Description

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

More particularly, the present invention relates to a hair dye composition for dyeing oxidation, which comprises a first agent containing an oxidation dye precursor, a coupler and an alkaline agent, and a second agent containing an oxidizing agent, The present invention relates to a hair dye composition which simultaneously contains a buffer and a nonionic polymer film former, and is capable of reducing hair damage while alleviating dyes during use, and alleviating irritating odors and scalp irritation.

In general, the composition for hair oxidation dyeing is composed of a first agent containing a dye such as an oxidation dye precursor, a coupler and an alkaline agent, and a second agent containing an oxidizing agent. In order to accelerate the action of the oxidizing agent, an alkaline agent is contained in the composition for hair dyeing of this kind, and alkanolamine, organic amine and the like are also used as an alkaline agent, but ammonia is generally used in many cases.

However, when ammonia is used as an alkaline agent, irritating odor due to ammonia and scalp stimulation and hair damage due to high pH of 1 agent are exhibited. Therefore, in order to reduce such irritating odor, alkanolamine such as ethanolamine is used and the content of ammonia is decreased to suppress the irritating odor of the hair dyeing composition. However, it is difficult to obtain sufficient action of the alkaline agent have.

For example, Patent Application No. 10-2003-0017682 discloses a method for improving the masking effect on a substance such as ammonia and a method of forming a hair color stable in an alkaline solution or an acidic solution And Japanese Patent Application No. 2003-221319 discloses that a nonionic surfactant, a cationic or amphoteric polymer compound, isoparaffin and the like are mixed and used to improve irritation and hair feel. Japanese Patent Publication No. 2005-232075 discloses a buffer composition using component A selected from at least one selected from ascorbic acid and salts thereof, and component B selected from at least one of ammonium phosphate and salts thereof , All of which have the drawback that the effect is insufficient.

Accordingly, the present inventors have conducted studies to solve the conventional problems as described above. As a result, they found that when a buffer and a nonionic polymer film forming agent are used together with a hair dye composition for dyeing with oxidation using ammonia as an alkaline agent, Stimulation and hair damage can be effectively alleviated and the present invention has been completed.

Accordingly, an object of the present invention is to provide a hair dye composition for dyeing with oxidation that effectively alleviates irritating odors, scalp stimulation, and hair damage while maintaining dyeability at the time of use.

In order to achieve the above object, the present invention provides a hair dye composition for dyeing oxidation comprising a first agent containing an oxidation dye precursor, a coupler and an alkaline agent, and a second agent containing an oxidizing agent, And a polymer film former. The present invention also provides a hair dye composition for dyeing with oxidation.

In the composition, the buffer is contained in an amount of 0.1 to 10% by weight based on the total weight of the first composition, and the nonionic polymer film is preferably contained in an amount of 0.1 to 10% by weight based on the total weight of the first composition.

The hair dye composition for dyeing with oxidative dye containing a buffer and a polymer film forming agent according to the present invention contains a buffer and a polymer film forming agent at the same time to maintain dyeability at the time of use and to reduce hair damage and reduce irritation and scalp irritation have.

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

The hair dye composition for dyeing with oxidation according to the present invention is characterized in that it comprises a first agent containing an oxidation dye precursor, a coupler and an alkaline agent, and a second agent containing an oxidizing agent, wherein the first agent is buffered and non- And a polymer film former.

The buffer included in the first agent includes at least one buffer selected from ammonium chloride, ammonium carbonate, ammonium sulfate, ammonium nitrate, and ammonium salt, 10% by weight, preferably 1 to 5% by weight. If the content of the buffer is less than 0.1% by weight, hair damage, scalp irritation and irritation may not be effectively reduced. If the content of the buffer is more than 10% by weight, hair dye formulation may be difficult.

Next, the nonionic polymer film forming agent included in the first agent together with the buffer acts to suppress the irritation of ammonia and form a polymer film on the surface of the hair to alleviate hair damage and irritation. Specific examples thereof include vinylpyrrolidone, vinyl acetate, homopolymers of dimethylamino methacrylate, vinylpyrrolidone / vinyl acetate copolymers, vinyl acetate / dimethylamino methacrylate copolymers, and the like. Based on the total weight of the first composition, 0.1 to 10% by weight, preferably 1 to 5% by weight. If the polymer film-forming agent is less than 0.1% by weight, the above effects can not be sufficiently exhibited. If the amount is more than 10% by weight, it is difficult to formulate the polymer film-forming agent.

Further, the hair dye composition for dyeing oxidation of the present invention can be used in a neutral to alkaline pH range, and is preferably used under alkaline conditions. For this purpose, the first agent includes an alkali agent, and examples of the alkali agent used herein include alkali agents such as ammonia, monoethanolamine, triethanolamine, aminomethylpropanol, isopropanolamine, sodium hydroxide, It can be supplementarily used within a range not to deteriorate the effect of the invention.

Further, the dyeing composition for dyeing oxidation of the present invention contains a conventional oxidation dye precursor and a coupler, preferably two or more oxidation dye precursors and couplers, and is not particularly limited in its kind . Examples of such oxidative dye precursors include o-aminophenol, p-aminophenol, toluene-2,5-diamine hydrochloride, p-phenylenediamine hydrochloride, toluene-2,5-diamine, p- -Methylaminophenol, sulfuric acid-o-aminophenol, p-aminophenol sulfate, toluene-2,5-diamine sulfate and p-phenylenediamine sulfate. Examples of the coupler include 2-methyl-5-hydroxyethylaminophenol, p-amino-ocresol, m-aminophenol, 2,4-diaminophenoxyethanol hydrochloride, m- Phenylenediamine,? -Naphthol, resorcinol, 2-methylresorcinol and the like can be used.

In addition, the hair dye composition for dyeing keratin fibers of the present invention can be used within a range that does not impair the effect of the present invention. For example, antioxidants, metal sequestrants, solvents, surfactants, thickeners, perfumes, and conditioning agents are used, but they are not particularly limited as they can be commonly used in hair dyeing agents.

Meanwhile, the oxidizing agent contained in the second agent of the hair dye composition for dyeing keratin fibers according to the present invention is selected from hydrogen peroxide, peroxide element, alkali metal bromate, pericyanide, perborate, persulfate and the like One or more of them may be used, but hydrogen peroxide is particularly preferably used.

The hair dye composition for dyeing keratin fibers of the present invention is applied to hair by mixing the first agent and the second agent immediately before dyeing.
