Description

[0001] The present invention relates to a cosmetic composition for peel-off type cosmetic compositions for eyebrow tattoo with high tinting strength and easy viscosity controllability,

The present invention relates to a cosmetic composition for a peel-off type eyebrow tattoo, and more particularly, to a makeup composition for a peel-off type eyebrow tattoo which has excellent skin adhesion properties and has enhanced initial tincturing power and viscosity control, Compositions and methods of making the same.

Even if only one eyebrow is changed, the face image is different, and eyebrow is an important factor that determines the impression of a person. Therefore, many cosmetic products for developing eyebrows have been developed.

Conventionally, eyebrow cosmetics have been developed and used in the form of eyebrow pencil, mascara, etc., and it is troublesome to apply cosmetics every time, 0000193).

In order to compensate for this problem, semi-permanent eyebrow tattooing is sometimes performed. However, tattooing is disadvantageous in that it can not change the shape and color of the eyebrow once the skin is stimulated.

Recently, a skin color enhancing agent such as dihydroxyacetone (Japanese Patent Application Laid-Open No. 2006-063020) has been used to provide short-term (3 to 5 days) tattoos A composition for eyebrow coloring (tattooing) of a peel-off type has been developed.

However, in these compositions, polyvinyl alcohol (PVP) is mainly used as a film forming agent. When PVP is added in a certain amount or more, the viscosity of the PVP increases too much and the production process of the product is not easy and the skin wettability becomes worse, It was also disadvantageous that it was messed up with the pigment when it was removed, and it was contaminated around eyebrows.

Accordingly, development of a peel-off type eyebrow tattooing (coloring) composition which is excellent in initial coloring power and easy in viscosity control and excellent in skin-spreading ability and capable of producing various colors has been demanded.

As a result, they have found that when a combination of polyvinyl alcohol and polyurethane is used as a water-resistant adhesive in combination with an adhesive acrylate copolymer in a specific ratio, fine particles (having an average particle size of 0.1 to 0.2 μm ) Carbon black pigments are used together to obtain a composition for peel-off type eyebrow tattoo which is excellent in initial coloring power and easily controlled in viscosity and excellent in skin-spreading ability and capable of producing various colors And completed the present invention.

Accordingly, an object of the present invention is to provide a composition for an eyebrow tattoo of the peel-off type, which has excellent initial coloring power and is easily controlled in viscosity and is excellent in skin-spreading ability and capable of producing various colors.

Another object of the present invention is to provide a method for manufacturing a composition for eyebrow tattoo of peel-off type, which is excellent in initial coloring power and easy in viscosity control and excellent in skin-spreading ability and capable of producing various colors.

In order to achieve the object of the present invention, the present invention provides a film-forming composition comprising 15 to 20 wt% of a film forming agent, 5 to 10 wt% of a water-resistant adhesive, 0.5 to 7 wt% of a dye, 0.1 to 2.0 wt% of a pigment, 20% by weight, pH adjusting agent 0.1 to 0.5 % By weight, and the remaining purified water.

In the cosmetic composition for eyebrow tattooing of the present invention, the film-forming agent is a combination of polyvinyl alcohol (PVA) and polyurethane (PU).

The film forming agent in the present invention enables the composition of the present invention to be used as a film-forming and peeling-off peel-off type when applied to eyebrows. When the composition is formed into a film by the film-forming agent, it functions not only to increase the coloring power by electrodeposition with the skin of the colored region, but also protects it from moisture and causes coloration to occur well.

Polyvinyl alcohol has a film-forming function and is used in a nose pack, etc. It has a relatively short drying time, excellent adhesive force, strong coating film, biocompatibility, high mechanical properties and high water content. However, when the amount of polyvinyl alcohol is increased to increase the thickness or strength of the film when polyvinyl alcohol is used, the viscosity of the composition rapidly increases and it is difficult in the working process. Further, There is a problem that it rapidly deteriorates.

Therefore, the present invention is characterized in that polyurethane having characteristics such as excellent pigment dispersion stability, gloss, surface strength, abrasion resistance and water resistance is used in combination. Since the viscosity of the polyurethane is small, it is possible to freely adjust the viscosity according to the kind of the container. Therefore, it is possible to shorten the process time due to the ease of operation and to apply the composition to the skin with appropriate viscosity, There is a wide range of advantages. In addition, the polyurethane resin enhances the water resistance of the formed film to prevent it from peeling off with water or sweat, and increases the effect of coloring with strong adhesive force. Examples of the polyurethane that can be used in the present invention include Avalure UR 405, 425 and 450 (manufactured by NOVEON), but are not limited thereto.

In the cosmetic composition for eyebrow tattooing of the present invention, the film forming agent is preferably contained in an amount of 15 to 20% by weight, and if it is less than 15% by weight, the viscosity is low, And it is difficult to express detailed information.

In the film forming agent of the present invention, the weight ratio of polyvinyl alcohol to polyurethane is preferably 2 to 3: 1, and when the polyvinyl alcohol is less than 2 to 3 times, the viscosity is low, If it is 2 to 3 times, there is a problem in viscosity control.

In the cosmetic composition for eyebrow tattooing of the present invention, an acrylate copolymer having adhesiveness is used as a water-resistant adhesive.

Examples of the adhesive acrylate copolymer include YODOSOL GH800F and YODOSOL GH800PE (manufactured by Akzo Nobel).

In the composition of the present invention, the water-resistant adhesive imparts an initial fast drying when applied to eyebrows and improves the adhesion of the dye from the dye or pigment even after peeling off the film (coating film), thereby increasing the initial coloring power. In addition, the water-resistant adhesive is broken into small pieces at the time of peel-off, and is characterized in that it is cleanly wiped away without being dirty-dirty around the eyes such as crushed and smearing like pigment.

In the present invention, the water-resistant adhesive is preferably contained in an amount of 5 to 10% by weight, and if it is less than 5% by weight, the adhesive strength is low.

In the cosmetic composition for eyebrow tattooing of the present invention, the dyes may be appropriately mixed with yellow, red and blue dyes according to a desired color. The dye is preferably contained in an amount of 0.5 to 7% by weight, and when the amount is less than 0.5% by weight, the coloring effect is insignificant. When the amount is more than 7% by weight,

The cosmetic composition for eyebrow tattoo of the present invention may further comprise Of fine particles (average particle size of 0.1 to 0.2 mu m) And carbon black. In the present invention, the pigment increases the sustainability of the initial coloring and limits the color (red or yellow series) realized by only the dye. This makes it possible to realize a rich and diverse color (black, gray, etc.) when the pigment is used in combination. In the present invention, the pigment is preferably contained in an amount of 0.1 to 2.0% by weight. When the amount of the pigment is less than 0.1% by weight, there is a problem that the color is hardly displayed. When the amount of the pigment is more than 2.0% by weight, .

The eyebrow tattoo cosmetic composition of the present invention comprises 10 to 20% by weight of dihydroxyacetone. Dihydroxyacetone is a self-tanning ingredient that affects skin color and is used as a coloring aid. Dihydroxyacetone deposits the horny layer in brown color, and it has the property to return to its original skin color naturally after falling over time. When the composition of the present invention contains dihydroxyacetone in an amount of less than 10% by weight, the coloring enhancing effect may be deteriorated. When the amount of dihydroxyacetone is more than 20% by weight, the feeling and feeling- There is a problem that can be.

The composition of the present invention contains 0.1 to 0.5% by weight of a pH adjusting agent. As the pH adjusting agent, citric acid may be used, but is not limited thereto.

The composition of the present invention can be maintained at a pH of 3 to 5 by means of a pH adjusting agent in which the dihydroxyhexaton can maintain long-term stability.

The composition of the present invention uses purified water as a solvent.

The cosmetic composition for eyebrow tattooing of the present invention may further comprise an auxiliary solvent, a preservative, a moisturizing agent and a slip agent, if necessary.

Ethanol can be used as an auxiliary solvent, and it is suitable to use up to 3% by weight as an auxiliary solvent for facilitating drying.

Preservatives may be selected from parabens, phenoxyethanol, imidazolidinyl urea, sorbic acid, salicylic acid, and may be used in amounts specified by the Cosmetic Act.

The moisturizing agent may be selected from glycols usable in cosmetics such as propylene glycol, and 3 to 7% by weight is suitable. Moisturizers improve dryness and early wetting.

As the slip agent, oily flow can be used, and the formed film can be easily peeled off, thereby preventing skin damage to the eyebrow area, and can be used up to 1.0% by weight.

The cosmetic composition for eyebrow tattooing according to the present invention is applied to eyebrows, dried for about 20 to 30 minutes to form a film, maintained for about 2 to 3 hours to allow color to be deposited on the skin, and then peeled off from the eyebrow (Peel off). The color of the eyebrow area by the cosmetic composition for eyebrow tattoo of the present invention lasts for 3 to 5 days or more and shows a short-term tatoo effect. In particular, the film formed by the composition of the present invention has high adhesion to the skin and is colored well, so that the initial coloring power is high enough to prevent cleansing immediately after peeling off.
