Hereinafter, the present invention will be described in detail.
The present invention provides a foam having a porous structure, which has a nonwoven fabric layer on one side or both sides.
The porous structure refers to a state having a lot of small pores inside or on the surface. The shape and the number of the pores may vary depending on the kind of the cosmetic composition, and the structure may be different depending on the shape of the foam. For example, the porous structure may have a three-dimensional network structure, an open cell shape, or the like.
The foam may be formed by foaming a specific polymer resin. In addition, porosity can be formed by putting a specific substance in it and then dissolving it or removing the substance through chemical reaction or the like. In addition, the resin may be processed into a nonwoven fabric, or the particulate resin may be sintered to form pores. However, the present invention is not particularly limited thereto, and can be produced by methods known in the art.
When the foam is formed by foaming, the foam process can be controlled to control the pore size and porosity of the foam, distribution of pores, density and the like according to the application. Generally, according to the art, foaming is possible by appropriately adjusting the amount and type of foaming agent, kind and amount of foaming gas, foaming temperature and pressure, and other additives, and such control is obvious to those skilled in the art.
In addition, the foam may have a number of pores of 5 to 2000 ppi (part per inch), a pore size of 0.01 to 5 mm, and a density of 0.01 to 0.5 g / cm 3, which can be appropriately adjusted according to the composition of the cosmetic.
The material of the foam may be a conventionally used polymer resin and is preferably a polyether ester elastomer, a polyurethane, an acrylonitrile-butadiene rubber (NBR), a styrene butadiene rubber (SBR), a natural rubber (NR) , Polyethylene, EVA (Ethylene Vinyl Acetate), silicone, latex, film type, SIS (Styrene Isoprene Styrene), SEBS (Styrene Ethylene Butylene Styrene), PVA (Polyvinyl Alcohol), silicone elastomer, nitrile, butyl, polyether and neoprene Or a material containing at least one member selected from the group consisting of For example, the material of the foam may be made of a polyether ester elastomer alone or may be a mixture of a polyetherester elastomer and a polyurethane. In addition, the polymer resin may contain additives such as an antibacterial material. Examples of the antibacterial material include urushiol, cardanol, polyol derived from castor oil, and silver nanofibers.
The polyetherester elastomer resin, which is one example of the material of the foam, includes a hard segment composed of a diol and a dicarboxylate (or dicarboxylic acid), a soft segment composed of a polyol and a dicarboxylate (or dicarboxylic acid) But is not limited thereto. Specifically, a polyetherester elastomer resin having a hard segment of butanediol and dimethyl terephthalate and a soft segment of a polyether polyol and a dimethyl terephthalate may be used as the elastomer resin, A high molecular weight polyetherester elastomer resin can be prepared by subjecting a diol and a polyol to a first ester exchange reaction (or an esterification reaction), and then polycondensing the diol and the polyol in a separate reactor. The kind of the diol and the polyol are not particularly limited, and they may be used alone or in combination of two or more. Examples of the dicarboxylate (or dicarboxylic acid) include dimethylterephthalate, terephthalic acid, dimethyl isophthalate, isophthalic acid, dimethyl naphthalate, naphthalene dicarboxylic acid, adipic acid, azelaic acid, (Butylene glycol), monoethylene glycol, diethylene glycol, propylene glycol, and neopentyl glycol, and examples of the polyol may be polytetramethylene glycol, polyethylene glycol, polypropylene glycol, and the like. .
Examples of the material of the foam include polyether-based urethane and polyester-based urethane.
The nonwoven fabric refers to a nonwoven fabric prepared by directly spinning fibers constituted by the nonwoven fabric manufacturing method, and the nonwoven fabric may be a spunbond nonwoven fabric or a melt-brown nonwoven fabric.
As an example of the nonwoven fabric, the spunbond nonwoven fabric means a nonwoven fabric manufactured by a spunbond method as a method of bonding webs. The spunbond method is a method in which a polymer for producing fibers is directly melted and sprayed and then bonded with heat or physical force to form a nonwoven fabric. The fibers are long connected during the spraying process.
The spunbond nonwoven fabric is not particularly limited and can be produced by a method known in the art. An example of a method for producing a spunbonded nonwoven fabric is as follows:
In the spinning process, the polymer is melted to have a constant viscosity in the spinner, then supplied to the filter device and radiated as a continuous filament through the spinning nozzle, and is transferred to the cooling chamber when the filament is radiated from the spinneret. The air stream flows through the filaments and the melted filaments become solidified. In the spunbond nonwoven fabric manufacturing method, the high-speed air stream is supplied in parallel to the filaments to stretch the individual filaments, so that the filament can be stretched and cooled by a single process.
Since the fibers are connected without breaking, the spunbond nonwoven fabric is excellent in tensile strength, durability and chemical resistance, and therefore, the foam having a spunbond layer on one side or both sides has durability, chemical resistance, elasticity, In terms of physical properties.
The thermoplastic polymer may be used as a raw material of the nonwoven fabric. Preferably, a polyetherester, a polyester, a polypropylene, a nylon, and a polyurethane may be used.
Antibacterial materials such as urushiol, cardanol, polyol derived from castor oil, silver nanofibers and the like may be added to the raw material of the nonwoven fabric.
The nonwoven layer positioned on one side or both sides of the foam means a layer made of a nonwoven fabric and the nonwoven layer can be bonded to one side or both sides of the foam by various methods known in the art, A meltblown nonwoven fabric manufactured by a manufacturing method can also be applied as the nonwoven fabric layer of the present invention. For example, the thermoplastic fiber having a low melting point may be melted to bond the nonwoven fabric layer to one side or both sides of the foam. The ultrasonic bonding or infrared ray applicator may be used as the mechanism used in the heat sealing method, but the present invention is not limited thereto .
The fiber diameter of the nonwoven fabric may be 0.3 to 30 탆, preferably 1 to 20 탆.
The density of the nonwoven fabric may be 0.03 to 0.4 g / m 2 , preferably 0.05 to 0.2 g / m 2 .
The foam may be used for cosmetics. The ease of carrying the cosmetics means that the cosmetics are stored and carried by the user before use, and when the user uses the cosmetics, an appropriate amount of cosmetics should be discharged and applied to the skin. At this time, the foam for supporting the cosmetic may be applied to the skin by being put on the cosmetic application port (also referred to as puff), or may be applied directly in contact with the skin without a separate applicator. That is, the foam for use in cosmetics needs to have chemical resistance, durability, filling ability, retention ability, dischargeability, and the like.
The cosmetic composition may be a cosmetic composition of water in oil in which water is dispersed in the form of an external oil. By controlling the ratio of oil to water, it is possible to control the physical properties such as viscosity, the degree of loading on the porous foam, and the degree of discharge during pressurization. However, in accordance with the viscosity of the present invention, cosmetic materials such as an underwater type, solubilized type, and oil type can be used as well as a water-in-oil type cosmetic.
The foam may also be used for cosmetic application. The ease of application of the cosmetic is intended to apply the cosmetic composition to the user's skin at the time of use, that is, another cosmetic is put on the application port to bring the applicator into contact with the skin, thereby delivering the cosmetic to the skin.
The present invention also provides a foam having a porous structure, which has a nonwoven fabric layer on one side or both sides thereof, and a cosmetic product comprising the foamed cosmetic composition.
The above-mentioned support refers to holding and holding an arbitrary substance or component.
The cosmetic composition of the present invention can be used as a makeup primer, a makeup base, a foundation, a skin cover, a lipstick, a lip gloss, a face powder, a lip liner pencil, an Ibron pencil, an eye shadow, a cheek collar, a compact powder, a twin cake, , Eye shadow, concealer, blusher, powder foundation, lotion, skin or airless formulation, and the like.
When the cosmetic composition is in a liquid phase, it tends to be difficult to carry and store when it is in a solid state. However, when a cosmetic composition containing the foam of the present invention is used, it is preferable that the liquid cosmetic composition and the cream- can do. When the cosmetic composition is in a solid phase, it can be supported on the foam to reduce instantaneous changes in properties of the solid phase due to external impacts such as heat or allergies. When the cosmetic composition is used, the foam serves to fix the contents, There are advantages to be able to.
