Description

  The present invention relates to a cosmetic including a container and a solid cosmetic stored in the container, and a method for manufacturing the cosmetic.

  Cosmetics having a form in which a solid cosmetic such as a foundation is housed in a container dish are generally filled with a cosmetic powder base material and then pressed with a pressing mold to mold the solid cosmetic material. It is manufactured by.

  In the molding of solid cosmetics by the so-called dry method, which uses dry raw material powder as the cosmetic powder base material, in order to obtain a solid cosmetic that is strong against impact and hardly loses its shape, While extracting, the raw material powder is pressed with a pressing die (Patent Document 1).

  In this case, a porous sheet is interposed between the receiving tray filled with the raw material powder and the pressing die, and at the same time as pressing the raw material powder with the pressing die, the air in the receiving tray is moved out of the receiving tray through the porous sheet. Escape is done. As such a porous sheet, a cloth capable of creating an air escape path between the stamping die and the raw material powder is used due to its thickness and texture. In this case, the regular texture of the cloth is transferred to the surface of the molded solid cosmetic material, and irregularities are formed. Further, paper is further interposed between the cloth and the cosmetic powder base material. Since the fibers of the paper are thin and the arrangement thereof is irregular, irregularities are not easily formed on the surface of the solid cosmetic, and the surface has a smooth shape as compared with the case where only the cloth is interposed.

  On the other hand, in the molding of solid cosmetics by a so-called wet method using a volatile oil agent slurry in which raw material powder is dispersed in a volatile oil agent as a cosmetic powder base material, the volatile oil agent is efficiently removed from the volatile oil agent slurry. In order to remove the volatile oil agent, the volatile oil agent slurry is pressed with a pressing die while extracting the volatile oil agent in the container (Patent Document 2).

  In this case, a porous sheet is interposed between the holding tray filled with the volatile oil slurry and the pressing die, and the raw material powder is pressed with the pressing die, and at the same time, the volatile oil agent is absorbed into the porous sheet and the pressing die. The volatile oil agent retained in the porous sheet is removed by suction through a suction hole provided in (Patent Document 3). As such a porous sheet, generally, paper or nonwoven fabric excellent in oil absorption is used. In this case, the surface of the solid cosmetic has a smooth shape with almost no unevenness.

This invention makes it a subject to provide the technique which forms the surface part of 2 or more from which the brightness differs on the surface of the solid cosmetics of a single composition. More specifically, the present invention provides a novel form of cosmetic in which two or more surface portions having different brightness are formed on the surface of a solid cosmetic composition having a single composition, and a method for efficiently producing such a cosmetic. Let it be an issue.
Also, some solid cosmetics have a tendency that the appearance color of the surface of the molded solid cosmetic and the coating color when the solid cosmetic is applied to the skin are separated by the optical characteristics of the constituent components. There are some which are difficult to imagine the application color when applied to the skin of various colors from the appearance color of the solid cosmetic.
Therefore, the present invention is close to the application color when the solid cosmetic is applied to a certain color skin by using a technique for forming two or more surface portions having different brightness on the surface of the solid cosmetic of a single composition. Another object of the present invention is to provide a cosmetic in which the color of the image is expressed on a part of the surface of the solid cosmetic, and a method for efficiently producing such a cosmetic.

Even when using the cosmetic powder base material of the same composition, the present inventors were molded by the type of the porous sheet interposed between the container tray and the pressing mold when molding the solid cosmetic. It has been found that the brightness of the surface of the solid cosmetic is different. And it discovered that the difference in brightness arises by the difference in the fine shape of the surface (surface pressed by the press die) of the shape | molded solid cosmetics.
Specifically, for example, when unevenness is present on the surface of the solid cosmetic, the brightness of the surface is smaller than when no unevenness is present, and the unevenness present on the surface of the solid cosmetic is reduced. It has been found that the lightness of the surface decreases as the size increases, and that the lightness of the surface changes if the irregularity regularity existing on the surface of the solid cosmetic changes.

Further, the present inventors, in the molding of solid cosmetics, as a porous sheet interposed between the container tray filled with the cosmetic powder base material and the pressing mold, the presence or absence of texture, regularity of the texture When a plurality of porous sheets having different surface shapes are stacked, the surface brightness of the molded solid cosmetic material is formed when each porous sheet is used alone. It was found that the brightness was different from any of the brightness values.
Based on these findings, the present inventors have invented the following novel cosmetics and manufacturing methods thereof.
That is, the present invention is as follows.

1st invention is cosmetics containing a storage dish and the solid cosmetics accommodated in this storage dish, Comprising: The surface of the said solid cosmetics differs in the surface shape from each other, At least 2 types of surface parts (Hereinafter, also referred to as “the cosmetics of the present invention”).
The at least two types of surface portions have different brightness depending on the difference in surface shape.

  The solid cosmetic may be molded using a so-called dry method or may be molded using a so-called wet method. The surface of the solid cosmetic refers to a surface formed by pressing with a pressing die, that is, a surface exposed from the opening of the storage tray after molding.

In the present invention, “the surface shapes are different from each other” of the solid cosmetic means that the surface shapes are different from each other to the extent that at least one of the lightness, hue, and saturation of the surface is different. It is possible to confirm that the surface shapes are different from each other under an optical microscope, for example.
Examples of different surface shapes include the presence or absence of unevenness, the difference in regularity of the unevenness, and the difference in size of the unevenness. The difference in irregularity regularity is a concept that includes both the presence or absence of irregularity irregularity and the difference in irregularity regularity type (appearance pattern of recesses and protrusions). It is. The difference in the size of the unevenness is a concept including both the difference in the depth of the concave portion and the height of the convex portion and the difference in the interval between the concave portion and the convex portion.

  Examples of the concept of the combination of the surface shapes of the first surface portion and the second surface portion include the following.

In the combinations of (1) to (3) in Table 1, the first surface portion has a lightness greater than that of the second surface portion. In the combination of (4) and (5), which surface portion has higher brightness is determined by the regularity of the unevenness of each surface portion (appearance pattern of recesses and protrusions) and the size of the unevenness.
The surface shape of each of the first surface portion and the second surface portion can be selected according to the purpose of use of the cosmetic. For example, the first surface portion has a surface shape that is close to the lightness of the applied color when applied to a certain color skin, and the second surface portion is applied color when applied to another color skin. The surface shape is such that the lightness is close to the lightness.
The difference in brightness value (ΔL value) between the first surface portion and the second surface portion is, for example, in the range of about 0.01 to 4.0. In addition, the brightness value of the first surface portion and the second surface portion is, for example, about −2.0 to +2.0, based on the brightness in a state where the solid cosmetic is applied to a standard color skin. It is in the range.

  The area ratio of the first surface portion and the second surface portion on the surface of the solid cosmetic is not particularly limited. For example, in the combinations of (1) to (5) in Table 1, the first surface portion is smaller than the second surface portion, for example, the first surface portion is about 10 to 40% of the entire surface. be able to.

  In the cosmetic of the present invention, the surface of the solid cosmetic material has a surface portion (third, fourth... Nth surface) having a surface shape different from any of the surface shapes of the first surface portion and the second surface portion. Part) may be further included, and the surface shape, area, etc. in that case are also arbitrary.

  Of the plurality of surface portions of the surface of the solid cosmetic, the surface portion, particularly the surface portion whose brightness is closer to the color of the coating color, preferably indicates that the appearance color of the surface portion is close to the coating color It has a display means. As one aspect thereof, each surface portion of the surface of the solid cosmetic can have display means for indicating that the appearance color is close to the applied color when applied to a predetermined skin color. By having such a display means, it becomes possible for a seller or a customer to imagine the application color of the solid cosmetic material more easily and appropriately from the appearance color of the solid cosmetic material. As a display means, the marking on the surface of solid cosmetics is mentioned, for example.

  The cosmetic of the present invention can be a foundation, eye shadow, cheek color, or the like. The cosmetic of the present invention is suitable for a refill cosmetic (so-called refill).

The cosmetic product of the present invention can be produced, for example, by pressing a cosmetic powder base material filled in a storage dish with a pressing die having at least two types of press surface portions having different surface shapes. .
In the present invention, the “cosmetic powder base material” is a raw material powder (which may optionally contain a small amount of an oil component) used for molding by a so-called dry method, and used for molding by a so-called wet method. It is a concept that includes both volatile oil slurry of raw material powder.
Further, the cosmetic of the present invention has, for example, a porous sheet interposed between the container tray filled with the cosmetic powder base material and the pressing mold, and air or volatile oil in the container dish is passed through the porous sheet. It can manufacture by pressing the said cosmetics powder base material with a pressing die, extracting.

In the present invention, “intervening” means a state in which any porous sheet covers at least half of the opening of the storage tray.
Examples of the porous sheet include cloth, paper, and non-woven fabric. The cloth should just be normally used for shaping | molding of solid cosmetics. For example, the weaving method of the fabric is plain weave, twill weave, or the like. Moreover, the magnitude | size (opening) of the weave of a cloth is 10-1500 mesh, for example, Preferably it is about 30-1200 mesh. The thickness of the cloth is about 0.01 to 0.5 mm, preferably 0.05 to 0.45 mm. Arbitrary fibers, such as nylon, acetate, cotton, and PET, can be used as the fibers constituting the cloth and the nonwoven fabric. Also, paper may be used as long as it is usually used for molding solid cosmetics. The amount of wrinkles is, for example, 10 to 40 g / m ² , and the thickness is, for example, 0.02 to 0.04 mm.

The way of interposing the porous sheet (the way of arrangement) is not particularly limited as long as the cosmetic of the present invention can be produced.
For example, by covering a part of the opening of the container tray with one kind of porous sheet, it corresponds to the first surface portion of the shape corresponding to the surface shape of the porous sheet and the surface shape of the pressing surface of the pressing die. It is possible to mold a solid cosmetic having the second surface portion of the shape on the surface.

  Moreover, the first surface portion having a shape corresponding to the surface shape of the first porous sheet is formed by covering different portions of the opening of the storage tray with two types of porous sheets having different surface shapes, respectively, The solid cosmetic which has the 2nd surface part of the shape corresponding to the shape of 2 porous sheets on the surface can be shape | molded.

Here, “the surface shapes are different from each other” of the porous sheet means that the surface shape is such that the above-mentioned “surface shapes are different from each other” state of the solid cosmetic can be realized by the pressing by the pressing die. It is different from each other.
Examples of different surface shapes include the presence or absence of weaves, the regularity of the weaves, the difference in the size of the weaves, the difference in the thickness of the threads There are differences in the surface shape of the fibers, differences in the thickness of the fibers, differences in the density of the fibers, and the like.
For example, fabrics have a texture, but paper and nonwovens do not have a texture. Further, the regularity of the fabric weave varies depending on the weaving method such as plain weave, twill weave and satin weave.

Further, the first porous sheet covering at least a part of the opening of the container tray is partially overlapped with the second porous sheet having a surface shape different from that of the first porous sheet. A first surface portion having a shape corresponding to the surface shape of the porous sheet or the second porous sheet, and a surface when the first porous sheet and the second porous sheet are overlapped and a predetermined pressure is applied. A solid cosmetic having a second surface portion having a shape corresponding to the shape can be obtained. According to this method, the discontinuity of the boundary between the first surface portion and the second surface portion can be reduced.
Hereafter, this manufacturing method (2nd invention) is demonstrated in detail.

  That is, the second invention is a process A in which a porous sheet is interposed between a container tray filled with a cosmetic powder base material and a pressing mold, and air or a volatile oil agent in the container dish through the porous sheet. A step B of pressing the cosmetic powder base material with a pressing die to mold a solid cosmetic, and in the step A, at least one of the openings of the container tray It is a method for producing a cosmetic, characterized in that a second porous sheet having a surface shape different from that of the first porous sheet is partially overlapped on the first porous sheet covering the part. .

The meaning of each term is as described above.
Examples of the concept of the combination of the first porous sheet and the second porous sheet include the following.

The first porous sheet preferably serves as a filter for removing air. Preferably, it is paper, a nonwoven fabric, or a cloth of 30 to 1200 mesh. Thereby, it is possible to prevent the powder in the cosmetic powder base material from entering the porous sheet as much as possible.
In the molding of a solid cosmetic by a wet method, the first porous sheet is preferably paper or non-woven fabric. Thereby, absorption to the porous sheet of the volatile oil agent in cosmetic powder base material can be accelerated | stimulated, and a volatile oil agent can be extracted efficiently.
When the first porous sheet is paper or non-woven fabric, the second porous sheet is preferably a cloth. Thereby, the surface part from which surface shape mutually differs can be easily formed in the surface of solid cosmetics. Moreover, in the molding of the solid cosmetic by the dry method, by using a cloth as the second porous sheet, an air escape path is secured between the first porous sheet and the pressing die, and the solid is efficiently solidified. It can ventilate cosmetics.

  The method of stacking the first porous sheet and the second porous sheet can be arbitrarily selected. For example, the area in which the first porous sheet covers the opening of the storage tray may be made larger than the area in which the second porous sheet covers the opening of the storage tray (see FIG. 1A), and vice versa. (See FIG. 1B). In the form of FIG. 1 (a) and FIG. 1 (b), the opening of the receiving tray is completely covered with any porous sheet. However, as shown in FIG. It is also possible to adopt a form in which the opening is not completely covered with any porous sheet.

  The area ratio of the first porous sheet and the second porous sheet that covers the receiving tray is not particularly limited. For example, in the combinations of (1) to (3) in Table 2, the area of the portion covering the receiving tray of the first porous sheet is about 80 to 100% with respect to the area of the entire receiving tray, the second porous The area of the portion covering the storage tray of the adhesive sheet can be about 50 to 80% with respect to the area of the entire storage tray.

The first porous sheet preferably covers the entire opening of the storage tray (see FIG. 1A). Thus, the second porous end of the sheet is transferred decreases the depth of the linear groove formed, it is possible to smoothly form the boundary of the surface portion of the surface of the solid cosmetic.

  Further, when the solid cosmetic is molded using a dry method, when using paper or nonwoven fabric as the first porous sheet and using cloth as the second porous sheet, the second porous sheet is Preferably, it covers an area larger than half of the opening of the storage tray, more preferably 60% or more, and even more preferably 75% or more. As a result, a sufficient air escape path can be secured and air can be extracted efficiently.

  In the manufacturing method of the present invention, a porous sheet having a surface shape different from any of the surface shapes of the first porous sheet and the second porous sheet (third, fourth,. .. nth porous sheet) may be further overlapped and the surface shape in that case, the way of interposition, etc. can be arbitrarily set.

  The production method of the present invention can be carried out using a hand-type pressing device or an automatic pressing device. As the hand-type pressing device, one that is usually used for molding a solid cosmetic can be used.

As an automatic press device, for example, a supply hopper that supplies a cosmetic powder base material to a storage tray, a base on which a storage tray supplied with the cosmetic powder base material by the supply hopper, A first transfer means for transferring the first porous sheet to a position covering at least a part of the opening of the storage tray; and at least one of the openings of the storage tray above the first porous sheet. A second transfer means for transferring the second porous sheet to a position that covers the portion and partially overlaps the first porous sheet, the first porous sheet, and the second porous sheet In the state which overlapped, the apparatus provided with the pressing die which presses the cosmetics powder base material in the said accommodation tray from the top can be used.
Product productivity can be raised by using such an apparatus.

The cosmetic of the present invention makes it possible for a seller or a customer to recognize the difference between the appearance color and the application color of the solid cosmetic. In addition, the cosmetic of the present invention makes it possible to present a surface portion having a lightness closer to the applied color according to the color of the applied skin, and to the seller or customer with the appearance color of the solid cosmetic. It makes it possible to recognize colors more appropriately.
Moreover, the manufacturing method of the cosmetics of this invention makes it possible to produce the cosmetics of this invention efficiently.

The surface of the solid cosmetic 3 has a first surface portion 41 and a second surface portion 42. The area of the first surface portion 41 occupies about 15% of the area of the entire surface.
The first surface portion 41 does not have unevenness within a range that can be visually recognized by the naked eye, and the second surface portion 42 has continuous lattice-like unevenness in which the fabric texture is transferred.
In the first surface portion 41 and the second surface portion 42, the first surface portion has a higher lightness, and the lightness difference (ΔL value) is about 0.4 to 0.5.

The refillable cosmetic (foundation refill) 1 shown in FIG. 2B differs from the cosmetic shown in FIG. 2A only in the surface shape of each surface portion. The first surface portion 43 has grid-like continuous irregularities such that the fabric texture is transferred, and the second surface portion 44 has a grid-like shape where the fabric texture is transferred. It is a continuous unevenness, and has an unevenness larger than the unevenness formed in the first surface portion 43.
In the first surface portion 43 and the second surface portion 44, the first surface portion has higher lightness, and the lightness difference (ΔL value) is about 0.6 to 0.7.

Hereinafter, an embodiment of the manufacturing method of the present invention using an automatic press apparatus will be described with reference to FIGS. 3 and 4. In this embodiment, the cosmetic powder base material Q is a raw material powder (main component: talc, natural mica, synthetic gold mica, synthetic phlogopite, titanium oxide, sericite) used in a so-called wet method. is there.
As shown in FIG. 3, the automatic press device 5 includes a base 6 on which the receiving tray 2 for filling the cosmetic powder base material Q is placed, and the cosmetic powder base material Q in the receiving tray 2. A supply hopper 7 is provided.
Further, the apparatus transfers a roll paper (first porous sheet) M having a width of about 70 to 100 cm to a position that covers at least a part of the opening of the storage tray 2. Take-up roller 82 and a pair of guide rollers 83, 83 (first transfer means). The first feed roller 81 feeds the roll paper M, and the first take-up roller 82 winds up the roll paper M corresponding to the length fed by the first feed roller. The pair of first guide rollers 83, 83 grips the roll paper M above the base 6 and determines the position of the roll paper M with respect to the storage tray 2.
The apparatus also has a roll cloth (second porous sheet, plain woven cloth made of acetate) N at a position that is above the roll paper M and partially overlaps the roll paper M. A second feed roller 91, a second take-up roller 92, and a pair of guide rollers 93, 93 are provided (second transfer means). The second feed roller 91 feeds the roll cloth N, and the first take-up roller 92 winds the roll cloth N for the length fed by the second feed roller. The pair of second guide rollers 93, 93 grips the roll cloth N above the base 6 and determines the position of the roll cloth N with respect to the storage tray 2 and the roll paper M.
In addition, the apparatus includes a pressing die 10 that presses the cosmetic powder base material in the storage tray from above in a state where the roll paper M and the roll cloth N partially overlap.

  The second guide rollers 93, 93 are supported by a push die holder 11 that holds the push die 10, and are configured to be rotatable around a vertical axis passing through the center of the push die 10. The guide roller is configured to be slidable in the axial direction of the guide roller.

  Furthermore, the automatic pressing device 5 has a conveyor device 12 that moves the base 6 in a direction from the lower side of the supply hopper 7 toward the lower side of the pressing die 10. The conveyor device 12 conveys the receiving tray 2 set on the base 6 from below the supply hopper 7 to below the pressing die 10 (in the direction of arrow A in FIG. 3).

  FIG. 4A to FIG. 4D are state diagrams of each process of the present embodiment. First, the storage tray 2 is set on the base 6, and the storage tray 2 is conveyed to the lower side of the supply hopper 7 by the conveyor device 12. Then, the cosmetic powder base material Q is supplied into the container tray 2 by the supply hopper 7, and the interior of the container tray 2 is filled with the cosmetic powder base material Q (FIG. 4A).

The container tray 2 filled with the cosmetic powder base material Q is further conveyed by the conveyor device 12 to a predetermined position below the roll paper M and the roll cloth N (FIG. 4B).
At this point, the roll paper M and the roll cloth N are arranged so as to partially overlap above the opening of the storage tray by the first guide rollers 83 and 83 and the second guide rollers 93 and 93. Yes.
For example, in one form, the roll paper M is fixed by the first guide rollers 83 and 83 so that the long side thereof is parallel to the transfer direction of the base 6, and the long side of the roll cloth N is the base. The second guide rollers 93 and 93 are fixed so as to have an angle of about 30 to 45 ° C. with respect to the transfer direction 6. Then, the rectangular storage tray 2 is conveyed so that one side thereof is parallel to the transfer direction of the base 6. FIG. 5A shows the positional relationship between the roll paper M, the roll cloth N, and the storage tray 2 in this form.
In another form, the long sides of the roll paper M and the roll cloth N are parallel to the transfer direction of the base 6, but the first guide rollers 83, 83 and the second guide so as to partially overlap each other. The rectangular storage tray 2 fixed by the guide rollers 93, 93 is conveyed so that one side thereof is at an angle of about 30 to 45 ° C. with respect to the transfer direction of the base 6. FIG. 5B shows the positional relationship between the roll paper M, the roll cloth N, and the storage tray 2 in this form.

Subsequently, the cosmetic powder base material Q is pressed with the pressing die 10 (FIG. 4C). The pressing may be usually performed at a pressure in a range used for molding a solid cosmetic, for example, a molding cylinder diameter of 60φ to 80φ, a range of about 15 to 50 kg / cm ² , and a total pressure of 400 kg to 2500 kg. It is a range.

Subsequently, the pressing die 10 is separated from the cosmetic powder base material, and the cosmetic is completed (FIG. 4D). The finished cosmetic has the form shown in FIG. In FIG. 2A, the first surface portion 41 is a portion formed by only the roll paper M interposed between the storage tray 2 and the pressing die 10, and the second surface portion 42 is This is a portion formed by interposing the roll cloth N on the roll paper M between the storage tray 2 and the pressing die 10. The first surface portion 41 does not have unevenness that is visible to the naked eye, and the second surface portion 42 has unevenness corresponding to the surface shape of the roll cloth N. That is, the texture of the roll cloth N is transferred from the top of the roll paper M to the second surface portion 42.
As described above, in the first surface portion 41 and the second surface portion 42, the first surface portion has higher brightness.
The portions of the roll paper M and the roll cloth N that are in contact with the cosmetic powder base material and the pressing die are wound by the first winding roller 82 and the second winding roller 92 as necessary. At the same time, new roll paper M and roll cloth N are fed by the first feeding roller 81 and the second feeding roller 82 to prepare for the next molding of the solid cosmetic.

Below, it was investigated how the brightness of the surface of the molded solid cosmetic material changed when the porous sheets interposed between the container and the pressing mold were stacked in various combinations.
Solid cosmetics were molded by a hand-type pressing device by a so-called dry method using a foundation raw material powder mainly composed of talc and natural mica. Subsequently, the brightness of a specific surface portion of the surface of the solid cosmetic was measured with a color difference meter. Table 3, the brightness of the porous sheet, and the surface portion was used (L value), indicating the difference from the control ([Delta] L value).

In the test numbers 2 to 4 in which a nylon cloth is placed on the cosmetic base material and an acetate cloth is placed on the nylon cloth, the molded solid cosmetic is compared with the control in which only the acetate cloth is interposed. The brightness of the surface of the surface became smaller. Moreover, it turned out that the lightness of the surface of the shape | molded solid cosmetics becomes large, so that the texture of the cloth arrange | positioned at the makeup base material side becomes large from the comparison of the result of test numbers 2-4. When the surfaces of these solid cosmetics were observed, lattice-shaped fine irregularities were formed on the control. Further, in Test Nos. 2 and 3, wide and deep lattice-like irregularities were formed as compared with the control. In these examples, the irregularity regularity was different from that of the control. Comparing the results of test numbers 2 and 3, test number 2 had wider and deeper irregularities. In test number 4, fine irregularities in a lattice shape having the same width and depth as the control were formed, but the regularity thereof was different from the irregularities of the control.
From this, the greater the width and depth of the unevenness present on the surface of the solid cosmetic, the smaller the brightness of the surface, and if the irregularity regularity present on the surface of the solid cosmetic changes, the brightness of the surface Was found to change. In addition, the width and depth of the unevenness of the solid cosmetic may be increased by increasing the size of the texture of the porous sheet that contacts the cosmetic base material when pressed by the pressing die, or by increasing the thickness of the thread. It was found that it can be wide and deep.

In Test Nos. 5 and 6 in which paper is placed on the cosmetic base material and an acetate cloth is interposed between them, the surface of the molded solid cosmetic is compared with the control in which only the acetate cloth is interposed. The brightness has increased.
Also, from comparison of the results of test numbers 5 and 6, it was found that the thicker the paper, the higher the brightness. A similar tendency can be seen from comparing the results of test numbers 7 and 8, test numbers 10 and 11, and test numbers 13 and 14. This is probably because the thicker paper is, the more difficult it is to transfer the texture of the cloth to be stacked on the surface of the solid cosmetic by pressing with the pressing die. When the surfaces of these solid cosmetics were observed, in the example of test number 5, fine lattice-like irregularities were formed, but the depth was small. In the example of test number 6, the same unevenness was formed, but its depth was smaller than that of the example of test number 5.
From this, in addition to the above knowledge, it has been found that arranging the paper on the cosmetic base material side acts in the direction of increasing the brightness, and that the action becomes more prominent as the paper is thicker.

  In Test Nos. 9 and 12, in which a nylon cloth (ultra thin) is placed on the cosmetic base material and a nylon cloth (thin or thick) is interposed between them, thin paper is used instead of the nylon cloth (ultra thin). The lightness was smaller than that of test number 8 or test number 11. This is because nylon cloth (ultra-thin) works in the direction of reducing lightness compared to paper, and because of its thinness and softness, it is easy to transfer the texture of the overlapping cloth onto the solid cosmetic surface. It is thought that. Nylon cloth (ultra-thin) is easy to transfer the texture of the cloth to be layered. When nylon cloth (thickness) is layered on nylon cloth (ultra-thin) of test number 9, nylon cloth (test number 12) This was also supported by the formation of wide and deep irregularities on the surface of the solid cosmetic compared to the case of superimposing nylon cloth (thin) on ultrathin.

  From this, when paying attention to the relationship between the brightness of the surface of the first porous sheet or the second porous sheet and the solid cosmetic material to be molded, the case of using paper or non-woven fabric is more than the case of using cloth. In the case of paper or non-woven fabric, the brightness becomes higher as the thick paper is used. In the case of the cloth, the lightness becomes higher as the thin cloth is used, and the thinner the first porous sheet is, It has been found that the influence of the second porous sheet on the brightness is significant.

From the above results, in the molding of solid cosmetics, solid cosmetics that are molded by interposing a porous sheet having a different surface shape between the container tray filled with the cosmetic base material and the pressing mold are overlapped. It was found that the brightness of the surface of the material can be adjusted.
And in the molding of solid cosmetics, a solid sheet of a single composition is formed by interposing a porous sheet with different surface shapes partially overlapping between the container tray filled with the cosmetic base material and the pressing mold. It was found that two or more surface portions having different brightness values can be formed on the surface of the cosmetic.

  Moreover, when the foundation used in the above test was applied to the inside of the paneler's wrist and the brightness was measured, the brightness was almost the same as the brightness of the surface of the solid cosmetic of test number 6. From this, it was found that the solid color of Test No. 6 most accurately represents the applied color when this foundation was applied to the skin of the same color as the color inside the wrist of the paneler. . Therefore, when the first surface portion of the surface of the solid cosmetic is molded so as to have the surface shape of test number 6, the appearance color of the first surface portion is applied to the skin of the color.
