UV light emitted from sunlight is a major cause of erythema, edema, freckles, and skin cancer in the skin. Recently, many studies on various skin diseases caused by ultraviolet rays are actively conducted.

Generally, ultraviolet rays are classified into UV-C at a wavelength of 240-280 nm, UV-B at a wavelength of 280-320 nm, and UV-A at a wavelength of 320-400 nm according to the wavelength. UV-C passes through the ozone layer and disappears without reaching the surface. UV-B penetrates into the epidermis of the skin, causing erythema, freckles and edema. UV-A penetrates the skin's dermis and is known to promote skin aging and skin irritation by promoting skin cancer, wrinkles and melanin formation.

The general public's interest in the sun protection product market has increased significantly and as a result, there are a variety of sunscreen products with SPF (sun protection factor) on the market. The type of ultraviolet screening product is generally made of cream or lotion and classified into water in oil (W / O) and oil in water (O / W) depending on the composition of internal and external contours of emulsion. .

Until now, ultraviolet screening products have been shown to be mainly used in the summer season. However, recently, there has been an increase in demand for the use of four seasons as well as in summer due to changes in lifestyle due to an increase in the population enjoying leisure activities and awareness of the harmfulness of ultraviolet rays have. As a result, there is an increasing trend of consumers demanding products that have improved usability and convenience.

In general, sunscreen products are made into a water-in-oil type that externally tops the oil to improve water resistance to sweat and water. In the case of an underwater type sunscreen product, the feeling of use when applied to skin is neat as compared to a water-in-oil type product, but the drawback is that it is still easily washed off with sweat or water despite continuing research to improve water resistance And the persistence of the ultraviolet shielding effect, which is a conventional object of the ultraviolet screening product, is remarkably deteriorated.

For example, Korean Patent Registration No. 10-1002866 discloses an ultraviolet screening cosmetic composition in the form of a water-in-oil type emulsion. More specifically, it relates to an ultraviolet screening cosmetic composition containing an aqueous component and an organic gelling agent And is in the form of a solid water-in-oil type emulsion, and is characterized by containing an aqueous phase component, an organic gelling agent, an organic ultraviolet screening agent, an inorganic ultraviolet screening agent, a wax, a surfactant, an oil and a pigment.

The above-mentioned prior art has a high SPF value and a PA value and thus has an excellent ultraviolet ray shielding effect. When the prior art products are used, the skin is not dried because of the excellent sensation of coolness and moistness due to the water component, This has an excellent effect.

However, the above-mentioned prior art has a disadvantage that it is more persistent than an underwater type ultraviolet screening product, but has a feeling of heavy feeling and stickiness. This is not related to the ultraviolet screening product of the water-in-oil type. In the case of a water-in-oil type ultraviolet screening product, the ratio of the internal phase water phase is raised to lightly adjust the feeling of use, so that the product is manufactured at a high viscosity.

In addition, in general, a water-in-oil type product is known to have poor emulsification stability as compared with an underwater type product. In the prior art, the stability of the product deteriorates due to the separation of the water phase from the inner water phase and the traumatic oil phase during long- There is a problem. Therefore, the viscosity is increased to increase the stability, and when the viscosity is increased, the feeling of use is heavy and sticky.

As a study similar to the present invention, UV-screening products of the water-in-oil type have been adjusted to the viscosity and the usability has been improved so that the ultraviolet screening products of the water-in-water type have been packed in the tubes or pump containers. However, Inconvenience occurs.

In addition, particularly in the case of summer, a feeling of cold which reduces the heat of the skin is more preferred. However, when the product of the above formulation is applied to the skin, It is buried in the hands, and it is troublesome to wash the hands again to prevent contamination and stickiness.

In order to solve such a problem, Korean Patent Registration Nos. 10-1257628 and 10-1355051 disclose a proposed technique in which a UV-screening agent of a water-in-oil type is applied to a foamed urethane foam of ether polymer or ester polymer type The present invention relates to a cosmetic product impregnated with a foamed urethane foam.

The foamed urethane foam is a polymer having a urethane bond (-NH-COO-) in a polymer chain, and is produced by bonding an isocyanate having a valence of two or more with an active hydrogen compound such as a polyol. The polyol is selected from a polyether polyol or a polyester polyol.

However, the foamed urethane foam using the polyether polyol or the polyester polyol proceeds together with the exothermic reaction, and polyurethane is foamed while generating heat and high-pressure gas. At this time, in the portion where the foamed thickness is thinly formed, And the pressure is applied, the polyurethane gradually inflates and deforms on the inner surface.

Also, the isocyanate is an aromatic isocyanate such as tolulene diisocyanate (MDI) or methylenediphenyl diisocyanate (MDI), which has a quinone imide structure due to ultraviolet rays, resulting in yellowing of the foamed urethane foam.

When the foamed urethane foam containing the polyester polyol is impregnated with the ultraviolet barrier cosmetic composition, the foam is gradually hardened over time and the surface is cracked and a part of the foam is broken.

In addition, amine is used as a catalyst in the production of foamed urethane foam. The amine is mostly volatilized by heat during the production of the foamed urethane foam, but there is a problem that the amine remains unpleasant to some people with sensitive smell.

Disclosure of Invention Technical Problem [8] Accordingly, the present invention has been made to solve the above problems, and an object of the present invention is to provide a cosmetic composition in which a low viscosity ultraviolet ray blocking composition of W / O is packaged in a compact type container.

In addition, the present invention solves the problem of yellowing and deformation of the inner urethane foam caused by the foamed urethane foam by impregnating the foamed NBR foam with a low-viscosity water-in-oil type UV blocking cosmetic composition instead of impregnating the conventional foamed urethane foam. The purpose is to do.

In addition, the present invention relates to a cosmetic composition containing a low-viscosity, water-in-oil type ultraviolet barrier cosmetic composition impregnated with a foamed NBR (nitrile butadiene rubber) foam and packaged in a compact type container, To provide a barrier cosmetic composition.

It is another object of the present invention to provide an ultraviolet screening product having a good ultraviolet screening effect and being easy to use and carry.

In addition, the foamed NBR (nitrile butadiene rubber) foam of the present invention is characterized by having a hardness of 15 to 35 on the basis of ASKER hardness F type (Type F) before impregnating the contents.

In addition, the foamed NBR (nitrile butadiene rubber) foam of the present invention has a density of 180 to 240 g / L before impregnating the contents.

FIG. 1 is a perspective view of a foamed NBR (nitrile butadiene rubber) foam according to an embodiment of the present invention, FIG. 2 is a perspective view of a foamed NBR (nitrile butadiene rubber) foam according to another embodiment of the present invention, FIG. 4 is a perspective view of a foamed NBR (nitrile butadiene rubber) foam according to another embodiment of the present invention. FIG. 4 is a perspective view of a foamed NBR (nitrile butadiene rubber) foam according to another embodiment of the present invention.

The present invention relates to a compact type (10), comprising a foamed NBR (nitrile butadiene rubber) foam (10) impregnated with a low viscosity water-in-oil type emulsion ultraviolet screening composition containing an oily component, an emulsifier, an organic or inorganic ultraviolet screening agent, It is a formulation.

The oily components used in the present invention include vegetable oils such as rosehip oil, safflower oil, peach seed oil, methoform seed oil and sunflower seed oil, dicaprylyl carbonate, squalane, neopentylglycol diheptanoate, Acetate, trioctanoin, C12-15 alkyl benzoate, C12-15 alkyl ethyl hexanoate, octyldodecyl myristate, tricaprylyl, octyldodecylstearoyl stearate, bis-hydroxyethoxypropyldimetate Chitosan, chicone, caprylic, capric triglyceride, isotridecylisononanoate, polyglyceryl-2 triisostearate, diisostearyl malate, dipentaerythritol pentaerythritide, cetyl octanoate, And synthetic esters or hydrocarbons such as carboxymethylcellulose, carboxymethylcellulose and carbitol, silicone oils such as phenyltrimethicone, cyclomethicone, dimethicone, decamethylcyclopentasiloxane and the like Up to more than one selected species, it is contained in an amount of 20 to 80% by weight relative to the total weight of the composition. If the oily component is less than 20% by weight, the stability of the composition is poor or the viscosity is too high, and the feeling of use is heavy and tacky, and the usability is poor. When the content is more than 80% by weight, the stability is poor.

As the emulsifier used in the present invention, a non-ionic surfactant having an HLB range of 1 to 6 and a low HLB is suitable for producing a water-in-oil type emulsion, and specifically, cyclopentasiloxane and PEG / PPG-18/18 dimethicone Cyclopentasiloxane and PEG / PPG-18/18 Dimethicone, Glycol Stearate, Sorbitan Sesquioleate, Glyceryl Oleate, Glycol Distearate, Propylene Glycol Propylene glycol monostearate, glyceryl stearate, sorbitan stearate, PEG-30 dipolyhydroxystearate, PEG-10 dimethicone (PEG- -10 Dimethicone), cyclopentasiloxane / PEG.PPG-19.19 dimethicone, sorbitan isostearate, lauryl PEG.PPG-18. (PEG-PPG-18.18 methicone), cetyl PEG.PPG-10.1 dimethicone, lauryl PEG-9 polydimethylsiloxyethyl dimethicone (Lauryl PEG- ), And it is contained in an amount of 0.01 to 10% by weight based on the total weight of the composition. When the amount of the emulsifier is less than 0.01% by weight, the emulsion is not formed or the stability of the composition is poor. When the amount of the emulsifier is more than 10% by weight, stickiness of the emulsifier itself and inherent odor are generated.

The ultraviolet screening agent used in the present invention may be used either individually or in combination with an organic ultraviolet screening agent or an inorganic ultraviolet screening agent. Specific examples of the organic ultraviolet screening agent include octyl methoxycinnamate, octyl salicylate, octocrylene, butyl methoxydibenzoylmethane, oxybenzone, octyltriazone, menthyl anthranilate, 3,4-methyl benzylidene kempfer, Isoamyl-P-methoxy cinnamate, bisethylhexyloxyphenol methoxyphenyltriazine, and methylenebisbenzotriazolyltetramethylbutylphenol. As the inorganic ultraviolet blocking agent, titanium dioxide having an average particle size of 5 to 100 nm , Zinc oxide having an average particle size of 5 to 300 nm, iron oxide having an average particle size of 5 to 300 nm, or the like can be used. At this time, the larger the average particle size of the inorganic sunscreen agent, the more the whitening phenomenon is applied to the skin, thereby decreasing the value of the product. On the other hand, when the particle size is too small, the skin penetrates into the skin to cause irritation. Is suitably 300 nm or less, and 10 to 50 nm is suitable when both skin irritation and cloudiness are considered at the same time.

In addition, the ultraviolet screening agent is contained in an amount of 1 to 35% by weight based on the total weight of the composition. When the ultraviolet screening agent is less than 1% by weight, the ultraviolet screening effect is insignificant to 10 (SPF index) or less. When the ultraviolet screening agent is more than 35% by weight, the whitening phenomenon and shine are worse.

The pigment used in the present invention may be at least one selected from the group consisting of PMMA (polymethylmethacrylate), silica, nylon, nitrile butadiene rubber (NBR), ultramarine, iron oxide, Mica, talc, cerasite and boron nitride can be mixed and used in an amount of 0.1 to 20% by weight based on the total weight of the composition. If the content of the pigment is less than 0.1% by weight, the effects such as adhesion, color, and agglomeration are insignificant. If the content is more than 20% by weight, the viscosity is excessively increased and the feeling of use becomes stiff and the stability of emulsification is deteriorated .

The water component used in the present invention is at least one selected from the group consisting of purified water, propylene glycol, 1,3-butylene glycol and glycerin, and is contained in an amount of 30 to 70% by weight based on the total weight of the composition. When the water phase component is less than 30% by weight, the viscosity is too low to lower the stability of the formulation. When the water phase component is more than 70% by weight, the viscosity becomes too high.

In addition to the above components, at least one selected from preservatives, fragrances and other additives may be further added to the ultraviolet screening composition. Particularly, parabens such as methylparaben, propylparaben, butylparaben, ethylparaben and the like which can be used as a preservative can be mixed into an oil phase, and in case of phenoxyethanol, they can be mixed with an aqueous phase.

In addition, the fragrance is added to the oil phase of the water-in-oil type at the final stage of the process for producing the composition.

The water-in-oil UV blocking cosmetic composition of the present invention has a low viscosity in the range of 5,000 to 15,000 cps. If the viscosity of the water-in-oil type ultraviolet barrier cosmetic composition is less than 5000 cps, separation of oil phase and water phase occurs immediately after preparation of the emulsion, so that it is difficult to impregnate into the NBR (nitrile butadiene rubber) foam 10 with a uniform composition. When the viscosity is more than 15000 cps There is a problem that the value as a product is deteriorated due to the sticky and heavy use feeling on the skin.

The UV-blocking cosmetic composition of the present invention is packed in a compact type container using a foamed NBR (nitrile butadiene rubber) foam 10. This is because the compact type container is excellent in portability compared to a tube or pump type container in terms of portability and ease of making, but in the case of a flowable cosmetic, it is likely to overflow or contaminate the container, 1, the ultraviolet barrier cosmetic composition is impregnated into a foamed NBR (Nitride Butadiene Rubber) foam 10 and embedded in a compact type container, as shown in FIG.

According to another embodiment, as shown in FIG. 2 to FIG. 3, the ultraviolet barrier cosmetic composition is impregnated with a foamed NBR (nitrile butadiene rubber) foam 10 having an impregnated hole 20, and is embedded in a compact type container .

As shown in FIG. 4, the foamed NBR (nitrile butadiene rubber) foam 10 may be formed such that the impregnated holes 20 are formed in a non-aligned manner.

The foamed NBR (nitrile butadiene rubber) foam 10 impregnated with the ultraviolet barrier cosmetic composition of the present invention can not impregnate the ultraviolet ray blocking cosmetic composition because the bubble is trapped in NBR (nitrile butadiene rubber) in the case of a closed cell An open cell shape is preferred.

In addition, the foamed NBR (nitrile butadiene rubber) foam 10 used in the present invention should be a proper NBR (nitrile butadiene rubber) foam 10, and it is suitably an open cell type foamed NBR nitrile butadiene rubber foam having a hardness of from 15 to 35 and a density of from 180 to 240 g / L in terms of DUROMETER HARDNESS measuring instrument type F (Type F) on the basis of ASKER NBR (nitrile butadiene rubber) foam 10 may be used.

If the hardness of the foamed foam 10 is less than 15 and the density of the foamed foam 10 is less than 180 g / L, the foamed foam 10 is too soft to impregnate the UV-blocking cosmetic material in a uniform distribution, There is a problem in that the water-in-oil type ultraviolet barrier cosmetic impregnated in a foamed NBR (nitrile butadiene rubber) foam 10 is excessively discharged when a tool or a hand is put on the makeup. When the hardness is more than 35 and the density is more than 240 g / L, There is a problem that the foam is hard and the ultraviolet blocking cosmetic material in the water-in-oil type can not easily be discharged.

In addition, the foamed NBR (nitrile butadiene rubber) foam 10 of the present invention includes at least one foamed foam having a pore number of 10 to 150 ppi (pore per inch). The pore number may be NBR (nitrile butadiene rubber) The number of pores per inch of the form.

If the number of pores in the foamed foam 10 is less than 10 ppi, the number of pores impregnated with the cosmetic composition will be low, resulting in poor penetration. If the foamed pore 10 has a pore number of more than 150 ppi, the pore number may be dense, . And more preferably 50 to 100 ppi.

Hereinafter, the production examples, examples and test examples of the present invention will be described in detail.
