Cleansing Cosmetic Composition {CLEANSING COSMETIC COMPOSITION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleansing cosmetic composition, and more particularly, to a cleansing cosmetic composition having an excellent cleansing effect and cleansing properties after cleansing and forming a stable three-layer property.

In general, cleansing products are cosmetics used to clean the skin and remove makeup residues, sweat, sebum, dust, and other waste products such as dead skin cells and other contaminants to keep skin condition moist and healthy. There is a function to let it.

Cleansing agents are largely divided into aqueous cleansing and oily cleansing according to the nature of the composition. Specifically, cleansing products include cleansing water, oil-in-water cleansing lotions, and foam cleansers. Oily cleansing products also include cleansing oils, water-in-oil (W / O) cleansing lotions, and cleansing creams.

Among them, the cleansing oil has an excellent cleaning power for the makeup residues, and since the cleansing oil has the simplicity of being washed out with water, the amount of the cleansing oil has recently increased.

However, conventional cleansing oils still have a problem that the effect of being able to simultaneously remove base makeup such as point makeup and foundation such as lipstick, eye shadow, mascara and the like remains. Accordingly, many studies have been made on how to improve the cleaning power of the cleansing oil.

Along with the research on the improvement of the cleansing power of the cleansing oil as described above, research on the cleansing composition forming the properties of two or more layers has been actively conducted.

Among them, Korean Patent Laid-Open Publication No. 2003-0043810 discloses a cleansing composition having a three-layered appearance using water, polyhydric alcohol, and cyclomethicone.

However, the composition according to the 2003-0043810 is not clear between the layers, there is a problem that the cleansing effect is reduced by using the cyclomethicon as the main substrate.

In view of the problems of the conventional cleansing cosmetic composition as described above, an object of the present invention is to provide a cleansing cosmetic composition excellent in the cleansing effect and cleansing after cleansing, forming a stable three-layer properties.

In order to achieve the above object,

Per 100 parts by weight of the total composition,

(Iii) iii a) 3 to 50 parts by weight of polar oil, and

b) a first layer comprising 3 to 50 parts by weight of nonpolar oil;

(Ii) vc) a second layer comprising 3 to 40 parts by weight of a hydrophilic surfactant; And

(Iii) 5 d to 50 parts by weight of polyol 폴리, and

     e) third layer comprising 1 to 15 parts by weight of ethanol

It provides a cleansing cosmetic composition comprising a.

In particular, it is preferable that the composition according to the present invention form three or more phases.

Hereinafter, the present invention will be described in detail.

The inventors of the present invention have completed the present invention from the fact that when the components having different cleansing effects and cleansing properties and different solubility indices and specific gravity in the cleansing cosmetic composition can be visually differentiated by forming a stable three-layer property.

Cleansing cosmetic composition according to the present invention

(Iii) a first layer comprising a) polar oil and b) nonpolar oil;

(Ii) c) a second layer comprising a hydrophilic surfactant; And

(Iii) a third layer comprising d) a polyol and e) ethanol

.

In the composition according to the present invention, the third layer, the second layer, and the first layer are sequentially positioned from below. The composition according to the present invention is present in a state in which the layers are not mixed with each other in a stable state, and when the energy is applied to the composition by shaking or stirring, the layers are uniformly mixed.

Hereinafter, each layer of the cleansing cosmetic composition according to the present invention will be described in detail.

The first layer (?) Located at the top of the cleansing cosmetic composition of the present invention comprises a) polar oil and b) nonpolar oil.

In the cleansing cosmetic composition of the present invention, the first layer (i) located at the top comprises a) polar oil and b) nonpolar oil.

The first layer is preferably adjusted to the solubility index and specific gravity to be located at the top of the composition, specifically, the solubility index is 5.0 to 9.5, it is preferable that the specific gravity is 0.97 to 0.99.

The first layer may be used a) 3 to 50 parts by weight of a) polar oil with respect to 100 parts by weight of the total composition. That is, it is preferable to include 3 parts by weight or more in order to form a three-layer property, it is preferable to include 50 parts by weight or less in order to maintain the height between the layers. In addition, when a large amount of polar oil is used, the interlayer spacing is not constant, thereby lowering the marketability.

The a) polar oil is preferably at least one selected from the group consisting of octyldodecanol, isononylnonanoate, isocetylethylhexanoate and capriccaprylic triglycerite.

In addition, the first layer may be used in 3 to 50 parts by weight of b) non-polar oil based on 100 parts by weight of the total composition. That is, it is preferable to include 3 parts by weight or more in order to form a three-layer property, it is preferably included in 50 parts by weight or less in order to maintain the interlayer height and cleansing force.

The b) non-polar oil is preferably used at least one selected from the group consisting of hydrocarbon oil, squalane and polyisobutene.

In the cleansing cosmetic composition of the present invention (ii) the second layer is located between the first layer and the third layer to be described later, and c) a hydrophilic surfactant.

The second layer is preferably adjusted to the solubility index and specific gravity to be located between the first layer and the third layer of the composition, specifically, the solubility index is 10 to 11, it is preferable that the specific gravity is 0.96 to 1.0.

The second layer may be used 3 to 40 parts by weight of c) hydrophilic surfactant based on 100 parts by weight of the total composition. That is, it is preferable to include 3 parts by weight or more in order to easily wash off with water after cleansing, and to include 40 parts by weight or less in consideration of skin stability.

The c) hydrophilic surfactant is preferably used at least one selected from the group consisting of POE, PPG or a derivative thereof dissolved in oil.

In the cleansing cosmetic composition of the present invention, the third layer (iii) located at the bottom includes d) a polyol and e) ethanol.

The third layer is preferably adjusted to the solubility index and specific gravity to be located at the bottom of the composition, specifically, the solubility index is 12.0 to 23.4, it is preferable that the specific gravity is 0.99 to 1.0.

The third layer may be used 5 to 50 parts by weight of the polyol d) with respect to 100 parts by weight of the total composition. That is, it is preferably included 5 parts by weight or more in order to form a three-layer property and to impart a moisturizing power after cleansing, it is preferably included in 50 parts by weight or less in order to maintain the cleansing force. When the polyol is out of the above law, the three-layer property is not formed or the cleansing effect is deteriorated.

The d) polyol is preferably used at least one selected from the group consisting of glycerin, propylene glycol, butylene glycol and dipropylene glycol.

In addition, the third layer may be used 1 to 15 parts by weight of e) ethanol with respect to 100 parts by weight of the total composition. That is, it is preferable that 1 part by weight or more is included to make the three-layer separation more clear, and 15 parts by weight or less is preferably included to maintain the three-layer property.

In addition, the cleansing cream cosmetic composition of the present invention may further include additives commonly used in cleansing cream cosmetic compositions such as skin protectants within the range of not impairing the effect of the composition, in addition to the components a) to e). It may be included as a balance.

On the other hand, the cleansing cosmetic composition of the present invention comprising the above configuration may form three or more properties.

The present invention provides a cleansing cream cosmetic composition that is excellent in cleansing effect and cleansing after cleansing, and forms a stable three-layer property by using components having different solubility indices and specific gravity.
