Description

Composition of colaring hair comprising extracts of logwood

The present invention relates to a hair coloring hair dye composition containing a logwood extract, and more specifically, less stimulation and dyeing duration of 1 to 2 weeks by containing a logwood extract as compared to conventional hair coloring temporary hair dye products. The present invention relates to a hair dye composition which has excellent effects and improves the protective effect of hair after dyeing by containing a hair protection component as a vegetable extract such as aloe, seaweed extract and propolis extract.

Conventionally, hair dyes, that is, hair dyes, are permanent hair dyes (oxidative hair dyes, quasi-drugs), semi-permanent hair dyes (non-oxidizing hair dyes, cosmetics), and temporary hair dyes (colorants, cosmetics) depending on the durability of the colored color and the characteristics of the composition. Can be classified as). In the case of the temporary hair dyes currently in use, the coloration is caused by pigmentation of dispersed color deposits or acidic color applied to the surface of the hair, but since it has little affinity for hair, it tends to dissolve easily in water. Due to the water drainage phenomenon, most of the dye is washed away, there is an inconvenience that must be dyed every day. In addition, since the film of the dye is thinner may be unevenly dyed, and may be stained on pillows, clothes, etc., may flow down sweat or other moisture.

Semi-permanent hair dyes, commonly referred to as acid hair dyes, are highly useful hair dyes that provide natural color close to the primary color to the hair and are stained by ionic bonding by infiltrating acid dyes into the cuticle and into the cortex. . In the case of dyes having a large molecular weight, a penetration agent of a solvent such as benzyl alcohol is blended to facilitate penetration. Molecular of non-oxidative hair dye called semi-permanent, which is a weak acid color product, called direct color as it is composed of only the first agent (cosmetics) and is called coating color or acid color. ) Do not increase the size of the pigment molecule even after penetrating the hair remains the same size. Since the hair is slightly swelled during shampooing, the hair dye molecules are washed off every time, so the dyeing power lasts up to 10-20 times of shampoo. The persistence is the porosity of the hair, the molecular size of the hair dye trapped in the hair, The alkalinity of the shampoo depends on how much the color tone of the hair can be fixed to the hair (using a pH 4 to 6.9 acid shampoo and conditioner). This hair dye does not permanently change the color of the hair. However, the hair damage is relatively small, there is an advantage that does not cause allergies and irritation on the skin, and the utilization is gradually increasing because the time taken for the procedure is short and the smell is less than that of the permanent hair dye.

In order to increase the permeability of hair with an acidic hair dye, aromatic alcohols such as benzyl alcohol, phenoxyethanol, phenylethyl alcohol, cinnamon alcohol and the like are generally used. These organic solvents are known to increase the affinity of the acid dyes to the hair by acting as a carrier to promote penetration into the hair and increase the dyeing effect. Compared with the oxidative hair dye which is a hair dye, there is a problem in that the dyeing duration is short, so that the dye should be frequently done.

The present invention is to solve the above problems and to solve the problem of the dyeing persistence of the conventional hair dyeing hair coloring conventionally used by adding a logwood which is a vegetable dye to the acid hair dyes to greatly improve the hair dyeability of the hair dyeing effect The purpose is to develop hair dye composition for coloring hair that lasts about 1-2 weeks.

The present invention relates to hair coloring containing a logwood extract comprising 0.001 to 50% by weight of hematoxylin, a logwood extract, in a hair dye composition comprising a nonionic water-soluble high molecular compound, an acidic dye, an organic solvent, and a PH regulator. It relates to a hair dye composition for. In addition, the hair dye composition of the present invention is characterized in that it additionally contains 0.001 to 20% by weight of methylpyrrolidone in 0.001 to 50% by weight of hematoxylin, a logwood extract.

The present invention is an acid hair dye composition containing a logwood extract, which is a natural dye, in an acid hair dye composition containing an acid dye and a dispersing aid. The present invention solves the problem of the dyeing sustainability of the conventional hair dye for the sachet hair coloring and by adding a logwood of the vegetable dye to the acid hair dye to greatly improve the hair dyeing effect of the sachet hair lasting about 1-2 weeks It relates to a coloring hair dye composition.

The logwood used in the hair dye composition of the present invention is a subtree of the dicotyledonous rosewood legume originated from West Indo and Central America, and the dye extracted from the heartwood of the logwood tree is represented by the following formula [1]: HAEMATOXYLIN [HAEMATOXYLIN] [ C ₁₆ H ₁₄ O ₆ ]), and has been used as a natural dye for dyeing wool, silk, cotton, and burlap to blackish brown.

The nonionic water-soluble high molecular compound used in the hair dye composition of the present invention is preferably used in an amount of 0.1 to 2% by weight, preferably 0.5 to 1.5% by weight. In the hair dye composition of the present invention, when the nonionic water-soluble polymer compound is used in an amount of 0.1 wt% or less, the viscosity is so low that there is a problem that the dispersed state of the dye precipitates over time, and when used more than 2%, the viscosity is too high. It is difficult to manufacture and inconvenient to use.

Most of the acid dyes used in the present invention belong to dyes specified in "Tar pigment designation, standards and test methods for pharmaceuticals, quasi-drugs and cosmetics" (Ministry of Health and Welfare No. 92-29). Acid dyes may be used, such as red No. 2, red No. 3, red No. 102, red No. 104, red No. 105, red No. 106, yellow No. 4, yellow No. 5, green No. 3, blue No. 1 , Blue 2, Red 201, Red 227, Orange 205, Orange 207, Yellow 202, Yellow 203, Green 201, Green 204, Red 401, Red 503, Red 504, Blue 202, blue 203, blue 205, yellow 403, yellow 406, green 401, green 402, purple 401, black 401 and the like, and these may be used alone or in combination of two or more thereof. Can be used. The amount of the acid dye used in the present invention is not particularly limited, and in general, 0.01 to 5% by weight of the whole composition is preferably used, and preferably 0.1 to 2% by weight. If the amount of acid dye used in the present invention is too small, it is difficult to expect a sufficient dyeing effect, because the higher the amount is not seen to increase the dyeing effect in proportion. Since the acid dyes used in the present invention are water-soluble and the hair surface is hydrophobic, organic solvents such as benzyl alcohol and methyl pyrolidone are used in conventional acid hair dyes and the affinity of water-soluble acid dyes for hair To increase penetration.

The acid hair dye composition of the present invention can be used within the range that does not impair the effects of the present invention, the components commonly used in acid hair dyes. For example, benzyl alcohol, methyl pyrrolidone, cinnamil alcohol, phenoxy ethanol, glycerin carbonate, propyl carbonate, etc. are mentioned as an organic solvent, These solvents are 0.5-based on the total weight of a composition. It can be used within 20% by weight.

It is preferable that the pH of the hair dye composition used in the present invention is 2.5 to 4, and the inorganic acid and organic acid may be used as the pH adjusting agent, but preferably, an organic acid is used. For example, organic acids, such as citric acid, lactic acid, glycolic acid, succinic acid, malic acid, fumaric acid, maleic acid, and inorganic acids, such as hydrochloric acid, a sulfuric acid, phosphoric acid, nitric acid, are mentioned as an organic acid. When the pH of the hair dye composition used in the present invention is lower than 2.5, skin irritation may occur, and when the pH is higher than 4.0, hair adsorption of the acid dye may be reduced. Therefore, the proper pH of the hair dye composition used in the present invention is preferably maintained at 3.0-3.6.

The acidic hair dye composition used in the present invention may be selected from the group consisting of anionic surfactants, cationic surfactants, and nonionic surfactants such as surfactants and polymers of anionic polymers, cationic polymers, nonionic polymers, and amphoteric polymers. Combined use is possible, and xanthan gum, gelatin, locust bean gum, methyl cellulose, ethyl cellulose, thickeners such as hydroxyethyl cellulose, silicone derivatives, preservatives, sunscreen, antioxidants, fragrances, etc. can be added. .
