Description

Technical Field

[0001] The present invention relates to a multicolor solid cosmetic.

Background Art

[0002] Base makeup is makeup applied to make the skin look beautiful. Examples of base makeup cosmetics include makeup bases for improving the application of foundation, foundations for adjusting skin color, concealers for making spots and dark circles less noticeable, etc. In addition, base makeup cosmetics are generally composed of a single-color composition such as skin color.

[0003] In recent years, in order to make the appearance of cosmetics themselves, such as foundation, attractive, solid cosmetics have been formed by multi-color filling (see Patent Document 1, etc.). These multi-color solid cosmetics are usually used by mixing a plurality of color compositions when applied to the skin. It has also been reported that when using a multi-color solid cosmetic in which the plurality of color compositions to be mixed includes a combination of advancing colors and receding colors, a good sense of depth can be imparted to the skin (Patent Documents 2 and 3).

Summary of the Invention

Problems to be Solved by the Invention

[0005] In recent years, makeup with a transparent and natural finish while covering drawbacks has been preferred. However, conventional multi-color solid cosmetics have not always been satisfactory in terms of the transparency of the skin after application. In view of these circumstances, the present invention aims to provide a multi-color solid cosmetic that achieves both transparency and a natural finish, as well as good coverage. [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 multiple coloring compositions constituting the multicolor solid cosmetic include a predetermined amount of white in addition to advancing and receding colors, and thus completed the present invention.

[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 multicolored solid cosmetic in which the surface area occupied by the white colored solid composition is 15-30% of the total surface area of ​​the cosmetic. [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] Divided into eight or more sections by the plurality of colored solid compositions, [1] to [3] A multi-colored solid cosmetic as described in any of the following. [5] A multicolor solid cosmetic composition according to any one of [1] to [4], wherein the plurality of colored solid compositions consist of fewer than 10 colors. [6] A multi-color solid cosmetic according to any of [1] to [5], which is a foundation that exhibits a skin-colored appearance when applied to the skin. [Effects of the Invention]

[0008] The present invention provides a multi-color solid cosmetic that achieves both transparency and a natural finish, as well as good coverage. Furthermore, by mixing multiple colors of the multi-color solid cosmetic of the present invention and applying them, a sense of depth can also be added. [Brief explanation of the drawing]

[0009] [Figure 1] This is a schematic diagram showing the approximate shape of the cosmetics prepared in the examples and comparative examples (5 colors). [Figure 2] This is a schematic diagram showing the approximate shape of the cosmetic products prepared using the comparative examples (4 colors). [Modes for carrying out the invention]

[0010] Specific embodiments of the present invention will be described below. The multicolor solid cosmetic of the present invention is formed by arranging multiple coloring compositions in a regular or random manner. In this specification, the direction of arrangement of the multiple coloring compositions is the direction in which the cosmetic is applied to the skin, either through a medium or directly, and is usually a horizontal direction parallel to the opening of the container. Specifically, in the case of a cake-type cosmetic, the multiple coloring compositions are arranged in the plane direction in which the puff is slid to transfer the cosmetic onto the puff, and in the case of a stick-type cosmetic, the multiple coloring compositions are arranged in the application plane direction in which the cosmetic is applied to the skin. In this context, "solid" refers to a substance that does not have fluidity at room temperature (25°C).

[0011] A multi-colored solid cosmetic composition is not particularly limited as long as it consists of two or more colored compositions, and may have two, three, four, or five or more colors. In some cases, ten or more colors may be used, but if the number of colors in each colored composition of the cosmetic is too many or too few, the sense of depth will be lost and it may be perceived as a single color and flat, so it is preferable to have fewer than ten colors. The reason for this is that skin color is not uniform, with variations in brightness and hue depending on the location. Similarly, cosmetics are a collection of different colors, and by appropriately dispersing these colors to represent skin tone, a good sense of depth can be achieved. Further, when the multicolor solid cosmetic of the present invention is applied to the skin, it preferably exhibits a skin color.

[0012] The multicolor solid cosmetic is in a state divided into a plurality of colored compositions for each color. The number of the plurality of colored compositions (number of compartments, number of spots) arranged here is not particularly limited as long as it is greater than or equal to the number of colors of the colored composition, preferably 8 or more, more preferably 15 or more, still more preferably 25 or more, even more preferably 35 or more, particularly preferably 40 or more, and also preferably 100 or less, more preferably 95 or less, still more preferably 90 or less. The size (area of the compartment) of each colored solid composition is not particularly limited, but the area ratio of the largest colored solid composition to the smallest colored solid composition may be 5 or less, 4 or less, 3 or less, 2 or less, and it is preferable that the sizes of the respective colored solid compositions are substantially the same. Also, the area of the smallest colored solid composition may be 0.04 cm 2 or more, may be 0.25 cm 2 or more, and may also be 3 cm 2 or less, and may be 1.5 cm 2 or less.

[0013] In this specification, the "area" of a cosmetic or a composition refers to the area of the surface (outer surface) of the cosmetic or composition filled in a container or the like that is exposed from the container. Usually, the surface where the puff slides, or when directly applying to the skin, the application surface corresponds to the "surface".

[0014] The multicolor solid cosmetic of the present invention has a plurality of the number of colored compositions on the plane where the puff slides, or on the application plane when directly applying to the skin, and does not become a single color. As a result, the colors are unevenly distributed in the cosmetic film, thereby covering the defects while presenting a natural finish and a sense of depth. The uneven distribution of colors means that when the cosmetic is applied, the variation in the content area ratio (the ratio of the pigment occupying in a certain area) of the pigments contained in the plurality of colored compositions is large. In addition, since white exists in the unevenly distributed color on the makeup film as described below, a good transparency is imparted. Transparency refers to a state that appears clear and see-through without dullness. Normally, when trying to cover skin flaws, it tends to result in an unnatural finish that makes the presence of the makeup film noticeable. However, the multi-color solid cosmetic of the present invention can achieve both a natural finish with transparency and a covering power.

[0015] The multi-color solid cosmetic of the present invention contains white, at least one advancing color, and at least one receding color in a plurality of colored compositions.

[0016] Advancing colors are a general term for colors that appear to stand out and come closer from the background color. Usually, they are selected from colors classified as red-violet, red, red-yellow, yellow, and yellow-green in the Munsell color system. Generally, they are colors with high lightness and high chroma. Specifically, red, orange, yellow, etc. can be cited as representative colors. Receding colors are a general term for colors that appear to be drawn back and seen deeper from the background color. Usually, they are selected from colors classified as green, blue-green, blue, blue-violet, and purple in the Munsell color system. Generally, they are colors with low lightness and low chroma. Specifically, green, blue-green, blue, blue-violet, purple, etc. can be cited as representative colors.

[0017] The white-colored solid composition exhibits white and preferably has an L* value of 90 or more, more preferably 95 or more, and even more preferably 98 or more. Usually, it substantially does not contain a colored pigment. Substantially not containing means preferably 0.01% by mass or less, more preferably 0.001% by mass or less of the whole composition.

[0018] In the multi-color solid cosmetic of the present invention, the surface area occupied by the white-colored solid composition is 15 - 30% with respect to the entire surface of the cosmetic, more preferably 15 - 25%, and even more preferably 15 - 20%. By setting it within such a range, the content (uneven distribution amount) of white becomes appropriate when mixing multiple colors, and a good transparency can be imparted to the skin coated with the cosmetic.

[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] 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. Powder-type cosmetics are usually prepared using a wet process. For oil-gel and emulsion-type cosmetics, for example, a coloring composition heated to 70-130°C is used for filling, and then the mixture is cooled to room temperature to obtain a solid cosmetic.

[0023] The shape of the multiple colored compositions in the direction of arrangement is not particularly limited and may be round, rectangular, polygonal, irregular, marbled, or any other shape. Furthermore, they may be arranged regularly or randomly. From the viewpoint of maintaining a consistent color for the cosmetic product rubbed off with a puff, multiple colored compositions of substantially the same shape may be arranged regularly, for example, in a checkerboard pattern.

[0024] 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.

[0025] The multicolor solid cosmetic composition of the present invention is not particularly limited as long as it is solid, and may be in powder form, oil gel form, or emulsion form. Furthermore, examples of the multi-colored solid cosmetic composition of the present invention include, but are not limited to, foundation, face powder, concealer, blush, eye color, etc.

[0026] 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.

Furthermore, its surface may be subjected to commonly known surface treatments such as silicone coating, metal soap coating, or acyl amino acid salt coating.

[0027] 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 powder, in the case of a powder type, is usually 65% ​​by mass or more in the multicolor solid cosmetic composition and / or coloring composition, preferably 70% by mass or more, more preferably 75% by mass or more, and even more preferably 80% by mass or more. Also, it is usually 95% by mass or less, preferably 90% by mass or less, and more preferably 85% by mass or less.

Also, it is usually 70% by mass or less, preferably 60% by mass or less.

[0028] 2) Oily components The multicolored solid cosmetic composition of the present invention may contain oily components. 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.

[0029] The oily component may be included alone, or in combination of two or more types. When an oily component is incorporated into the multicolor solid cosmetic composition of the present invention, in the case of a powder type, the amount of the oily component is usually 5% by mass or more, and preferably 10% by mass or more, of the multicolor solid cosmetic composition. Furthermore, the amount is usually 25% by mass or less, and preferably 20% by mass or less. In the case of oil gel type, the content of oily components is usually 30% by mass or more, preferably 40% by mass or more, in the multicolor solid cosmetic composition. Also, it is usually 70% by mass or less, preferably 60% by mass or less.

[0030] Furthermore, in the case of an oil gel type, it is preferable to include solid fat and / or semi-solid fat as an oily component, and the content thereof is preferably 3% by mass or more of the total composition, more preferably 5% by mass or more. Also, it is preferable to include 10% by mass or less of the total composition, and more preferably 8% by mass or less.

[0031] 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., animal-derived beeswax, shellac wax, privet wax, etc., petroleum-derived refined waxes such as paraffin wax and microcrystalline wax, and mineral-derived refined waxes such as ozokerite, ceresin, and montan wax.

[0032] If the composition of the present invention is in the form of an oil gel, it is also preferable to include an oily gelling agent in addition to or instead of the solid fat or semi-solid fat mentioned above. 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, 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 the case of an oil gel type, a preferred embodiment contains 3 to 15% by mass of any of the group consisting of solid fats, semi-solid fats, and oily gelling agents, based on the total amount of the cosmetic.

[0038] The present invention will be described in more detail below with reference to examples, but the technical scope of the present invention is not limited to the examples provided.

[0039] <Preparation of multi-colored solid cosmetic> Multicolored solid cosmetic compositions consisting of five or four colored compositions were prepared according to the formulations shown in Tables 1-3. For colored solids other than white, the content of colored pigments was adjusted between formulations to achieve a similar skin tone after application. Specifically, for each coloring composition, the powder component was mixed in a Henschel mixer, and then the oil component was added and mixed further to obtain a mixture. The resulting mixture was then pulverized in a pulperizer to obtain each coloring composition. Next, a roughly rectangular metal tray with partitions was filled with different cosmetic compositions, ensuring that the compartments separated by the partitions did not mix. The partitions were then removed, and the tray was pressure-molded using a 20 kg hand press to obtain a multi-color solid foundation as shown in Figure 1 or Figure 2. Similarly, a single-color solid foundation of skin tone, Comparative Example 4, was obtained using a metal tray without partitions.

[0040] For each foundation in the examples and comparative examples, a skilled evaluator assessed the coverage, natural finish, and transparency of the foundation when applied to the skin using a puff that had been wiped horizontally. The results were evaluated on a four-point scale (◎: Excellent, ○: Good, △: Average, ×: Poor). The results are shown in Tables 1-3.

[0041] [Table 1]

[0042] [Table 2]

[0043] [Table 3]

[0044] Comparing Example 1 and Comparative Example 3, the presence of white in multiple colored solids results in transparency. It is recognized that this will result in superior intuition. Comparing Example 1 with Comparative Example 4, it can be seen that the mixture of multiple colors is superior to the single-color skin tone in terms of both transparency and natural finish. The results from Examples 1-7 show that when the titanium dioxide pigment content in the white colored solid is 1-20% by mass, the finished product looks more natural. Comparing Example 1 with Comparative Examples 1 and 2, it can be seen that when the area of ​​the white colored solid is set to 15-30%, the transparency and finish are better.
