic composition of the present invention can be manufactured by filling the plurality of coloring compositions into a container such as a metal dish. The temperature conditions during filling are preferably 70 to 130°C, more preferably 80 to 100°C, and even more preferably 85 to 95°C. Typically, the mixture is cooled to room temperature after filling to obtain a solid cosmetic composition. When manufacturing the multicolor solid cosmetic composition of the present invention, it is preferable that the multiple coloring compositions be filled into containers simultaneously. Here, "simultaneously" means that the start and end of filling into containers occur at the same time. More preferably, the filling speeds of the multiple coloring compositions are approximately the same.

[0030] The shape of the multiple colored compositions in the direction of arrangement is not particularly limited and may be round, rectangular, polygonal, irregular, marbled, etc. From the viewpoint of design, it is preferable to have at least a part or the whole of the arrangement arranged in a marbled pattern. Furthermore, these may be arranged regularly or randomly. From the viewpoint of maintaining a consistent color of the cosmetic product rubbed off with a puff, multiple colored compositions of substantially the same shape may be arranged regularly, for example, a swirling marble pattern of substantially the same width (Figure 1) or a checkerboard pattern.

[0031] The shape of the multi-colored solid cosmetic of the present invention is usually round or roughly rectangular when it is a cake type, considering compact storage, but it is not limited to these. Here, roughly rectangular means a shape that is close to a rectangle, but includes those with rounded corners. A round shape has the advantage of allowing the solid cosmetic to be used uniformly to the very end. The thickness of the cake is also not particularly limited, and is usually 0.1 cm or more, 0.2 cm or more, and usually 2.5 cm or less, preferably about 1.0 cm or less. On the other hand, in the case of stick-type devices, they are usually stick-shaped, and their length and diameter are set as appropriate.

[0032] The multicolor solid cosmetic composition of the present invention is in the form of an oil gel. Furthermore, examples of the multicolor solid cosmetic composition of the present invention include, but are not limited to, foundation, concealer, blush, and eye color, although foundation and concealer are more preferred. The concealer may be applied before or after the foundation, but applying it afterward is preferable because it enhances the effect of providing gloss, transparency, and depth, and suppresses creasing of the cosmetic film (Japanese Patent Publication No. 2020-007242).

[0033] The raw materials used in the multicolor solid cosmetic composition of the present invention will be described below. 1) Powder The powders that can be used in the multicolor solid cosmetic composition of the present invention refer to a general term for organic or inorganic solids that do not dissolve in cosmetic raw materials such as water, oils and fats, surfactants, alcohols, and silicones.

The shape of the powder may be spherical, irregular, porous, hollow, fibrous, plate-like, or lumpy. Furthermore, its surface may be subjected to commonly known surface treatments such as silicone coating, metal soap coating, or acyl amino acid salt coating.

[0034] Each coloring composition may contain only one type of powder, or a combination of two or more types. In the multicolor solid cosmetic composition of the present invention, the amount of powder is usually 30% by mass or more, preferably 40% by mass or more, in the multicolor solid cosmetic composition and / or the coloring composition. Furthermore, it is usually 70% by mass or less, preferably 60% by mass or less.

[0035] 2) Oily components The multicolored solid cosmetic composition of the present invention typically contains an oily component. Specific examples of oily components include, for example, animal and vegetable oils such as macadamia nut oil, avocado oil, corn oil, olive oil, rapeseed oil, sesame oil, castor oil, safflower oil, cottonseed oil, jojoba oil, coconut oil, palm oil, and liquid lanolin; hydrocarbon oils such as liquid paraffin, squalane, and pristane; liquid fatty acids such as oleic acid and isostearic acid; liquid higher alcohols such as isostearyl alcohol and octyldodecanol; cetyl isooctanoate, isopropyl myristate, hexyldecyl isostearate, diisopropyl adipate, di-2-ethylhexyl sebatate, cetyl lactate, diisostearyl malate, ethylene glycol di-2-ethylhexanoate, neopentyl glycol dicaprate, glycerin di-2-heptylundecanoate, tri-2- Examples include synthetic ester oils such as glycerin ethylhexanoate, cetyl ethylhexanoate, trimethylolpropane tri-2-ethylhexanoate, trimethylolpropane triisostearate, pentane erythritol tetra-2-ethylhexanoate, glyceryl triisostearate, and glyceryl triisooctanate; linear polysiloxanes such as dimethylpolysiloxane, methylphenylpolysiloxane, and diphenylpolysiloxane; cyclic polysiloxanes such as octamethylcyclotetrasiloxane, decamethylcyclopentasiloxane, and dodecamethylcyclohexanesiloxane; and silicone oils such as modified polysiloxanes such as amino-modified polysiloxane, polyether-modified polysiloxane, alkyl-modified polysiloxane, and fluorine-modified polysiloxane. However, those belonging to the specific surfactant groups described later shall not be treated as oily components.

[0036] The oily component may be included alone, or in combination of two or more types. The oily component content is typically 30% by mass or more in the multicolor solid cosmetic composition, preferably 40% by mass or more. Furthermore, it is typically 70% by mass or less, preferably 60% by mass or less.

[0037] Furthermore, it is preferable that the oily component contains solid fat and / or semi-solid fat, with the content being preferably 3% by mass or more of the total composition, and more preferably 5% by mass or more. Also, it is preferable that the content be 10% by mass or less of the total composition, and more preferably 8% by mass or less. Here, solid fats include semi-solid fats. Solid fats are defined as those that are not fluid at 25°C, while semi-solid fats are those that hardly deform under stress at 1 atmosphere and 20°C, but are susceptible to slight stress (10-100 g / cm²). 2 This refers to materials that deform when subjected to a certain degree of stress. Furthermore, materials with a melting point of 50°C or higher are more preferable. Examples of solid fats and / or semi-solid fats include plant-derived carnauba wax, Japanese wax, candelilla wax, rice bran wax, shea butter, African mango butter, etc., and animal-derived beeswax, shellac wax, privet wax, etc. Examples of derived waxes include refined waxes such as paraffin wax and microcrystalline wax, while examples of mineral-derived waxes include refined waxes such as ozokerite, ceresin, and montane wax.

[0038] Furthermore, in order to stably form an oil gel formulation, it is also preferable to include an oily gelling agent in addition to or instead of the aforementioned solid fat or semi-solid fat. Here, an oily gelling agent refers to a gelling agent that is compatible with oily components such as oils, and is not particularly limited, but examples include 12-hydroxystearic acid, dextrin palmitate, (palmitic acid / octanoic acid) dextrin, dibutyl lauroyl glutamide, and dimethicone crosspolymer. The content of the oily gelling agent is preferably 0.5% by mass or more of the total composition, more preferably 2% by mass or more, and even more preferably 5% by mass or more. Furthermore, it is preferably 10% by mass or less of the total composition, more preferably 8% by mass or less, and even more preferably 6% by mass or less. In a preferred embodiment, the cosmetic composition contains 3 to 15% by mass of any one selected from the group consisting of solid fats, semi-solid fats, and oily gelling agents, based on the total amount of the cosmetic composition.

[0045] <Preparation of multi-colored solid cosmetic> A multicolored solid cosmetic composition consisting of four colored compositions was prepared according to the formulations shown in Table 1. First, A was heated to 105-110°C and stirred and mixed, then adjusted to 85-90°C, and B was added and stirred and mixed to prepare the colored compositions for each color. The G'' of each colored composition before filling is measured using a rheometer AR-G2 (TA Instrument). Using a device manufactured by ments, measurements were taken under the following conditions, and it was confirmed that the conditions (a) to (d) described above were met. Program: Temperature sweep Vibration stress: 30 Pa Measurement temperature: 20℃~150℃ Gap: 1000 μm Four colored compositions were simultaneously poured into a 5cm diameter circular gold dish under 85°C conditions to obtain a multi-colored solid foundation divided into four colors, as shown in the photograph in Figure 1. The ratio of the largest color to the smallest color on the surface of the cosmetic was calculated from the number of pixels of each color measured from a digital photograph of the cosmetic taken from directly above. As a comparative example 2, a multi-colored solid cosmetic consisting of three colored compositions without white was similarly prepared as shown in the photograph in Figure 2.

[0046] <Sensory evaluation> Each cosmetic product was applied to the skin using a puff that had been wiped clean once, and then evaluated by experienced evaluators on a four-point scale (◎: Excellent, ○: Good, △: Average, ×: Poor) based on whether it "presented a natural skin tone," "had a glossy finish," "had transparency," and "had coverage." The results are shown in Table 2.

[0047] [Table 1]

[0048] [Table 2]

[0049] Comparing Example 3 with Comparative Example 2, it can be seen that the presence of white in multiple colored solids results in superior gloss and transparency, leading to a more natural finish. From the results of Comparative Example 1 and Examples 1-4, it can be seen that by setting the ratio of the largest color to the smallest color in each colored composition to 1.5 or less, a glossy finish with natural transparency can be achieved.

[0050] <Measurement of ultra-high brightness regions> Each cosmetic product from Example 3 and Comparative Example 2 was applied to the subject's face, and a frontal photograph of the subject's face was taken using a VISIA-Evolution skin measurement device (Canfield Scientific Inc.) in standard light mode. The subject wore a gray cape and closed their eyes while being photographed with an image correction color chart (CASMATCH). A 500 x 500 pixel area below the eye and beside the nostril was cropped from the obtained photograph, and the brightness of each pixel in this area was measured in 250 levels. The proportion of pixels in the ultra-high brightness area (230-250 levels) contained within this area was calculated as the ultra-high brightness area prevalence rate. The results are shown in Figure 3. Compared to Comparative Example 2, a multicolored solid cosmetic that did not contain white, Example 3, a multicolored solid cosmetic containing white among multiple colored solids, showed a higher proportion of ultra-high brightness regions and was able to produce a transparent, glossy appearance.
