[Modes for carrying out the invention]

[0018] According to one embodiment, the present invention relates to a multi-color powder-molded cosmetic. The multi-color powder-molded cosmetic of this embodiment is a powder cosmetic containing the following components (i) and (ii) that is filled and molded into a single container. (i) A first powder cosmetic composition containing 6% by mass or more of a first opacifying powder having a refractive index of 1.7 or higher. (ii) A second powder cosmetic composition containing a second opacity powder having a refractive index of 1.7 or higher, wherein the content ratio of the second opacity powder in the second powder cosmetic composition is 1 / 2 or less of the content ratio of the first opacity powder in the first powder cosmetic composition.

[0019] Here, a multi-color powder-molded cosmetic refers to a cosmetic in which two or more powder cosmetic compositions with different color tones are molded together as a single unit. "Different color tones" means that the powder cosmetic compositions satisfy the relationship of opacity powder content as defined in (i) and (ii) above. In this specification, a powder cosmetic composition refers to a cosmetic composition in which the powder component accounts for 80% by mass or more, preferably 85% by mass or more, when the total mass of the composition is taken as 100%. The compositions (i) and (ii) that constitute each cosmetic will be described below.

[0020] (i) First powder cosmetic composition The first powder cosmetic composition is a composition containing 6% by mass or more of a first opacifying powder having a refractive index of 1.7 or higher. The first powder cosmetic composition may typically be a powder foundation, and may be a powder foundation with higher opacity compared to the second powder cosmetic composition described later.

[0021] The first powder cosmetic composition contains a first opacity powder as an essential component. In this embodiment, the opacity powder refers to a powder with a refractive index of 1.7 or higher. In this specification, the opacity powder contained in the first powder cosmetic composition is referred to as the first opacity powder. The refractive index of the first opacity powder is preferably 2.0 or higher, and more preferably 2.5 or higher. Among the opacity powders, boron nitride is an example of a powder with a refractive index of about 1.7, zinc oxide is an example of a powder with a refractive index of about 2.0, and titanium oxide is an example of a powder with a refractive index of about 2.5, but is not limited to these. Any other compound with a refractive index of 1.7 or higher can be used as the opacity powder, and the type of compound is not limited. The first opacity powder may be a mixture of two or more different powders with refractive indices of 1.7 or higher.

[0022] The shape of the first opacifying powder may be any shape, including tubular, plate-shaped, needle-shaped, spherical, petal-shaped, irregularly shaped, or a combination thereof. The average particle size of the first opacifying powder is not particularly limited and may be an average particle size commonly used in powder cosmetics such as powder foundations where opacity is required.

[0023] In this invention, pearlescent agents are not included in the opacity powder. Pearlescent agents are generally substances in which mica (sericite) is coated with titanium dioxide. Pearlescent agents having a titanium dioxide layer on the surface may have a refractive index of 1.7 or higher, but the inclusion of pearlescent agents may result in excessive pearlescent, glossy, and metallic effects, and the same opacity function as powders with a refractive index of 1.7 or higher that do not contain pearlescent agents cannot be expected.

[0024] The first opacifying powder is included in an amount of 6% by mass or more, when the total mass of the first powder cosmetic composition is considered to be 100%. This is to give the first powder cosmetic composition higher opacity compared to the second powder cosmetic composition. The content of the first opacifying powder can be set appropriately depending on the purpose and application, for example, 8% by mass or more, or 10% by mass or more, as long as it is 6% by mass or more. On the other hand, the upper limit of the content of the first opacifying powder can be set to, for example, about 25% by mass. By increasing the content of the first opacifying powder, it is possible to maximize the opacity, and prevention of blemishes and dullness can be expected to be more effective. On the other hand, if the content of the first opacifying powder is too high, it may become difficult to apply and the usability may be impaired, so it is preferable to keep it below the predetermined upper limit.

[0025] The first powder cosmetic composition may contain any powder component other than the first opacity powder, and any such powder component may be an extender powder or a colored powder that does not meet the definition of the first opacity powder.

[0026] Examples of extender powders include talc, mica, sericite, kaolin, aluminum silicate, and calcium carbonate. The extender powder may also be a powder whose surface has been modified with silicone or the like. These extender powders have a refractive index of approximately 1.5 to 1.6 and can be used as a base component of the powder cosmetic composition for the purpose of adjusting transparency and gloss and improving the feel of use. The extender powder can be present in an amount of approximately 55 to 70% by mass when the total mass of the first powder cosmetic composition is considered to be 100%.

[0027] As the coloring powder, pigments commonly used in foundations can be used, and may include, but are not limited to, coloring pigments such as titanium dioxide, iron oxide, titanium mica, and organic tar-based dyes. Titanium mica can be used as a pearlescent agent. The coloring powder can be included in the usual amount found in cosmetics.

[0028] The first powder cosmetic composition may further contain any optional ingredients depending on the purpose and use. Optional ingredients may include binders, surfactants, antioxidants, emulsifiers, dispersants, preservatives, humectants, polyhydric alcohols, lower alcohols, sugars, UV absorbers, whitening agents, skin activators, blood circulation promoters, anti-seborrheic agents, anti-inflammatory agents, astringents, cooling agents, fragrances, and other such agents.

[0029] The first powder cosmetic composition may contain a dispersant. Examples of dispersants include polyglyceryl-10 decaisostearate and sorbitan sesquiisostearate, but are not limited to any specific compound.

[0030] The first powder cosmetic composition may contain an ultraviolet absorber. Examples of ultraviolet absorbers include ethylhexyl methoxycinnamate, but the composition is not limited to any specific compound.

[0031] The first powder cosmetic composition may contain spherical powder for improved usability. Examples of spherical powder include spherical silica, spherical urethane powder, spherical silicone powder, spherical calcium carbonate, spherical polymethyl methacrylate, and spherical nylon powder. More specifically, (lauryl methacrylate / glycol dimethacrylate) crosspolymer is an example, but the composition is not limited to any particular compound.

[0032] The first powder cosmetic composition may also use an oily component or water as a binder. The oily component can be a liquid oil that is liquid from room temperature to the cosmetic manufacturing temperature (25-80°C). Examples include hydrocarbons such as liquid paraffin and squalane; esters such as isopropyl myristate, octyldodecyl myristate, di-2-ethylhexyl sebacate, neopentyl glycol di-2-ethylhexanoate, neopentyl glycol dicaprate, glyceryl tri-2-ethylhexanoate, diglyceryl triisostearate, pentaerythritol tetra-2-ethylhexanoate, dipentaerythritol 2-ethylhexanoic acid, trimethylolpropane tri-2-ethylhexanoate, and diisostearyl malate; oils and fats such as olive oil and castor oil; higher fatty acids such as isostearic acid and oleic acid; higher alcohols such as isostearyl alcohol and oleyl alcohol; and silicone oils such as dimethylpolysiloxane, methylphenylpolysiloxane, and decamethylcyclopentasiloxane. The oily component in the present invention can be any one or more of the above selected and used. A mixture of semi-solid oil or solid oil with the above oily component may also be used. As semi-solid oils, for example, petrolatum, cholesteryl hydroxystearate, hydrogenated castor oil stearate, and dipentaerythritol fatty acid (12-hydroxystearic acid, stearic acid, rosinic acid, etc.) esters may be used. As solid oils, oils and fats such as hydrogenated oil and Japanese wax; hydrocarbons such as ceresin, microcrystalline wax, paraffin wax, and polyethylene wax; waxes such as beeswax, candelilla wax, and carnauba wax; higher fatty acids such as stearic acid and behenic acid; and higher alcohols such as cetanol may be used. The powder cosmetic composition of the present invention may further contain emulsifying compositions such as water-in-oil emulsion compositions and oil-in-water emulsion compositions as other components. The content of oily components is preferably not more than 20% by mass when the total mass of the first powder cosmetic composition is taken as 100%, and can be about 5 to 15% by mass.

[0033] (ii) Second powder cosmetic composition The second powder cosmetic composition contains a second opacity powder with a refractive index of 1.7 or higher, and the content ratio of the second opacity powder in the second powder cosmetic composition is 1 / 2 or less of the content ratio of the first opacity powder in the first powder cosmetic composition.

[0034] The second powder cosmetic composition may also typically be a powder foundation, and may be a powder foundation with lower opacity compared to the first powder cosmetic composition.

[0035] The second powder cosmetic composition also contains an opacity powder, similar to the first powder cosmetic composition. In this specification, the opacity powder contained in the second powder cosmetic composition is referred to as the second opacity powder. The definition and options for the second opacity powder are the same as those for the first opacity powder. Therefore, the composition of the second opacity powder may be the same as or different from that of the first opacity powder. If the compositions are different, it is preferable that the refractive index of the second opacity powder is smaller than that of the first opacity powder.

[0036] The shape and average particle size of the second opacity powder can also be selected from the options exemplified for the first opacity powder. Therefore, the shape and average particle size of the second opacity powder may be the same as or different from those of the first opacity powder.

[0037] The content of the second opacifying powder in the second powder cosmetic composition shall be 1 / 2 or less of the content of the first opacifying powder in the first powder cosmetic composition. This ensures a difference in opacity between the first and second powder cosmetic compositions, thereby clearly defining the difference in functionality. Note that the content of the second opacifying powder in the second powder cosmetic composition may be zero. Therefore, in this case, the second powder cosmetic composition may not contain any opacifying powder.

[0038] The second powder cosmetic composition may contain any component other than the second opacifying powder. The optional component can be selected from the same options as the optional component in the first powder cosmetic composition. In one embodiment, the substance used as an optional component in the second powder cosmetic composition may be the same as the substance used as an optional component in the first powder cosmetic composition. In this case, the content of the optional component, excluding the extender powder, may also be the same. The amount of extender powder added can be increased or decreased as appropriate to adjust (balance) the content of each component.

[0039] In the multi-color powder-molded cosmetic composition according to this embodiment, a first powder cosmetic composition and a second powder cosmetic composition are filled and molded into a single container to constitute the powder cosmetic composition.

[0040] In multicolor powder-molded cosmetics, the filling methods for the first powder cosmetic composition and the second powder cosmetic composition may include (A) filling them separately with a boundary line, and (B) filling them in a gradient manner. Each of these will be explained below.

[0041] (A) Fill separately with a boundary line According to one embodiment, a first powder cosmetic composition and a second powder cosmetic composition are filled adjacent to each other, and a boundary line is provided to distinguish the filled areas of the first powder cosmetic composition and the second powder cosmetic composition. In this embodiment, the arrangement of the first powder cosmetic composition and the second powder cosmetic composition will be further described with reference to the drawings. Figure 1 is a conceptual plan view of the multicolor powder molded cosmetic of this embodiment, and Figure 2 is a conceptual cross-sectional view along line AA in Figure 1.

[0042] The multicolor powder-molded cosmetic composition 1 shown in Figures 1 and 2 is filled separately in a container 14 with a first powder cosmetic composition 11 and a second powder cosmetic composition 12. In Figures 1 and 2, the boundary line 13 indicates the boundary between the first powder cosmetic composition 11 and the second powder cosmetic composition 12. In this specification, "having a boundary line" between the first powder cosmetic composition 11 and the second powder cosmetic composition 12 means that the first powder cosmetic composition 11 and the second powder cosmetic composition 12 are adjacent but exist separately without substantially mixing, and that when the cross-section shown in Figure 2 is analyzed, a line indicating a change in composition can be shown. Therefore, however, there is no substance or partition at the boundary, and the first powder cosmetic composition 11 and the second powder cosmetic composition 12 are in contact.

[0043] The illustrated container 14 has a square shape with rounded corners when viewed from above, and has a depth capable of containing the first powder cosmetic composition 11 and the second powder cosmetic composition 12. The container 14 may be made of metal, plastic, or any material whose properties do not change under manufacturing conditions.

[0044] The volume ratio of the filling amount of the first powder cosmetic composition to the filling amount of the second powder cosmetic composition is not particularly limited and can be set appropriately according to the purpose and application. For example, it can be around 2:8 to 8:2, or 4:6 to 6:4, or they may be the same volume, but it is not limited to a specific ratio.

[0045] Next, the multi-color powder-molded cosmetic 1 will be described from the perspective of its method of use. In this specification, in Figure 1, the direction indicated by arrow X is referred to as the first direction or direction X, and the direction indicated by arrow Y is referred to as the second direction or direction Y. The second direction is defined as the "direction of use." The direction of use is the direction in which the application means is moved to adhere the cosmetic to the application means when using the multi-color powder-molded cosmetic 1. By moving the application means in a predetermined "direction of use" and rubbing off the multi-color powder-molded cosmetic 1, it becomes possible to adjust the thickness of the coating, which is the objective of this invention.

[0046] The direction of use can be indicated on the container, or on the cosmetic itself by embossing or printing, as in the embodiment of the multicolor powder-molded cosmetic 1. Alternatively, it can be indicated on the instruction manual attached to the container or on the protective film. In Figure 1, a roughly rectangular container is used as an example to show the direction of use, but even if the container is polygonal, circular, or elliptical in shape, the first and second directions can be determined by providing an indication of the direction of use, making the above method of use possible.

[0047] When using the multi-color powder-molded cosmetic 1, the user can apply the cosmetic to the application means by bringing the application means into contact with the multi-color powder-molded cosmetic 1 and moving it in a second direction. The application means may be a foundation sponge, brush, or the user's fingers, and is not particularly limited. When the application means is moved in the Y direction at the left end of the multi-color powder-molded cosmetic 1 in Figure 1, i.e., the base end of arrow X, a large amount of the first powder cosmetic composition 11 can be applied to the application means. This allows the user to achieve a thick application that emphasizes coverage. On the other hand, when the application means is moved in the Y direction at the right end of the multi-color powder-molded cosmetic 1 in Figure 1, i.e., the tip end of arrow X, a large amount of the second powder cosmetic composition 12 can be applied to the application means. This allows the user to achieve a thin application that emphasizes a more natural skin look. When the application means is moved in the Y direction in the middle of the container, the first powder cosmetic composition 11 and the second powder cosmetic composition 12 can be applied to the application means to an equal degree. This allows the user to obtain an intermediate level of coverage. In this embodiment, when the application means is moved in the Y direction to rub off the cosmetic, it is preferable to move it from near the lower edge to near the upper edge of the container in Figure 1, and it is preferable to reciprocate multiple times to pick up the cosmetic with the application means.

[0048] Referring to Figure 1, the filling ratio of the first powder cosmetic composition 11 and the second powder cosmetic composition 12 along the Y direction changes continuously along the X direction. The "filling ratio of the first powder cosmetic composition and the second powder cosmetic composition along the Y direction" can be expressed as the ratio of the length of the line that crosses the first powder cosmetic composition to the length that crosses the second powder cosmetic composition when a straight line parallel to the Y axis is extrapolated in a two-dimensional plane viewed from above of the filling portion of a container filled with multicolor powder molded cosmetic, with the lower edge of the container parallel to the X direction as the X axis and the left edge of the container parallel to the Y direction as the Y axis. "Continuously changing along the X direction" means that when the line is moved to the right along the X axis (from the base to the tip of the arrow in Figure 1), starting from the intersection of the X and Y axes, the filling ratio of the first or second powder cosmetic composition increases or decreases. There may be regions where the filling ratio does not change even when the line is moved along the X-axis, but if the filling ratio changes in a stepwise manner, it is not included in the present invention. In the embodiment shown in Figure 1, more specifically, the filling ratio of the first powder cosmetic composition 11 decreases from left to right in the X direction. Therefore, by moving the application means in the Y direction at a desired position in the X direction and rubbing off the cosmetic, a powder cosmetic with different coverage levels desired by the user can be obtained. In a preferred embodiment, the filling ratio of the first powder cosmetic composition increases or decreases along the X-axis. Embodiments in which the filling ratio increases along the X-axis and then decreases, or decreases and then increases, are undesirable.

[0049] Figure 3 is a conceptual plan view of another multi-color powder-molded cosmetic according to this embodiment. In the multi-color powder-molded cosmetic 2 shown in Figure 3, the first powder cosmetic composition 21 and the second powder cosmetic composition 22 are filled in a different arrangement than in Figure 1.

[0050] The multi-color powder-molded cosmetic composition 2 shown in Figure 3 is filled in a container 24 with a first powder cosmetic composition 21 and a second powder cosmetic composition 22, with a boundary line 23 located at one of the two diagonals when the container is viewed from above. The shape and material of the container 24 may be the same as those of the containers shown in Figures 1 and 2. In Figure 3, the Y direction can be the direction of use, as in Figures 1 and 2, but due to the characteristics of its arrangement, the X direction can also be the direction of use. The user can then obtain effects and effects that are generally the same as those of the multi-color powder-molded cosmetic composition 1 shown in Figures 1 and 2 by moving the applicator in a specific direction of use.

[0051] The arrangement of the first and second powder cosmetic compositions is not limited to the examples shown in Figures 1-3. The first and second powder cosmetic compositions are arranged in such a manner that the desired opacity can be selected in the first direction, and the thickness can be adjusted by rubbing the application means in the second direction perpendicular to it. An example of boundary line design for realizing such an arrangement will be further explained. In a two-dimensional plane viewed from above of a container filled with multicolor powder molded cosmetics, if the direction of use is the Y direction and the direction perpendicular to it is the X direction, the boundary line is provided in such a manner that it is not perpendicular to the Y direction. This is because if the boundary line is provided perpendicular to the Y direction, it will not be possible to continuously change the filling ratio of the first and second powder cosmetic compositions along the Y direction along the X direction. The boundary line may be a straight line or a curve, as shown in Figures 1-3.

[0052] Figures 4 to 8 are conceptual plan views of a multicolor powder-molded cosmetic, showing further examples of the arrangement of the first and second powder cosmetic compositions, as well as the shape of the boundary line. In all of Figures 4 to 8, the first powder cosmetic composition 31 and the second powder cosmetic composition 32 are filled in a manner that has a boundary line 33. In Figures 4 to 8, the X and Y directions are not shown, but in a cosmetic that is roughly rectangular, the direction parallel to the lower edge of the cosmetic is the X direction, the direction parallel to the left edge of the container is the Y direction, and the direction of use is the Y direction. Assuming that a straight line passing through the center of the container and parallel to the direction of use is the center line 35 of the container, in the embodiment of Figure 6, the boundary line 33 crosses the center line 35 once. In the embodiments of Figures 4, 5, 7, and 8, the boundary line 33 crosses the center line 35 twice. Although the center line is not explicitly shown in Figures 1 and 3, assuming a center line as in Figures 4 to 8, in the configuration of Figure 1, boundary line 13 crosses the center line twice, and in the configuration of Figure 3, boundary line 23 crosses the container's center line once. The configuration in which the boundary line crosses the center line twice has the advantage of better operability in the finished product compared to the configuration in which it crosses once, while the configuration in which it crosses once has the advantage of better filling quality during product manufacturing.

[0053] In Figures 4, 6, and 8, the left end of the container contains a portion filled only with the first powder cosmetic composition 31, and in Figures 7 and 8, the right end of the container contains a portion filled only with the second powder cosmetic composition 32. Therefore, in these portions, the filling ratio of the first powder cosmetic composition along the Y direction does not decrease along the X direction. However, near the center of the container, the filling ratio of the first powder cosmetic composition decreases as you move to the right in the X direction, and this is included in the embodiments of the present invention.

[0054] In any of the arrangement examples shown in Figures 1 to 8, the surface of the multicolor powder-molded cosmetic may be embossed (not shown). The embossing may be applied for the purpose of distinguishing the first powder cosmetic composition from the second powder cosmetic composition. In this case, in Figures 1 and 3, which show the cosmetic in plan view, different embossings can be applied to the surfaces of the first powder cosmetic compositions 11 and 21 and the surfaces of the second powder cosmetic compositions 12 and 22. Examples of embossing include different wavy patterns, but are not limited to any particular pattern. Embossing may be applied to only one of the first or second powder cosmetic compositions, and the embossing may be applied solely for aesthetic purposes and not for the purpose of distinguishing the first and second powder cosmetic compositions. The shape of the embossing is also not particularly limited, and any shape including letters or motifs is possible. Instead of embossing, the cosmetic composition may be directly printed on its surface, thereby allowing for distinction between the first powder cosmetic composition and the second powder cosmetic composition. Furthermore, the container may be provided with markings that allow for distinction between the first powder cosmetic composition and the second powder cosmetic composition.

[0055] Next, the multicolor powder-molded cosmetic composition according to this embodiment will be described from the viewpoint of the manufacturing method. The manufacturing method of the multicolor powder-molded cosmetic composition is not particularly limited as long as it is a method that can realize the arrangement of the first powder cosmetic composition and the second powder cosmetic composition, as well as the predetermined form of the boundary line. As an example of a manufacturing method, a manufacturing method including the following steps can be carried out. (a) Steps to prepare the first powder cosmetic composition and the second powder cosmetic composition. (b) A step of placing a partition plate in a container to form a first region for filling with the first powder cosmetic composition and a second region for filling with the second powder cosmetic composition. (c) A step of filling the first region with the first powder cosmetic composition and filling the second region with the second powder cosmetic composition. (d) The process of removing the partition plate and press-molding the first powder cosmetic composition and the second powder cosmetic composition.

[0056] In step (a), the materials are mixed using a mixing device such as a Henschel mixer and then ground using a grinding device such as a hammer mill, in accordance with the general method for preparing powder cosmetics, thereby separately preparing the first powder cosmetic composition and the second powder cosmetic composition.

[0057] In step (b), a partition plate is placed in the container to form a first region for filling with the first powder cosmetic composition and a second region for filling with the second powder cosmetic composition. The placement of the partition plate can be designed to be a preferred form of the boundary line described above with reference to Figures 1 to 9. The first region and the second region are independent and separate regions in which the first powder cosmetic composition and the second powder cosmetic composition do not mix when the partition plate is in place. The partition plate can be manufactured from any material such as paper, plastic, or metal. When manufacturing the multicolor powder molded cosmetic shown in Figure 1, for example, a partition plate in the shape of a flat plate bent into a V shape can be placed in a container that is approximately square in shape when viewed from above. In this way, when viewed from above, the partition plate is placed at the position of boundary line 13 in Figure 1, and the first region and the second region can be formed. Depending on the arrangement of the first powder cosmetic composition and the second powder cosmetic composition, as shown in Figure 1, there may be one first region and multiple second regions, or vice versa.

[0058] In step (c), the first powder cosmetic composition and the second powder cosmetic composition, measured according to the volume of each region, are filled into each region. During this process, the partition plate is held in place without being moved.

[0059] Next, in step (d), the partition plate is removed, bringing the first powder cosmetic composition and the second powder cosmetic composition into contact. Then, both are simultaneously pressure-molded. The pressure molding conditions are as follows: a semi-automatic press is used, with a press pressure of 20-25 kgf / cm². 2 It can be molded using this method. By using a desired embossing die during pressure molding, the desired embossing can be achieved. Molding methods include dry molding and wet molding, but the method is not particularly limited.

[0060] As an additional step, a process can be carried out in which markings distinguishing the first powder cosmetic composition from the second powder cosmetic composition can be printed on the surface of the molded multi-color powder cosmetic composition. Alternatively, markings distinguishing the first powder cosmetic composition from the second powder cosmetic composition can be applied to the rim of the container containing each cosmetic composition, or to another container that further contains these containers.

[0061] According to the multicolor powder-molded cosmetic according to embodiment (A), in which a first powder cosmetic composition and a second powder cosmetic composition are separately filled, two different cosmetic compositions are filled in a single container in a predetermined manner with a boundary line, making it possible to adjust the finish effect of the cosmetic and providing a highly convenient cosmetic. Furthermore, since two cosmetic compositions with different opacities are arranged with a boundary line, the appearance is also excellent.

[0062] (B) Gradient Next, another embodiment of the arrangement of the first powder cosmetic composition and the second powder cosmetic composition will be described. According to this other embodiment, the first powder cosmetic composition and the second powder cosmetic composition are mixed without boundaries in a single container, forming a gradient in one direction within the container. More specifically, forming a gradient means that the concentration of opacity powder increases or decreases from one end to the other in a first direction of the single container, and the concentration of opacity powder does not change from one end to the other in a second direction perpendicular to the first direction, in which case the first powder cosmetic composition (i) and the second powder cosmetic composition (ii) are filled. Preferably, this gradient is a natural gradient that is blurred to the extent that the molded regions of the first powder cosmetic composition (i) and the second powder cosmetic composition (ii) are indistinguishable.

[0063] Now, let's refer to Figure 1 again. First, we will explain the embodiment that forms a gradient in one direction from the perspective of the manufacturing method. An example of a manufacturing method for a multicolor powder molded cosmetic that forms a gradient includes the following steps. (1) Steps to prepare the first powder cosmetic composition and the second powder cosmetic composition. (2) A step of placing a partition plate in a container to form a first region for filling with the first powder cosmetic composition and a second region for filling with the second powder cosmetic composition. (3) A step of filling the first region with the first powder cosmetic composition and filling the second region with the second powder cosmetic composition. (4) Remove the partition plate and mix the first powder cosmetic composition and the second powder cosmetic composition in a direction parallel to the direction of use. (5) Process of pressure molding the mixed composition

[0064] Steps (1) to (3) are carried out in the same manner as steps (a) to (c) of embodiment (A). The arrangement of the first powder cosmetic composition and the second powder cosmetic composition, as well as the design of the boundary line, are also carried out in the same manner as in embodiment (A), by determining a second direction (Y direction) parallel to the direction of use and a first direction (X direction) perpendicular to the second direction, and arranging them so that the filling ratio of the first powder cosmetic composition and the second powder cosmetic composition along the Y direction changes continuously in the X direction.

[0065] In step (4), the partition plate is removed in the same manner as in step (d) of embodiment (A). Next, before pressure molding, a mixing step is performed to form a gradient. The mixing is carried out with the first powder cosmetic composition and the second powder cosmetic composition arranged as shown in Figure 1, and the two compositions are mixed only in the Y direction, i.e., the direction of use, and no mixing operation is performed in the X direction. More specifically, for example, a fork-shaped or comb-shaped mixing tool is inserted into the filled composition until its tip touches the bottom surface. Next, in the plan view of Figure 1, the mixing tool is moved back and forth multiple times in the Y direction from the upper edge to the lower edge of the container 14. At this time, it is preferable that the mixing tool is moved back and forth so as not to swing in the X direction.

[0066] The mixing in step (4) mixes the first powder cosmetic composition and the second powder cosmetic composition in the Y direction, resulting in a composition in which the first and second powder cosmetic compositions are mixed substantially uniformly without boundaries in the Y direction. In other words, at a certain point in the X direction, the concentration of opacity powder does not change from one end to the other in the Y direction, which is the direction of use. The concentration of opacity powder referred to here is the total concentration of the first and second opacity powders. Furthermore, it is preferable that the cosmetic composition be substantially uniformly mixed in the depth direction of the container, which can be achieved in step (4) by performing uniform mixing in the depth direction as well.

[0067] In step (4), no mixing operation is performed in the X direction. Therefore, the change in the filling ratio of the first powder cosmetic composition and the second powder cosmetic composition along the X direction is based on the arrangement design described in aspect (A). The filling ratio of the first powder cosmetic composition decreases or increases in the X direction (including aspects in which there are parts that do not increase or decrease and remain unchanged). In other words, the filling ratio of the first powder cosmetic composition increases or decreases from one end to the other in the X direction, which is perpendicular to the Y direction, which is the direction of use. To put it another way, the arrangement is such that the total concentration of the first opacifying powder and the second opacifying powder increases or decreases from one end to the other in the X direction.

[0068] The method of using the multicolor powder-molded cosmetic in embodiment (B) that forms a gradient may be substantially the same as the method of use in embodiment (A). A desired coverage area that changes in the X direction is selected, and the cosmetic is attached to the application means by rubbing it in the Y direction, which is the direction of use. The cosmetic attached to the application means can then be applied to the user's skin.

[0069] In this embodiment as well, embossing and other markings can be provided on the multi-color powder-molded cosmetic. Figure 9 shows a conceptual cross-sectional view of an example of a multi-color powder-molded cosmetic with embossing in embodiment (B) which forms a gradient. The multi-color powder-molded cosmetic in Figure 9 is an example of a cosmetic obtained by filling a first powder cosmetic composition and a second powder cosmetic composition in the arrangement shown in Figure 1 according to steps (1) to (3), then mixing in the Y direction in Figure 1 according to step (4), and then pressure molding using an embossing mold in step (5). The surface of the multi-color powder-molded cosmetic 4 is provided with a wavy pattern embossing 47, the width of which narrows towards the right in the X direction. Although not shown, the width of the embossing 47 is constant in the Y direction. In the embodiment shown in Figure 9, the mixing in step (4) results in the first powder cosmetic composition and the second powder cosmetic composition being mixed without a boundary, and the total concentration of the first opacity powder and the second opacity powder in the mixture 46 decreases from left to right in the X direction (concentration and composition are not shown). As shown in the figure, by changing the width of the emboss 47 along the X direction, it is possible to visually display the change in opacity. In Figure 9, it can be recognized that the wider the width of the emboss 47, the higher the total concentration of the first opacity powder and the second opacity powder in that region. In other words, the emboss 47 allows for the visual recognition of regions with higher coverage suitable for thick application and regions with transparency suitable for thin application. Note that the emboss used to visually display the level of opacity is not limited to a wavy pattern, but can be any emboss, such as the size of a specific motif. Similar functionality can also be achieved by printed markings other than embossing or markings on the container.

[0070] According to embodiment (B), since the concentration of the opacity powder along the Y direction is substantially uniform, when moving the coating means in the Y direction, it is not necessarily required to move the coating means from near the lower edge to near the upper edge of the container 14 in Figure 1. For example, by moving the coating means a small distance in the Y direction within the center of the container, a cosmetic of the desired composition can be uniformly applied to the coating means. Therefore, in embodiment (B), a more beautiful finish can be expected in a shorter time while maintaining the adjustment function. [Examples]

[0071] The present invention will be described in more detail below with reference to examples. However, the present invention is not limited to the following examples.

[0072] Mix the components shown in the table below to prepare the first powder cosmetic composition (i) and the second powder cosmetic composition (ii), and then use a semi-automatic press with a pressing pressure of 24 kgf / cm². 2 Multicolor powder-molded cosmetics (foundations) of the examples shown in Figure 1 (hereinafter referred to as (A)) and arrangement B (hereinafter referred to as (B)), which is a gradient arrangement based on arrangement A, were manufactured by pressure molding. Similarly, for the comparative examples, two powder cosmetic compositions (a) and (b) that did not satisfy the composition criteria of (i) and (ii) of the present invention were prepared and manufactured by pressure molding under the same conditions as above to produce the comparative examples of multicolor powder-molded cosmetics.

[0073] The functionality of the obtained multi-color powder-molded cosmetics was evaluated. For the evaluation of the finish adjustment function, the contents of powder cosmetic composition (i), (ii), a, or b were taken out by rubbing 3 to 5 times with a sponge, and then the contents were applied to the inner forearm of the subject by rubbing this sponge 3 times. The evaluation of finish operability was performed in the same manner as above. For both the gradient type and the bordered type, the contents were applied to three locations: the left and right ends and the center, and the finish adjustment function and finish operability were evaluated. The bordered type (A) was taken out by 5 rubs, and the gradient type (B) was taken out by 3 rubs.

[0074] The finish adjustment function was evaluated as follows. Here, the finish adjustment function refers to the function that allows you to change the degree of thick or thin coating. ◎ The difference in opacity between (i) and (ii), or between (a) and (b), is significant, allowing for greater control over thickness (thick or thin application). ○ The difference in opacity between (i) and (ii), or between (a) and (b), is moderate, and adjustments to thick or thin coatings are possible. ○△ The difference in opacity between (i) and (ii), or between (a) and (b), is small, and some degree of adjustment between thick and thin application is possible. △ The difference in opacity between (i) and (ii), or between (a) and (b), is small, and slight adjustment of thick or thin application is possible. × There is almost no difference in opacity between (i) and (ii), or between (a) and (b), making it impossible to adjust for thick or thin application.

[0075] The evaluation of the finish and operability was conducted as follows. Here, finish and operability refers to the ease of finishing. ○ (i) and (ii), or (a) and (b), the finished product is easy to work with. ○△ (i) and (ii), or (a) and (b) can be processed to complete the final result.

[0076] The appearance was observed visually, and the evaluation criteria were as follows: For the type with a boundary line (A), the difference between the two appearance colors distinguished by the boundary line was evaluated visually, and for the gradient type (B), the difference between the appearance colors at the left and right ends of Figure 1 was evaluated visually. ○ There is a difference in the appearance color between (i) and (ii), or between (a) and (b). ○△ There is a certain degree of difference in the appearance color between (i) and (ii), or between (a) and (b). △ The difference in appearance color between (i) and (ii), or between (a) and (b) is small. △× There is almost no difference in the appearance color between (i) and (ii), or between (a) and (b).
