Description

Eye make-up composition containing pigment coated with keratin}

The present invention relates to an eye cosmetic composition, and more particularly to an eye cosmetic composition containing a pigment coated with keratin, a component having excellent affinity with epithelial tissue, thereby improving adhesion and sustainability.

Conventional mascara or eyeliner used for eye makeup has a problem in that adhesion and persistence are remarkably inferior after time of makeup. For example, when using a black mascara, etc., the black powder of the mascara composition falls under the eyes, so it is not aesthetically pleasing, and the eyeliner has a problem of spreading due to lack of persistence.

This problem is understood to be due to a poor affinity with the epithelial tissue for the pigments used in conventional eye cosmetic compositions.

Conventional technologies that can be contrasted with the present invention include "Long Lash type mascara composition using Hanji" described in Korean Patent Registration No. 166632 (registered on September 24, 1998). In the prior art, 0.10 to 30.00% by weight of Hanji, 30.00 to 35.00% by weight of wax, 1.00 to 2.00% by weight of emulsifier, 0.50 to 3.00% by weight of resin, 7.00 to 8.00% by weight of colorant, 0.50 to 2.00% by weight of keratin, and 0.20% of preservative %, 0.20% by weight of silicon and 50.00 ~ 60.00% by weight of purified water, and it is characterized by improving the feeling of pressure on the edge of the eye with the main ingredient as a main ingredient that is comfortable to wear without giving a feeling of pressure even if worn for a long time .

Although a small amount of keratin (0.50 to 2.00% by weight) is used in the related art, not only keratin itself is included as a component of the composition, but also a colorant as a component separate from keratin in the composition. Therefore, there is a disadvantage that it is difficult to expect the adhesion and the sustaining effect due to the affinity with the epithelial tissue by keratin at the time of coloring.

The present invention is to solve the problems of the prior art as described above, an object of the present invention, to improve the adhesion and persistence of the cosmetic composition for the eyes, the composition of the pigment coated with keratin is a component having excellent affinity with epithelial tissue It is to provide an eye cosmetic composition containing as a component.

The present inventors compared silicone oil, keratin, lecithin and the like as the materials used for the pigment coating, and found that the pigment coated with keratin had the best affinity with the epithelial tissue, and thus was used in the cosmetic composition for eye use. This excellent thing was confirmed.

Keratin is a protein that forms epithelial tissues such as hair and eyelashes. The chemical composition is 50.65% carbon, 20.85% oxygen, 17.14% nitrogen, 6.36% hydrogen, and 5.0% sulfur. The keratin used in the coating in the present invention is an animal keratin obtained from merino wool (a kind of fleece), and specifically, "Keratin Hydrolsate W20" of HENKEL (Germany Dusseldorf) is used. "Keratin Hydrolsate W20" is a hydrolyzed keratin solution with a solid content of keratin of about 20 parts by weight.

Raw pigments coated with keratin in the present invention include those commonly used, specifically iron oxide, chromium oxide green, chromium hydroxide green, ultramarine (Ultramarine Blue, Ultramarine Pink, Ultramarine Violet, etc.), titanium Oxide (Micro Titanium Dioxide MT-500B, Titanium Dioxide, C475175 Cosmetic White, BTD 401, etc.), mica (Sericite, Mica, Micro Mica, Silk Mice, etc.), Red 202 Cal Lake (DC Red # 7 Calcium-lake ), And the like.

First, the content of keratin contained in the coated pigment is important, the content of keratin in the coated pigment is 10 to 50 parts by weight, more preferably 20 to 30 parts by weight. If the content of keratin contained in the coated pigment is less than 10 parts by weight, affinity with epithelial tissue around the eyes cannot be expected, and if the content of keratin contained in the coated pigment exceeds 50 parts by weight, The high viscosity makes it difficult to maintain a creamy viscosity that is suitable for application around the eyes.

The content of the pigment coated with keratin in the whole eye cosmetic composition according to the present invention is suitable 5 to 25 parts by weight. When the amount is less than 5 parts by weight, the color of the pigment itself is small, so that the color is not represented in a normal manner. When the amount is more than 25 parts by weight, the adhesion force is rather reduced, resulting in powder falling off.

On the other hand, there is a film former as a component for determining the drying rate of the eye cosmetic composition, and generally an acrylate copolymer is used. In the case of using the conventional acrylate copolymer as a film forming agent in an eye cosmetic composition containing a pigment coated with keratin as in the present invention, the drying speed is high, so that drying proceeds during application of the composition around the eyes. .

Therefore, in order to control the drying rate of the eye cosmetic composition by this invention, a diglycol / cyclohexane dimethanol / isophthalate / sulfoisophthalate copolymer is used together with an acrylate copolymer as a film former. The content of the diglycol / cyclohexanedimethanol / isophthalate / sulfurisophthalate copolymer is suitably 10 to 40 parts by weight, more preferably 10 to 20 parts by weight based on the weight of the acrylate copolymer.

Typically, the cosmetic composition for the eyes is a generic term for the cosmetics used around the eyes, mascara, liquid eyeliner, eye shadow, eyeliner pencil, eyebrow pencil and the like. In the examples below, the mascara and the liquid eyeliner are compared with the composition according to the present invention. However, application of the eye cosmetic composition according to the present invention is not limited to mascara and liquid eyeliner.

<Test 2>

In order to test the sustainability of mascara prepared from the compositions according to Comparative Example 1 and Examples 1 and 2, and 3, the water resistance and oil resistance tests of each composition were tested and the results are summarized in Table 3 below.

Water resistance test method

-Apply mascara contents to glass by using applicator to the same thickness.

-Completely dry the applied contents.

After completely drying, repeat the operation of putting the glass plate in water and releasing it three times and observe the state of the glass plate.

-After that, immerse the glass plate in water for 10 minutes and take it out to observe the state of the glass plate.

-It is judged that less than 10% of the total coating area is in water and good when 10 ~ 20% is in water, and more than 20% is bad in water.

Oil Resistance Test Method

-Apply the mascara contents to the glass plate with the same thickness by using applicator.

-Completely dry the applied contents.

After completely drying, repeat the operation of putting the glass plate in and out of the silicone oil three times and observe the state of the glass plate.

-After soaking the glass plate in silicone oil for 10 minutes, take it out and observe the condition of the glass plate.

-If the content applied to the glass plate is less than 10% of the total application area in the silicone oil, it is good. If 10 to 20% is in the silicone oil, it is generally considered bad.

In Table 3 below, 'O' is good, 'Δ' is usually good, and '×' is bad.
