Hereinafter, embodiments of the present invention will be described in detail.

First, an oil in water (O / W) type hydrogel mask composition comprising an oil portion and a water portion having an antioxidant and anti-inflammatory effect containing Ulleungdo's trilobate root extract of the present invention, 50.00% by weight of an oily phase and 50% to 99.95% by weight of a water-

The upper part of the water contains Ulleungdo trilobal root extract of 1.00 to 10.00% by weight based on the total weight,

And the refractive index difference between the oil phase portion and the water phase portion is 0.02 to 0.15.

Therefore, when the skin is sensitized by external stimuli due to the antioxidant and anti-inflammatory effect, the refractive index difference between the upper part and the upper part is reduced as the water is evaporated at the skin temperature, so that it is discolored transparently so that the best application time Can be easily confirmed with the naked eye.

Ulleungdo's three-root root extract contains a large amount of saponin, so it has excellent antioxidant and anti-inflammatory effects.

The cosmetic composition of the present invention is an oil-in-water type hydrogel mask composition in which an oily portion is dissolved in water, and has excellent moisturizing and oiliness.

In the composition of the present invention, the oily portion may be contained in an amount of 0.05 to 50.00% by weight, preferably 5 to 20% by weight based on the total weight of the composition. When the content is less than 0.05% by weight, it is difficult to realize opaque milky white , And if it is more than 50.00% by weight, the formulation stability of the oil-in-water type may be deteriorated.

The water phase may be contained in an amount of 50 to 99.95% by weight, preferably 80 to 95% by weight based on the total weight of the composition. When the weight fraction is less than 50% by weight, emulsion formation in oil- It is difficult to implement opaque milky white.

In addition, the hydrogel mask composition of the present invention has an opaque milky white color with a refractive index difference of 0.02 to 0.15 between the upper part and the upper part of the water. When applied to the skin, moisture is evaporated by the skin temperature, And the refractive index difference is reduced so as to be transparently changed.

According to an embodiment of the present invention, the refractive indexes of the oil phase portion and the water phase portion may be in the range of 1.250 to 1.450, and the refractive index difference may be 0.02 to 0.15, preferably 0.08. At this time, when the refractive index difference is less than 0.02, opaque milky white color is difficult to implement. When the refractive index difference is more than 0.15, the refractive index difference becomes too large, and it may be difficult to expect an effective transparent discoloration at the degree of moisture evaporation at skin temperature.

Therefore, the present invention has an advantage that it is easy to visually confirm the best application time according to the individual difference by having the variable transparency using the refractive index difference between the water top and the oil part.

In the composition of the present invention, the difference in the refractive index between the upper aqueous layer and the upper aqueous layer can be appropriately controlled within the above range depending on the essential components of the cosmetic composition, the application purpose, the desired time, and the like. At this time, in order to control the refractive index difference between the oil phase part and the water phase part, it is possible to control the content of the moisturizing agent included in the water phase and the oil added to the oil phase part. More specifically, in order to lower the refractive index difference, A method in which the content of oil, glycerin or saccharides is increased, the content of oil contained in the oil phase is lowered or the oil having a low refractive index is used. On the other hand, in order to increase the difference in refractive index, a polyhydric alcohol, A method of lowering the content of oils or saccharides or raising the content or refractive index of the oil phase oil may be adopted.

In the hydrogel mask composition of the present invention, the water receiving portion may include a conventional humectant, a gelling polymer and purified water, Ulleungdo Trilobal Extract, and the like.

As the moisturizing agent, any conventional cosmetic moisturizing agent for supplying moisture to the skin may be used. Examples of the moisturizing agent include polyhydric alcohols such as butylene glycol, propylene glycol, pentylene glycol, hexylene glycol, and polyethylene glycol Ryu; Glycerin such as glycerin, diglycerin and polyglycerin; And saccharides such as sorbitol multitol, sucrose, starch sugar, and racquitol, but the present invention is not limited thereto. The amount of the moisturizing agent may be 1 to 70% by weight, preferably 5 to 45% by weight based on the total weight of the composition. If the amount is less than 1% by weight, the difference in refractive index between the upper part and the upper part becomes too large, If it is more than 10% by weight, the difference between the refractive indexes of the upper part and the upper part becomes too low, and it becomes difficult to realize the milky white color.

The gelling polymer may be any conventional gelling polymer used in the form of a hydrogel mask of the cosmetic composition. Examples of the gelling polymer include galactomannan, glucomannan, guar gum, rocastine gum, Natural saccharides such as nickel, agar, algin, carrageenan, xanthan, gellan, gelatin, methylcellulose, cellulose, carboxymethylcellulose and hydroxyethylcellulose; And a hydrophilic gelling agent such as polyacrylate or its salt, polymethacrylic acid, carboxyvinyl polymer, polyvinyl alcohol, polyacrylamide, polyethylene oxide, polyethyleneimine, polyvinylpyrrolidone and the like. The gelation polymer may be contained in an amount of 0.1 to 10% by weight, preferably 0.5 to 5% by weight, based on the total weight of the composition. When the gelation polymer is less than 0.1% by weight, It may be difficult to maintain the shape and the elasticity may be deteriorated because the softness of the gel is increased when the content is more than 10% by weight.

The purified water is purified water used for cosmetics, and may contain 5 to 90% by weight, preferably 10 to 60% by weight based on the total weight of the cosmetic. When the purified water is less than 10% by weight, the gel is hardened due to the curing of the gel. Therefore, when it is applied to the skin, the adhesiveness may deteriorate and the difference in refractive index between the water layer and the oil layer becomes too large to change the transparency. The difference in the refractive index between the water layer and the oil phase becomes too low to make the milky white color difficult, and the softening of the gel becomes severe, so that it is difficult to maintain the shape and the elasticity may be deteriorated.

Further, in the cosmetic composition of the present invention, the oily portion may contain conventional oils and surfactants.

The oil may be any oil conventionally used in cosmetic compositions. Examples of the oil include isopropyl myristate, ethyl laurate, ethyl myristate, isopropyl palmitate, butyl laurate, Ester oils such as lactose, caprylic / capric triglyceride, butyleneglycolic dicaprylate / dicaprate, isopropyl myristate, triethylhexanoin, cetyl ethylhexanoate, octyldodecanol and polyol esters ; Hydrocarbon oils such as cyclododecane, isooctane, liquid paraffin, vaseline, hydrogenated polydecene, cyclooctane, cyclopentane and squalene; Waxes such as microcrystalline wax, beeswax, lanolin wax, ozokerite wax, candelilla wax, carnauba wax and synthetic wax; Jojoba Oil, Avocado Oil, Almond Oil, Olive Oil, Sesame Oil, Wheat Germ Oil, Four Flower Oil, Camellia Oil, Castor Oil, Grape Seed Oil, Green Tea Seed Oil, Macadamia Nut Oil, Palm Oil, Rosehip Oil, Natural oils such as wood oil, argan tree trunk oil and lavender oil, and silicone oils such as cyclomethicone, phenyltrimethicone, cyclopentasiloxane and dimethicone. It is not. According to one preferred embodiment of the present invention, olive oil, dimethicone, caprylic / capric triglyceride, cetyl ethylhexanoate, liquid paraffin or mixtures thereof can be used. The oil may be contained in an amount of 0.05 to 50.00% by weight, preferably 5 to 20% by weight based on the total weight of the composition of the present invention. When the oil is less than 0.05% by weight, it is difficult to implement the milky white color of the hydrogel mask. It is difficult to form an oil-in-water type emulsion, which may result in poor formulation stability.

The surfactant may be any surfactant conventionally used for the implementation and maintenance of the oil-in-water type of cosmetic composition. Examples of the surfactant include sorbitan stearate, sorbitan laurate, sorbitan palmitate, Ester-based nonionic surfactants of polyhydric alcohols such as glyceryl stearate and polyglyceryl stearate and fatty acids; Nonionic surfactants of aliphatic polyoxyethylene polymerization type such as polyoxyethylene stearyl ether and polyoxyethylene oleate; Polyoxyethylene ether nonionic surfactants of sorbitan esters such as polyoxyethylene sorbitan stearate, polyoxyethylene sorbitan laurate, polyoxyethylene sorbitan oleate, and polyoxyethylene sorbitol hexaoleate; Polyoxyethylene ether nonionic surfactants such as polyoxyethylene hydrogenated castor oil and the like; Polyoxyethylene ether nonionic surfactants of polyoxypropylene such as Poloxamer 168 and Poloxamer 407; Alkaline anionic surfactants such as sodium stearate, potassium stearate and sodium laurate, and neutral anionic surfactants such as sodium lauryl sulfate, sodium laureth sulfate, ammonium laureth sulfate, and potassium cetyl phosphate. But it is not limited thereto. The surfactant may be included in an amount of 0 to 10% by weight, preferably 0 to 5% by weight, based on the total weight of the composition. If the surfactant is used in an amount of more than 10.00% by weight, skin irritation may be induced and the gelation of the gelation polymer may be inhibited It is not appropriate to do it.
