Abstract

The present invention relates to a cosmetic composition, in which a high-content of oil-soluble components is stabilized using a natural surfactant, and more specifically to a cosmetic composition, in which by using a plant-derived natural surfactant and a high-pressure emulsification method without using PEG-based or ionic surfactants that may cause skin irritation, a transparent gel formulation containing a high-content of oil-soluble components can be realized, thereby effectively combining the advantage of an oil formulation excellent in moisturizing power, and the advantages of a moisture gel formulation, which is easy to use without flowing down, and has a fresh feeling of use.

First claim

1 . A cosmetic composition comprising a plant-derived surfactant; and an oil-soluble component.

2 . The cosmetic composition of claim 1 , wherein the plant-derived surfactant consists of at least one selected from the group consisting of an alkyl glucoside-based surfactant and methyl glucoside sesquistearate; and a polyglyceryl-based surfactant.

3 . The cosmetic composition of claim 2 , wherein the polyglyceryl-based surfactant is at least one selected from the group consisting of polyglyceryl-3 methyl glucose distearate, polyglyceryl-2 stearate and polyglyceryl-10 stearate.

4 . The cosmetic composition of claim 2 , wherein the alkyl glucoside-based surfactant is at least one selected from the group consisting of cetearyl glucoside, decyl glucoside, coco-glucoside, C 12-20 alkyl glucoside and C 10-16 alkyl glucoside.

5 . The cosmetic composition of claim 1 , wherein the plant-derived surfactant is a mixture of polyglyceryl-3 methyl glucose distearate, methyl glucose sesquistearate and cetearyl glucoside.

6 . The cosmetic composition of claim 1 , wherein the plant-derived surfactant is used in an amount of 0.10 to 0.20 parts by weight based on part by weight of the oil-soluble component.

7 . The cosmetic composition of claim 2 , wherein the alkyl glucoside-based surfactant and methyl glucose sesquistearate are each mixed at a ratio of 0.01 to 0.17 parts by weight based on 1 part by weight of the polyglyceryl-based surfactant.

8 . The cosmetic composition of claim 5 , wherein methyl glucose sesquistearate is mixed at a ratio of 0.01 to 0.17 parts by weight, and cetearyl glucoside is mixed at a ratio of 0.01 to 0.17 parts by weight based on 1 part by weight of the polyglyceryl-3 methyl glucoside distearate.

9 . The cosmetic composition of claim 1 , wherein the oil-soluble component is contained in an amount of 10 to 60% by weight based on the total weight of the composition.

10 . The cosmetic composition of claim 1 , wherein the oil-soluble component is present in the form of particles having a size of 200 nm or less.

11 . The cosmetic composition of claim 1 , wherein the oil-soluble component is at least one selected from the group consisting of fat including shea butter, mango seed butter and cacao seed butter; wax including myristyl myristate, camellia sinensis leaf extract, jojoba, sunflower seed, carnauba wax, candelilla wax and beeswax; higher alcohol including cetyl alcohol, stearyl alcohol and behenyl alcohol; higher fatty acid including caprylic/capric triglyceride, lauric acid, myristic acid, palmitic acid and stearic acid; hydrocarbon including ceresin; natural oil including meadowfoam seed oil, sunflower seed oil, macadamia seed oil, green tea seed oil, ginger oil, ginseng oil, coconut oil, olive oil and camellia oil; ester including phytosteryl/octyldodecyl lauroyl glutamate, isostearyl isostearate, methylheptyl isostearate, dicaprylyl carbonate and isopropyl palmitate; ether including dicaprylyl ether; silicone oils including dimethicone, cyclopentasiloxane, cyclohexasiloxane, phenyltrimethicone, trisiloxane and methyltrimethicone; and hydrocarbon including squalane.

12 . The cosmetic composition of claim 1 , wherein the composition is an oil-in-water type.

13 . The cosmetic composition of claim 1 , wherein the composition has a viscosity of 3,000 cps or higher.

14 . The cosmetic composition of claim 1 , wherein the composition is in the form of a transparent gel.

15 . The cosmetic composition of 1, wherein the composition undergoes a phase change from gel to oil upon application to the skin.
