According to one embodiment, the present invention relates to a multicolored powder molded cosmetic. In the multicolor powder molded cosmetic of this embodiment, a powder cosmetic containing the following components (i) and (ii) is filled and molded into a single container.
(i) A first powder cosmetic composition containing 6% by mass or more of a first hiding powder with a refractive index of 1.7 or more (ii) Containing a second hiding powder with a refractive index of 1.7 or more a second powder cosmetic composition, wherein the content ratio of the second masking powder in the second powder cosmetic composition is the same as the first masking powder in the first powder cosmetic composition; A second powder cosmetic composition having a content ratio of 1/2 or less of the powder content.

Here, the multicolor powder molded cosmetic refers to a cosmetic in which two or more powder cosmetic compositions having different tones are integrally molded. "Different in color tone" means that the powder cosmetic composition satisfies the relationship between the contents of the concealing powder defined in (i) and (ii) above. As used herein, a powder cosmetic composition refers to a cosmetic composition in which the powder component is 80% by mass or more, preferably 85% by mass or more, when the mass of the entire composition is 100%. shall be. The compositions (i) and (ii) constituting each cosmetic will be explained below.

(i) First powder cosmetic composition The first powder cosmetic composition is a composition containing 6% by mass or more of the first hiding powder having a refractive index of 1.7 or more. The first powder cosmetic composition may typically be a powder foundation, and may be a powder foundation with higher hiding power than the second powder cosmetic composition described below.

The first powder cosmetic composition contains the first concealing powder as an essential component. In this embodiment, the opaque powder refers to a powder having a refractive index of 1.7 or more. In this specification, the concealing powder contained in the first powder cosmetic composition is referred to as the first concealing powder. The refractive index of the first opaque powder is preferably 2.0 or more, more preferably 2.5 or more. Among the opaque powders, examples of powders with a refractive index of about 1.7 include boron nitride, and examples of powders with a refractive index of about 2.0 include zinc oxide, which has a refractive index of about 2.5. Examples of the powder include, but are not limited to, titanium oxide. In addition, any compound having a refractive index of 1.7 or more can be used as the hiding powder, and the type of compound is not limited. The first opaque powder may be a mixture of two or more different powders each having a refractive index of 1.7 or more.

The shape of the first concealing powder may be any shape including a tubular shape, a plate shape, a needle shape, a spherical shape, a petal shape, an irregular shape, or a combination thereof. The average particle diameter of the first concealing powder is not particularly limited, and may have an average particle diameter commonly used in powder cosmetics that require concealing properties, such as powder foundations.

Note that the pearl agent is not included in the concealing powder in the present invention. Pearling agents are generally made of mica (sericite) coated with titanium oxide. Pearl materials that have a layer of titanium oxide on the surface may have a refractive index of 1.7 or higher, but depending on the pearl agent added, the pearlescent feel, luster, or metallic feel may appear too much, so it is not a pearl agent. This is because it cannot be expected to have the same hiding power as a powder with a refractive index of 1.7 or higher.

The first concealing powder is contained in an amount of 6% by mass or more when the total mass of the first powder cosmetic composition is 100%. This is to give the first powder cosmetic composition a higher hiding power than the second powder cosmetic composition. As long as the content of the first hiding powder is 6% by mass or more, it may be, for example, 8% by mass or more, or 10% by mass or more, and the content is set as appropriate depending on the purpose and use. can do. On the other hand, the upper limit of the content of the first concealing powder can be, for example, about 25% by mass. By increasing the content of the first opaque powder, it is possible to maximize the opacity and prevent stains and dullness. On the other hand, if the content of the first opaque powder is too large, it may be difficult to adhere to the powder and cause difficulty in usability.

The first powder cosmetic composition may contain any powder component other than the first concealing powder, and the optional powder component may include a powder that does not meet the definition of the first concealing powder. There may be constitutional powders or colored powders.

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

As the colored powder, pigments normally used in foundations can be used, and may include, but are not limited to, colored pigments such as titanium oxide, iron oxide, titanium mica, and organic tar pigments. Titanium mica can be used as a pearling agent. Colored powders can be included in the amounts normally included in cosmetics.

The first powder cosmetic composition can further contain arbitrary components depending on the purpose and use. Optional ingredients include binders, surfactants, antioxidants, emulsifiers, dispersants, preservatives, humectants, polyhydric alcohols, lower alcohols, sugars, ultraviolet absorbers, whitening agents, skin activators, and blood circulation promoters. The composition may also contain optional ingredients such as drugs such as anti-seborrheic agents, anti-inflammatory agents, astringents, refreshing agents, and perfumes.

The first powder cosmetic composition may also contain a dispersant. Dispersants include polyglyceryl-10 decaisostearate and sorbitan sesquiisostearate, but are not limited to specific compounds.

The first powder cosmetic composition may also contain an ultraviolet absorber. Examples of ultraviolet absorbers include ethylhexyl methoxycinnamate, but are not limited to specific compounds.

The first powder cosmetic composition may include spherical powder to improve usability. Examples of the 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/dimethacrylate) glycol) crosspolymers, but are not limited to specific compounds.

An oily component or water can also be used as a binder in the first powder cosmetic composition. As the oily component, a liquid oil that is liquid at room temperature to the cosmetic manufacturing temperature (25 to 80° C.) can be used. For example, hydrocarbons such as liquid paraffin and squalane, isopropyl myristate, octyldodecyl myristate, di-2-ethylhexyl sebacate, neopentyl glycol di-2-ethylhexanoate, neopentyl glycol dicaprate, and tri-2-ethylhexanoic acid. Esters such as glyceryl, diglyceryl triisostearate, pentaerythritol tetra-2-ethylhexanoate, dipentaerythritol-2-ethylhexanoate, trimethylolpropane tri-2-ethylhexanoate, diisostearyl malate; olive oil; Oils and fats such as castor oil; Higher fatty acids such as isostearic acid and oleic acid; Higher alcohols such as isostearyl alcohol and oleyl alcohol; Silicone oils such as dimethylpolysiloxane, methylphenylpolysiloxane, and decamethylcyclopentasiloxane. Can be mentioned. As the oily component in the present invention, one or more of the above may be arbitrarily selected and used. A mixture of semi-solid oil or solid oil with the above oily component may also be used. As the semi-solid oil, for example, vaseline, cholesteryl hydroxystearate, hydrogenated castor oil stearate, dipentaerythritol fatty acid (12-hydroxystearic acid, stearic acid, rosin acid, etc.) ester, etc. can be used. In addition, solid oils include hydrogenated oil, oils and fats such as Japanese wax; hydrocarbons such as ceresin, microcrystalline wax, paraffin wax, and polyethylene wax; waxes such as beeswax, candelilla wax, and carnauba wax; stearic acid, and behen Higher fatty acids such as acids; higher alcohols such as cetanol, etc. may be used. The powder cosmetic of the present invention may further contain an emulsifying composition such as a water-in-oil emulsifying composition or an oil-in-water emulsifying composition as another component. Note that the content of the oily component is preferably not more than 20% by mass, and can be about 5 to 15% by mass, when the total mass of the first powder cosmetic composition is 100%.

(ii) Second powder cosmetic composition The second powder cosmetic composition contains a second hiding powder having a refractive index of 1.7 or more, and the second powder cosmetic composition contains a second hiding powder with a refractive index of 1.7 or more. The content ratio of the concealing powder is 1/2 or less of the content ratio of the first concealing powder in the first powder cosmetic composition.

The second powder cosmetic composition may also typically be a powder foundation, and may be a powder foundation with lower hiding power than the first powder cosmetic composition.

The second powder cosmetic composition also contains a concealing powder like the first powder cosmetic composition. In this specification, the concealing powder contained in the second powder cosmetic composition is referred to as the second concealing powder. The definition and options for the second opaque powder are the same as for the first opaque powder. Therefore, the composition of the second hiding powder may be the same as or different from the composition of the first hiding powder. When the compositions are different, it is preferable that the refractive index of the second opaque powder is smaller than the refractive index of the first opaque powder.

The shape and average particle diameter of the second hiding powder can also be selected from the options exemplified for the first hiding powder. Therefore, the shape and average particle diameter of the second concealing powder may be the same as or different from the shape and average particle diameter of the first concealing powder.

The content of the second concealing powder in the second powder cosmetic composition is 1/2 or less of the content of the first concealing powder in the first powder cosmetic composition. This is because it is possible to ensure a difference in hiding power between the first powder cosmetic composition and the second powder cosmetic composition, and to clarify the difference in functionality. Note that the content of the second concealing powder in the second powder cosmetic composition may be zero. Therefore, in this case, it can be said that the second powder cosmetic composition does not contain the concealing powder.

The second powder cosmetic composition may contain any component other than the second concealing powder. Any component can be selected from the same selection of any component in the first powder cosmetic composition. In one embodiment, the substance used as an optional ingredient in the second powder cosmetic composition may be the same as the substance used as an optional ingredient in the first powder cosmetic composition. In this case, among the optional components, the content of substances other than the corporeal powder may also be the same. The amount of the extender powder added can be increased or decreased as appropriate to adjust the content (balance) of each component.

In the multicolor powder-molded cosmetic according to the present embodiment, the first powder cosmetic composition and the second powder cosmetic composition are filled and molded in a single container to constitute the powder cosmetic. There is.

In the multicolored powder-molded cosmetic, the first powder cosmetic composition and the second powder cosmetic composition may be filled in (A) separately with a boundary line; (B) ) There may be an embodiment in which the ingredients are mixed in a gradation. Each will be explained below.

(A) Separately filled with a boundary line According to one embodiment, the first powder cosmetic composition and the second powder cosmetic composition are filled adjacent to each other, and the first powder cosmetic composition is filled with the first powder cosmetic composition. The powder cosmetic composition has a boundary line that distinguishes the filling area between the cosmetic powder 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 explained with reference to the drawings. FIG. 1 is a conceptual plan view of the multicolor powder molded cosmetic of this embodiment, and FIG. 2 is a conceptual cross-sectional view taken along the line AA in FIG.

In the multicolor powder molded cosmetic 1 shown in FIGS. 1 and 2, a first powder cosmetic composition 11 and a second powder cosmetic composition 12 are separately filled in a container 14. In FIGS. 1 and 2, a boundary line 13 indicates a 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 have a boundary line between them. This refers to the fact that two powder cosmetic compositions 12 are adjacent but do not substantially mix and exist separately, and when the cross section shown in FIG. 2 is analyzed, it is possible to show a line where the composition changes. It means that it is a mode. Therefore, however, the first powder cosmetic composition 11 and the second powder cosmetic composition 12 are in contact with each other, rather than any substance or partition existing at the boundary.

The illustrated container 14 has a square shape with four rounded corners when viewed from above, and contains the first powder cosmetic composition 11 and the second powder cosmetic composition 12. It has a depth that can be accommodated. Container 14 may be made of metal, plastic, or any material whose properties do not change under manufacturing conditions.

The volume ratio between the filling amount of the first powder cosmetic composition and the filling amount of the second powder cosmetic composition is not particularly limited, and can be appropriately set depending on the purpose and use. For example, the ratio may be about 2:8 to 8:2, or 4:6 to 6:4, and the volume may be the same, but the ratio is not limited to a specific one.

Next, the multicolored powder molded cosmetic 1 will be explained from the viewpoint of how to use it. In this specification, the direction indicated by arrow X in FIG. 1 is referred to as a first direction or X direction, and the direction indicated by arrow Y is referred to as a second direction or Y direction. The second direction is defined as the "usage direction." The usage direction is the direction in which the application means is moved in order to adhere the cosmetic to the application means when using the multicolor powder molded cosmetic 1. By moving the applicator in a predetermined "direction of use" and rubbing off the multicolored powder molded cosmetic 1, it becomes possible to adjust thick application or thin application, which is the objective of the present invention.

Depending on the embodiment of the multicolor powder-molded cosmetic 1, the direction of use can be indicated on the container, or it can be indicated on the cosmetic itself by embossing or printing. Alternatively, it can be displayed on an instruction manual that may be attached to the container or on a protective film. In FIG. 1, the direction of use is shown by illustrating a substantially rectangular container, but even if the container is polygonal, circular, or elliptical, by providing an indication indicating the direction of use, the first direction and the second direction can be shown. Two directions can be determined, making the above method of use possible.

When using the multicolor powder-molded cosmetic 1, the user brings the application means into contact with the multicolor powder-molded cosmetic 1 and moves it in the second direction, thereby allowing the cosmetic to adhere to the application means. can. The application means may be a foundation sponge, a 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 multicolor powder-molded cosmetic 1 in FIG. 1, that is, on the proximal end side of the arrow It can be attached. This allows the user to achieve thick application with emphasis on coverage. On the other hand, when moving the application means in the Y direction at the right end of the multicolor powder-molded cosmetic 1 in FIG. 1, that is, on the tip side of the arrow can be done. As a result, the user can achieve a thin application that emphasizes the feel of bare skin. When the application means is moved in the Y direction in the middle part of the container, the first powder cosmetic composition 11 and the second powder cosmetic composition 12 can be adhered to the application means to the same extent. Thereby, the user can obtain a medium covering power. In addition, in this embodiment, when the application means is moved in the Y direction to scrape off the cosmetic, it is preferable to move it from the vicinity of the lower edge of the container to the vicinity of the upper edge in FIG. It is preferable to move the cosmetic to the application means.

Referring to FIG. 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" is defined as the filling ratio of the first powder cosmetic composition and the second powder cosmetic composition in a plan view of the filled part of the container filled with the multicolor powder molded cosmetic. In a two-dimensional plane, the lower edge of the container parallel to the X direction is the X axis, the left edge of the container parallel to the Y direction is the Y axis, and when a straight line parallel to the Y axis is extrapolated, It can be expressed as the ratio of the length across the first powder cosmetic composition and the length across the second powder cosmetic composition. "Changes continuously along the X direction" means that the straight line starts at the intersection of the X and Y axes and moves to the right along the X axis (from the base to the tip of the arrow in Figure 1). This means that when moved, the filling ratio of the first or second powder cosmetic composition increases or decreases. Although there may be a region in which the filling ratio does not change even if the straight line is moved along the X-axis, a case where the filling ratio changes stepwise is not included in the present invention. In the embodiment shown in FIG. 1, more specifically, the filling ratio of the first powder cosmetic composition 11 decreases from the left side to the right side in the X direction. Therefore, by moving the applicator in the Y direction at a desired position in the X direction and rubbing off the cosmetic, it is possible to obtain a powder cosmetic having a different covering power as desired by the user. In a preferred embodiment, the filling ratio of the first powder cosmetic composition increases or decreases along the X axis. It is not preferable that the filling ratio increases along the X-axis and then decreases, or decreases once and then increases.

FIG. 3 is a conceptual plan view of another multicolored powder molded cosmetic of this embodiment. The multicolor powder molded cosmetic 2 shown in FIG. 3 is filled with a first powder cosmetic composition 21 and a second powder cosmetic composition 22 in a different arrangement from that in FIG. 1.

The multicolor powder-molded cosmetic 2 shown in FIG. It is filled in such a manner that it has a border line 23 at a position corresponding to one of the diagonals. The shape and material of container 24 may be similar to the container shown in FIGS. 1 and 2. In FIG. 3, the Y direction can be used as the usage direction as in FIGS. 1 and 2, but due to the characteristics of the arrangement, the X direction can also be used as the usage direction. By moving the applicator in a specific direction of use, the user can obtain substantially the same effects as the multicolored powder molded cosmetic 1 shown in FIGS. 1 and 2.

The arrangement of the first powder cosmetic composition and the second powder cosmetic composition is not limited to the examples shown in FIGS. 1 to 3. A first powder cosmetic composition in a manner that allows adjustment of thick application or thin application by selecting a desired hiding property in a first direction and rubbing the application means in a second direction perpendicular to the first direction; and a second powder cosmetic composition. A design example of a boundary line for realizing such an arrangement will be further described. In a two-dimensional plane in which a container filled with a multicolored powder molded cosmetic is viewed from above, the direction of use is the Y direction, and the direction perpendicular to this is the X direction, and the boundary line is provided in a manner that is not perpendicular to the Y direction. It will be done. When the boundary line is provided orthogonally to the Y direction, the filling ratio of the first powder cosmetic composition and the second powder cosmetic composition along the Y direction is continuously changed along the X direction. This is because it cannot be done. The boundary line may be a straight line, as shown in FIGS. 1-3, or a curved line.

FIGS. 4 to 8 are conceptual diagrams of a multicolor powder-molded cosmetic, showing further examples of the arrangement of the first powder cosmetic composition and the second powder cosmetic composition, as well as the shape of the boundary line. FIG. In each of FIGS. 4 to 8, the first powder cosmetic composition 31 and the second powder cosmetic composition 32 are filled in such a manner that they have a boundary line 33. Although the X and Y directions are not shown in FIGS. 4 to 8, in the case of a substantially rectangular cosmetic, the X direction is the direction parallel to the lower edge of the cosmetic, and the direction parallel to the left edge of the container. The direction of use is the Y direction. Assuming that a straight line passing through the center of the container and parallel to the usage direction is the center line 35 of the container, in the embodiment of FIG. 6, the boundary line 33 crosses the center line 35 once. In the embodiments of FIGS. 4, 5, 7, and 8, the boundary line 33 crosses the center line 35 twice. Although the center line is not clearly shown in FIGS. 1 and 3, if a center line is assumed as in FIGS. 4 to 8, in the embodiment of FIG. 1, the boundary line 13 crosses the center line twice. , in the embodiment of FIG. 3, the boundary line 23 crosses the container centerline once. The mode in which the boundary line crosses the center line twice has the advantage that the finished operability is better than the mode in which it crosses the center line once, and the mode in which it crosses the center line once has the advantage that filling is more appropriate when producing the contents. be.

In addition, in FIGS. 4, 6, and 8, there is a part filled with only the first powder cosmetic composition 31 at the left end of the container, and in FIGS. 7 and 8, there is a part filled with only the first powder cosmetic composition 31, There is a portion filled only with the second powder cosmetic composition 32. Therefore, in these parts, 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 toward the right in the X direction, which is included in the aspect of the present invention.

In any of the arrangement examples shown in FIGS. 1 to 8, the surface of the multicolor powder molded cosmetic may be embossed (not shown). The embossing may be provided for the purpose of distinguishing the first powder cosmetic composition from the second powder cosmetic composition. In this case, in FIGS. 1 and 3 when the cosmetic is viewed from above, different embossing may 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. I can do it. Examples of embossing may include different wavy patterns, but are not limited to any particular pattern. Only one of the first powder cosmetic composition and the second powder cosmetic composition may be embossed to distinguish between the first powder cosmetic composition and the second powder cosmetic composition. The embossing may be applied solely for the purpose of design and not for the purpose of design. The shape of the embossing is also not particularly limited, and any shape including letters and motif shapes is possible. Instead of embossing, a printed display may be directly attached to the surface of the cosmetic, and this may be an embodiment in which the first powder cosmetic composition and the second powder cosmetic composition can be distinguished. Furthermore, the container may be provided with an indication that allows the first powder cosmetic composition and the second powder cosmetic composition to be distinguished.

Next, the multicolored powder molded cosmetic according to the present embodiment will be explained from the viewpoint of the manufacturing method. The method for producing a multicolored powder-molded cosmetic is a method capable of realizing the arrangement of the first powder cosmetic composition and the second powder cosmetic composition as well as a predetermined aspect of the boundary line. If so, there are no particular limitations. As an example of the manufacturing method, a manufacturing method including the following steps can be implemented.
(a) A step of preparing a first powder cosmetic composition and a second powder cosmetic composition. (b) A first step of arranging a partition plate in a container and filling the first powder cosmetic composition. and a second region filled with a second powder cosmetic composition. (c) Filling the first region with the first powder cosmetic composition and filling the second region with the second powder cosmetic composition. (d) Step of removing the partition plate and pressure-molding the first powder cosmetic composition and the second powder cosmetic composition.

In step (a), according to a general method for preparing powder cosmetics, the materials are mixed using a mixing device such as a Henschel mixer and pulverized using a pulverizing device such as a hammer mill to obtain a first powder. A cosmetic composition and a second powder cosmetic composition are prepared separately.

In step (b), a partition plate is arranged in the container to form a first region filled with the first powder cosmetic composition and a second region filled with the second powder cosmetic composition. The arrangement of the partition plates can be designed to provide the preferred embodiments of the boundaries described above with reference to FIGS. 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 with each other when the partition plate is placed. Dividers can be made of any material, such as paper, plastic, or metal. When manufacturing the multicolor powder molded cosmetic shown in FIG. 1, for example, a partition plate in the form of a flat plate bent into a V-shape can be placed in a container that is approximately square in plan view. Thereby, when viewed from above, the partition plate is arranged at the position of the boundary line 13 in FIG. 1, and a first region and a second region can be formed. Depending on the arrangement of the first powder cosmetic composition and the second powder cosmetic composition, as shown in FIG. 1, there may be one first area and multiple second areas, or vice versa. There is also.

In step (c), each region is filled with a first powder cosmetic composition and a second powder cosmetic composition measured according to the volume of each region. During this time, hold the partition plate without moving it.

Next, in step (d), the partition plate is removed to bring the first powder cosmetic composition and the second powder cosmetic composition into contact with each other. Then, both are pressure molded at the same time. The pressure molding can be performed using a semi-automatic press machine at a press pressure of 20 to 25 kgf/cm ² . By using a desired embossing mold during pressure molding, desired embossing can be performed. Examples of the molding method include dry molding and wet molding, but the method is not particularly limited.

As an additional step, a step of printing on the surface of the multicolored powder-molded cosmetic after molding is performed to distinguish between the first powder cosmetic composition and the second powder cosmetic composition. be able to. In addition, markings to distinguish between the first powder cosmetic composition and the second powder cosmetic composition are provided on the edge of the container containing each cosmetic composition or on another container that further contains this container. It can also be attached.

According to the multicolored powder molded cosmetic in which the first powder cosmetic composition and the second powder cosmetic composition are separately filled according to aspect (A), two different types can be stored in a single container. Since the cosmetic composition is filled in a predetermined manner with boundaries, it is possible to adjust the finish effect of the makeup, and it is possible to provide a highly convenient cosmetic. Furthermore, the cosmetic compositions having two different concealing properties are arranged with a boundary line, and the appearance is also excellent.

(B) Gradation Next, another embodiment of the arrangement of the first powder cosmetic composition and the second powder cosmetic composition will be described. According to another embodiment, the first powder cosmetic composition and the second powder cosmetic composition are mixed without boundaries in a single container, and a gradation is created in one direction within the container. is forming. More specifically, forming a gradation means that the concentration of the opaque powder increases or decreases from one end of the single container in the first direction to the other end, and from one end of the single container in the second direction perpendicular to the first direction. The first powder cosmetic composition (i) and the second powder cosmetic composition (ii) are filled in such a manner that the concentration of the concealing powder does not change toward the other end. means. This gradation is preferably a natural gradation that is blurred to such an extent that the molded areas of the first powder cosmetic composition (i) and the second powder cosmetic composition (ii) cannot be distinguished.

Referring again to FIG. An aspect of forming a gradation in one direction will first be described from the viewpoint of a manufacturing method. An example of a method for producing a multicolored powder molded cosmetic that forms a gradation includes the following steps.
(1) A step of preparing a first powder cosmetic composition and a second powder cosmetic composition. (2) A first step of arranging a partition plate in a container and filling the first powder cosmetic composition. and a second region filled with a second powder cosmetic composition. (3) Filling the first region with the first powder cosmetic composition and filling the second region with the second powder cosmetic composition. (4) Step of removing the partition plate and mixing the first powder cosmetic composition and the second powder cosmetic composition in a direction parallel to the direction of use (5) After mixing A process of pressure molding the composition of

Steps (1) to (3) are carried out in the same manner as steps (a) to (c) of embodiment (A). Similarly to the embodiment (A), the arrangement of the first powder cosmetic composition and the second powder cosmetic composition and the design of the boundary line are also arranged in the second direction (Y direction) parallel to the direction of use. , a first direction (X direction) perpendicular to the second direction, and the filling ratio of the first powder cosmetic composition and the second powder cosmetic composition along the Y direction is determined in the X direction. arranged so that it changes continuously.

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 gradation. The mixing involves mixing the two types of compositions only in the Y direction, that is, in the direction of use, with the first powder cosmetic composition and the second powder cosmetic composition arranged as shown in FIG. The mixing operation is not performed in the X direction. More specifically, for example, a fork-shaped or comb-shaped mixing tool is inserted into the filled composition until the tip touches the bottom surface. Next, in the plan view of FIG. 1, the mixing tool is moved back and forth in the Y direction multiple times from the upper edge to the lower edge of the container 14. At this time, it is preferable to reciprocate the mixing tool so that it does not swing in the X direction.

By mixing in step (4), the first powder cosmetic composition and the second powder cosmetic composition are mixed in the Y direction, and the first powder cosmetic composition and the second powder cosmetic composition are mixed. The composition can be made into a composition in which the components are substantially uniformly mixed without boundaries in the Y direction. That is, at a certain point in the X direction, the concentration of the concealing powder does not change from one end to the other end in the Y direction, which is the usage direction. The concentration of the concealing powder here is the total concentration of the first concealing powder and the second concealing powder. Further, it is preferable that the cosmetic composition has a composition that is substantially uniformly mixed even in the depth direction of the container, and this can be achieved by uniformly mixing also in the depth direction in step (4).

In the mixing step (4), the mixing operation in the X direction is not performed, so 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 layout design explained in aspect (A), the filling ratio of the first powder cosmetic composition decreases or increases in the X direction (there are some parts that do not increase or decrease and do not change). (including aspects). That is, the filling ratio of the first powder cosmetic composition increases or decreases from one end to the other end in the X direction perpendicular to the Y direction, which is the usage direction. In other words, they are arranged in such a manner that the total concentration of the first concealing powder and the second concealing powder increases or decreases from one end to the other end in the X direction.

The method of using the multicolored powder molded cosmetic of the embodiment (B) that forms a gradation may be substantially the same as the method of using the multicolor powder molded cosmetic of the embodiment (A). By selecting a desired coverage area that changes in the X direction and rubbing the applicator in the Y direction, which is the direction of use, the cosmetic is adhered to the applicator. The cosmetic applied to the application means can then be applied to the user's skin.

Also in this embodiment, a display such as embossing can be provided on the multicolor powder molded cosmetic. FIG. 9 shows a conceptual cross-sectional view of an example of an embossed multicolored powder-molded cosmetic in the embodiment (B) that forms a gradation. The multicolored powder-molded cosmetic of FIG. 9 is obtained by filling the first powder cosmetic composition and the second powder cosmetic composition in the arrangement shown in FIG. 1 according to steps (1) to (3). This is an example of a cosmetic obtained by mixing in the Y direction of FIG. 1 in step (4) and then press-molding using an embossing mold in step (5). Embosses 47 with a wavy pattern are provided on the surface of the multicolored powder molded cosmetic 4, and the width thereof becomes narrower toward the right side in the X direction. Although not shown, the width of the embossing 47 is constant in the Y direction. In the embodiment shown in FIG. 9, the first powder cosmetic composition and the second powder cosmetic composition are mixed without boundaries in the mixing in step (4), and the first concealment in the mixture 46 is The total concentration of the concealing powder and the second concealing powder decreases from the left side to the right side in the X direction (the concentration and composition are not shown). Then, as shown in the figure, by changing the width of the embossing 47 along the X direction, it is possible to visually display changes in the height of concealment. In FIG. 9, it can be recognized that the wider the width of the embossing 47 is, the higher the total concentration of the first concealing powder and the second concealing powder is. That is, the embossment 47 makes it possible to visually recognize areas with higher coverage suitable for thick coating and transparent areas suitable for thin coating. Note that the emboss that visually indicates the degree of concealment is not limited to a wavy pattern, and may be any emboss that has a specific motif, such as a large or small one. A similar function can also be achieved by printed markings other than embossing or markings attached to the container.

According to the embodiment (B), since the concentration of the concealing powder along the Y direction is substantially uniform, when moving the application means in the Y direction, the lower edge of the container 14 in FIG. It is not necessary to move the application means from the vicinity to the vicinity of the upper edge. For example, by simply moving the applicator by a small width in the Y direction at the center of the container, the cosmetic of a desired composition can be uniformly deposited on the applicator. Therefore, in the mode (B), it is possible to expect a more beautiful finish in a shorter time while maintaining the adjustment function.
