Description

An eyemake-up cosmetic composition of water-dispersion type comprising pretreated activated charcoal}

The present invention relates to a water-dispersible formulation eye makeup cosmetic composition having excellent color expressing power and less strain on the eyes, and more particularly, contains an activated carbon pretreated in three steps or an acrylic copolymer mixed with a plasticizer. The present invention relates to a water-dispersible formulation eye makeup cosmetic composition having excellent color expressing power, water resistance and durability, and a low burden on the eyes.

In general, eye makeup cosmetic compositions in water dispersible formulations such as eyeliners, mascara, eye shadows and eyebrows contain iron oxide pigments and short chain polymers. However, the contents of heavy metals contained in iron oxide, the persistence and water resistance of short-chain polymers, the burden on the eyes, and the like have been problematic. That is, a large amount of iron oxide is used to increase color expressive power, and short-chain polymers such as polyalkyl ester, polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP) and thickeners are used to increase the persistence and water resistance. Since it has been used in a large amount, the heavy metal content is relatively high, and the burden on the eyes is relatively high due to the formation of a thick film film, there is a problem that the feeling of pulling or skin tightness is felt and the lines are bundled.

Accordingly, the present inventors have conducted research to solve the above problems, and as a result, the water-dispersion formulation eye makeup composition is removed from the alkali components on the surface by a pretreatment process, and has an average particle size of 0.1 to 0.5 µm and a water content of 0.5. The present invention has been accomplished by discovering that the above object can be achieved by containing activated carbon adjusted to below%.

In addition, the inventors have found that the above-mentioned problems can be more effectively solved when the water-dispersible formulation eye makeup composition further comprises a mixture of an acrylic copolymer and a plasticizer in a ratio of about 10: 1.

Accordingly, it is an object of the present invention to provide a water-dispersible formulation eye makeup composition which is excellent in color expressing power, water resistance and durability, and has a low burden on the eyes.

In order to achieve the above object, the water-dispersible formulation eye makeup composition according to the present invention contains activated carbon pretreated so that the water content is 0.5% or less and the average particle size is 0.1 to 0.5 탆 in an amount of 10.0 to 20.0% by weight. It is characterized by.

Hereinafter, the present invention will be described in more detail.

The water dispersion formulation eye makeup composition of the present invention contains a large amount of heavy metal by removing the alkali component on the surface by pretreatment and containing activated carbon having a water content of 0.5% or less and a particle size of 0.1 to 0.5 탆. It is applied to the skin smoothly without the use of color.

If the general activated carbon is used as it is in the make-up cosmetics of the water dispersion formulation, the eye irritation may be caused by the alkali component on the surface of the activated carbon, the particles are entangled with each other, and the dispersion force is remarkably decreased. This sadness is not applied smoothly and the powder is blown after drying, the formed film is not smooth, and the durability and water resistance are remarkably lowered, and the color expressing power is also lowered. For this reason, in the composition of this invention, the alkaline component is removed by the three-step pretreatment process, and the activated carbon which adjusted the water content to 0.5% or less and the particle size size to 0.1-0.5 micrometer is used.

Pretreatment process of activated carbon,

1) washing activated carbon 2 to 3 times with ethyl alcohol, and then distilling the mixture into distilled water 3 to 4 times, followed by filtration;

2) heat drying at a temperature of 500 to 600 ° C. for 6 to 8 hours with a heat dryer; And

3) first grinding for about 30 minutes with a trigger mill (manufactured by retsch, Germany), and then second grinding using an airzetmill at a speed of 10,000 to 20,000 rpm;

It includes.

That is, in general, alkali in the activated carbon treated with alkali causes skin irritation and eye irritation, and thus, removes the alkali component in the activated carbon through the first process, and if the moisture content is high, it is easily contaminated by microorganisms, causing anomalous, Since problems such as discoloration may occur, the water content is adjusted to 0.5% or less through the second process, and the uniformity of 0.1 to 0.5 μm is achieved through the third process to minimize particle entanglement and have the best color development. Create particles of size Since the pretreated activated carbon has a uniform particle size of 0.1 to 0.5 占 퐉, the dispersing efficiency is high and the skin is smoothly applied to provide excellent color expression, and the formed film is smooth and has excellent durability and water resistance.

Thus, the eye makeup composition of the aqueous dispersion formulation of the present invention contains the activated carbon pretreated by the above-described method in an amount of 10.0 to 20.0% by weight based on the total weight of the composition.

On the other hand, the activated carbon pretreated by the above-described method is very wide application field, it can be used for pigments of foundations in addition to the eye makeup composition of the water dispersion formulation of the present invention. That is, during pigmentation of the foundations, it may be used in the amount of about 0.1 to 2.0% by weight of the total content of the pigment for coloring instead of the pigment of the iron oxide type as a black pigment.

The eye makeup composition of the water dispersion formulation of the present invention may contain an acrylic copolymer together with the pretreated activated carbon. In other words, acrylic copolymers are more durable than short-chain polymers, have good adhesion to the skin, and are easy to disperse pigments due to the presence of thickeners and pigments within the crosslinked structure. Since it has a bonding structure, since it has strong durability and water resistance, it can be contained together with the pretreated activated carbon.

However, when the acrylic copolymer is used alone, the particle is not entangled and the surface is smooth and has excellent color expressing properties, but the burden on the eyes due to the formation of a rigid film can be increased, the water-dispersible formulation of the present invention The eye makeup composition may contain a mixture of an acrylic copolymer and a plasticizer in a ratio of about 10: 1 together with the pretreated activated carbon.

The acrylic copolymer used in the present invention is a copolymer formed by crosslinking polymerization based on acrylate, and the kind thereof is not particularly limited, but for example, acrylate / acrylamide copolymer, acrylate / acetoacetoxyethyl As meta-acrylate copolymer, acrylate / C _10-30 alkylacrylate crosspolymer, arylate copolymer, arylate / vinylacetate (VA) copolymer, arylate / polyvinylpyrrolidone (PVP) copolymer At least one selected from the group consisting of.

The plasticizer used in the present invention is not particularly limited, and those used in the art are appropriately selected and used.

In the composition of the present invention, the mixture of the acrylic copolymer and the plasticizer is preferably used in an amount of 20.0 to 40.0% by weight based on the total weight of the composition.

The water-dispersible formulation eye makeup cosmetic composition of the present invention is not particularly limited in the formulation, and may have a formulation such as, for example, eyeliner, mascara, eye shadow, eyebrow, and the like.

In addition, the eye makeup cosmetic composition of each formulation may be appropriately selected and blended by those skilled in the art according to the formulation and the purpose of use of the other cosmetics other than the above-mentioned pretreated activated carbon and the mixture of the acrylic copolymer and the plasticizer. However, the present invention is not limited only to these examples.

Hereinafter, the present invention will be described in detail with reference to Examples and Test Examples.
