BRIEF DESCRIPTION OF THE DRAWING

Fig. 1 shows the principle of color development when dyeing with indigo.

DETAILED DESCRIPTION OF THE PREFERRED Embodiment

In the following, exemplary embodiments of the present invention become closer described.

The indigo plants used for the invention are not special limited, but suitable indigo plants include plants in particular of the Indigofera species, for example Polygonum tinctorium (LOUR), Strobilanthes cusina (NEES), Indigofera tinctoria and Isatis indigotica FORTUNA belong. Polygonum tinctorium LOUR is an indigo from the Polygonaceaes family, an annual plant that grows in Indonesia, China and Japan.

Strobilanthes cusina (NEES) from the Acanthaceaes family is one perennial plant that grows in China and Ryukyu.

Indigofera tinctoria from the leguminosae family is a perennial Plant that grows in India, Java and elsewhere.

Isatis indigotica FORTUNE from the Curciferaes family is an annual Plant that grows in Central Europe, China and elsewhere.

Indigo can cover the whole plant, including the root and the stem denote, but the leaves are preferred. Indigo leaves can be from the first or third harvest can be obtained, however, leaves are at their peak Growing season particularly well suited for use.

Fig. 1 shows the coloring principle when using indigo for hair coloring.

As shown in FIG. 1 is formed from indican 1 (water soluble) or glucoside contained in particular indigo leaves, an enzyme (β-glucosidase), which is found in the same plant by the hydrolysis effect, indoxyl 2 (water-soluble). In air, two molecules of this indoxyl 2 combine to form indigo 3 (not water-soluble). The hair dye that has been proposed by the inventors (Japanese Patent Publication 2001-64134) dyes the hair based on this principle.

For example, hair can be dyed by wringing the juice contained in the unprocessed indigo leaves directly onto the hair. Since the juice from unprocessed indigo leaves contains Indican 1 and an enzyme (β-glucosidase), the Indikan 1 is hydrolyzed by the enzyme (β-glucosidase) to indoxyl 2 , and then the resulting indoxyl 2 penetrates the hair, and there it is exposed to the air, it oxidizes and is associated bimolecularly, so that it becomes indigo 3 , thus enabling hair coloring.

As shown in Fig. 1, in addition to this chemical reaction, in which indican 1 (water soluble) forms indoxyl 2 (water soluble) due to the hydrolysis effect of an enzyme (β-glucosidase) which oxidizes in air, forming two indoxyl 2 molecules combine to form indigo 3 , another chemical reaction that first produces isatin 4 and then indirubin 5 .

Indirubin 5 is red-violet and the present invention has for its object to provide a hair dye and a hair coloring method using the same by producing this Indirubin 5 and thus the hair with a beautiful color based on the red-violet of the Indirubins colors.

To produce Indirubin, the hair dye must therefore (a) be a preparation contain, which is mainly a dye ingredient with indican derived from indigo contains, and (b) a preparation mainly containing the enzyme β-glucosidase contains. It is important that the hair dye is essentially no saponin or contains saponin-containing substance or, if the concentration is lower than 0.1% by weight in the entire hair dye.

In short, this means that by mixing essentially saponin-free substances or at least after mixing, the concentration in the entire hair dye does not exceed 0.1% by weight, indoxyl 2 , which is caused by hydrolysis from indican 1 caused by the enzyme (β-glucosidase) forms, oxidizes and isatin 4 , and is generated due to the oxidation-like reaction of a molecule of isatin 4 with an indoxyl 2 molecule of Indirubin 5 .

The addition of saponin or saponin-containing substances, such as, for example, saponin-containing herbal ingredients such as sapindaceae, saikati-quillaia bark and preferably sapindaceae in a concentration of 0.1% by weight or more, based on saponin in the entire hair dye, limits this entire production of Indirubin 5 , and increases the production of Indigo 3 and thus realizes hair coloring based on the Indigo (hair dye as already known from Japan's patent publication 2001-64134). Sapindaceae has long been known as a cleaning agent and foams well, so that it can be used to promote the oxidation reaction in which indoxyl 2 is bimolecularly associated during oxidation and becomes indigo 3 by increasing the surface area and increasing the supply of air.

Since the juice from unprocessed indigo leaves contains Indikan 1 and an enzyme (β-glucosidase), the above-mentioned chemical reaction takes place during storage and affects the shelf life.

The present invention is based on the finding that the above-mentioned chemical reaction during storage can be prevented by (a) processing a dye ingredient containing indican-derived indican and β-glucosidase, which is an enzyme ingredient, from an unprocessed juice Indigo leaves isolated, which contain Indikan 1 and enzyme (β-glucosidase), each make it durable and mixed for use in hair dyeing.

In the present invention, the (a) preparation already mentioned consists of which is mainly a dye ingredient with indican derived from indigo contains, from unprocessed indigo leaves, in which the β-glucosidase is deactivated, or from an indica-containing liquid extract, in which the β-glucosidase is deactivated and which is unprocessed by extraction Indigo leaves was obtained, or from a freeze-drying Liquid extract made from powder containing indica, or from one Indian-containing preparation with the above-mentioned unprocessed indigo leaves which β-glucosidase is deactivated.

Unprocessed indigo leaves or juice from unprocessed indigo leaves, the one Enzyme (β-glucosidase) can be heat treated (for example Heat treatment at a temperature of about 60 ° C to 100 ° C for about 3 minutes to 60 mm) to deactivate the enzyme β-glucosidase.

The unprocessed indigo leaves with deactivated β-glucosidase can do a lot easily by heat treatment of unprocessed indigo leaves under said conditions, steam treatment, treatment by microwaves or Drying can be obtained in the sun.

The indica-containing liquid extract with deactivated β-glucosidase can pass through an extract from unprocessed indigo leaves with lukewarm water in the above temperature range can be obtained by cooking in the said temperature range of a juice containing the enzyme (β-glucosidase) contains and from unprocessed indigo leaves by means of cold extraction Water, steam treatment or microwave treatment was obtained.

In the present invention, the (a) preparation which is mainly a Contains dye ingredient with indican derived from indigo, one by means of a publicly known method by freeze-drying said Indian-containing Liquid extract with deactivated β-glucosidase obtained from India Be powder. The execution as a powder is advantageous because the durability storage is increased and handling is simplified.

Likewise, in the present invention, the above-mentioned (a) preparation, which is mainly a dye ingredient with indican derived from indigo contains, from unprocessed indigo leaves with deactivated β-glucosidase and / or the above-mentioned liquid extract with an deactivated β-glucosidase and / or an Indian-containing preparation, in which said powder containing indica from a carrier such as starch, cellulose, Silk powder or the like is worn.

In addition, the above-mentioned preparation (a), which is mainly a Contains dye ingredient with indican derived from indigo, an indican-containing Be powder in which the above-mentioned liquid extract containing indica deactivated β-glucosidase from a carrier such as starch, cellulose, Silk powder or the like is worn and freeze-dried.

However, the preparation (b) of the present invention which is mainly the enzyme contains β-glucosidase, preferably an unprocessed juice Indigo sheets, or an indigo sheet unprocessed by freeze drying, or Juice of powder obtained from unprocessed indigo leaves with the enzyme (Β-glucosidase).

Unprocessed indigo leaves or juice from unprocessed indigo leaves can be used for said preparation (b), which mainly contains the enzyme β-glucosidase, since these contain indica 1 and enzyme (β-glucosidase).

The indican 1 contained in the unprocessed indigo leaves is only hydrolyzed by the enzyme (β-glucosidase) when the unprocessed indigo leaves are broken or crushed, so that indican 1 from the juice of unprocessed indigo leaves is easily hydrolyzed by the enzyme (β-glucosidase) can be. Therefore, freeze-drying the juice from unprocessed indigo leaves by a publicly known method and use as a powder containing enzyme (β-glucosidase) is preferred. This powder containing enzyme (β-glucosidase) does not contain water, the indicator 1 contained therein is not hydrolyzed by the enzyme (β-glucosidase), which increases the shelf life during storage.

Well-known can be used Antioxidants, such as triphenol, nordihydroguaiaretic acid, Butyl hydroxyanisole, dibutyl hydroxytoluene, propyl gallate, sodium bisulfite, Erythorbic acid, parahydroxyanisole, tea extract, apple extract or others.

In addition, an adequate amount of perfume can be added to the hair dye of the present invention. Just like the dye, it is Fragrance important to make the product attractive, to increase the market value and to cover up the unpleasant smell of the other substances.

One of the hair dyeing methods used to dye the hair according to the present Invention used is a method in which the hair dye is applied directly or evenly applied to the hair after adding water, heated, for example up to 60 ° C or more, but lower than the temperature, where the hair is damaged, heated, colored, then washed out, dried and the process is ended.

If the hair is dyed at room temperature, the light blue-violet color begins to change to a reddish purple immediately after dyeing. It is believed that the color changes to reddish violet over time because the reaction in which indoxyl 2 is oxidized and indigo 3 is generated is sluggish. Indoxyl 2 , which remains in the hair, reacts with the air and gradually oxidizes to isatin 4 , which reacts with indoxyl 2 to give indirubin 5 , since the hair dye of the present invention contains no or essentially no saponin.

If the hair is dyed at a high temperature, it can change to a reddish violet immediately after dyeing. This is believed to happen because indoxyl 2 easily converts to isatin 4 when exposed to high temperatures so that more indirubin 5 is produced. In practice it is difficult to heat the head to 60 ° C or more, preferably using a flat iron or curling iron, which is normally used to straighten wavy or curly hair.

Another hair dyeing method in which the colorant of the present Invention is used is the even application of the hair dye after Addition of a water-alcohol mixture after which the hair after Dyeing washed out, dried and the dyeing process is ended. This Method allows the hair to be colored in bluish violet to reddish violet.

The mixing ratio between water and alcohol (mass ratio) is not significantly restricted; however, a range from 90:10 to 10:90 is considered preferably referred to, the higher the alcohol content, the more reddish violet results in the final color.

The color is thought to become a reddish purple because isatin 4 does not dissolve in water, but in alcohol when indoxyl 2 converts to isatin 4 . The higher the alcohol content, the more isatin 4 and consequently indirubin 5 is produced.

Another inventive hair coloring method with a Hair dye according to the invention is a dyeing method in which a liquid mixture consists of Water, alcohol and an alkali agent is applied to the hair and thereafter the hair dye according to any one of claims 1 to 10 evenly, either directly or after adding a certain amount of water to the hair is applied. Then the hair is rinsed thoroughly, dried and the Dyeing process finished. This method makes it possible to get the hair in shades to color between bluish violet to reddish violet.

This process benefits from the fact that indoxyl 2 easily converts to isatin 4 in the alkaline range and dissolves well in alcohol. The color is expected to turn reddish purple as the production of Indirubin 5 is increased.

If here the hair dye according to the invention and the liquid mixture from water: alcohol: alkali agent are mixed simultaneously, see above However, the hair cannot be dyed because the enzyme (β-glucosidase) in the alkaline area is deactivated.

The alcohol used in the invention is not particularly limited; however, it is advantageous if a mono- or polyhydric alcohol, the number of carbon atoms of which is between 1 and 6, or a mixture of such alcohols is used, in particular methyl alcohol or ethyl alcohol, the number of carbon atoms of which is 1 or 2 , or a mixture of these is particularly advantageous.

The alkali agents used according to the invention are also no further limited; however, inorganic bases such as sodium hydroxide Magnesium hydroxide or the like, organic bases, such as ammonia, Monoethanolamine or the like, and alkali salts such as Sodium citrate, sodium phosphate or a mixture of these advantageous.
