Description

[0001] The present invention relates to a cosmetic composition to react specifically with soap,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic composition comprising a soap sensor, and more particularly, to a cosmetic composition which is easy to clean by including a soap sensor.

Hyundai is a society where appearance is very competitive. As a result, there is growing interest in making appearance and expressing personality with makeup. The makeup covers the defects by applying cosmetics on the face, expresses the unique beauty by emphasizing the advantages, and protects the skin from external stimuli such as ultraviolet rays. There are various kinds of make-up cosmetics such as make-up base, foundation, tuyen cake, bib cream, seed cream, sun cream, eye shadow, lipstick, mascara and eyeliner.

On the other hand, in recent years, it is becoming more important to erase than to make up by the trend of "during". In recent years, the make-up products that are being released are excellent in skin adhesion for expressing excellent skin, and are manufactured so that colors are clearly colored and water repellent, requiring more thorough cleansing.

In general, makeup users use cleansing cream or oil as the first cleansing to erase the make-up, erase the make-up, and then use the cleansing agent such as soap or cleansing foam as a secondary cleansing. In addition, the color cosmetics are not well cleansed, so they may be further cleansed using the respective removers.

Such various cleansing steps take away the moisture and oil of the skin more than necessary and irritate the skin, thereby causing trouble to the skin. In order to solve such problems, a cleansing tool such as a natural soap containing various natural substances and an effective ingredient, cleansing foam of various formulations, a brush, a vibrator and the like has been developed.

However, cleansing still takes place through several steps. Accordingly, there is a need for a method that satisfies both makeup and cleansing at the same time.

Korean Patent Laid-Open No. 10-2011-0059986 (the name of the invention: make-up cosmetic composition for water-in-oil type for skin improvement) describes a water-in-oil type makeup cosmetic composition containing a ceramide analogous amino acid derivative, a papain enzyme capsule and a polysaccharide as an active ingredient have. Korean Patent No. 10-1284426 (a cosmetic made using a mixed solvent of ethanol, water, and glycerin) contains a mixture 60 of 90 to 98 wt% of makeup powder and 2 to 10 wt% of binder To 70% by weight and 60 to 80% by weight of ethanol, 1 to 10% by weight of glycerin and 40 to 30% by weight of a mixed solvent of water.

Disclosure of the Invention An object of the present invention is to provide a cosmetic composition which can be easily cleaned by dispersing a water-repellent powder in an aqueous phase and simultaneously applying a hydrophilic emulsifier and a lipophilic emulsifier.

To achieve the above object, the present invention provides a cosmetic composition comprising an aqueous phase and an oil phase, and more specifically, a cosmetic composition comprising an aqueous phase and an oil phase, wherein the aqueous phase comprises a water-soluble polymer, a water-repellent powder and purified water, The present invention provides a cosmetic composition comprising an oil, a hydrophilic emulsifier having an HLB number of 8 to 18, and a lipophilic emulsifier having an HLB number of 2 to 6.

The present invention disperses the water repellent powder in the water phase, whereby the cosmetic film exhibits water repellency. Therefore, the cosmetic film is prevented from being washed down by sweat or water. However, when the water-repellent powder is added to the oil phase rather than to the water phase, the above-mentioned effect of the present invention can not be obtained.

On the other hand, in the present invention, a lipophilic emulsifier and a hydrophilic emulsifier are added so that a soap sensor function is developed which is not easily cleansed in water but is easily cleansed by washing with soap.

On the other hand, in the cosmetic composition of the present invention, the aqueous phase may preferably be composed of 0.1 to 10% by weight of the water-soluble polymer, 1 to 30% by weight of the water-repellent powder and the remaining amount of purified water.

The water-soluble polymer of the water phase is preferably selected from the group consisting of Xanthan gum, Arabic gum, Carrageenan gum, Locustbean gum, Alginate gum, Guar gum, And Cellulose gum. [0034] The term " cellulosic "

The water repellent powder of the water phase is preferably prepared by coating a water repellent material with a core having a high refractive index as a core. The high refractive index component is excellent in the effect of shielding skin dirt and the like due to good reflection, and the water repellent powder imparts skin adhesion and makeup persistence of the cosmetic composition.

The component having a high refractive index may be any one selected from the group consisting of barium sulfate, zinc oxide, and titanium dioxide.

The water repellent material may be any one selected from the group consisting of Dimethicone, Alkylsilane, vegetable wax, fluorine compound, and fatty acid.

On the other hand, in the cosmetic composition of the present invention, the oil phase preferably contains 20 to 60% by weight of an oil, 0.1 to 40% by weight of a hydrophilic emulsifier having an HLB number of 8 to 18 and 0.1 to 40% by weight of a lipophilic emulsifier having an HLB number of 2 to 6, 40% by weight.

The oil phase is prepared by adding 0.1 to 40% by weight of a hydrophilic emulsifier having an HLB number of 8 to 18 and 0.1 to 40% by weight of a lipophilic emulsifying agent having an HLB number of 2 to 6. When the cosmetic composition is prepared as described above, It is possible to provide a cosmetic composition in which the make-up is not easily cleansed with perspiration but is easily cleansed with soap.

The oil may be any one selected from the group consisting of an ester oil group, a hydrocarbon oil group, a silicone oil group, and a fluorine oil group have.

The hydrophilic emulsifier preferably has a hydrophilic lipophilic balance (HLB) number of 8 to 18. For example, sorbitan monolaurate (Span 20, HLB: 8.6), polyethylene glycol monostearate (HLB: 11.6), sorbitan laurate (Tween 20, HLB: 16.7) And may be at least one selected from the group consisting of sorbitan stearate (Tween 60, HLB: 14.9) and sorbitan trioleate (Tween 85, HLB: 11.0).

The lipophilic emulsifier preferably has a hydrophilic lipophilic balance (HLB) number of 2 to 6. For example, it is selected from the group consisting of glyceryl mono stearate (HLB: 3.8), sorbitan stearate (HLB: 4.7) and sorbitan sequioleate (HLB: 3.7) It can be any one or more.

On the other hand, in the cosmetic composition of the present invention, a pigment may be further added to the water or oil phase for color rendering. At this time, an iron oxide based pigment can be used.

On the other hand, the cosmetic composition of the present invention can be prepared by mixing the water phase and the oil phase, and then dispersing the oil phase with a homogenizer. At this time, carbomer may be preferably used as the incrementing agent. At this time, the carbomer may be added in an amount of 0.05 to 5 parts by weight based on the total weight of the cosmetic composition.

The external phase (continuous phase) of the cosmetic composition of the present invention prepared as described above is an aqueous phase in which a water-soluble polymer and a water-soluble pigment are dissolved, and an inner phase (dispersed phase) composed of oil, liposoluble pigment, hydrophilic emulsifier and lipophilic emulsifier is dispersed And stabilized.

When the cosmetic composition of the present invention is spread on the skin, the oil phase becomes a foreign phase (continuous phase) due to the force, and reverse dispersion occurs in which the aqueous phase becomes an internal phase (dispersed phase). This is a phenomenon caused by the hydrophilic emulsifying agent and the lipophilic emulsifying agent acting as a reversed dispersing agent by the combined action. As a result, the water phase moves closer to the skin and the oil phase moves to the outside (surface). Thereafter, the water-soluble polymers dissolved in the water phase aggregate to form a thin layer. This layer reacts with the soap of the soap and has a soap sensor (soap-specific reaction) function that can simply remove make-up with a single rinse. In addition, a cosmetic composition having water resistance and hiding power can be produced by the above movement.

On the other hand, the cosmetic composition of the present invention acts as a base and can be used in various formulations. For example, it may be any one selected from cosmetic formulations comprising a makeup base, a foundation, a skin cover, a face powder, a two-way cake, a lipstick, a lip gloss, an eye shadow, a cheek color and an eyebrow pencil. It may also optionally be applied to the skin in the form of an aerosol, or it may be in solid form, e.g., in the form of a stick.

On the other hand, the cosmetic composition of the present invention can be prepared by appropriately selecting components contained in a conventional emulsified cosmetic composition, that is, moisturizing components such as antioxidants, polyhydric alcohols and hyaluronic acid, various vitamins, preservatives, coloring agents, perfumes, Can be added.

The composition of the present invention disperses the water-repellent powder in water phase, and simultaneously applies a hydrophilic emulsifier having an HLB number of 8 to 18 and a lipophilic emulsifier having an HLB number of 2 to 6, The soap has a characteristic that it reacts specifically and is very easy to clean.
