Description

[Technical field]

[0001] The present invention relates to a carrier for impregnating with a cosmetic preparation. More specifically, the present invention relates to a carrier for impregnating with a cosmetic preparation used to hold a cosmetic preparation, a cosmetic-impregnated body containing a cosmetic preparation in the carrier for impregnating with a cosmetic preparation, and a cosmetic product having the cosmetic-impregnated body. The carrier for impregnating with a cosmetic preparation of the present invention can be suitably used for, for example, a cosmetic-impregnated body impregnated with a cosmetic preparation such as foundation, as well as a puff used for applying a cosmetic preparation to the skin, etc. [Background technology]

[0002] Liquid cosmetics such as foundation are stored in a cosmetic container such as a compact. The cosmetic container has a container body and a lid, and a cosmetic-impregnated body for holding the liquid cosmetic is stored in the container body. Soft sponges such as polyethylene foam, polyurethane foam, and rubber foam have traditionally been used as the cosmetic-impregnated body, but recently polyether-based urethane foam has been proposed as a cosmetic-holding carrier that has stable cosmetic retention properties (see, for example, Patent Document 1).

[0003] However, although the liquid cosmetic material present on the surface of the polyether polyurethane foam can be easily attached to a puff or the like, the liquid cosmetic material is trapped in the bubbles due to the bubble structure, and cannot be easily removed to the outside with a puff or the like. This has the drawback that a large amount of unused liquid cosmetic material remains inside the polyether polyurethane foam. In addition, since polyurethane foam is a foam having urethane bonds rather than fibers, it has poor light resistance and is prone to yellowing due to sunlight, etc., which may lead to a decrease in commercial value. Furthermore, it may be difficult to fill polyurethane foam with liquid cosmetic material depending on the viscosity of the liquid cosmetic material.

[0004] In recent years, for example, there has been a demand for the development of a carrier for impregnating with a cosmetic material that allows a large amount of cosmetic material to be easily loaded into the carrier and that allows the cosmetic material to be continuously and almost uniformly extracted from the cosmetic-impregnated body in which the cosmetic material has been loaded.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] As described above, the carrier for being impregnated with a cosmetic preparation of the present invention is a carrier for being impregnated with a cosmetic preparation used for holding a cosmetic preparation, and is characterized by having through holes extending from the front surface to the back surface of the carrier for being impregnated with a cosmetic preparation.

[0013] The carrier for impregnation with a cosmetic preparation means a carrier used for impregnation with a cosmetic preparation. The cosmetic-impregnated body of the present invention is characterized in that the carrier for impregnation with a cosmetic preparation contains a cosmetic preparation. The cosmetic-impregnated body means an impregnated body in which the carrier for impregnation with a cosmetic preparation is impregnated with a cosmetic preparation.

[0014] The carrier for impregnation with a cosmetic material of the present invention can be used as a carrier for impregnation with a high-viscosity cosmetic material or a carrier for impregnation with a low-viscosity cosmetic material. The carrier for impregnation with a high-viscosity cosmetic material means a carrier for impregnation with a cosmetic material used to hold a high-viscosity cosmetic material. The carrier for impregnation with a low-viscosity cosmetic material means a carrier for impregnation with a cosmetic material used to hold a low-viscosity cosmetic material. In the present invention, the carrier for impregnation with a cosmetic material is a concept that includes both a carrier for impregnation with a high-viscosity cosmetic material and a carrier for impregnation with a low-viscosity cosmetic material.

[0015] The cosmetic preparation generally has a viscosity at 25°C of preferably 500 to 100,000 mPa·s, and more preferably 500 to 80,000 mPa·s.

[0016] In the present invention, a high-viscosity cosmetic means a cosmetic having a viscosity of 20000 mPa·s or more at 25°C. From the viewpoint of easily filling a large amount of the high-viscosity cosmetic into a carrier for impregnation with the high-viscosity cosmetic and effectively realizing the ability to continuously and substantially uniformly remove the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated body, the lower limit of the viscosity of the high-viscosity cosmetic is preferably 20000 mPa·s or more, more preferably 30000 mPa·s or more, even more preferably 35000 mPa·s or more, even more preferably 40000 mPa·s or more, and even more preferably 50000 mPa·s or more. From the viewpoint of easily filling a large amount of the high-viscosity cosmetic into a carrier for impregnation with the high-viscosity cosmetic and effectively realizing the ability to continuously and substantially uniformly remove the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated body, the upper limit of the viscosity of the high-viscosity cosmetic is preferably 100000 mPa·s or less, more preferably 80000 mPa·s or less. Therefore, the viscosity of a high-viscosity cosmetic preparation at 25°C is preferably 20,000 to 100,000 mPa·s, more preferably 30,000 to 80,000 mPa·s, even more preferably 35,000 to 80,000 mPa·s, even more preferably 40,000 to 80,000 mPa·s, and even more preferably 50,000 to 80,000 mPa·s.

[0017] In the present invention, a low-viscosity cosmetic refers to a cosmetic having a viscosity of less than 20,000 mPa·s at 25° C., among the above-mentioned cosmetics. From the viewpoint of enabling the low-viscosity cosmetic to be easily and large-quantity loaded into a carrier for impregnating the low-viscosity cosmetic, and effectively enabling the low-viscosity cosmetic to be continuously and almost uniformly extracted from the low-viscosity cosmetic-impregnated body, the lower limit of the viscosity of the low-viscosity cosmetic is preferably 500 mPa·s or more, more preferably 600 mPa·s or more, even more preferably 700 mPa·s or more, even more preferably 800 mPa·s or more, and even more preferably 900 mPa·s or more. The upper limit of the viscosity of the low-viscosity cosmetic is preferably less than 20,000 mPa·s, more preferably 19,900 mPa·s or less, even more preferably 19,000 mPa·s or less, still more preferably 18,000 mPa·s or less, and even more preferably 17,000 mPa·s or less, from the viewpoints of easily loading a large amount of the low-viscosity cosmetic into a carrier for impregnation with the low-viscosity cosmetic and continuously and uniformly extracting the low-viscosity cosmetic from the low-viscosity cosmetic-impregnated body. Therefore, the viscosity of the low-viscosity cosmetic at 25°C is preferably 500 to less than 20,000 mPa·s, more preferably 600 to 1,990 mPa·s, even more preferably 700 to 19,000 mPa·s, even more preferably 800 to 18,000 mPa·s, and even more preferably 900 to 17,000 mPa·s.

[0018] The viscosity of the high-viscosity cosmetic composition and the low-viscosity cosmetic composition are values ​​measured at a temperature of 25°C using a BM type viscometer.

[0019] Examples of the carrier for impregnating with a cosmetic preparation include composite fibers, rubber latex elastic foams, polyurethane foams, etc., but the present invention is not limited to these examples. Among these, composite fibers are preferred from the viewpoints of easily loading a large amount of the cosmetic preparation into the carrier for impregnating with a cosmetic preparation and continuously and almost uniformly extracting the cosmetic preparation from the cosmetic preparation-impregnated body.

[0020] The carrier for impregnating with a cosmetic preparation of the present invention preferably has a three-dimensional structure made of composite fibers, from the viewpoints of being able to easily fill a large amount of cosmetic preparation and being able to continuously and substantially uniformly extract the cosmetic preparation from the cosmetic preparation-impregnated body in which the cosmetic preparation has been filled.

[0037] From the viewpoint of firmly integrating the contact portions between the constituent fibers with the resin X, it is possible to use, as the thermoplastic elastomer, a polyether polyester having polybutylene terephthalate as a hard segment and polyoxybutylene glycol as a soft segment.

[0038] In the hard segment, a part of the acid component used as a raw material for polybutylene terephthalate may be substituted with an acid such as a dicarboxylic acid or an oxycarboxylic acid other than terephthalic acid, as long as the object of the present invention is not hindered. Also, a part of butylene glycol used as a raw material for polyoxybutylene glycol may be substituted with another polyhydric alcohol as long as the object of the present invention is not hindered.

[0040] Examples of resin Y include thermoplastic polyester, but the present invention is not limited to these examples.

[0041] Examples of thermoplastic polyesters include polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, polyhexamethylene terephthalate, polytetramethylene terephthalate, poly1,4-dimethylcyclohexane terephthalate, and polyhydrolactone, but the present invention is not limited to these examples. These thermoplastic polyesters may be used alone or in combination of two or more. Among these thermoplastic polyesters, polyethylene terephthalate, polytrimethylene terephthalate, polybutylene terephthalate, and polyhexamethylene terephthalate are preferred because of their excellent light resistance.

[0042] From the viewpoint of preventing the composite fiber from becoming sagging, the melting temperature of resin Y is preferably at least 20° C. higher, and more preferably at least 30° C. higher, than the melting temperature of resin X. From the viewpoint of preventing the composite fiber from becoming sagging and firmly integrating the contact parts between the constituent fibers with resin X, the melting temperature of resin Y is preferably 150 to 270° C., and more preferably 160 to 270° C.

[0043] From the viewpoints of improving the light resistance of the composite fiber, preventing sagging of the composite fiber, and firmly integrating the contact areas between the constituent fibers with resin X, it is preferable that resin X is a polyester or a polyester-based elastomer and resin Y is a thermoplastic polyester.

[0044] From the viewpoint of preventing the composite fibers from becoming worn out and firmly integrating the contact areas between the constituent fibers with resin X, it is preferable that 30 to 70% of the surface area of ​​the composite fibers is composed of resin X and 70 to 30% of the surface area of ​​the composite fibers is composed of resin Y.

[0045] The composite fiber contains resin X and resin Y having a higher melting temperature than resin X, but may contain resins other than resin X and resin Y as long as the object of the present invention is not impaired.

[0046] The composite fiber contains resin X and resin Y. When the composite fiber is a core-sheath type composite fiber or a side-by-side type composite fiber, two types of resins, resin X and resin Y, are usually used. When the composite fiber is an islands-in-the-sea type composite fiber, two to four types of resins including resin X and resin Y, preferably two or three types of resins, and more preferably two types of resins, resin X and resin Y, are usually used.

[0047] In the case of core-sheath type composite fibers, from the viewpoint of firmly integrating the contact areas between the constituent fibers with resin X, it is preferable to use resin Y for the core component and resin X for the sheath component.

[0048] In the sheath-core composite fiber, it is preferable that the core component is not exposed on the surface of the composite fiber. It is more preferable that the center of the core component in the fiber diameter direction coincides with the center of the sheath component in the fiber diameter direction. The sheath-core composite fiber may have a concentric core-sheath structure, or an eccentric core-sheath structure. Composite fibers having an eccentric core-sheath structure are suitable for applications requiring crimping because they crimp when heated.

[0049] Examples of the cross-sectional shape of the core-sheath type composite fiber include a circle, an ellipse, an oval, a triangle, a rectangle, and other polygonal shapes, but the present invention is not limited to these examples. Among these shapes, a circle is preferable.

[0050] The volume ratio of the core component to the sheath component of the core-sheath type composite fiber (core component:sheath component) is preferably 30:70 to 70:30 from the viewpoints of improving the single fiber strength and firmly integrating the contact parts between the constituent fibers with the resin X.

[0051] When the composite fiber is a sheath-core composite fiber, the composite fiber can be produced, for example, by heating and melting resin Y and resin X, which respectively constitute the core component and the sheath component, introducing them into a composite spinning device for producing a sheath-core composite fiber, and extruding and spinning them from a sheath-core composite nozzle. When heating and melting resin X and resin Y, for example, a single-screw extruder, a twin-screw extruder, a kneader, or the like can be used. In addition, as the composite nozzle, for example, a composite nozzle in which the nozzle holes are arranged in a staggered or annular arrangement can be used.

[0052] Next, the spun core-sheath type composite fiber can be cooled and solidified, for example, by blowing cold air onto the core-sheath type composite fiber.

[0053] From the viewpoint of obtaining a carrier for impregnating with a cosmetic preparation that can efficiently remove the cosmetic preparation from the cosmetic preparation-impregnated body and has excellent mechanical strength, the fineness of the composite fiber is preferably 0.5 to 15 denier, and more preferably 1 to 10 denier. In the present invention, the fineness of the fiber means the mass (g) of the fiber (filament) per 9000 m of fiber length.

[0054] The fiber length of the composite fiber is preferably about 20 to 150 mm from the viewpoint of obtaining a carrier for being impregnated with a cosmetic material, which allows the cosmetic material to be efficiently removed from the cosmetic material-impregnated body and has excellent mechanical strength.

[0055] From the viewpoint of preserving the cosmetics used in the cosmetic-impregnated carrier, the composite fiber may be subjected to, for example, antibacterial or antimicrobial treatment, if necessary. Various methods can be used for such treatment, and the present invention is not limited to such methods.

[0056] The carrier for being impregnated with a cosmetic preparation may be composed of only composite fibers, or may be composed of composite fibers and fibers other than the composite fibers.

[0057] Examples of other fibers include natural fibers such as cotton, hemp, and silk, regenerated fibers such as rayon, and synthetic fibers, but the present invention is not limited to these examples. Among these other fibers, synthetic fibers are preferred from the viewpoint of obtaining a carrier for impregnation with a cosmetic material, which can efficiently remove the cosmetic material from the cosmetic material-impregnated body and has excellent mechanical strength.

[0058] Examples of synthetic fibers include polyester fibers such as polyethylene terephthalate fibers, polybutylene terephthalate fibers, and polytrimethylene terephthalate fibers, polyvinyl chloride fibers, polyvinylidene chloride fibers, polypropylene fibers, polyvinyl alcohol fibers, polyamide fibers such as nylon 6, polyimide fibers, polyamideimide fibers, and cellulose acetate fibers, but the present invention is not limited to these examples. These fibers may be used alone or in combination of two or more types. Among these synthetic fibers, polyester fibers and polyamide fibers are preferred, and polyester fibers are more preferred, from the viewpoint of obtaining a carrier for impregnating with a cosmetic material that can efficiently remove the cosmetic material from the cosmetic material-impregnated body and has excellent light resistance.

[0059] From the viewpoint of preserving the cosmetics used in the cosmetic-impregnated carrier, the synthetic fibers may be subjected to, for example, antibacterial or antimicrobial treatment, if necessary. Various methods can be used for such treatment, and the present invention is not limited to such methods.

[0060] From the viewpoint of preventing the composite fiber from becoming sagging, the melting temperature of the synthetic fiber is preferably at least 20° C. higher, and more preferably at least 30° C. higher, than the melting temperature of the resin X. From the viewpoint of preventing the composite fiber from becoming sagging and efficiently heat-fusing the composite fiber and the synthetic fiber at their intersections, the melting temperature of the synthetic fiber is preferably 150 to 270° C., and more preferably 160 to 270° C.

[0061] The fineness of the synthetic fibers is preferably 0.5 to 15 denier, and more preferably 1 to 10 denier, from the viewpoint of obtaining a carrier for being impregnated with a cosmetic material that can efficiently remove the cosmetic material from the cosmetic material-impregnated body.

[0062] The fiber length of the synthetic fiber is preferably about 20 to 150 mm from the viewpoint of obtaining a carrier for being impregnated with a cosmetic material, which allows the cosmetic material to be efficiently removed from the cosmetic material-impregnated body and has excellent mechanical strength.

[0063] In the present invention, from the viewpoint of obtaining a support for impregnation with a cosmetic material that can efficiently remove the cosmetic material from the cosmetic material-impregnated body and has excellent light resistance, it is preferable to use a combination of the composite fiber and a synthetic fiber as the other fiber, it is more preferable to use a combination of the composite fiber and a polyester fiber or a polyamide fiber as the synthetic fiber, and it is even more preferable to use a combination of the composite fiber and a polyester fiber.

[0064] The mass ratio of the composite fiber to the synthetic fiber (composite fiber / synthetic fiber) is preferably 10 / 90 to 100 / 0, and more preferably 30 / 70 to 80 / 20, from the viewpoint of obtaining a carrier for impregnating with a cosmetic material that can efficiently heat-fuse the composite fiber and the synthetic fiber at their intersections and efficiently remove the cosmetic material from the cosmetic material-impregnated body.

[0065] The carrier for impregnation with a cosmetic preparation can be produced, for example, as follows. Although an example in which composite fibers and synthetic fibers are used in combination is shown below, composite fibers alone may be used, or composite fibers may be used in combination with fibers other than synthetic fibers.

[0066] First, the composite fiber and the synthetic fiber are each defibrated, weighed out to have a predetermined ratio, and mixed to have a uniform composition to form a web.

[0067] It is preferable that the thickness of the formed web is appropriately adjusted depending on the size of the carrier to be impregnated with a cosmetic preparation in which the web is to be used.

[0068] Next, for example, the web is sandwiched between two flat plates, and if necessary, the web is pressed to a predetermined thickness, and in this state, the web is heated at a temperature equal to or higher than the melting temperature of the resin X constituting the composite fiber contained in the web and lower than the melting temperature of the resin Y and synthetic fiber constituting the composite fiber to melt the resin X, and the contact portions of the fibers containing the composite fiber and the synthetic fiber are fused and integrated by the molten resin X, thereby obtaining a web sheet. At this time, if necessary, the web sheet obtained as described above is placed in a mold so as to have a predetermined density, and the web sheet is heated in the same manner as described above to melt the resin X, thereby fusing the intersections of the constituent fibers with the molten resin X, and a fused portion in the shape of a lump (amoeba) made of resin X can be formed at the intersections.

[0069] In addition, when a web sheet is produced by mixing composite fibers and synthetic fibers and laminating the composite fibers and the synthetic fibers so that the fibers are both parallel to the fiber length direction, when the web sheet is stretched in the thickness direction, stripes appear indicating that the composite fibers and the synthetic fibers are both parallel to the fiber length direction. These stripes are an indicator that the web sheet was produced by the above-mentioned method.

[0070] Next, the web sheet obtained above is cut into a desired size and shape, thereby obtaining a carrier for being impregnated with a cosmetic preparation.

[0071] The size and shape of the carrier to be impregnated with a cosmetic preparation vary depending on the application of the carrier, and therefore cannot be determined in general terms. It is therefore preferable to adjust them appropriately depending on the application of the carrier to be impregnated with a cosmetic preparation.

[0072] An example of the carrier for impregnating with a cosmetic preparation is a cylindrical carrier for impregnating with a cosmetic preparation having a planar shape of a circle with a diameter of about 3 to 15 cm and a thickness of about 0.5 to 5 cm. The carrier for impregnating with a cosmetic preparation can be suitably used as a carrier for impregnating with a cosmetic preparation for holding a cosmetic preparation such as foundation.

[0073] The density of the carrier to be impregnated with a cosmetic preparation cannot be determined in general because it varies depending on the application of the carrier to be impregnated with a cosmetic preparation, but is preferably 6 to 50 kg / m 3 , more preferably 6 to 30 kg / m 3 It is.

[0074] In order to prevent the carrier from becoming worn out during use, it is preferable that a web sheet in which the composite fibers and synthetic fibers are laminated so that their fiber length directions are parallel to each other and that the fibers are aligned in the fiber length direction along the thickness direction of the carrier for impregnating with the cosmetic preparation.

[0075] In the carrier for impregnating a cosmetic preparation, when the composite fibers contain resin X and resin Y having a melting temperature higher than that of resin X, and the contact areas between the constituent fibers are integrated by resin X of the composite fibers, voids exist between the fibers and the voids are fixed. Therefore, in contrast to rubber latex elastic foam and polyurethane foam, the cosmetic preparation can be efficiently removed from the cosmetic preparation-impregnated body through the voids between the fibers, thereby reducing the residual rate of the cosmetic preparation after use.

[0076] Furthermore, when the constituent fibers constituting the carrier for impregnation with a cosmetic preparation include composite fibers in which resin X is polyester or a polyester-based elastomer and resin Y is a thermoplastic polyester, and polyester monofilaments are used as fibers other than the composite fibers, light resistance is effectively exhibited.

[0077] In addition, in the case of a cosmetic-impregnated carrier, when the composite fiber contains resin X and resin Y having a melting temperature higher than that of resin X and the contact parts between the constituent fibers are integrated by resin X of the composite fiber, the carrier has excellent retention (non-adsorption) of the ultraviolet absorbent contained in the cosmetic, and further has excellent durability since it is less likely to wear down due to repeated use.

[0078] From the viewpoint of preventing a large amount of cosmetic from being removed at the beginning of use, it is preferable that the carrier for being impregnated with a cosmetic preparation has a dense fibrous surface layer and a sparse fibrous base material, and that the dense fibrous surface layer and the sparse fibrous base material are integrated together.

[0079] A carrier for impregnation with a cosmetic preparation, in which a dense fibrous surface layer and a sparse fibrous substrate are integrated, can be obtained, for example, by pressing a web sheet, heating the pressed surface in a compressed state, forming a dense fibrous layer on the surface of the web sheet, and then cooling and depressurizing. The density of the dense fibrous surface layer can be controlled by appropriately adjusting the heating temperature, pressing time, and pressing force when pressing the web sheet. Here, integration of the dense fibrous surface layer with the sparse fibrous substrate means directly forming the dense fibrous surface layer on the surface of the sparse fibrous substrate.

[0080] The heating temperature when the web sheet is pressed and the pressed surface is heated in a compressed state is preferably 150° C. or higher from the viewpoint of forming a dense surface structure. The heating time and pressing force can be appropriately adjusted so that the web sheet has a predetermined thickness. When the web sheet is pressed and the pressed surface is heated in a compressed state, for example, by heating the web sheet for several minutes at a temperature equal to or higher than the melting temperature of the resin constituting the web sheet, a dense fibrous surface layer can be formed.

[0081] The thickness of the dense fibrous surface layer is preferably about 50 μm to 5 mm from the viewpoint of preventing a large amount of the cosmetic material taken into the interior of the cosmetic-impregnated body from being removed at once at the beginning of use. The thickness of the sparse fibrous base material is preferably about 500 μm to 10 cm, more preferably 5 to 20 mm, from the viewpoint of increasing the amount of the cosmetic material held by the cosmetic-impregnated carrier taken into the interior of the cosmetic-impregnated carrier.

[0082] In the carrier for impregnating with a cosmetic preparation, the density of the dense fibrous surface layer is set to 45 to 60 kg / m from the viewpoint of preventing a large amount of the cosmetic preparation taken into the carrier for impregnating with a cosmetic preparation from being removed at once at the beginning of use. 3 The density of the sparse fibrous substrate is about 13 to 20 kg / m 3 It is preferable that the amount is about 100%.

[0083] Furthermore, the value obtained by dividing the density of the dense fibrous surface layer by the density of the sparse fibrous base material (hereinafter referred to as the "compression ratio") is preferably 2 to 4, and more preferably 2.5 to 3.5, from the viewpoint of preventing a large amount of the cosmetic material incorporated inside the carrier for cosmetic impregnation from being removed all at once during the initial period of use.

[0084] The air resistance of the dense fibrous surface layer of the carrier to be impregnated with a cosmetic preparation is preferably 0.0125 to 0.0275 kPa s / m, and more preferably 0.0145 to 0.0255 kPa s / m, from the standpoint of preventing a large amount of the cosmetic preparation taken into the carrier to be impregnated with a cosmetic preparation from being removed all at once during the initial period of use.

[0085] The carrier for impregnating with a cosmetic preparation of the present invention can be suitably used as a cosmetic-impregnated body by retaining a cosmetic preparation in the carrier for impregnating with a cosmetic preparation. The cosmetic-impregnated body of the present invention can be suitably used for various types of cosmetics.

[0086] The carrier for being impregnated with a cosmetic preparation of the present invention has a plurality of through holes extending from the front surface to the back surface thereof. Because the carrier for being impregnated with a cosmetic preparation of the present invention has a plurality of through holes, the carrier for being impregnated with a cosmetic preparation of the present invention can be easily filled with a large amount of a cosmetic preparation, and the cosmetic preparation can be continuously and almost uniformly extracted from the cosmetic-impregnated body in which the cosmetic preparation has been filled in the carrier for being impregnated with a cosmetic preparation.

[0087] The hole size (diameter) of the through-holes of the carrier for impregnating with a high-viscosity cosmetic is preferably 0.5 mm or more, more preferably 1 mm or more, from the viewpoint of easily filling a large amount of the high-viscosity cosmetic into the carrier for impregnating with a high-viscosity cosmetic, continuously and almost uniformly extracting the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated body, and from the viewpoint of improving the visibility of the design formed by the through-holes, and is preferably 5 mm or less, more preferably 3 mm or less, and even more preferably 2.5 mm or less, from the viewpoint of easily filling a large amount of the high-viscosity cosmetic into the carrier for impregnating with a high-viscosity cosmetic, and continuously and almost uniformly extracting the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated body. Therefore, the hole size of the through-holes of the carrier for impregnating with a high-viscosity cosmetic is preferably 0.5 to 5 mm, more preferably 0.5 to 3 mm, and even more preferably 1 to 2.5 mm.

[0088] The hole size (diameter) of the through-holes of the carrier for impregnating with a low-viscosity cosmetic is preferably 0.1 mm or more, more preferably 0.2 mm or more, from the viewpoint of easily filling a large amount of the low-viscosity cosmetic into the carrier for impregnating with a low-viscosity cosmetic, continuously and substantially uniformly extracting the low-viscosity cosmetic from the low-viscosity cosmetic-impregnated body, and from the viewpoint of improving the visibility of the design formed by the through-holes, and is preferably 0.6 mm or less, more preferably 0.5 mm or less, from the viewpoint of easily filling a large amount of the low-viscosity cosmetic into the carrier for impregnating with a low-viscosity cosmetic, and continuously and substantially uniformly extracting the low-viscosity cosmetic from the low-viscosity cosmetic-impregnated body. Therefore, the hole size of the through-holes of the carrier for impregnating with a low-viscosity cosmetic is preferably 0.1 to 0.6 mm, more preferably 0.2 to 0.5 mm.

[0089] The shape of the opening of the through hole is generally circular, but the present invention is not limited to circular shapes, and may be elliptical, triangular, rectangular, hexagonal, star-shaped or other polygonal shapes. The multiple through holes may have the same opening shape or different opening shapes. When the through hole has a shape other than circular, the diameter of the through hole means the length of the longest diagonal of the shape of the through hole.

[0090] The plurality of through holes may have the same hole diameter, or may have different hole diameters.

[0091] In a carrier for impregnating with a high-viscosity cosmetic preparation, the ratio of the area of ​​all the through holes to the area of ​​the surface of the carrier for impregnating with a high-viscosity cosmetic preparation is preferably 1 to 30%, more preferably 3 to 25%, and even more preferably 5 to 20%, from the viewpoints of easily filling a large amount of the high-viscosity cosmetic preparation into the carrier for impregnating with a high-viscosity cosmetic preparation, continuously and almost uniformly extracting the high-viscosity cosmetic preparation from the high-viscosity cosmetic preparation-impregnated body, and improving the visibility of the design formed by the through holes. The surface of the carrier for impregnating with a high-viscosity cosmetic preparation is the surface on which the through holes are formed.

[0092] For example, if the diameter of the surface of the carrier for impregnating a high-viscosity cosmetic preparation is 5 cm, the surface area of ​​the carrier for impregnating a high-viscosity cosmetic preparation is about 19.6 cm 2 When the ratio of the area of ​​all the through holes to the surface area of ​​the carrier for impregnation with a high-viscosity cosmetic preparation is 20%, the area occupied by all the through holes is about 3.9 cm 2 When the diameter of the through-holes in the carrier for impregnation with a high-viscosity cosmetic preparation is 2 mm, the area of ​​one through-hole is about 0.03 cm 2 Therefore, the number of through holes on the surface of the carrier for being impregnated with a high-viscosity cosmetic preparation is about 130 (3.9 / 0.03).

[0093] In a carrier for impregnating with a low-viscosity cosmetic preparation, the ratio of the area of ​​all the through holes to the area of ​​the surface of the carrier for impregnating with a low-viscosity cosmetic preparation is preferably 0.1 to 15%, more preferably 0.2 to 13%, and even more preferably 0.5 to 10%, from the viewpoints of easily filling a large amount of the low-viscosity cosmetic preparation into the carrier for impregnating with a low-viscosity cosmetic preparation, continuously and almost uniformly extracting the low-viscosity cosmetic preparation from the low-viscosity cosmetic preparation-impregnated body, and improving the visibility of the design formed by the through holes. The surface of the carrier for impregnating with a low-viscosity cosmetic preparation is the surface on which the through holes are formed.

[0094] For example, if the diameter of the surface of a carrier for impregnating a low-viscosity cosmetic preparation is 5 cm, the surface area of ​​the carrier for impregnating a low-viscosity cosmetic preparation is approximately 19.6 cm 2 When the ratio of the area of ​​all the through holes to the surface area of ​​the carrier for impregnation with a low-viscosity cosmetic preparation is 5%, the area occupied by all the through holes is about 0.98 cm 2 When the diameter of the through hole is 0.5 mm, the area of ​​one through hole is approximately 0.0020 cm 2 Therefore, the number of through holes on the surface of the carrier for being impregnated with a low-viscosity cosmetic preparation is about 490 (0.98 / 0.0020).

[0095] The number of through holes provided on the surface of the carrier to be impregnated with a cosmetic preparation cannot be determined in general because it varies depending on the surface area of ​​the carrier to be impregnated with a cosmetic preparation, etc. It is usually preferable to adjust the number of through holes so that the ratio of the area of ​​all the through holes to the surface area of ​​the carrier to be impregnated with a cosmetic preparation and the hole diameter of the through holes are within the above-mentioned ranges.

[0096] The arrangement of the multiple through holes on the surface of the carrier for impregnating with a cosmetic preparation is arbitrary. From the viewpoint of easily filling the carrier for impregnating with a large amount of the cosmetic preparation and continuously and uniformly extracting the cosmetic preparation from the cosmetic preparation-impregnated body, the through holes are preferably formed so as to draw multiple concentric circles from the center of the carrier for impregnating with a cosmetic preparation or to draw a lattice. The through holes may also be formed so as to draw designs such as letters, logos, figures, patterns, etc. on the surface of the carrier for impregnating with a cosmetic preparation.

[0097] One embodiment of the surface design of a carrier for impregnating with a high-viscosity cosmetic material is shown in Fig. 7. Figs. 7(a) to (e) are schematic plan views showing one embodiment of the surface design of a carrier for impregnating with a high-viscosity cosmetic material, respectively, but the present invention is not limited to only these embodiments. Also, one embodiment of the surface design of a carrier for impregnating with a low-viscosity cosmetic material is shown in Fig. 8. Figs. 8(a) to (c) are schematic plan views showing one embodiment of the surface design of a carrier for impregnating with a low-viscosity cosmetic material, respectively, but the present invention is not limited to only these embodiments. As shown in Figs. 7 and 8, a carrier 1 for impregnating with a high-viscosity cosmetic material and a carrier 3 for impregnating with a low-viscosity cosmetic material each have a through hole 2 or a through hole 4 that forms a desired design.

[0098] Methods for forming through holes in the surface of the carrier for being impregnated with a cosmetic preparation include, for example, a method in which a laser beam is irradiated onto the surface of the carrier for being impregnated with a cosmetic preparation to form through holes passing through from the surface to the back surface of the carrier for being impregnated with a cosmetic preparation, and a method in which a punching process is performed on the surface of the carrier for being impregnated with a cosmetic preparation using a Thomson die to form through holes passing through from the surface to the back surface of the carrier for being impregnated with a cosmetic preparation, but the present invention is not limited to these examples.

[0099] The carrier for being impregnated with a cosmetic preparation of the present invention formed as described above can easily be filled with a large amount of a cosmetic preparation.

[0100] The cosmetic-impregnated body of the present invention is a cosmetic material contained in the carrier for impregnation of a cosmetic material of the present invention. Since the cosmetic-impregnated body of the present invention uses the carrier for impregnation of a cosmetic material of the present invention, the cosmetic material can be continuously and almost uniformly extracted.

[0101] The cosmetic-impregnated body of the present invention can be used as a high-viscosity cosmetic-impregnated body or a low-viscosity cosmetic-impregnated body. The high-viscosity cosmetic-impregnated body means a cosmetic-impregnated body containing a high-viscosity cosmetic. The low-viscosity cosmetic-impregnated body means a cosmetic-impregnated body containing a low-viscosity cosmetic. In the present invention, the cosmetic-impregnated body is a concept that includes both a high-viscosity cosmetic-impregnated body and a low-viscosity cosmetic-impregnated body.

[0102] Examples of cosmetics that can be used in the cosmetic-impregnated body include foundation, concealer, highlighter, control color, makeup base, eyeshadow, eyeliner, mascara, blusher, face powder, eyebrow pencil, cleansing cream, cleansing milk, cleansing liquid, face wash cream, face wash foam, massage cream, cold cream, vanishing cream, skin cream, skin gel, milky lotion, skin lotion, beauty serum, various lotions, sunscreen, body cream, body oil, hair shampoo, hair rinse, hair conditioner, hair treatment, hair liquid, hair tonic, etc., but the present invention is not limited to only these examples. Among these cosmetics, liquid cosmetics are preferred from the viewpoint of continuously and uniformly extracting the cosmetic from the cosmetic-impregnated body.

[0103] The amount of high-viscosity cosmetic used in the high-viscosity cosmetic-impregnated body varies depending on the type of carrier for impregnating the high-viscosity cosmetic and cannot be determined in general terms. For example, if the carrier for impregnating the high-viscosity cosmetic is a liquid foundation, about 10 to 20 g of liquid foundation with a viscosity of 20,000 mPa s at 25°C can be used in a high-viscosity cosmetic-impregnated body that is 5 cm in diameter and 1.5 cm thick.

[0104] The amount of low-viscosity cosmetic used in a low-viscosity cosmetic-impregnated body varies depending on the type of carrier for impregnating the low-viscosity cosmetic and cannot be determined in general terms; however, for example, if the carrier for impregnating the low-viscosity cosmetic is a liquid foundation, approximately 10 to 20 g of liquid foundation with a viscosity of 10,000 mPa s at 25°C can be used in a low-viscosity cosmetic-impregnated body that is 5 cm in diameter and 1.5 cm thick.

[0105] The cosmetic of the present invention comprises the cosmetic-impregnated body of the present invention. Since the cosmetic of the present invention comprises the cosmetic-impregnated body, the cosmetic can be continuously and almost uniformly extracted from the cosmetic-impregnated body. The cosmetic of the present invention may have a storage section for storing the cosmetic-impregnated body, and the cosmetic-impregnated body of the present invention may be stored in the storage section. Examples of the cosmetic include cosmetic compacts, but the present invention is not limited to these examples. EXAMPLES

[0106] Next, the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.

[0107] Manufacturing Example 1 A core-sheath composite fiber (core component: polyethylene terephthalate, sheath component: thermoplastic polyethylene terephthalate, fineness: 6 denier) and polyester fiber (resin: polyethylene terephthalate, fineness: 3 denier) were mixed in a mass ratio of 70:30 so that the fibers were parallel to each other, and the sheath component was heated and melted while being pressed to produce a carrier for impregnating high-viscosity cosmetics. The carrier for impregnating high-viscosity cosmetics was subjected to cutting processing to produce a cylindrical sample A (density: 18.0 kg / m) with a three-dimensional structure with a diameter of about 5 cm and a thickness of about 1 cm. 3 ) was obtained.

[0108] When the flat surface of sample A obtained above was stretched in the direction in which the fibers ran parallel, stripes due to the parallel arrangement of the fibers were observed, but no stripes were observed when the sample was stretched perpendicular to the parallel direction.

[0109] Next, the plane and side of the sample A obtained above were observed with an optical microscope. As a result, it was confirmed that the fiber density was higher on the side than on the plane of sample A, and that lumpy (amoeba-like) fused parts were formed at the contact points between the constituent fibers.

[0110] Manufacturing Example 2 A core-sheath composite fiber (core component: polyethylene terephthalate, sheath component: thermoplastic polyethylene terephthalate, fineness: 6 denier) and polyester fiber (resin: polyethylene terephthalate, fineness: 3 denier) were mixed in a mass ratio of 70:30 so that the fibers were parallel to each other, and the sheath component was heated and melted while being pressed to produce a carrier for impregnating with high-viscosity cosmetics. The carrier for impregnating with high-viscosity cosmetics was subjected to cutting processing to produce a cylindrical sample B (density: 24.0 kg / m) with a three-dimensional structure with a diameter of about 5 cm and a thickness of about 1 cm. 3 ) was obtained.

[0111] When the flat surface of the sample B obtained above was stretched in the direction in which the fibers run parallel to each other, stripes due to the parallel arrangement of the fibers were observed, but when the sample was stretched in the direction perpendicular to the parallel arrangement, stripes were not observed. Also, as with the sample A obtained in Production Example 1, it was confirmed that lumpy (amoeba-like) fused parts were formed at the contact parts between the constituent fibers.

[0112] Production Example 3 A web (thickness: 16 mm) was prepared by blending core-sheath composite fibers (core component: polyethylene terephthalate, sheath component: thermoplastic polyethylene terephthalate, fineness: 6 denier) and polyester fibers (resin: polyethylene terephthalate, fineness: 3 denier) in a mass ratio of 50:50 with the fibers arranged parallel to each other.

[0113] The web was sandwiched between a press laminator (heat press machine), and only one surface of the press laminator was heated to 219°C. The sheath component was heated and melted for 72 seconds while the web was pressed, forming a dense layer 1.5 mm thick on one surface, producing a carrier for impregnation of a high-viscosity cosmetic preparation in which a dense fibrous surface layer made of the web and a sparse fibrous base material made of the web are integrated.

[0114] Next, the carrier for impregnation with high-viscosity cosmetics obtained above was subjected to cutting processing to obtain a cylindrical sample C (density: 16.4 kg / m) having a three-dimensional structure with a diameter of about 5 cm and a thickness of about 1 cm. 3 ) was obtained.

[0115] When the flat surface of the sample C obtained above was stretched in the direction in which the fibers run parallel to each other, stripes due to the parallel arrangement of the fibers were observed, but when the sample C was stretched in the direction perpendicular to the parallel arrangement, stripes were not observed. Also, as with the sample A obtained in Production Example 1, it was confirmed that the fused portions in the form of clumps (amoeba-like) were formed at the contact points between the constituent fibers in the sample C.

[0116] Examples 1 to 7 Using Sample A obtained in Production Example 1, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of Sample A had the arrangement shown in Table 1. Table 1 shows the pore size of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above and the ratio of the area of ​​all the through holes to the surface area (hereinafter referred to as "area ratio").

[0117] Example 8 Using sample A obtained in Production Example 1, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming each through hole using a Thomson mold so that, as through holes extending from the front surface to the back surface of sample A, 8 through holes with a diameter of 1 mm were formed in the center, 4 through holes with a diameter of 1.5 mm were formed concentrically around the periphery of the through hole with a diameter of 1 mm, and 15 through holes with a diameter of 2 mm were formed concentrically around the periphery of the through hole with a diameter of 1.5 mm. The hole diameters and area ratios of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 1.

[0118] Comparative Example 1 Sample A obtained in Production Example 1 was used as it is as a carrier for impregnation with a high-viscosity cosmetic preparation.

[0119] [Table 1]

[0120] Examples 9 to 15 Using Sample B obtained in Production Example 2, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of Sample B had the arrangement shown in Table 2. The pore size and area ratio of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 2.

[0121] Comparative Example 2 Sample B obtained in Production Example 2 was used as it is as a carrier for impregnation with a high-viscosity cosmetic preparation.

[0122] [Table 2]

[0123] Examples 16 to 22 Using Sample C obtained in Production Example 3, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of Sample C had the arrangement shown in Table 3. The hole diameters and area ratios of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 3.

[0124] Comparative Example 3 Sample C obtained in Production Example 3 was used as it is as a carrier for impregnation with a high-viscosity cosmetic preparation.

[0125] Comparative Example 4 A polyurethane foam (Kuraray Industries, Inc., product number: 301WH) was cut to obtain Sample D with a diameter of about 5 cm and a thickness of about 1 cm. Sample D obtained above was used as a carrier for impregnation of a high-viscosity cosmetic preparation.

[0126] Comparative Example 5 Using sample D obtained in Comparative Example 4, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of sample D had the arrangement shown in Table 3. The pore size and area ratio of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 3.

[0127] Comparative Example 6 An acrylonitrile-butadiene rubber foam (manufactured by Taiki Co., Ltd.) was cut to obtain Sample E having a diameter of about 5 cm and a thickness of about 1 cm. Sample E thus obtained was used as a carrier for impregnation with a high-viscosity cosmetic preparation.

[0128] Comparative Example 7 Using Sample E obtained in Comparative Example 6, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of Sample E had the arrangement shown in Table 3. The hole diameters and area ratios of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 3.

[0129] [Table 3]

[0130] Test Example 1 The carriers for impregnating high-viscosity cosmetics obtained in Examples 1 to 22 and Comparative Examples 1 to 7 were filled with high-viscosity cosmetics, and the degree of removal of the high-viscosity cosmetics from the high-viscosity cosmetic-impregnated bodies (uniformity of amount removed) were evaluated according to the following methods. The results are shown in Table 4.

[0131] (1) Filling ability of high-viscosity cosmetics The carrier for impregnating high-viscosity cosmetics was placed in an inner case, and 17 g of high-viscosity cosmetics (viscosity at 25°C: 20,000 mPa s) was filled into the carrier for impregnating high-viscosity cosmetics using a manual cream filling machine to produce a high-viscosity cosmetic-impregnated body. The filling ability of the high-viscosity cosmetics was evaluated based on the following evaluation criteria. [Evaluation Criteria] ◯: The high-viscosity cosmetic can be easily filled into the carrier for impregnation with the high-viscosity cosmetic. Δ: It takes a little time to fill the high-viscosity cosmetic into the carrier for impregnation with the high-viscosity cosmetic. ×: It is difficult to fill the high-viscosity cosmetic material into the carrier for impregnation with the high-viscosity cosmetic material.

[0132] (2) Uniformity of amount removed The carrier for impregnating high-viscosity cosmetic preparations obtained in the above "(1) Filling property of high-viscosity cosmetic preparations" was left to stand for 1 hour after production. The carrier for impregnating high-viscosity cosmetic preparations was rubbed with a puff, and the cosmetic preparation attached to the puff was applied to the nonwoven fabric. This operation was counted as one cycle, and the amount of cosmetic preparation removed was checked every 30 cycles.

[0133] In addition, the column "Amount of cosmetic removed" in Table 4 shows the amount (g) of cosmetic removed when the above operation was repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times.

[0134] [Table 4]

[0135] Next, based on the results shown in Table 4, the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 1 to 6, Example 8, and Comparative Example 1 are shown in FIG. 1, the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 9 to 14 and Comparative Example 2 are shown in FIG. 2, and the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 16 to 21 are shown in FIG. 3.

[0136] (a) to (h) in Fig. 1 respectively show the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 1 to 6, Example 8, and Comparative Example 1. (a) to (g) in Fig. 2 respectively show the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 9 to 14 and Comparative Example 2. (a) to (f) in Fig. 3 respectively show the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 16 to 21.

[0137] From the results shown in Table 4, it can be seen that the carriers for impregnation with high-viscosity cosmetics obtained in each Example were all rated as △ or ◯ for their loading ability with high-viscosity cosmetics, and therefore can be easily loaded with large amounts of high-viscosity cosmetics.

[0138] In contrast, the carriers for impregnating with high-viscosity cosmetic preparations obtained in each comparative example were all rated as × for the filling ability of high-viscosity cosmetic preparations, indicating that it is difficult to fill them with high-viscosity cosmetic preparations. Also, the carriers for impregnating with high-viscosity cosmetic preparations in which polyurethane foam is used (Comparative Examples 4 and 5) and the carriers for impregnating with high-viscosity cosmetic preparations in which acrylonitrile-butadiene rubber foam is used (Comparative Examples 6 and 7) were rated as × for the filling ability of high-viscosity cosmetic preparations, indicating that when these foams are used as carriers for impregnating with high-viscosity cosmetic preparations, they have poor filling ability regardless of the presence or absence of through holes.

[0139] In addition, from the results shown in Table 4 and Figures 1 to 3, the high-viscosity cosmetic-impregnated bodies obtained using the carriers for impregnation of high-viscosity cosmetic materials obtained in Examples 1 to 6, Examples 8 to 14, and Examples 16 to 21 were all rated as ◯ for the filling ability of high-viscosity cosmetic materials, and it is possible to continuously and almost uniformly extract high-viscosity cosmetic materials. Therefore, it is evident that the cosmetics using the high-viscosity cosmetic-impregnated bodies obtained in these Examples allow high-viscosity cosmetic materials to be continuously and almost uniformly extracted.

[0140] According to Figures 1(f) and (g), Figure 2(c) and Figure 3(a), when the above operation was repeated 91 to 120 times, the amount of cosmetic removed decreased. This decrease in the amount removed was due to the fact that a small amount of the high-viscosity cosmetic remained.

[0141] Examples 23 to 27 Using Sample A obtained in Production Example 1, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of Sample A had the arrangement shown in Table 5. The pore size and area ratio of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 5.

[0142] Comparative Example 8 Sample A obtained in Production Example 1 was used as it is as a carrier for impregnation with a high-viscosity cosmetic preparation.

[0143] [Table 5]

[0144] Examples 28 to 31 Using Sample B obtained in Production Example 2, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of Sample B had the arrangement shown in Table 6. The pore size and area ratio of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 6.

[0145] Comparative Example 9 Sample B obtained in Production Example 2 was used as it is as a carrier for impregnation with a high-viscosity cosmetic preparation.

[0147] Examples 32 to 35 Using Sample C obtained in Production Example 3, a carrier for impregnating with high-viscosity cosmetic preparations was obtained by forming through holes using a Thomson mold so that the through holes extending from the front surface to the back surface of Sample C had the arrangement shown in Table 7. The hole diameters and area ratios of the through holes of the carrier for impregnating with high-viscosity cosmetic preparations obtained above are shown in Table 7.

[0148] [Table 7]

[0149] Test Example 2 The carriers for impregnating high-viscosity cosmetics obtained in Examples 23 to 35 and Comparative Examples 8 to 9 were filled with high-viscosity cosmetics, and the degree of removal of the high-viscosity cosmetics from the high-viscosity cosmetic-impregnated bodies was evaluated according to the following methods. The results are shown in Table 8.

[0150] (1) Filling ability of high-viscosity cosmetics The carrier for impregnating high-viscosity cosmetics was placed in an inner case, and 17 g of high-viscosity cosmetics (viscosity at 25°C: 50,000 mPa s) was filled into the carrier for impregnating high-viscosity cosmetics using a manual cream filling machine to produce a high-viscosity cosmetic-impregnated body. The filling ability of the high-viscosity cosmetics was evaluated based on the following evaluation criteria.

[0151] [Evaluation Criteria] ◯: The high-viscosity cosmetic can be easily filled into the carrier for impregnation with the high-viscosity cosmetic. Δ: It takes a little time to fill the high-viscosity cosmetic into the carrier for impregnation with the high-viscosity cosmetic. ×: It is difficult to fill the high-viscosity cosmetic material into the carrier for impregnation with the high-viscosity cosmetic material.

[0152] (2) Removal of high-viscosity cosmetics from the body impregnated with the high-viscosity cosmetics The carrier for impregnating high-viscosity cosmetic preparations obtained in the above "(1) Filling property of high-viscosity cosmetic preparations" was left to stand for 1 hour after production. The carrier for impregnating high-viscosity cosmetic preparations was rubbed with a puff, and the cosmetic preparation attached to the puff was applied to the nonwoven fabric. This cycle was repeated, and the amount of cosmetic preparation removed was checked every 30 cycles.

[0153] In addition, the column "Amount of cosmetic removed" in Table 8 shows the amount (g) of cosmetic removed when the above operation was repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times.

[0154] [Table 8]

[0155] Next, based on the results shown in Table 8, the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 23 to 26 and Comparative Example 8 are shown in FIG. 4, the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 28 to 30 and Comparative Example 9 are shown in FIG. 5, and the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 32 to 34 are shown in FIG. 6.

[0156] (a) to (e) in Fig. 4 respectively show the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 23 to 26 and Comparative Example 8. (a) to (d) in Fig. 5 respectively show the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 28 to 30 and Comparative Example 9. (a) to (c) in Fig. 6 respectively show the measurement results of the degree of removal of the high-viscosity cosmetic from the high-viscosity cosmetic-impregnated bodies obtained in Examples 32 to 34.

[0157] From the results shown in Table 8, it can be seen that the carriers for impregnation with high-viscosity cosmetics obtained in each Example were all rated as △ or O for their loading ability with high-viscosity cosmetics, and therefore can be easily loaded with large amounts of high-viscosity cosmetics.

[0158] In contrast, the carriers for impregnation with high-viscosity cosmetics obtained in each of the comparative examples were all rated as × for their ability to be filled with high-viscosity cosmetics, indicating that it is difficult to fill them with high-viscosity cosmetics.

[0159] In addition, from the results shown in Table 8 and Figures 4 to 6, the high-viscosity cosmetic-impregnated bodies obtained using the carriers for impregnation with high-viscosity cosmetic materials obtained in Examples 23 to 26, Examples 28 to 30, and Examples 32 to 34 were all rated as ◯ for the filling ability of the high-viscosity cosmetic material, and it is possible to continuously and almost uniformly extract the high-viscosity cosmetic material. Therefore, it is evident that the cosmetics using the high-viscosity cosmetic-impregnated bodies obtained in these Examples allow the high-viscosity cosmetic material to be continuously and almost uniformly extracted.

[0160] In addition, in Figures 4(a) and 5(c), when the cycle was repeated 91 to 120 times, the amount of cosmetic removed decreased. This decrease in the amount removed was due to the fact that a small amount of high-viscosity cosmetic remained.

[0161] Examples 36 to 40 A laser beam was applied to the surface of Sample A obtained in Production Example 1 using a laser processing machine (Universal Laser Systems, product number: VLS2.30) to form through-holes having the arrangement shown in Table 11, thereby obtaining a carrier for impregnating with high-viscosity cosmetic preparations. The hole diameters and area ratios of the through-holes in the obtained carrier for impregnating with high-viscosity cosmetic preparations are shown in Table 9.

[0162] The surface designs of the carriers for impregnating with high-viscosity cosmetic preparations obtained in Examples 36 to 40 are shown in Fig. 7. In Fig. 7, (a) is the surface design of carrier 1a for impregnating with high-viscosity cosmetic preparations having through-holes 2a obtained in Example 36, (b) is the surface design of carrier 1b for impregnating with high-viscosity cosmetic preparations having through-holes 2b obtained in Example 37, (c) is the surface design of carrier 1c for impregnating with high-viscosity cosmetic preparations having through-holes 2c obtained in Example 38, (d) is the surface design of carrier 1d for impregnating with high-viscosity cosmetic preparations having through-holes 2d obtained in Example 39, and (e) is the surface design of carrier 1e for impregnating with high-viscosity cosmetic preparations having through-holes 2e obtained in Example 40.

[0163] When high-viscosity cosmetics were filled into the carriers for impregnating high-viscosity cosmetics obtained in Examples 36 to 40, the loading property of the cosmetics and the degree of removal of the high-viscosity cosmetics from the high-viscosity cosmetic-impregnated bodies were examined in the same manner as in Test Example 1. The evaluation results of the loading property of the cosmetics are shown in Table 9.

[0164] [Table 9]

[0165] From the results shown in Table 9, the carriers for impregnation with high-viscosity cosmetic preparations obtained in each Example were all rated as ◯ for the loading ability of the high-viscosity cosmetic preparation, which indicates that the high-viscosity cosmetic preparation can be loaded easily in large amounts. In addition, it was confirmed that the removal of the high-viscosity cosmetic preparation was excellent, similar to Example 1.

[0166] From the above results, it can be seen that when the pore size of the carrier for impregnation with high-viscosity cosmetics is preferably set to 0.5 to 5 mm, more preferably 0.5 to 3 mm, and even more preferably 1 to 2.5 mm, and the ratio of the area of ​​all through holes to the surface area is preferably set to 1 to 30%, more preferably 3 to 25%, and even more preferably 5 to 20%, the porosity is improved and therefore the filling ability of the high-viscosity cosmetic is improved.

[0167] Therefore, by setting the pore size and the ratio of the area of ​​all through holes to the surface area of ​​the carrier for impregnation with high-viscosity cosmetics so that they are within the above-mentioned ranges, the amount of high-viscosity cosmetic material removed after a given number of times (e.g., 30 times) becomes uniform, and it can be seen that the amount of high-viscosity cosmetic material removed can be appropriately adjusted to the desired amount.

[0168] Examples 41 to 54 A laser beam was irradiated onto the surface of Sample A obtained in Production Example 1 using a laser processing machine (Universal Laser Systems, product number: VLS2.30) to form through-holes having the arrangement shown in Table 10, thereby obtaining a carrier for impregnating with a low-viscosity cosmetic preparation. The hole diameters and area ratios of the through-holes in the carrier for impregnating with a low-viscosity cosmetic preparation obtained above are shown in Table 10.

[0169] The carriers for being impregnated with low-viscosity cosmetics obtained in Examples 42, 45 and 48 each had the surface designs shown in Figs. 8(a) to (c).

[0170] Comparative Example 10 A laser beam was irradiated onto the surface of Sample D obtained in Comparative Example 4 using a laser processing machine (Universal Laser Systems, product number: VLS2.30) to form through-holes having the arrangement shown in Table 10, thereby obtaining a carrier for impregnating with a low-viscosity cosmetic preparation. The hole diameters and area ratios of the through-holes of the obtained carrier for impregnating with a low-viscosity cosmetic preparation are shown in Table 10.

The results are shown in Table 11.

[0175] (2) Shape of the through hole Immediately after irradiation with the laser beam, the surface design of the carrier for impregnation with a low-viscosity cosmetic preparation was observed with the naked eye, and the shape of the through holes was evaluated based on the following evaluation criteria. [Evaluation Criteria] ◯: No residue was found in the through-hole, and the through-hole was of good shape. △: A small amount of residue was present in the through-holes, and some of the through-holes were slightly blocked. ×: Most of the through holes are blocked by residue.

[0176] (3) Filling ability of low-viscosity cosmetics The carrier for impregnating a low-viscosity cosmetic was placed in an inner case, and 17 g of a low-viscosity cosmetic (viscosity at 25°C: 5000 mPa s), 17 g of a low-viscosity cosmetic (viscosity at 25°C: 10000 mPa s), or 17 g of a low-viscosity cosmetic (viscosity at 25°C: 19000 mPa s) was filled into the carrier for impregnating a low-viscosity cosmetic using a manual cream filling machine to produce a low-viscosity cosmetic-impregnated body. The filling ability of the low-viscosity cosmetic at this time was evaluated based on the following evaluation criteria.

[0177] [Evaluation Criteria] ◯: The low-viscosity cosmetic can be easily filled into the carrier for impregnation with the low-viscosity cosmetic. Δ: It takes a little time to fill the low-viscosity cosmetic into the carrier for impregnation with the low-viscosity cosmetic. ×: It is difficult to fill the low-viscosity cosmetic material into the carrier for impregnation with the low-viscosity cosmetic material.

[0178] (4) Uniformity of amount removed The carrier for impregnating low-viscosity cosmetics (viscosity at 25°C: 10,000 mPa·s) obtained in the above "(3) Filling property of low-viscosity cosmetics" was produced and then allowed to stand for 1 hour. The carrier for impregnating low-viscosity cosmetics was rubbed with a puff, and the low-viscosity cosmetic adhering to the puff was applied to a nonwoven fabric, which constituted one cycle. This operation was repeated, and the amount (g) of the low-viscosity cosmetic removed was examined every 30 operations. More specifically, as in the above "(2) Uniformity of amount removed", the amount (g) of the low-viscosity cosmetic removed was examined when the operation was repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times. The uniformity of the amount of the low-viscosity cosmetic removed at this time was evaluated based on the following evaluation criteria.

[0179] [Evaluation Criteria] Good: The amount of low-viscosity cosmetic removed is uniform. More specifically, the amount of low-viscosity cosmetic removed when the above operation is repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times is within the range of 1.0 g or more and 5.0 g or less. Δ: The amount of low-viscosity cosmetic removed is almost uniform. More specifically, when the above operation is repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times, the amount of low-viscosity cosmetic removed is 0.5 g or more and less than 1.0 g, or more than 5.0 g and 6.0 g or less. ×: The amount of low-viscosity cosmetic removed is non-uniform. More specifically, when the above operation is repeated 1 to 30 times, 31 to 60 times, 61 to 90 times, or 91 to 120 times, the amount of low-viscosity cosmetic removed is less than 0.5 g or exceeds 6.0 g.

[0180] [Table 11]

[0181] From the results shown in Table 11, the carriers for impregnating low-viscosity cosmetic preparations obtained in each Example were all rated as ◯ or △ in visibility, indicating that they have excellent visibility of the design. In addition, the carriers for impregnating low-viscosity cosmetic preparations obtained in each Example were rated as ◯ or △ in shape of the through holes, indicating that they are easy to fill with the low-viscosity cosmetic preparation and that the low-viscosity cosmetic preparation can be continuously and almost uniformly dispensed. In contrast, the carrier for impregnating low-viscosity cosmetic preparations obtained in Comparative Example 10 was rated as × in shape of the through holes, indicating that it is difficult to fill with the low-viscosity cosmetic preparation and that it is difficult to continuously and almost uniformly dispense the low-viscosity cosmetic preparation.

[0182] Furthermore, from the results shown in Table 11, the carriers for impregnation with low-viscosity cosmetic preparations obtained in each Example were all rated as ◯ for their ability to be filled with low-viscosity cosmetic preparations, indicating that they can be easily filled with large amounts of low-viscosity cosmetic preparations. In contrast, some of the carriers for impregnation with low-viscosity cosmetic preparations obtained in Comparative Example 10 were rated as × for their ability to be filled with low-viscosity cosmetic preparations, indicating that it is difficult or impossible to fill with low-viscosity cosmetic preparations.

[0183] From the above results, it can be seen that when the pore size of the carrier for impregnating with low-viscosity cosmetic preparations is preferably set to 0.1 to 0.6 mm, more preferably 0.2 to 0.5 mm, and the ratio of the area of ​​all through holes to the surface area is preferably set to 0.1 to 15%, more preferably 0.2 to 13%, and even more preferably 0.5 to 10%, the visibility of the surface design of the carrier for impregnating with low-viscosity cosmetic preparations and the filling ability of the low-viscosity cosmetic preparation are improved, and the low-viscosity cosmetic preparation can be continuously and almost uniformly dispensed. In particular, when a three-dimensional structure is formed with composite fibers and the pore size and the ratio of the area of ​​all through holes to the surface area are set to satisfy the above-mentioned ranges, it can be seen that the visibility of the surface design of the carrier for impregnating with low-viscosity cosmetic preparations and the filling ability of the low-viscosity cosmetic preparation are improved, and the low-viscosity cosmetic preparation can be continuously and almost uniformly dispensed.

[0184] Furthermore, when the pore size and the ratio of the area of ​​all through holes to the surface area of ​​the carrier for impregnation with a low-viscosity cosmetic preparation are set to be within the above-mentioned ranges, the amount of low-viscosity cosmetic preparation removed per given number of times becomes uniform, and it can be seen that the amount of low-viscosity cosmetic preparation that can be removed as desired is able to be appropriately adjusted. In particular, when a three-dimensional structure is formed with composite fibers and the pore size and the ratio of the area of ​​all through holes to the surface area are set to be within the above-mentioned ranges, it can be seen that the amount of low-viscosity cosmetic preparation that can be removed as desired is able to be appropriately adjusted.
