Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gel-like hair dye having a smoothing power.

[0002]

2. Description of the Related Art Most of the hair dyes that are commonly used at present are two-pack type synthetic hair dyes. The first liquid is an acid dye, alcohols as a solvent, alkaline agents or A surfactant is blended, and in the second liquid, hydrogen peroxide solution is usually used as an oxidant solution for oxidizing the acid dye in the first liquid. Such a two-component type hair dye is used in a procedure in which the first liquid and the second liquid are mixed and applied to the hair, the application state is maintained for an appropriate time, and then the hair is washed off.

However, since the above-mentioned hair dye is of a two-pack type, it is troublesome to use and, in addition, since it uses an oxidizing agent, it gives a chemical damage layer to the hair, There is also a risk of rash on the scalp. Furthermore, this kind of hair dye cannot be expected to have a smoothing effect because it must be washed off by finally washing the hair.

[0004]

DESCRIPTION OF THE INVENTION The present invention does not use oxidative dyes and oxidants, and therefore does not cause excessive chemical damage to the hair or cause scalp rash, and also has a smoothing effect. A gel hair dye is provided.

That is, the hair styling agent according to the present invention is
0.2-0.3% by weight of hematein, 1.5-2.5
Wt% gallic acid, 0.1-0.15 wt% ferric chloride, 2.5-3.5 wt% green tea extract, 6.5
~ 7.5 wt% ethanol and 1.0-2.0 wt%
Of carboxyvinyl polymer and / or xanthan gum, 2.0 to 2.5% by weight of keratin polypeptide, and 0.2 to 0.5% by weight of potassium hydroxide, based on water. It is a gel-like product that does not contain other hair dressing ingredients and hair dyeing ingredients.

In the present invention, hematein used as one of the hair dyeing components is a plant pigment obtained from Indian legumes and gradually acts on a trace amount of iron contained in the hair after penetrating into the hair. To produce a black or black-brown pigment. Therefore, this hematine can be said to be a delayed-action hair dyeing component that dyes hair from inside to black.

Gallic acid, green tea extract and ferric chloride are
The gallic acid and the tannin contained in the green tea extract each act as the second hair dyeing component of the present invention and react with ferric chloride to produce a black pigment. Therefore, these second hair dyeing components exhibit the effect of quickly and externally dyeing hair. Green tea extract also contains an ingredient effective in moisturizing hair. Ethanol functions as a solvent for gallic acid and a component that enhances the dispersibility of other components when preparing the hairdressing dye of the present invention.

[0008] Carboxyvinyl polymer and / or xanthan gum and potassium hydroxide are components that hold the hair styling agent of the present invention in a gel form and give it a styling power. Keratin polypeptide is a hydrolyzate of proteins (collagen and keratin), which are the main components of hair or scalp, which penetrates into the hair or scalp to provide nutrients to the hair shaft and hair follicles, and is then peeled off. It has the function of restoring the cuticle.

The hair styling dye of the present invention comprises the above-mentioned hematein, gallic acid, green tea extract, ferric chloride, carboxyvinyl polymer and / or xanthan gum and hair dyeing ingredients and styling ingredients other than potassium hydroxide. Although it is characterized in that it is not contained, it is preferable to add an antiseptic agent or an anti-inflammatory agent which is usually used in cosmetics for hair, to this hair styling dye. Also, 1,3-butylene glycol or propylene glycol, which is effective for moisturizing hair, can be blended,
The blending amount is usually in the range of 1.5 to 2.5% by weight.

Examples of typical preservatives that can be used in the present invention include ethyl paraoxybenzoate, methyl paraoxybenzoate, phenoxyethanol, hinokitiol and the like. When compounded in an agent, the compounding amount is 0.15-0.25% by weight for ethyl paraoxybenzoate and methyl paraoxybenzoate, and 0.7-0.9% by weight for phenoxyethanol. % And hinokitiol can be selected in the range of 0.01 to 0.04% by weight.

Examples of the anti-inflammatory agent include glycyrrhizinic acid, monoammonium glycyrrhizinate, dipotassium glycyrrhizinate, cytogrethiol, licorex A, licorex Na, licorex K, licorex P, and the like. These anti-inflammatory agents can be appropriately added to the hair styling dye of the present invention depending on the purpose. For example, dipotassium glycyrrhizinate, which is preferable in terms of water solubility, is preferably contained in the hair dye composition of the present invention in an amount of 0.03 to 0.04% by weight.

[0012] Next, typical formulation examples of the hair styling agent according to the present invention will be shown below. Hematine 0.3 g Gallic acid 2.0 g Green tea extract 3.0 g Ethanol 7.0 g Ferric chloride 0.1 g Carboxyvinyl polymer-1.5 g Keratin polypeptide 2.0 g Potassium hydroxide 0.4 g Methyl paraoxybenzoate 0.2g methyl parahydroxybenzoate 0.2g dipotassium glycyrrhizinate 0.03g phenoxyethanol - Le 0.8g hinokitiol - Le 0.02 g 1,3-butylene glycolate - Le 2.0g water balance unit Total 100.0g
