Further, the "carrier" may be used to discharge (transfer) the material supported thereon to a separate applicator. The composition supported on the “carrier” can be delivered to the skin, for example, through a hand, a puff, a tip, a brush or the like (also referred to as an applicator or applicator).

In the present specification, "discharge ability" or "discharge power" refers to the amount of cosmetic discharged when the cosmetic is taken by the applicator from a support body carrying a cosmetic (cosmetic composition), and not a large amount or a proper amount It is preferred that the cosmetic is discharged.

A supporting unit according to an embodiment of the present invention will be described with reference to FIG. 1.

The supporting unit 10 includes a supporting body 110 and a cosmetic 120.

In one embodiment, the carrier 110 is provided in a disc shape, but in other embodiments, it may be variously modified, such as a square plate shape or a long cylindrical shape.

The cosmetic 120 is in the form of oil-in-water, and is supported in the carrier 110.

The carrier 110 carries and discharges a cosmetic. The carrier 110 is not limited to this, but a sponge may be used.

Sponges are sponges made of rubber, fiber or resin. The sponge is not particularly limited, and may be a natural sponge or a synthetic sponge, and the natural sponge may be, for example, sponge sponge, natural rubber sponge, etc., and the synthetic sponge is a synthetic resin sponge, urethane, urethane foam, latex, acrylonitrile- Butadiene Rubber (NBR), Butadiene Rubber (BR), Styrene-Butadiene Rubber (SBR), Natural Rubber (NR), 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), or mixtures thereof.

The foamed urethane (foamed urethane foam), which is a kind of sponge, is not particularly limited, but as an example, polyether-based foamed urethane (based on ether polyol), polyester-based foamed urethane and polycarbonate-based foamed urethane It may be to include, specifically, the urethane foam may be to include a polyether-based urethane foam.

The polyether-based foamed urethane includes polyether-based dry foamed urethane and polyether-based wet foamed urethane, and the polyester-based foamed urethane includes polyester-based dry foamed urethane and polyester-based wet foamed urethane, and polycarbonate-based foamed The urethane may include polycarbonate-based dry foam urethane and polycarbonate-based wet foam urethane.

The sponge includes pores, and the pores included in the sponge may have an average size of 30 to 1000 μm. Specifically, the average pore size is 1000 µm or less, 900 µm or less, 800 µm or less, 700 µm or less, 600 µm or less, 500 µm or less, 400 µm or less, 300 µm or less, 200 µm or less, 100 µm or less, 50 µm It may be less than or equal to or less than 30 μm, 30 μm or more, 50 μm or more, 100 μm or more, 200 μm or more, 300 μm or more, 400 μm or more, 500 μm or more, 600 μm or more, 700 μm or more, 800 μm or more, 900 μm or more Or more or 1000 μm. Measurement of the average pore size of the sponge in the present invention can be measured by magnification to 5x / 0.15 using an optical microscope (Nikon ECLIPSE LV100POL). When the pore size of the sponge is less than 30 µm on average, the pore space for carrying the cosmetic is small, and the carrying capacity is poor, and if it exceeds the average of 1000 µm, the pore space is too large and the discharge control ability of the cosmetic may be reduced.

The carrier 110 may have a thickness of 1 mm to 50 mm. When the thickness of the support body 110 is less than 1 mm, the amount of the cosmetic material is small, and when it exceeds 50 mm, it is difficult to discharge the cosmetic material when used, without the remaining amount of its contents. The carrier 110 may have a thickness of 3 mm to 45 mm, for example, may have a thickness of 5 mm to 40 mm, for example, may have a thickness of 8 mm to 35 mm, for example 10 mm to It may have a thickness of 30 mm. Specifically, the thickness may be 50 mm or less, 40 mm or less, 30 mm or less, 20 mm or less, 10 mm or less, or 5 mm or less, and may be 1 mm or more, 10 mm or more, 20 mm or more, 30 mm or more, 40 mm or more, or 50 mm or more.

The cosmetic 120 may include a water-increasing agent, purified water, preservatives, oil, emulsifier, and fragrance.

Specifically, the cosmetic 120 is water-phase thickener 0.05 to 6% by weight or 0.05 to 2% by weight, solid powder pigment 0.1 to 30% by weight, purified water 50 to 90% by weight, preservative 0.2 to 3% by weight, oil 5 to 20 It may contain weight%, emulsifier 0.5 to 10% by weight and fragrance 0.1 to 1% by weight.

The water-increasing agent may be one or more selected from the group consisting of agar, cellulose, cellulose gum, xanthan gum, mannan, gelatin, and the like. The water-increasing agent may particularly include agar.

If the content of the water-increasing agent is too low, the cosmetic material 120 loaded on the supporting unit 10 may be physically unstable or the discharge power from the supporting unit 10 may be excessive. If the content of the water-increasing agent is too high, mixing problems may occur due to high viscosity, which may make cosmetic preparation difficult or the discharge power from the supporting unit 10 may be very low.

The oil may be one or more selected from the group consisting of ester-based, triglyceride-based, hydrocarbon-based and silicone-based oils. The oil may be blended in different proportions depending on the degree of spreadability required for cosmetics such as softness, moistness, and adhesion.

The solid powder pigment may be variously included according to the UV blocking function, covering power, color, and spreadability required by the cosmetic composition, for example, titanium dioxide, zinc oxide, polymethylsilsesquioxane, polymethyl methacrylate, talc , Alumina, iron oxide, mica, silica, alumina, organic pigments, and natural pigments.

Emulsifiers include sorbitan stearate, sorbitan laurate, sorbitan sesquioleate, polyglyceryl-3 methylglucose distearate, cetearyl alcohol, cetaaryl glucoside, behenyl alcohol, arachidyl alcohol, arachidyl glucoside, One or more selected from the group consisting of glyceryl stearate, PEG-40 stearate, PEG-100 stearate, polysorbate 20, polysorbate 60, and polysorbate 80 can be used.

As the preservative and fragrance, materials that are commonly used may be appropriately used.

The cosmetic composition 120 that is not supported on the supporting body 110 is in a solid state with little flowability at room temperature, and the hardness of the cosmetic composition 120 may be 3N to 600N or 3N to 300N at room temperature. In addition, the hardness of the supporting unit 10 may be 50g to 100g or 50g to 70g. If the hardness of the cosmetic 120 and / or the hardness of the supporting unit 10 is too high, the discharge power is low, and the problem is caused. If the hardness of the cosmetic 120 and / or the hardness of the supporting unit 10 is too low, an anomaly occurs or The discharge power may be too large.

In the supporting unit 10, the cosmetic 120 is improved in stability by the supporting body 110. In other words, although the cosmetic 120 itself generates a water phenomena and collapses when stored at an angle, the occurrence of the water phenomena is suppressed in the loading unit 10 and the shape can be maintained even when stored. This is judged because the loading unit 10 serves as a structure in the cosmetic 120 to suppress the flow of the cosmetic 120. In addition, it has an appropriate discharge power during makeup using an applicator (puff, etc.).

Specifically, the carrying unit 10 is not limited to this, and even if stored for 24 hours or more at room temperature, no phenomena occur, and the shape can be maintained even when stored at room temperature for 3 days at a 55 degree slope. The supporting unit 10 may have a discharge force of 0.01 g to 0.4 g or a discharge force of 0.1 g to 0.4 g.

In the above description, a method of measuring the properties of the cosmetic 120 and the supporting unit 10 is described in the experimental example.

For cosmetics, after dispersing the aqueous phase portion (aqueous thickening agent (agar) / purified water / pigment base / preservative) at 80 ° C or higher, for example, 80 ° C to 100 ° C, after dispersing it, 80 ° C or higher, for example, 80 ° C It can be prepared by adding an oil part (oil / emulsifier) heated to 100 ° C. to emulsify, and then adding fragrance after emulsification.

Thereafter, the cosmetic becomes a solid state with little flow at room temperature. After heating by heating to 40 ° C to 60 ° C, it is supported on the support body 110 to produce a support unit 10.

Figure 2 shows an exploded perspective view of a cosmetic device according to an embodiment of the present invention.

The cosmetic device 1 includes a supporting unit 10, an upper case 20, a lower case 30, a supporting member receiving portion 40, a cover 50, and a cosmetic tool 60. The upper case 20 and the lower case 30 form an accommodating space, and the supporting unit 10, a supporting member accommodating portion 40, a cover 50, and makeup tools (applied tools, 60) are accommodated in the accommodating space. do.

The carrier 10 is a cosmetic material 120 in the form of oil-in-water is supported on the carrier 110.

The cover 50 also accommodates the role of the seat of the makeup tool 60.

The user performs makeup while the cosmetic tool 60 is pressed and released to the supporting unit 10.

Hereinafter, the present invention will be described in detail through experimental examples.

Cosmetic  Produce

After dispersing the water phase part (water thickener / purified water / pigment base / preservative) while heating to 90 ° C, the oil part (oil / emulsifier) heated to 90 ° C was added to emulsify, and the fragrance was added after emulsification.

Agar as a water-increasing agent, purified water as a solvent, titanium dioxide, iron oxide and polymethyl methacrylate as a solid powder pigment in a weight ratio of 6: 3: 1, and phenoxyethanol and ethylnuclear glycerin in a mass ratio of 8 : 1, butylene glycol dicaprylate / dicaprate was used as an oil, and polysorbate 60 and sorbitan stearate were used as an emulsifier in a mass ratio of 2: 1.

Cosmetics 1 to 7 were prepared by changing the content of the agar used as a water-increasing agent and the content of the solvent accordingly, and the composition is shown in Table 1 below. In the case of cosmetic 6 and cosmetic 7, the viscosity was excessively high, and thus mechanical dispersion was difficult, so that cosmetic was not produced.
