Description

TECHNICAL FIELD The present invention relates to a hair dye composition for dyeing keratin fibers,

The present invention relates to a hair dye composition for keratin fibers, and more particularly to a hair dye composition for dyeing keratin fibers composed of two-component keratin fibers containing an oxidation dye precursor, a coupler and an alkaline agent, The present invention relates to a dyeing composition for oxidation dyeing capable of simultaneous mordting using an additive containing a metal salt.

In general, a composition for dyeing and keratinous fibers containing hair is colored by the oxidation dye precursor and the coupler penetrating into hair and binding through oxidation-condensation reaction. In the process, the alkali agent contained in the first agent promotes perhydroxy anion formation by mixing with an oxidizing agent, and they cause oxidation and melanin decomposition of the dye, .

In the composition for oxidation dyeing, in which color development occurs due to the oxidation condensation reaction, sufficient coloring was not observed in the reaction time and the penetration time of the dye into the hair within 5 minutes or less.

In order to solve the above problem, various methods have been attempted. One of them is a method in which a metal salt is pretreated (pre-mordanting) to form a complex with hair and then a dye or the like is applied to shorten a coloring time and improve a plating ability Japanese Laid-Open Publication No. 2004-2575). However, in the conventional method of pretreating a metal salt, it is inconvenient to apply the dye twice after applying the metal salt once to the hair.

Further, there is a method (JP-A-2007-320923) in which a divalent metal salt is contained in a salt hair dye composition which is used by simultaneously mixing two dyes containing a dye and a dyestuff containing an oxidizing agent to improve the dyeing power. In this case, when the metal salt is contained in the one agent, the reaction between the metal salt and the dye occurs beforehand, resulting in the discoloration of the contents and the efficiency of the reaction of the dye. 2, the metal salt is oxidized and the function of the metal salt is lost, and when the time elapses, the effect of improving the dyeing power is lost.

In addition, when the metal salt is mixed with the first and second agents simultaneously, there is a possibility that the metal salt acts as a catalyst for the hydrogen peroxide hydrolysis. In this case, the decomposition of the hydrogen peroxide water occurs rapidly and explosive oxidation and condensation reaction occurs, Only water self-decomposition occurs, or oxidation dye is reacted in advance, and hairiness is lowered in hair.

Finally, the metal salt is highly reactive and easily ionic and coordination bonds with a substance having anions or a substance having a non-covalent electron pair. If there are many kinds of materials having negative and non-covalent electron pairs in the composition, a competitive reaction occurs and it is difficult to realize a desired color, and it becomes difficult to bond with hair, and dyeability and colorability are deteriorated.

Accordingly, the present inventors have found that, in order to solve the conventional problems as described above, the antimicrobial and antioxidant agents which do not undergo coordination or ionic bonding with the metal salt in the dyeing composition for oxidation dyeing, And controlling the reaction of the metal salt and the oxidizing agent without controlling the oxidation and condensation reaction of the dye effectively controls the mordanting reaction of the metal salt, the dye and the hair to improve the durability and the dyeing speed. Thus, the present invention has been completed .

Accordingly, it is an object of the present invention to provide a composition for dyeing and keratin fibers which has enhanced dyeing ability and short coloring time while shortening the reaction time.

In order to achieve the above object, the present invention provides a hair dye composition for dyeing keratin fibers consisting of two components, which comprises an oxidation dye precursor, a coupler and an alkaline agent, 1 < / RTI > and 2 < RTI ID = 0.0 > agents. ≪ / RTI >

There is no particular limitation, and water or an organic solvent may be used.

The preferred methods of extracting the above plants are as follows.

The obovate extract is washed with purified water to remove minute dust and the like, and then the foreign material is removed with purified water using 250 mesh. After drying at 50 ° C for 24 hours, the mixture was immersed in 5 times 50% butylene glycol aqueous solution with respect to the weight of dwarf and subjected to extraction at 50 ° C for 6 hours.

After drying at 50 DEG C for 48 hours, 50 kg of dried persimmon and persimmon leaves are mixed with 250 kg of 50% ethanol (EtOH) and heated at 60 DEG C for 3 to 5 hours to extract. The foreign matter is removed by using 250 mesh and centrifugation, filtered with a filter paper of 0.5 μm, and treated with activated carbon to remove the color and odor of the extract. After filtration through filter paper of 3 탆, 1 탆, and 0.5 탆 on a third order, a butenol glycol solvent may be added to prepare a persimmon extract.

Extracts and gum dyes such as black tea, squash, chestnut (night), oak, balonie, mangrove, oak (bark), mimosa (wattle), keppaco and gambia can be produced in the same manner as green tea extract .

Although tannins are aromatic compounds having a large number of phenolic hydroxyl groups and some of the components are separated into crystalline phases as a single substance, most of the products are mixed with several kinds of substances and are obtained as white or pale brown amorphous powders. When chemically speaking, it refers to its main component. There are two representative taxonomy types. One is a method in which a hydrolyzable tannin which is hydrolyzed by heating with dilute acid to produce gallic acid or eragic acid and a condensed tannin which is polymerized to produce a red or brown precipitate, Is a method of dividing into a pyrogallol system which mainly produces pyrogallol by alkali fusion and a catechol system which mainly generates catechol and an intermediate thereof. It is called eraditanine that producing galactan and eragic acid mainly produce galactan when hydrolyzed. Many of them are composed of sugars (usually glucose) and esters of one or several phenolcarboxylic acids, and hydrolysis is also carried out by alkaline or oxygenated tanacase or Takagiastase. The pyrogallol tannins include dwarf and worm, as well as tannins such as persimmon (fruit, leaf), squash, chestnut (chestnut), oak tree and balonie, and are generally highly astringent. It is turned blue by iron white solution and turns black. In addition, Bromine does not produce precipitate, but it becomes blue by limestone. On the other hand, the catechol system contains tannins such as tea leaves (green tea, black tea), mangrove, oak (bark), mimosa (watt), keppaco and gambia. In addition, it turns green after being ironed by black iron, and it is precipitated by the number of bromine and does not develop color by limestone. The distribution in the plant system is very broad and is generally found in less ripe fruits and seeds and tends to decrease with maturity. This suggests that tannin is metabolizable, but its physiological function is not known. It is most widely used as a dermatological agent, and is also used as a dyestuff dyeing and ink manufacturing and medicines for fishing net. In addition, it can be used as a raw material for adhesives, a capillary for boiler, antifoaming agent for metal surface, The use of the field is pioneering. In Korea, imported tannin extracts are mainly used. In addition to the dyestuffs, the production of blue black ink by reacting with iron (Ⅲ) salt to change blue color, and the production of colored precipitates by reaction with metal ions, , Galantanin purified tannic acid is astringent and hemostatic agent, tannin albumin combined with egg white and tannic acid is a dressing agent.
