Description

Cosmetic composition having mixed feeling of use}

This specification describes a cosmetic composition having a complex feeling of use.

In cosmetics that apply to the skin and perform a makeup function, there is a need for a non-sticky, soft feeling during application and a matte finish that does not stick to dust or hair after makeup. In the case of cosmetics that usually exhibit a matte feeling, the dryness of the skin appears at the same time, so when pursuing a moisturizing feeling, the lack of matteness or, on the contrary, pursuing the matteness, there is a problem that the skin dries.

A global market expansion of so-called cushioned pact cosmetics, in which a flowable cosmetic composition is loaded onto a carrier and placed in a pact type container, is progressing. The cosmetic composition needs to have a low viscosity in order to be supported on the carrier and easily discharged.

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 at least a portion of the cell. “Open cell” means “closed cell” means a cell in which at least a portion of the cell is closed, and “reticulated structure” means closed cell, 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 cosmetic composition according to an embodiment of the present invention may include a combination of a specific wax and dimethicone.

The cosmetic composition according to the present embodiment includes one or more hard-type waxes of bees wax, polyethylene-based wax, ozokerite wax, and astrocaryum murumuru seed butter, and acrylate / Stearyl acrylate / dimethicone methacrylate copolymer (ACRYLATES / STEARYL ACRYLATE / DIMETHICONE METHACRYLATE COPOLYMER).

The specific wax may give a matte finish and at the same time impart a non-drying feeling to the skin. In general, when exhibiting a matte feeling, there is a problem of feeling dryness or pulling on the skin, whereas the specific wax may exhibit a unique complex feeling of use that simultaneously exhibits moisturizing and matting.

In one embodiment, the total amount of the hard type wax and the soft type wax is 0.001% by weight or more, 0.01% by weight or more, 0.1% by weight or more, 0.5% by weight or more, based on the total weight of the hard type wax and the soft type wax, 1.0% or more, 1.5% or more, 2.0% or more, 2.5% or more, 3.0% or more, 3.5% or more, 4.0% or more, 4.5% or more, 5.0% or more, 5.5% or more, Or 6.0% by weight or more, 10.0% by weight or less, 9.5% by weight or less, 9.0% by weight or less, 8.5% by weight or less, 8.0% by weight or less, 7.5% by weight or less, or 7.0% by weight or less, for example 0.001% to 10% by weight. Within the above range, the complex feeling of use of the present invention may be exhibited, and a stable formulation may be provided.

In one embodiment, the hard-type wax is 0.001 wt% or more, 0.005 wt% or more, 0.01 wt% or more, 0.05 wt% or more, 0.1 wt% or more, 0.2 wt% or more, 0.3 wt% or more, based on the total weight of the composition, 0.4 wt% or more, 0.5 wt% or more, 0.6 wt% or more, 0.7 wt% or more, 0.8 wt% or more, 0.9 wt% or more, or 1.0 wt% or more, 2.0 wt% or less, 1.9 wt% or less, 1.8 wt% Or less, 1.7 wt% or less, 1.6 wt% or less, or 1.5 wt% or less, 1.4 wt% or less, 1.3 wt% or less, 1.2 wt% or less, 1.1 wt% or less, or 1.0 wt% or less may be included, for example For example, it may include 0.001% to 2.0% by weight.

In one embodiment, the soft-type wax is 0.001 wt% or more, 0.01 wt% or more, 0.1 wt% or more, 0.5 wt% or more, 1.0 wt% or more, 1.5 wt% or more, 2.0 wt% or more, based on the total weight of the composition, 2.5% or more, 3.0% or more, 3.5% or more, 4.0% or more, 4.5% or more, 5.0% or more, 5.5% or more, or 6.0% or more, 10.0% or less, 9.5% or more Or less, 9.0 wt% or less, 8.5 wt% or less, 8.0 wt% or less, 7.5 wt% or less, or 7.0 wt% or less may be included, for example, 0.001 wt% to 10 wt%.

When using the wax, there is a problem that the formulation is possible only with a high viscosity formulation because the viscosity increases. In the case of a high-viscosity cream formulation, it is impossible to use it by impregnating a porous carrier, and when a mesh or the like is placed on top of the cream formulation, oil may come out from the top due to separation of product oil, so-called sweating. . Fig. 1 presents a photograph of a formulation with a sweating phenomenon. Regarding the quality deterioration problem due to the formulation stability problem, it was found that the cosmetic composition according to an embodiment of the present invention can be prepared as a low viscosity composition by including dimethicone.

The dimethicone may reduce the compatibility with the formulation of the wax to inhibit the viscosity synergistic effect to achieve a low viscosity. At the same time, the viscosity due to the wax is controlled, but the above-described feeling of use of the wax can be maintained, thereby achieving a low viscosity and unique complex feeling of use.

In one embodiment, the dimethicone is 0.1 wt% or more, 0.5 wt% or more, 1.0 wt% or more, 2.0 wt% or more, 3.0 wt% or more, 4.0 wt% or more, 5.0 wt% or more, 6.0 based on the total weight of the composition Above weight%, above 7.0%, above 8.0%, above 9.0%, above 10.0%, above 11.0%, above 12.0%, above 13.0%, above 14.0%, above 15.0%, 16.0 1% by weight or more, 17.0% by weight or more, 18.0% by weight or more, 19.0% by weight or more, 20.0% by weight or more, 21.0% by weight or more, 22.0% by weight or more, 23.0% by weight or more, 24.0% by weight or more, 25.0% by weight or more, 26.0 2% by weight or more, 27.0% by weight or more, 28.0% by weight or more, 29.0% by weight or more, 30.0% by weight or more, 31.0% by weight or more, or 32.0% by weight or more, 40.0% by weight or less, 39.0% by weight or less, 38.0% by weight or less , 37.0% by weight or less, 36.0% by weight or less, 35.0% by weight or less, or 34.0% by weight or less, for example, 0.1% by weight To 40% by weight. While implementing a low-viscosity formulation within the above range, it may exhibit a matt and moisturizing complex feeling of use.

In one embodiment, the composition according to the present embodiment 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, or 15000 cps or more It is above, and may be 20000 cps or less, 19000 cps or less, 18000 cps or less, 17000 cps or less, or 16000 cps or less. For example, the composition may exhibit a viscosity of 5000 cps to 20000 cps.

The composition according to the present embodiment may exhibit an overwhelmingly light feeling of use compared to a creamy, high-viscosity formulation. The low-viscosity formulation of the composition is thin and spread on the skin, and may exhibit a light and refreshing feeling of use.

In one example, the "cosmetic material" composition according to embodiments of the present invention may be provided by being impregnated inside the impregnating material, it is easy to impregnate with a uniform composition in the impregnating material within the viscosity range, it is easy to discharge from the impregnating material, When applied to the skin, it can show a refreshing feeling without stickiness. If the viscosity is less than the above range, the cosmetic composition is not uniformly impregnated throughout the impregnating material and sinks to the bottom, making it inconvenient to use, or there is a fear that the cosmetic composition leaks out of the product during storage. In addition, when the viscosity exceeds the above range, impregnation of the cosmetic composition into the impregnating material is difficult, and may indicate a sticky and heavy feeling of use when applied to the skin.

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.

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.

In one embodiment, the composition according to the present embodiment may include a water dispersion powder. The water-dispersible powder may enhance the matte feel by imparting a powdery feeling to the skin when applying the cosmetic composition to the skin.

In one example, the water dispersion powder may be at least one selected from silica, silica complex, polymethylsilsesquioxane, boron nitride, talc, mica, titanium dioxide and zinc oxide.

In one example, the water dispersion powder may have an average particle diameter of 0.1 to 10 ㎛.

In one example, the water dispersion powder is 0.01% by weight or more, 0.05% by weight or more, 0.1% by weight or more, 0.5% by weight or more, 1.0% by weight or more, 1.5% by weight or more, 2.0% by weight or more, 2.5 based on the total weight of the composition More than weight%, more than 3.0%, more than 3.5%, more than 4.0%, or more than 4.5%, 10.0% or less, 9.5% or less, 9.0% or less, 8.5% or less, 8.0% or less , 7.5 wt% or less, 7.0 wt% or less, 6.5 wt% or less, 6.0 wt% or less, 5.5 wt% or less, or 5.0 wt% or less, for example, 0.01 wt% to 10 wt% have.

The water-dispersible powder is dispersed in the water phase, which is the inner phase of the water-in-oil type composition, and when the cosmetic composition is applied to the skin, the emulsifying particles burst, and the evaporation of water in the inner phase can immediately impart a powdery and soft feeling of use.

In one example, the cosmetic composition may be delivered to the target skin through a hand or applicator.

The cosmetic composition according to the present embodiment may provide an emulsion composition in a stably dispersed state.

According to this embodiment, it is possible to provide a cosmetic composition having excellent formulation stability.

According to this embodiment, it is possible to provide a stable low-viscosity cosmetic composition that can be used by impregnating an impregnating material.

In one embodiment, the cosmetic composition may contain other components in addition to the above-described substances, within a range not impairing the main effect according to the embodiment of the present invention. Other ingredients that can be used include moisturizers, fatty acids, preservatives, pH adjusting agents, antioxidants, dyes, fragrances, stabilizers, thickeners, and the like, and can be appropriately selected by those skilled in the art. The content of the other components can be easily selected by those skilled in the art within a range that does not impair the objects and effects of the present invention, for example, 0.001% to 5% by weight, or 0.01 to 3% by weight based on the total weight of the composition. May be, but is not limited to.

For example, the humectant is erythritol, xylitol, maltitol, propylene glycol, sorbitol, polyglycerin, polyethylene glycol, 1,2-pentanediol, isopropylene glycol, amino acids, sodium lactate, sodium pyrrolidone carboxylate, x Siloglucan, quince seeds, carrageenan, pectin, met, curdlan, galactan, dermatan sulfate, glycogen, keratan sulfate, chondroitin, mucoitin sulfate, kerato sulfate, locust bean gum, succinoglycan, calonimic acid (Calonym acid), hyaluronic acid, heparin sulfate, sodium hyaluronate, collagen, mucopolysaccharides, chondroitin sulfate, dimethylpolysiloxane, methylphenylsiloxane, lactic acid bacteria or may be one or more selected from the culture supernatant of Bifidobacteria, but is not limited thereto.

For example, the fatty acid may be at least one selected from lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, and linolenic acid, but is not limited thereto.

For example, the thickener is intended to increase the feeling of use by providing an appropriate viscosity when used as a cosmetic composition, sodium alginate, xanthan rubber, aluminum silicate, quince seed extract, gum arabic, hydroxyethyl guar rubber, carboxymethyl Guar rubber, guar rubber, dextran, tragacanth rubber, cellulose, hydroxypropylcellulose, methylhydroxypropylcellulose, methylcellulose, carboxymethylcellulose, hydroxyethylcellulose, carboxyvinyl polymer, polyvinyl alcohol, polyvinyl skin It may be one or more selected from lollydon, disteadimonium hectorite, but is not limited thereto.

For example, the lipid may be one or more selected from mango butter, shea butter, cocoa seed butter, macadamia nut oil, batyl alcohol, behenyl alcohol, cetostearyl alcohol, cetyl alcohol, and stearyl alcohol. It is not limited to this.

For example, the preservative is benzoate, salicylate, sorbate, dihydroacetate, paraoxybenzoic acid ester, 2,4,4-trichloro-2-hydroxydiphenyl ether, 3,3,4- Trichlorocarbanilide, benzalkonium chloride, hinokitiol, resorcin, methylparaben, propylparaben, and the like, may be at least one selected from parabens, phenoxyethanol, octanediol, and hexanediol, but is not limited thereto.

For example, the antioxidant may be at least one selected from dibutylhydroxytoluene, butylhydroxyanisole, propyl gallate, and ascorbic acid, but is not limited thereto.

In one embodiment, the "cosmetics" composition according to one embodiment of the present invention may be provided impregnated inside the impregnating material.

Impregnated into the impregnating material, it is possible to further improve the dispersibility of the low-viscosity cosmetic composition, stability can be maintained, and long-term preservation is possible without phase separation of the formulation. In addition, it is easy to control the discharge amount of the cosmetic by discharging and using it from the porous impregnating material.

The impregnating material may be used by discharging the material supported therein to a separate applicator.

In one embodiment, the impregnating material may be a foam (or sponge) for supporting the cosmetic composition, but is not limited thereto. The foamed foam can be used as long as it can be used as a foamed material, but specific properties such as a specific material, cell structure, cell size, number of pores, density, and hardness can be selected according to properties required as an impregnating material.

The physical properties required as the impregnating material include, for example, absorbency, filling capacity, loading capacity, durability, and discharge capacity.

The absorbency means that the impregnating material absorbs the cosmetic composition and is uniformly supported throughout the entire 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 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.

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.

The durability 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 discharging ability 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 an appropriate discharge capacity so that an appropriate amount of the cosmetic composition can be discharged depending on the pressure applied to the impregnating material.

The properties required as the above-described impregnating material may vary depending on specific properties such as the material of the impregnating material, cell structure, cell size, number of cells, density, and hardness.

In one embodiment, the impregnating material may be a porous foam.

The material of the foam is polyethylene, polypropylene, natural rubber, polystyrene, polyurethane, acrylonitrile-butadiene rubber (NBR), synthetic sponge, urethane, foamed urethane, latex, acrylonitrile-butadiene rubber (NBR), butadiene rubber (BR), styrene-butadiene rubber (SBR), NR (Natural Rubber), chloroprene rubber (CR), isoprene-isobutylene rubber (IIR), isoprene rubber (IR), vulcanized ethylene- Propylene rubber (EPR), polysulfide rubber, silicone rubber, fluororubber, urethane rubber, acrylic rubber, EPDM (Ethylene propylene diene monomer) rubber , Polyvinyl alcohol (PVA) and ethylene vinyl acetate (EVA), NR (Nitrile Rubber), and the like.

The cell structure of the foamed foam is an open cell, a semi-open cell, a closed cell, or a reticulated structure so as to satisfy the properties required as an impregnating material. These may be formed respectively, or two or more of them may be combined.

The cosmetic composition is impregnated into the pores of the impregnating material, and discharged by the applicator. 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 impregnating material preferably has an open cell, a semi-open cell, and a network structure, except in the case of a 100% closed cell, and this cell structure may include a part of the closed cell according to the production of foam. 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 cell size of the foamed foam may be related to all of the absorbency, filling capacity, loading capacity, durability and discharge capacity of the cosmetic composition carried in the foamed foam, and is also related to the feeling of use of the foamed foam itself. The cell size of the foamed foam may be an average value measured by an optical microscope (NIKON ECLIPSE 80i). The cell size can have a level sufficient to demonstrate the intended effect of the invention. For example, the cell size may be 200 μm to 600 μm, specifically 300 μm to 500 μm. If the cell size is less than the above range, even if the carrying capacity is high, it may not be easy to discharge the cosmetic composition, and if it exceeds the above range, the carrying capacity of the cosmetic composition is lowered and the discharge amount may be too high, and the surface of the foamed foam is rough. It may lose, so it may not feel smooth when discharged to the applicator.

The density of the foam can be related to how much the cosmetic composition can be absorbed and supported inside the foam and whether it can be discharged. For example, the density may be 1.0 to 3.0 pcf (pounds per cubic feet), specifically, 1.0 to 2.0 pcf. When the density of the foam is less than 1.0, the cosmetic composition may be exposed to too much and thus the usability may be deteriorated. If the density exceeds 3.0, it may be difficult to effectively impregnate the cosmetic composition due to lack of pores in which the cosmetic composition can be impregnated. .

The number of pores of the foamed foam is related to the number of cells and is related to the physical properties of the impregnating material itself, that is, ductility, elasticity, flexibility, soft feeling, and fluffy feeling. The number of pores refers to the number of pores per square inch (ppi) of the foam, for example, the number of pores may be 40 to 120 ppi, more preferably 60 to 90 ppi have. If the number of pores of the foam is less than 40 ppi, the elasticity of the foam is poor, it is difficult to control the fluidity of the cosmetic composition, and when the number of pores exceeds 120 ppi, durability may decrease when used.

The hardness of the foamed foam is a hardness measured by an asker (manufacturer) durometer hardness meter (type F), and refers to the hardness before the composition is supported on the foamed foam. The hardness is a parameter related to the discharging ability of the cosmetic composition supported in the foam, and when the hardness is too high or too low, discharge may be excessively or too little. For example, the hardness may have a hardness of 50 to 90 based on the F type (AS F) of the ASKER hardness tester. If the hardness is less than 50, the cosmetic composition impregnated in the polyurethane foam may be excessively discharged when the cosmetic composition is taken out using the applicator. If the hardness is too hard to exceed 90, the cosmetic composition may not be easily discharged. have.

In one embodiment, the foamed foam may include a coated foam or a flocked foam. The film-forming foam is coated with a polymer foam such as rubber, polyvinyl or polyurethane, and the cell is generally smaller in size than the foam before coating. The flock processing foam may be a fiber attached to the polymer foam. The fiber may be at least one selected from the group consisting of cotton, acrylic, polyamide, nylon, polyester, silk, and rayon. Specifically, cotton, acrylic, polyamide, nylon, polyester, silk, cotton and acrylic, cotton and Rayon, nylon and polyester, and cotton, acrylic and polyester.

The diameter and thickness of the foam can vary depending on the makeup container. The foam foam may have a diameter of 30 mm to 60 mm or 40 mm to 50 mm, and the discharge amount of the impregnated cosmetic composition within the above range may be appropriate. The foam may have a thickness of 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 embodiment of the present invention, it is possible to provide a cosmetic composition comprising the above-described cosmetic composition according to an embodiment of the present invention and an impregnating material impregnated with the cosmetic composition.

The cosmetic may further include a container for storing an impregnating material impregnated with the cosmetic composition. The container may be a fact type container.

The foamed foam may be detachable from the container, and the user may fill and use the cosmetic composition in a container from which the foamed foam is separated, and then use the foamed foam. In addition, the user can use it by replacing only the foam.

The cosmetics may further include an impregnating material and a separate applicator.

In one embodiment, the container may contain the impregnating material and the applicator.

In one embodiment, the cosmetic may be used in a manner that a cosmetic composition impregnated with an impregnating material 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 need to 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 upon application, and the cosmetic composition that has been exposed to the outside while temporarily absorbed by the applicator may 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 with the impregnating material is easily taken out, easily applied to the skin, and exhibits an excellent feeling of use when applied to the skin.

In one embodiment, the applicator is acrylonitrile-butadiene rubber (NBR), styrene-butadiene rubber (SBR), natural rubber (NR), polyvinyl chloride, polyethylene, ethylene-vinyl acetate butyl rubber (EVA), latex, silicone, Styrene-isoprene-styrene (SIS), styrene-ethylene-butylene-styrene (SEBS), polyvinyl alcohol (PVA), nitrile rubber, butyl rubber, chloroprene rubber (neoprene®, polyolefin, polyurethane, and ether based polyurethanes) It may be a foam made of one or more selected from the group consisting of a mixture of and ester-based polyurethane, for example, acrylonitrile butadiene rubber or styrene-butadiene rubber.

Hereinafter, the present invention will be described in detail with reference to Examples, Comparative Examples and Test Examples. These are only provided by way of example to explain the present invention in more detail, the scope of the present invention is not limited by these examples, comparative examples and test examples for those skilled in the art It will be self-evident.

[Test Example 1] Preparation of water-in-oil type emulsion cosmetic composition

Water-in-oil emulsified cosmetic compositions of Examples and Comparative Examples were prepared with the compositions of Tables 1 and 2 below.

[Test Example 2] Viscosity evaluation

After storing the compositions of the Examples and Comparative Examples at 30 ° C. for 8 hours, the viscosity at 1 minute at 64 rpm and 12 rpm was read using a Brookfield Viscometer Model DV-II +. The results are shown in Tables 1 and 2.

From the above results, it can be seen that, in the case of the example composition, a low-viscosity composition is achieved, whereas in Comparative Example 1-3 using cetylethylhexanoate instead of dimethicone, it is formulated with a high viscosity due to wax. In addition, even when using dimethicone as in Comparative Example 4, it was difficult to obtain a desired low-viscosity formulation when only hard-type wax was used as the wax. Furthermore, it was confirmed that even when non-polar polybutenes such as dimethicone were used instead of dimethicone (Comparative Example 6), the viscosity was significantly increased due to good compatibility with wax.

[ Test example  3] Cosmetic  Sensory evaluation of the composition

The water-in-oil type emulsifying compositions of Examples and Comparative Examples prepared above were used for 10 female panels aged 25 to 35 years, and evaluated for feeling of use. Specifically, whether it is applied freshly without stickiness when applied (freshness), whether it feels matt and powdery when applied (matte), or whether it remains moist and soft without pulling or drying on the skin (moisturizing feeling) The average value is shown in Table 3 by evaluating on a 5-point scale (1 point: not at all-5 points: very so).

Item Example 1 Comparative Example 1 Comparative Example 2 Comparative Example 3 Comparative Example 4 Comparative Example 5 Comparative Example 6 Neatness 5 One 0 One One One 0 Matte 5 3 One 3 3 One 0 Moisturizing 4 3 5 4 4 5 3

In the case of the example, it can be confirmed that it is applied to the skin neatly during application, and after application, it gives a moisturizing feeling to the skin while showing a matte and powdery feeling. Comparative Example 1-3 without using dimethicone In case of and 6, because of the high viscosity, it was difficult to apply freshly, resulting in poor usability, and in the case of Comparative Examples 1 and 2 using only one type of wax, too light or too heavy to achieve freshness and mat. In addition, even when using dimethicone, Comparative Examples 4 and 5 using only one wax had a remarkable lack of refreshing, especially in Comparative Example 5 using only soft type wax, the matteness was remarkably insufficient.

[Test Example 4] Preparation of cosmetics supported on impregnating materials

Cosmetics were prepared by impregnating the foamed foam with the water-in-oil emulsifying compositions of Example 1 and Comparative Example 3 prepared above. As a foamed foam, it is a dry polyether-based urethane foam material, the number of pores is 60 ppi, the density is 1.8 lb / ft ³ , and the hardness is 70 (based on the ASKER hardness tester F type), and the cell size ( cell size) 350㎛, diameter 48mm, thickness 10mm was used.

Fig. 2 shows a picture of the cosmetics impregnated. In the case of Example 1 (right), it was stably supported on the impregnating material and maintained in a uniformly absorbed state without phase separation. In the case of Comparative Example 3 (left) of high viscosity, the impregnating material (upper left) could not be impregnated into the container. It can be confirmed that the composition overflowed (lower left).
