Description

Cosmetic composition carrier

This application claims priority to Korean Patent Application No. 10-2018-0152845 filed on November 30, 2018, the entire contents of which are incorporated herein by reference. In addition, this application claims priority to Korean Patent Application No. 10-2019-0116199 filed on September 20, 2019, the entire contents of which are incorporated herein by reference.

This specification describes a cosmetic composition carrier.

A global market expansion of so-called cushion fact cosmetics in which a liquid cosmetic composition is loaded onto a carrier and placed in a fact type container is underway. A carrier suitable for such a cushion pact cosmetic should be easily filled with a cosmetic composition, capable of carrying the composition homogeneously for a long time, and when the cosmetic composition is taken from the carrier, an appropriate amount will be uniformly discharged, and the contents can be used to the end. Until then, physical properties such as long-term discharge amount will be kept uniform. In addition, since it is a beauty product, aesthetic needs such as color and design of the exterior must also be satisfied.

In order to satisfy these needs, the carrier may have a layered structure, so that the upper and lower carriers have different physical properties. However, when a generally known adhesive is used for attaching carriers having different materials and/or properties to each other, due to porosity, an actual adhesive is applied and the area to be adhered is reduced, so adhesion durability may not be sufficient. In addition, when the adhesive strength is not sufficient, the cosmetic composition may be loaded therein to cause a problem in which the adhered portion falls during long-term storage. Furthermore, if a large amount of adhesive is used for sufficient adhesion, the porous structure of the carrier becomes clogged, which may cause a problem of not properly functioning as a carrier.

Hereinafter, exemplary embodiments of the present application will be described in detail with reference to the accompanying drawings. However, the technology disclosed in the present application is not limited to the embodiments described herein and may be embodied in other forms. However, the embodiments introduced herein are provided to ensure that the disclosed contents are thorough and complete and that the spirit of the present application is sufficiently conveyed to those skilled in the art. In order to clearly express each component in the drawings, the size of the component, such as width or thickness, is slightly enlarged. Also, for convenience of description, only a part of components are illustrated, but those skilled in the art will be able to easily grasp the rest of the components. In addition, those of ordinary skill in the art may implement the spirit of the present application in various other forms without departing from the technical spirit of the present application.

As used herein, "impregnating material" means that the cosmetic composition can be absorbed and supported therein, and may also be expressed as "carrier", "carrier" or "media". In one example, the impregnating material may be used by discharging the material supported therein to a separate applicator.

In the present specification, the term “applying sphere” means used to deliver the cosmetic composition to the skin to be applied, etc., and may also be expressed as “applying means”, “applying sponge”, or “applicator”. In one example, the applicator may include puffs, tips, brushes, and the like.

In the present specification, the viscosity may be measured by using a Brookfield Viscometer Model DV3T Brookfield Viscometer Model DV3T) at a temperature of 30°C for 64 spindles and 12 rpm for 1 minute.

In this specification, "open cell" is a cell included in a foam, and means a cell that is entirely open, and "semi-open cell" means that at least a portion of the cell is "Open cell" means "closed cell" means a cell in which at least a portion of the cell is closed, and "reticulated structure" means a closed cell, a semi-open cell, or It is formed through a reticulation process that removes the cell walls in the foam of the open cell, which means that it has the same structure as a net with few cell walls. The closed cell has a structure in which the cell structure as the foam is foamed is maintained in a small balloon shape, so that the air is impermeable. The reticulated structure has a structure in which the membranes (walls) of balloon-shaped pore cells after foaming are removed by reticulation, so that not only air permeation but also absorption and discharge of liquid phases is possible.

In the present specification, "polyurethane foam" is solidified after foaming polyurethane, and may also be referred to as "urethane foam".

In this specification, "pore size" may be an average value of pores of a foam, that is, a cell diameter measured by an optical microscope (NIKON ECLIPSE 80i).

In the present specification, “the number of pores” refers to the number of cells in the unit line of the form. The number of pores refers to the number of pores per inch (ppi) per inch of the foam, and means the number of pores present in a line of 1 inch.

In this specification, the "hardness" of the foam is the hardness measured by an asker (ASKER, manufacturer) durometer hardness (F type (F)), the hardness before the cosmetic composition is supported on the foam it means.

Physical properties required as an impregnating material include, for example, absorbency, filling capacity, loading capacity, durability, and discharge capacity.

Absorption in this specification means that the impregnating material absorbs the cosmetic composition and is uniformly supported throughout the impregnating material. The high water absorption is excellent in compatibility between the impregnating material and the cosmetic composition, and the higher the water absorption, the more it can suppress evaporation of the cosmetic composition when stored under high temperature conditions.

The filling ability in the present specification means that the cosmetic composition is easily and uniformly supported throughout the impregnating material when the cosmetic composition is filled into the impregnating material. The excellent filling ability means that the cosmetic composition is uniformly filled at a high speed when the cosmetic composition is filled under the same conditions and pressure.

In this specification, the loading ability refers to the ability of the impregnating material to retain and maintain the cosmetic composition. The excellent holding ability means that the cosmetic composition is uniformly supported for a long period of time. The impregnating ability of the impregnating material is distinguished from being temporarily taken out of the applicator for delivery of the cosmetic composition and temporarily applied to the applicator.

Durability herein includes chemical durability and physical durability. Chemical durability refers to a property in which the impregnating material is maintained in an initial state without deformation such as damage or expansion, such as melting or tearing of the impregnating material when the cosmetic composition is left for a certain period of time at a predetermined temperature while the cosmetic composition is supported. Physical durability refers to a property that withstands physical impulses to the impregnating material, for example, pressure and friction applied to the impregnating material when the applicator is repeatedly contacted and pressured to the impregnating material for taking out the cosmetic composition. Therefore, the high durability means that the impregnating material remains impregnated with the cosmetic composition for a long period of time under a certain condition without deformation or damage, and it can maintain its original state without damaging or deforming the impregnating material even if it is repeatedly subjected to physical friction and pressure by the applicator. it means.

The discharge capacity in the present specification means the ability of the cosmetic composition carried inside the impregnating material to be discharged in an appropriate amount when used. For example, the discharge capacity may be represented by the amount of the cosmetic composition on the applicator by contacting the applicator with the impregnating material at a constant pressure. If the discharge capacity is too high or low, it is difficult to use because the cosmetic composition is excessively smeared or only a small amount is applied, so it is preferable to have a proper discharge capacity so that an appropriate amount of the cosmetic composition can be discharged depending on the pressure applied to the impregnating material.

The cosmetic composition carrier according to an embodiment of the present invention includes a laminated portion in which a plurality of polyurethane foams are stacked, and may have a junction formed at an edge.

1 schematically illustrates a cross-sectional schematic view of a cosmetic composition carrier according to an embodiment of the present invention. The cosmetic composition carrier 100 according to the present embodiment includes a lamination part including a plurality of polyurethane foams 110 and 120, and a junction 140 marked with a hatch is formed at the edge of the foam to integrally join the lamination part. can do.

The laminated portion may include two or more polyurethane foams. In one example, the laminate may include a plurality of polyurethane foams having different pore sizes, density, thickness, and number of pores different from each other.

The polyurethane may be prepared by reaction of a polyol having two or more hydroxyl groups and a polyisocyanate. The polyol may use polyether polyol, polyester polyol, polycarbonate polyol, polyolefin polyol, and polyether-based polyurethane foam, polyester-based polyurethane foam, polycarbonate-based polyurethane foam, and polyolefin-based depending on the polyol used. It is divided into polyurethane foam.

When the whole includes a single foam having the same physical properties as a carrier, there is a problem that the discharge amount is uneven depending on the point of use of the supported cosmetic composition. Specifically, compared to the initial use, the amount is reduced according to consumption of the supported cosmetic composition, and after taking the cosmetic composition at least about 50% by weight of the initial use, the degree of discharge may drop rapidly. In addition, when a single foam is included as a carrier, since the pore size is relatively large, as the number of discharges is repeated, different amounts of cosmetic compositions are discharged at each discharge, so the discharge pattern may not be uniform. Cosmetic composition according to an embodiment of the present invention The single foam described above until the use of a weight of 50% or more compared to the initial use, including a plurality of polyurethane foams having one or more different pore sizes, density, thickness, and number of pores as a layer structure Compared to the case, the discharge degree of the cosmetic composition may be maintained uniformly.

The stacked portion may include a multilayer, specifically 2 to 20, more specifically 2 to 10, and even more specifically 2 to 5 polyurethane foams.

The stacked portion may include a polycarbonate-based polyurethane foam on the uppermost layer, that is, when the direction in which the cosmetic composition is discharged from the carrier during use is upper. The polyurethane foam 110 in the schematic diagram of FIG. 1 and the polyurethane foam 210 in the schematic diagrams of FIGS. 2 to 4 correspond to this.

The polycarbonate-based polyurethane foam has chemical resistance and chemical resistance as compared with polyether-based and polyester-based polyurethane foams, and may exhibit high physical properties such as durability. Since it corresponds to the use portion where the cosmetic composition is discharged during use, it can be used without long-term deformation due to its excellent durability even when physical contact for taking out the cosmetic composition is repeated.

The cosmetic composition is impregnated into the pores of the carrier and discharged by external force. In this case, if the cell structure of the foamed foam is closed cell, impregnation and discharge of the cosmetic composition cannot be made. Therefore, the polycarbonate-based polyurethane foam, except for the case of 100% closed cell, it is preferable to have an open cell, a semi-open cell, a network structure, such cell structure is partially included in the closed cell according to the production of foam It might be. Most preferably, the use of a foamed foam having a network structure can increase the absorption, loading and discharge capacity of the cosmetic composition. The open cell, the half open cell and the foamed foam having a reticular structure can be confirmed by taking a picture by cutting a cross section.

The pore size of the polycarbonate-based polyurethane foam is 50 μm or more, 55 μm or more, 60 μm or more, 65 μm or more, 70 μm or more, 75 μm or more, 80 μm or more, 85 μm or more, 90 μm or more, 95 μm or more , 100 µm or more, 105 µm or more, or 110 µm or more, 500 µm or less, 450 µm or less, 400 µm or less, 350 µm or less, 300 µm or less, 250 µm or less, 200 µm or less, 190 µm or less, 180 µm or less , 170 µm or less, 160 µm or less, 150 µm or less, 140 µm or less, 130 µm or less, or 120 µm or less, for example, 50 to 500 µm, or 100 to 300 µm. Having the fine pore size as described above may be excellent in carrying capacity and discharge power. Since the cosmetic composition is disposed on the surface side to be discharged, it can have a fine pore size as described above for uniform discharge of the cosmetic composition. If the pore size is less than the above range, the supported amount is insufficient and the discharge capacity is lowered, so that a sufficient amount of the cosmetic composition is not discharged. When the pore size exceeds the above range, it is difficult to expect a desired uniform discharge power, and the surface of the foam may be rough, so that the feeling of use in the cosmetic extraction process may not be smooth.

In one example, the pore size of the polycarbonate-based polyurethane foam may have a smaller size than the polyurethane foam of the lower layer.

The density of the polycarbonate-based polyurethane foam is 0.05 g/cm 3 or more, 0.06 g/cm 3 or more, 0.07 g/cm 3 or more, 0.08 g/cm 3 or more, 0.09 g/cm 3 or more, 0.10 g/cm 3 or more, 0.11 g/cm 3 or more Or more, 0.12 g/cm 3 or more, 0.13 g/cm 3 or more, 0.14 g/cm 3 or more, 0.15 g/cm 3 or more, or 0.16 g/cm 3 or more, 0.25 g/cm 3 or less, 0.24 g/cm 3 or less, 0.23 g/cm 3 or less , 0.22 g/cm 3 or less, 0.21 g/cm 3 or less, 0.20 g/cm 3 or less, 0.19 g/cm 3 or less, 0.18 g/cm 3 or less, or 0.17 g/cm 3 or less, for example, 0.05 to 0.25 g/cm 3, Or 0.1 to 0.2 g/cm 3. If the density is less than the above range, the cosmetic composition may be discharged in an excessive amount to deteriorate usability, and when the density is above the above range, filling of the cosmetic composition may be difficult due to insufficient pores in which the cosmetic composition may be impregnated. The composition may not be discharged well.

In one example, the density of the polycarbonate-based polyurethane foam may be greater than that of the polyurethane foam of the lower layer.

The number of pores of the polycarbonate-based polyurethane foam is 80 ppi or more, 85 ppi or more, 90 ppi or more, 95 ppi or more, 100 ppi or more, 105 ppi or more, 110 ppi or more, 115 ppi or more, or 120 ppi or more, 170 ppi or less, 165 ppi or less, 160 ppi or less, 155 ppi or less, 150 ppi or less, 145 ppi or less, 140 ppi or less, 135 ppi or less, or 130 ppi or less, for example, 80 to 170 ppi or 110 to 150 ppi Can be If the number of pores of the foam is less than the above, the elasticity of the foam is poor and it is difficult to control the fluidity of the cosmetic composition, and when the number of pores exceeds the above range, durability may be deteriorated when used.

In one example, the number of pores of the polycarbonate-based polyurethane foam may be greater than the polyurethane foam of the lower layer.

The hardness of the polycarbonate-based polyurethane foam is 50 or more, 55 or more, 60 or more, 61 or more, 62 or more, 63 or more, 64 or more, 65 or more, 66 on the basis of the type F of the ASKER hardness tester. Or more, 67 or more, 68 or more, 69 or more, or 70 or more, and 90 or less, 89 or less, 88 or less, 87 or less, 86 or less, or 85 or less, for example, may have a hardness of 50 to 90. If the hardness is less than the above range, the cosmetic composition impregnated in the polyurethane foam may be excessively discharged when the cosmetic composition is taken out. If the hardness is too hard beyond the above range, the cosmetic composition may not be easily discharged.

The polycarbonate-based polyurethane foam may be a wet polycarbonate-based polyurethane foam prepared by wet foaming.

In one example, the wet method of manufacturing a polyurethane foam by foaming with wet blends and mixes the raw materials that are the material of the polyurethane foam, forms a foam block by foaming the mixture, and impregnates the foam block And quenching. The impregnation reticulation may include impregnating a foam block in a container filled with a liquid (chemical), and then reticulating by chemical action.

Polyurethane foam reticular by the wet process exhibits soft characteristics, and since fine pores can be formed, the cosmetic composition can be uniformly discharged.

In general, wet polyurethane foam produced by a wet process generally exhibits a tendency to be low in durability, chemical resistance, and chemical resistance, and thus, when carrying a cosmetic composition for a long period of time, there is a risk of deformation or damage, and physical damage caused by repeated take-out of the cosmetic composition There is a risk of deformation or damage. Since the carrier according to the embodiment of the present invention uses a polycarbonate-based polyurethane foam on the top layer, it has excellent chemical resistance, chemical resistance, and excellent physical durability, and can provide a carrier that can be used for a long time without being deformed or damaged while being soft with fine pores. have.

The laminate may include one or more polyurethane foams at the bottom of the top layer, hereinafter referred to as the bottom layer. The polyurethane foam 120 in the schematic diagram of FIG. 1 and the polyurethane foam 220 in the schematic diagrams of FIGS. 2 to 4 correspond to this.

The lower layer may include a polyether-based polyurethane foam. The lower layer stably supports the cosmetic composition, and can provide excellent elasticity to the entire carrier. In addition, when the cosmetic composition is filled from the bottom, it can exhibit excellent filling ability, and is excellent in absorbency and loading ability to absorb and maintain a sufficient amount of the cosmetic composition. Polyether-based polyurethane foam is an impregnating material, which is advantageous in terms of absorbency, carrying capacity, and discharging ability, and has a large pore size compared to polyester-based polyurethane foam, providing high air permeability, excellent fluffy feel and softness, flexibility and It is not only good in elasticity, but also excellent in durability, so it does not exhibit the phenomenon of breaking and tearing even in environments with high temperature or high temperature.

Polyether-based polyurethane foams have higher compatibility with water-in-oil cosmetic compositions than polyester-based polyurethane foams, and polyether-based polyurethane foams have excellent absorption for water-in-oil cosmetic compositions, so cosmetic compositions do not evaporate easily. , Absorbency, holding ability, and durability may be significantly superior to that of the polyester-based polyurethane foam.

The cosmetic composition is impregnated into the pores of the carrier and discharged by external force. In this case, if the cell structure of the foamed foam is closed cell, impregnation and discharge of the cosmetic composition cannot be made. Therefore, the polyether-based polyurethane foam is excluded from the case of 100% closed cells, and preferably has an open cell, a semi-open cell, a network structure, and such a cell structure includes some closed cells according to the manufacture of a foam. It might be. Most preferably, the use of a foamed foam having a network structure can increase the absorption, loading and discharge capacity of the cosmetic composition.

The pore size of the polyether-based polyurethane foam is 200 µm or more, 250 µm or more, 300 µm or more, 310 µm or more, 320 µm or more, 330 µm or more, 340 µm or more, 350 µm or more, 360 µm or more, 370 µm or more , 380 µm or more, 390 µm or more, 400 µm or more, 410 µm or more, 420 µm or more, 430 µm or more, 440 µm or more, or 450 µm or more, 800 µm or less, 750 µm or less, 700 µm or less, 650 µm or less , 600 μm or less, 590 μm or less, 580 μm or less, 570 μm or less, 560 μm or less, 550 μm or less, 540 μm or less, 530 μm or less, 520 μm or less, 510 μm or less, 500 μm or less, 490 μm or less, 480 It may be µm or less, 470 µm or less, or 460 µm or less, for example, 200 to 800 µm, or 300 to 600 µm. If the pore size is less than the above range, the holding power is poor, and if it is more than the above range, it is difficult to stably support the cosmetic composition for a long time.

In one example, the polyether-based polyurethane foam may have a larger pore size than the top layer. Through the differentiation of the pore size, while the cosmetic composition is stably supported in a sufficient amount in the lower layer, the cosmetic composition in the uppermost layer can be discharged in a uniform and appropriate amount.

The density of the polyether-based polyurethane foam is 0.015 g/cm 3 or more, 0.020 g/cm 3 or more, or 0.025 g/cm 3 or more, 0.05 g/cm 3 or less, 0.045 g/cm 3 or less, 0.040 g/cm 3 or less, or 0.035 g/cm 3 or less, for example, 0.01 to 0.05 g/cm 3, or 0.02 to 0.04 g/cm 3. When the density is less than the above range, it is difficult to stably support the cosmetic composition, and when the density is above the above range, filling of the cosmetic composition may not be easily achieved.

In one example, the polyether-based polyurethane foam may have a lower density than the top layer. Due to the difference in density, filling of the cosmetic composition is easily performed in the lower layer, and the cosmetic composition is stably supported in a sufficient amount, and the discharge amount of the cosmetic composition can be appropriately adjusted in the uppermost layer.

The number of pores of the polyether-based polyurethane foam is 40 ppi or more, 45 ppi or more, 50 ppi or more, 55 ppi or more, 60 ppi or more, 65 ppi or more, 70 ppi or more, or 75 ppi or more, 120 ppi or less, 115 ppi Or less, 110 ppi or less, 105 ppi or less, 100 ppi or less, 95 ppi or less, 90 ppi or less, 85 ppi or less, or 80 ppi or less, for example, 40 to 120 ppi or 60 to 100 ppi. If the number of pores of the foam is less than the above, the elasticity of the foam is poor and it is difficult to control the fluidity of the cosmetic composition, and when the number of pores exceeds the above range, durability may be deteriorated when used.

In one example, the polyether-based polyurethane foam may have a smaller number of pores than the top layer. Due to the multi-layered structure having the difference in the number of pores, the lower layer stably supports the cosmetic composition in a sufficient amount, imparting appropriate elasticity to the carrier, and controlling the discharge amount of the cosmetic composition in the uppermost layer is appropriate.

The hardness of the polyether-based polyurethane foam is 50 or more, 55 or more, 60 or more, 61 or more, 62 or more, 63 or more, 64 or more, 65 or more, 66 on the basis of the Type F of the ASKER hardness tester. Above, 67 above, 68 above, 69 above, 70 above, 71 above, 72 above or 73 above, 90 below, 89 below, 88 below, 87 below, 86 below, 85 below, 84 below, 83 below, 82 below , 81 or less, 80 or less, 79 or less, 78 or less, or 77 or less, and for example, may have a hardness of 50 to 90. If the hardness is less than the above range, the cosmetic composition impregnated in the polyurethane foam may be excessively discharged when the cosmetic composition is taken out. If the hardness is too hard beyond the above range, the cosmetic composition may not be easily discharged.

The polyether-based polyurethane foam may be a dry polyether-based polyurethane foam produced by dry foaming.

In one example, the dry method of manufacturing a polyurethane foam by foaming with the dry blends and mixes the raw materials that are the material of the polyurethane foam, foams the mixture to form a foam block, and gases the foam block It may include reticular injection by injecting gas in a gas chamber.

Polyether-based polyurethane foams meshed by a dry process have a larger pore size than wet meshes. In addition, the surface properties of the dry polyether-based polyurethane foam exhibit lipophilic properties.

In one embodiment, the dry method and the wet method may include the following process.

1. Preparation of raw materials and setting of raw materials

This is a process of preparing the necessary raw materials after setting the raw materials and formulations suitable for the characteristics of the product to be produced. In general, 10 to 40 kinds of raw materials are added depending on the characteristics of the product. This is a process that requires precision because the properties of the product are diversified due to the difference in input.

2. Mixing and discharge of set raw materials

It is a process in which the set raw materials are mixed and discharged from the mixing head as much as the amount calculated in each tank, and the precise input amount and mixing process (time) of the above-mentioned raw materials are required.

3. Foaming and aging of the discharged mixture

This is the process in which the mixture discharged from the mixing head to the tray (foaming shelf) is foamed and aged, and the discharged mixture is foamed in a block shape of the planned size through a time of about 2-3 minutes, and aged The surface of the block formed for the process (more than 3 sides) is sliced (work to peel off the hardened surface). This is a process for discharging the internal heat and gas generated by the chemical reaction in the foaming process, which takes about 18 hours, and the internal cell structure and cell-size may be deformed without a complete aging process. Because there is.

4. Reticulation of the completed foam block

The completed form through the aging process can be sold as a finished product in the form of a closed-cell/semi-open cell. Depending on the application, the open-cell can be opened through a reticulation process. cell) Products. This is the process of popping the cell surface of the foam to make only a frame and easily "delusion". In general, the reticulation method is divided into a gas blasting method and an impregnating quenching method. It is generally classified as "dry-sponge" and "wet-sponge".

4-1. The gas blasting (Zapping) method can be used in the production of dry polyurethane foams by placing the foam block in a gas chamber and injecting the gas to detonate it.

4-2. The impregnation quenching method is a process that is mainly used in the production of soft foam products by impregnating the foam block into a container filled with a liquid (chemical) and then phantomizing with a chemical action.

That is, the impregnation network method is a process of obtaining a kneaded product by kneading a mixture of a water-solidifying polyurethane, a solvent, a powder of a water-soluble inorganic salt, and a surfactant as a main component, and defoaming the kneaded product to obtain a defoamed kneaded product Process, forming a defoamed mixture to obtain a molded product, putting the molded product in water or in an aqueous solution, and then solidifying to form a coagulated product, eluting the inorganic salt from water from the coagulated product to form a coagulated product Polyurethane foam having a membrane structure is obtained in the process of elution and removal of the inorganic salt from the coagulation product and drying after removal of the elution, and the polyurethane foam having a network structure is used depending on the use of surfactant. Is obtained.

It can be regarded as a very expensive process due to the variety of liquids used by the characteristics of the foam material (polycarbonate type, formulation, etc.), and can be produced only for some very soft products.

In one embodiment, the carrier may further include a mesh structured fiber layer on the lower side of the layered portion, that is, on the back side opposite to the surface side from which the cosmetic composition is discharged. 2 is a schematic cross-sectional view of a carrier according to the present embodiment. The cosmetic composition carrier 200 according to the present embodiment includes a lamination portion including a plurality of polyurethane foams 210 and 220 and a mesh structure fiber layer 230, and a junction portion 240 indicated by hatching on the edge of the foam. Is formed can be integrally bonded to the laminated portion and the mesh structure fiber layer.

The mesh-structured fiber layer provides excellent bonding strength when bonded together with the laminated portion, thereby providing a carrier having excellent durability and chemical durability against physical contact or repeated use over time.

In one example, the mesh structured fiber layer has a sex root mesh structure that does not interfere with absorption of the cosmetic composition unlike the porous foam when the cosmetic composition is filled from the bottom while increasing the bonding strength when disposed at the bottom, the cosmetic composition of the lower layer Filling can be facilitated.

The hole size may be an average value of the longest diameter of a single hole. When the hole size is less than the above range, filling of the cosmetic material from the lower part is not easy, and when it exceeds the above range, bonding of the edge joint may not be performed or the bonding strength may be weakened.

The fiber thickness of the fiber layer of the mesh structure is at least 10 denier, at least 15 denier, at least 20 denier, at least 25 denier, at least 30 denier, at least 35 denier, at least 40 denier, at least 45 denier, at least 50 denier, at least 55 denier, in 60 Denier or more, 65 denier or more, or 70 denier or more, 200 denier or less, 190 denier or less, 180 denier or less, 170 denier or less, 160 denier or less, 150 denier or less, 140 denier or less, 130 denier or less, 120 denier or less, 110 Denier or less, 100 denier or less, 95 denier or less, 90 denier or less, 85 denier or less, 80 denier or less, or 75 denier or less, for example 10 to 200 denier, for example 20 to 100 denier.

The thickness t3 of the mesh structure fiber layer may be 0.1 mm or more, 0.15 mm or more, 0.2 mm or more, 0.25 mm or more, or 0.3 mm or more, 0.5 mm or less, 0.45 mm or less, 0.4 mm or less, or 0.35 mm or less, , For example 0.1 to 0.5 mm, specifically 0.2 to 0.4 mm.

For example, the mesh structure is described as a structure including the fiber layer 230, but is not limited thereto. The cosmetic composition carrier 200 according to the present embodiment may be in a form in which the bonding portion 240 indicated by hatching formed on the edge of the foam is compressed compared to the central portion by bonding.

5 is a schematic plan view of a cosmetic composition carrier 300 according to an embodiment of the present invention, and shows a junction 340 at an edge indicated by hatching.

In one embodiment, the bonding may be performed by ultrasonic bonding. By using the ultrasonic bonding, disadvantages associated with the use of the adhesive can be excluded, and excellent durability can be exhibited by stable bonding of the multilayer structure.

In one embodiment, the ultrasonic bonding may include remarkably excellent bonding strength, including the above-described mesh structure fiber layer.

In one embodiment, the bonding can be performed by thermal bonding. By the thermal bonding, disadvantages associated with the use of the adhesive can be excluded, and excellent durability can be exhibited by stable bonding of the multilayer structure.

In one embodiment, the thermal bonding may include the above-described mesh structure fiber layer, the bonding strength may be remarkably excellent.

The joint may be formed on the edge of the carrier, the width (Wd) of the joint is 0.05 mm or more, 0.10 mm or more, 0.15 mm or more, 0.20 mm or more, 0.25 mm or more, 0.30 mm or more, 0.35 mm or more, 0.40 mm or more , 0.45 mm or more, 0.50 mm or more, 0.55 mm or more, 0.60 mm or more, 0.65 mm or more, 0.70 mm or more, 0.75 mm or more, 0.80 mm or more, 0.85 mm or more, 0.90 mm or more, 0.95 mm or more, or 1.00 or more, 5.0 mm or less, 4.5 mm or less, 4.0 mm or less, 3.5 mm or less, 3.0 mm or less, 2.5 mm or less, 2.0 mm or less, or 1.5 mm or less, for example, 0.05 to 5 mm, or 0.1 to 3 mm have. When the width of the bonding portion is less than the above range, the bonding strength may be weak, and when the width of the bonding portion exceeds the above range, the capacity to support the cosmetic composition is small, and thus has no value as a product.

The joining portion may form a wing-like structure as exemplarily shown in FIGS. 6 and 12 on the edge by joining. When the cosmetic composition is placed in the container, and then the carrier is placed in the container to absorb and fill the cosmetic composition from the lower portion of the carrier, the gap between the container wall and the carrier is brought into close contact with the bonding portion so that the cosmetic composition that is not absorbed from the bottom is transferred to the upper portion of the carrier. It can prevent or improve overflow overflow.

Figure 4 shows the specifications of the carrier according to an embodiment of the present invention. The thickness of the foam may be a measure of the layer thickness on the basis of bonding prior to bonding. The layer structure of FIG. 4 is shown as a structure including the mesh structure fiber layer 230 to comprehensively illustrate the carrier of the embodiments of the present invention, but is not limited thereto.

In one example, if the thickness of the polycarbonate-based polyurethane foam used in the top layer is too thick, the effect of the present invention according to the multi-layer structure of the lamination part may be reduced by reducing the influence of the presence of the lower layer, and the top layer may be used for the discharge capacity of the carrier. Since the effect will be greater, it may be important to control the thickness of the top layer.

The thickness (t1) of the polycarbonate-based polyurethane foam is 0.1 mm or more, 0.2 mm or more, 0.3 mm or more, 0.4 mm or more, 0.5 mm or more, 0.6 mm or more, 0.7 mm or more, 0.8 mm or more, or 0.9 mm or more, Or 1.0 mm or more, 5.0 mm or less, 4.5 mm or less, 4.0 mm or less, 3.5 mm or less, 3.0 mm or less, 2.5 mm or less, 2.0 mm or less, or 1.5 mm or less, for example, 0.1 to 5 mm, or 0.5 To 2 mm. If the thickness is less than 0.1mm, it is difficult to expect the desired uniform discharge power, there may be a problem in durability, and if it is more than 5mm, cosmetic discharge may be difficult, and stable support and elasticity and soft feeling in the lower layer are given. The effect can be halved.

In one example, the thickness (t1) of the polycarbonate-based polyurethane foam may be thin compared to the thickness (t2) of the polyurethane foam of the lower layer.

The thickness (t2) of the polyether-based polyurethane foam is 3 mm or more, 4 mm or more, 5 mm or more, 6 mm or more, or 7 mm or more, 15 mm or less, 14 mm or less, 13 mm or less, 12 mm or less , 11 mm or less, 10 mm or less, or 9 mm or less, for example, 3 to 15 mm, or 5 to 10 mm. If the thickness is less than the above range, there is little value as a product because the capacity to carry the cosmetic composition is small, and if the thickness exceeds the above range, the container becomes thick and the portability becomes poor, and until the end, the use of the cosmetic composition is difficult. The remaining amount can remain.

In one example, the thickness (t2) of the polyurethane foam of the lower layer may be thick compared to the thickness (t1) of the top layer. Due to the thickness difference, a sufficient amount of the cosmetic composition is stably supported in the lower layer, and an appropriate elasticity and soft feeling are given to the entire carrier, and at the same time, proper discharge control of the uppermost layer is implemented to maximize the effect as a multi-layer structure.

In one example, the carrier may further include a primer layer disposed between at least one of the layers of the laminated portion and between the laminated portion and the mesh structure fiber layer.

The primer layer may include one or more of a hot melt nonwoven web, a hot melt mesh, a spray adhesive layer, an oily adhesive layer, and an aqueous adhesive layer. When a hot melt film is used, it is possible to prevent the absorption or discharge of the cosmetic composition by blocking the pores of the carrier, so a non-woven hot melt web is suitable. The material of the hot melt web may be at least one of polyester, polyethylene, and polyurethane, and the temperature to be melted may be 80°C to 120°C. If it is melted below the above range, it may affect the high temperature stability of the product in the future, and if it is above the above range, a physicochemical deformation may occur due to heat stress of the lamination part and the mesh structure fiber layer of the carrier during the hot-melting process. have. In one example, the oily adhesive may be a mixture of a urethane-based adhesive and a solvent acetic acid, and the aqueous adhesive may be a urethane-based but is not limited thereto.

The thickness of the primer layer may be 0.01 to 1.0mm. Within the above range, the interlayer bonding strength can be improved without inhibiting absorption and discharge of the cosmetic composition.

In one example, the diameter (Wt) and the total thickness (T) of the carrier may vary depending on the makeup container. The diameter (Wt) of the carrier may be 30 mm to 70 mm or 40 mm to 60 mm, and the discharge amount of the cosmetic composition impregnated within the above range may be appropriate. The total thickness (T) of the carrier may be 1 mm to 50 mm, for example, 5 mm to 30 mm, 6 mm to 29 mm, 7 mm to 28 mm, 8 mm to 27 mm, 9 mm to 26 mm, or 10 mm to 25 mm. If the thickness is less than the above range, the supported amount of the cosmetic composition may be small, and if it exceeds the above range, the discharge may be difficult without the remaining amount of the content when discharging the content during use.

In one example, the carrier may further include an incision in the interior. For example, the incision may be formed in a plane parallel to the layer of the carrier. For example, the incision may be formed in a plane perpendicular to the thickness direction of the carrier. For example, the incision may be formed parallel to the layer of the carrier to form an internal void.

In this specification, the incision may be formed by incising a part of the carrier, or may be formed by a laminated layer that is not joined, and the method of forming the incision is not limited to incision.

For example, the incision may be formed on one or more of the inside of the foam of the top layer, the inside of the foam of the bottom layer, between the plurality of foams of the top layer, between the plurality of foams of the bottom layer, or between the top layer and the bottom layer foam. Can be.

In one embodiment, the incision may be formed to a length excluding the junction (Wd) from the diameter (Wt) based on the cross-section of the carrier. The length may be represented by the diameter of the region where the incision is formed based on the cross section with reference to FIG. 3.

In one embodiment, the incision may serve to store and/or store the cosmetic composition carried by the carrier. A large amount of the cosmetic composition may be supported on the cavity of the incision. It can be more stably discharged from the carrier to the cosmetic composition including the incision. It is possible to adjust the loading amount and/or the discharge amount of the cosmetic composition in the carrier of the cosmetic composition including the incision. It may be adjusted to have a suitable cosmetic composition discharge amount within a desired range including the incision. For example, the discharge amount of the cosmetic composition including the incision may be made to be larger than in the case where there is no incision.

In one embodiment, the incision may include an air layer by a cavity.

In one embodiment, the carrier may recover more slowly when the pressure is removed after applying pressure to the carrier including the incision. In this way, the incision may affect the elasticity felt when the carrier is pressed to provide a soft cushion feeling.

The cosmetic composition carrier may be for impregnating and supporting a cosmetic composition having flowability.

In one embodiment, the cosmetic composition carrier has a viscosity of 5000 cps or more, 6000 cps or more, 7000 cps or more, 8000 cps or more, 9000 cps or more, 10000 cps or more, 11000 cps or more, 12000 cps or more, 13000 cps or more, 14000 cps or more, 15000 cps or more, 16000 cps or more Above, 17000 cps or more, 18000 cps or more, 19000 cps or more, or 20000 cps or more, 30000 cps or less, 29000 cps or less, 28000 cps or less, 27000 cps or less, 26000 cps or less, 25000 cps or less, 24000 cps or less, 23000 cps or less, 22000 cps Or less, or may be for supporting a cosmetic composition of 21000cps or less. For example, the composition may exhibit a viscosity of 5000 cps to 30000 cps, or 8000 cps to 25000 cps.

In one example, the cosmetic composition is an emulsion type composition, specifically, water-in-oil-in-water (W/O/W) type emulsion composition, water-in-oil-in-water type (O/W/O) type emulsion composition, water-in-oil (W/O) type It may be an emulsifying composition, an oil-in-water (O/W) type emulsifying composition, a dispersing composition, or specifically, an oil dispersion or water dispersion composition.

In one embodiment, the composition according to the present embodiment may be a water-in-oil (W/O) type emulsifying composition. The cosmetic composition is a water-in-oil type cosmetic that can be applied to various types of cosmetics, such as makeup primer, makeup base, skin cover, foundation, lipstick, lip gloss, liquid eyeshadow, eyebrow, liquid concealer, and liquid blusher. Can be. In one example, the cosmetic composition may be delivered to the target skin through a hand or applicator.

The water-in-oil type emulsifying composition may be prepared by any emulsifying method used in the art. In one embodiment, the emulsification may include preparing the oil phase and the water phase and mixing them. The mixing is not particularly limited, and a conventional mixer, homogenizer, homogenizer, or high pressure homogenizer used in the cosmetic manufacturing field may be used. The stirring speed at the time of mixing can be variously changed according to the device used and the composition content.

The cosmetic may further include a container for receiving a carrier impregnated with the cosmetic composition. The container may be a fact type container.

The carrier may be separable from the container, and the user may fill and use the cosmetic composition in a container in which the carrier is separated, and then use the carrier in combination. In addition, the user can also use it by replacing only the carrier.

The cosmetic may further include a carrier and a separate applicator.

In one embodiment, the container can accommodate the carrier and the applicator.

In one embodiment, the cosmetic may be used in a manner that a cosmetic composition impregnated in a carrier is applied to an application object by being buried in an applicator. In this case, when applying the cosmetic composition, the cosmetic composition does not get on the hand, so it is easy to use and hygienic.

The material and the shape of the applicator are not limited, but when the cosmetic composition is applied to the skin, lines or lighting marks must be applied smoothly, so the pores are fine, and it is preferable to have a soft and cushion feeling because it directly touches the skin. . In one example, the applicator may use a foam material. When applying the cosmetic composition to the skin with the applicator, the applicator temporarily absorbs the cosmetic composition, and may give a moist discomfort during application, and the cosmetic composition that has been exposed to the outside while temporarily absorbed by the applicator will be applied to the skin again. There is a possibility. Therefore, it is advantageous that the applicator does not excessively absorb the cosmetic composition, and a material that does not expand when the cosmetic composition is buried is preferable. In addition, the applicator requires that the cosmetic composition impregnated into the carrier is easily taken out, is easily applied to the skin, and exhibits an excellent feeling of use when applied to the skin.

[Test Example 3] Bond evaluation according to the hole size of the mesh structure fiber layer

The cosmetic composition carrier of Example 1 was prepared using a mesh structure fiber layer having a hole size of 1 mm, whereas in Comparative Example 1, a mesh structure fiber layer having a hole size of 2 mm was used. 6 shows a photograph of the cosmetic composition carrier.

As shown in FIG. 7, when the size of the mesh hole is increased to 2 mm or more, it can be confirmed that the joining area is lessened when the edge is ultrasonically joined, and the joining part is easily detached.

[Test Example 4] Filling evaluation of cosmetic composition

15 g of the cosmetic prepared in Test Example 1 was placed in a container having a thickness of 10 mm and a diameter of 54 mm, and the carrier of Comparative Example 2 was placed on the container, and the cosmetic composition was filled using a cylinder type moisture absorbing tool.

As shown in FIG. 8, when the size of the mesh hole is too small to 0.1 mm, a problem arises in that the filling of the cosmetic composition from the lower part is not performed well.

[Test Example 5] Evaluation of the appearance of the carrier carrying the cosmetic composition

Cosmetics were prepared by filling the carriers of Example 1 and Comparative Example 3 with 15 g of the cosmetic prepared in Test Example 1.

As shown in FIG. 9, in Comparative Example 3, the pores were shaded due to the large pore size, and the surface was not smooth, whereas in Example 1, the pore size was small and the shading effect was reduced to make the color of the cosmetic composition brighter and brighter. You can see it.

[Test Example 6] Sensory evaluation

As in the test example 5, the cosmetics of Example 1 and Comparative Example 3 filled with the cosmetic composition were taken out and used by 20 women 25 to 35 years old with puffs of air cell (wet polyurethane foam), and preference and take-out of appearance The average value is shown in Table 6 below by evaluating whether the feeling of soft use and the appropriateness of the discharged amount are on a 5-point scale (1 point: very bad to 5 points: very good).

	Appearance preference	Softness when taken out	Appropriate amount of discharge
Example 1	4.6	4.7	4.5
Comparative Example 3	1.8	2.4	2.9

According to the above results, it can be seen that the carrier according to the present invention exhibits an excellent effect by not only improving a bright appearance preference but also discharging a soft feeling of use and an appropriate amount of the cosmetic composition in terms of use.

[Test Example 7] Evaluation of cosmetic composition discharge pattern

Place the air cell (wet polyurethane foam) applicator (puff) on the carriers of Example 1 and Comparative Example 3 prepared by filling the cosmetic composition in Test Example 5, and utilize 1.0 kgf/ using a press machine (push-pull gauge).
