Description

Composition for the oxidative dyeing containing gallic acid or gallate derivatives}

The present invention relates to a hair dye composition for oxidative dyeing of keratin fibers containing a molar asset or an ester derivative thereof. More specifically, in the oxidation dyeing hair dye comprising a first agent containing an oxidizing dye precursor and a coupler and a second agent containing an oxidizing agent, the first agent contains a molar asset or an ester derivative thereof as an antioxidant, There is little hair damage and promotes discoloration of hair and penetration of dye into the hair, which leads to rapid color development, as well as to reduce hair stains due to the time difference during treatment, thereby enabling uniform color development.

In general, the composition for oxidative dyeing of keratin fibers, including hair, is composed of one agent containing an oxidized dye precursor and a coupler and two agents containing hydrogen peroxide, and the oxidation condensation reaction is performed between the dyes through mixing before use. In the reaction, the perhydroxy anion of the oxidant acts to oxidize and degrade the melanin of the dye (Scheme 1), but reacts with the oxidant itself as an unwanted side reaction to form a radical (Scheme 2). Sudden self-decomposition leads to a decrease in oxidant efficiency and premature oxidative condensation reaction before dye penetration into the hair, resulting in insufficient color development, and degrading the hair protein resulting in hair damage.

In order to solve the above problem, ascorbic acid, erythorbic acid, tertiary butyl hydroquinone, tocopherols and the like are commonly used as antioxidants, which stabilize the active radicals by giving off the active hydrogen atoms of the antioxidant molecule itself. It becomes a compound, which itself becomes a less active radical and then turns into a stable compound by interaction with other radicals (Scheme 3). The result is a significant reduction in the number of active radicals, which results in suppressing the chain reaction.

However, ascorbic acid and erythorbic acid, which are commonly used in hair dyes, are less active than phenolic antioxidants, and tocopherols and tertiarybutylhydroquinone, which are phenolic antioxidants, are fat-soluble and mainly used in the water phase. It has little effect on the oxidation reaction of the dye in which the reaction takes place.

Accordingly, Japanese Patent Application No. 1994-128380 'Hair Treatment Agent' discloses various antioxidants such as butylhydroxyanisole, dibutylhydroxytoluene, and molar esters in addition to the antioxidants commonly used in the conventional hair dyes. However, it focuses on the efficacy of hair treatment agents that use antioxidants and cellulose derivatives that can be used universally, rather than the efficacy of specific antioxidants, and also hair dyes containing oxidants, unlike hair dyes 1, which is added with a reducing agent. By containing in the agent there is a fear that the efficacy as an antioxidant mentioned above due to the self-oxidation over time when stored.

On the other hand, Japanese Patent Application No. 2005-179191 `` semi-permanent hair dye composition '' describes a technique for containing a semi-permanent hair dye composition containing a direct dye having a nitro group, containing a molar asset, its ester, vitamin E, etc. LE is simply used to improve the storage stability of the dye directly.

In addition, Japanese Patent Application No. 1995-165542 discloses a hair dye composition containing a compound such as pyrogarol, a molar asset or ester thereof, iron salt and silicone oil, and Japanese Patent Application No. 1993-170629 which contains iron salt. A hair dye composition comprising a first agent and a second agent comprising a compound such as a phosphate propyl, ascorbic acid oil, and the like are described. However, the above techniques are only those technologies in which pyrogarol, a molar asset, or an ester thereof acts as a substitute for an oxidative dye, not affecting the final coloration by acting on the reaction itself of the oxidizing dye.

Therefore, the present inventors have studied to solve the above problems, when the hair dye agent in the dyeing agent for oxidation dyes as an antioxidant that can effectively inhibit the formation of radicals, when the molar property or ester derivatives thereof is less hair damage The present invention has been accomplished by promoting the decolorization of the hair and the penetration of the dye into the hair, thereby achieving a color development in a short time, and reducing the stain of the hair due to the time difference during the dyeing process.

Accordingly, it is an object of the present invention to provide a hair dye composition for oxidation dyeing which contains a molar asset or an ester derivative thereof as an antioxidant.

In order to achieve the above object, the dyeing agent composition for oxidation dyeing according to the present invention is characterized in that it contains 0.01 to 5% by weight relative to the total weight of the composition or ester derivatives thereof.

Hereinafter, the present invention will be described in more detail.

The dyeing agent composition for oxidation dyeing according to the present invention comprises a first agent containing an oxidizing dye precursor and a coupler and a second agent containing an oxidizing agent, wherein the first agent contains a molar property or an ester derivative thereof to prevent hair damage. Color development takes place in a short time, and enables uniform color development.

In the present invention, the molar compound or its ester derivative is a phenolic antioxidant and a phenolic antioxidant, butylhydroxyanisole, dibutylhydroxytoluene, tertiary, unlike conventional ascorbic acid, erythorbic acid and salts thereof. Compared to butylhydroquinone and tocopherols, it has higher solubility in water, which can effectively inhibit the chain reaction caused by radicals in the oxidation reaction of the dye which is the main reaction in the water phase, thereby preventing hair damage caused by radicals.
