Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair dye composition which is excellent in hair bleaching power, has less pungent odor, and has a good finish of hair.

[0002]

2. Description of the Related Art Oxidative hair dyes are dyes that allow an oxidation dye to penetrate into the hair and cause oxidative polymerization in the hair to produce a dye and dye it. In general, such a hair dye comprises a first agent mainly containing an oxidation dye intermediate such as paraphenylenediamine and a second agent mainly containing an oxidizing agent such as hydrogen peroxide. The above two agents are mixed and used for hair dyeing. The composition in which the oxidation dye is not blended in the first agent is a hair bleaching agent composition.

[0003] The first agent is usually adjusted to be alkaline by blending an alkali agent. This alkaline agent makes the mixture of the first and second agents usually have a pH of about 9 to 10 to moisturize the hair and facilitate the penetration of the oxidative dye intermediate into the hair. Is essential to promote the release of oxygen. The nascent oxygen oxidizes the oxidation dye intermediate to produce a colored substance, and also serves to degrade melanin and decolorize the hair. That is, this type of hair dye can be dyed as a whole in a desired color by dyeing the black hair of the hair mixed with white hair while bleaching.

[0004] Therefore, in addition to the ability to oxidize the dye, the ability to bleach black hair is essential for these hair dyes.

As these alkaline agents, ammonia is mainly used, and in addition, for example, monoethylamine,
Organic amines such as alkylamines such as diethylamine and triethylamine, or alkanolamines such as monoethanolamine, sodium hydroxide, potassium hydroxide and carbonates are used.

[0006]

Generally, ammonia water is widely used as an alkaline agent, but this is preferable in terms of chemical action, and provides sufficient hair dyeing and bleaching power as well as the texture of hair. Although it is good, the conventional compounding amount is accompanied by a pungent odor and may give a user discomfort. In addition, even when a certain amount or more is added, only a strong irritating odor and irritation to the scalp are increased, and no remarkable increase in hair dyeing power and bleaching power is observed. Alkylamines and alkanolamines have a low irritating odor, but they must be used in large amounts in order to exhibit the hair dyeing and bleaching effects. Or give off the finish of the hair. With other alkaline agents, oxygen during the nascent period cannot be released effectively from the oxidizing agent, and hair cannot be dyed or bleached sufficiently.

[0007] Also, the use of ammonia water with monoethanolamine, ammonium carbonate or the like has been studied. Monoethanolamine or ammonium carbonate is effective for sufficiently reducing the irritating smell of ammonia and obtaining sufficient hair dyeing and bleaching powers, but it gives the hair a stiffness and gives a finished texture. It would have made it worse. The effect became remarkable with continued use, and it was required to improve the texture of the finished hair.

An object of the present invention is to solve the above-mentioned problems, and it is an object of the present invention to provide a hair dye composition having less irritating odor, excellent bleaching effect, and excellent hair finish. .

[0009]

The inventors of the present invention have conducted intensive studies. As a result, by replacing a part of the aqueous ammonia used with an alkali metal carbonate, the irritating odor of ammonia can be suppressed and monoethanolamine or carbonate It has been found that a hair dye composition which can not be achieved by the use of ammonium or the like but can also improve the texture of the finished hair and has a sufficient bleaching power can be obtained.

That is, the gist of the present invention is to provide a first hair dye composition which contains an alkali agent and is mixed with a second agent containing an oxidizing agent at the time of use. And 28% ammonia water and carbonate in a ratio of 0.5: 1 to 1: 1.
A hair dye composition characterized by being blended at a weight ratio of 0: 1 and having a pH adjusted to 9.5 to 12.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION The amount of ammonia used in the present invention is as follows.
Preferably, the content is less than 1% by weight.
If the dyeing effect or bleaching effect is not sufficient, and if it exceeds 10% by weight, the irritating odor starts to increase, and the scalp and hair tend to be damaged.

Examples of the alkali metal carbonate include potassium carbonate, potassium bicarbonate, sodium carbonate and sodium bicarbonate, and one or more selected from these are used. The compounding amount is preferably 0.1 to 5% by weight of the first agent. If the amount is less than 0.1% by weight, the amount of ammonia cannot be effectively reduced in order to obtain a hair dye composition having a constant bleaching power. No effect can be expected.

Further, when the mixing ratio of suppressing the ammonia-irritating odor and having excellent texture of the hair finish was examined, 28% ammonia water and carbonate were added in a ratio of 0.5: 1 to 10:
It has been found that good results can be obtained by blending at a weight ratio of 1. Outside of this range, the pungent odor may become too strong or the hair texture may be impaired.

In general, a hair dye is filled in a glass bottle or a plastic bottle if it is in a liquid state, or is filled in an aluminum tube whose inner surface is coated in a cream state. The aerosol hair dye is charged together with the propellant gas into a metal can such as aluminum or tin coated on the inner surface. However, compared to conventional hair dyes, the hair dyes of the present invention that use ammonia and carbonate in combination are susceptible to corrosion of the above-mentioned ordinary metal tubes and cans for unknown reasons, and may cause expansion or rupture of the container. It turned out that it could be the cause. In order to solve such a phenomenon, the mixing ratio of the alkaline agent was examined. As a result, considering the effect of suppressing the above-mentioned ammonia-stimulated odor and the excellent texture of the finished hair, 28% ammonia water and carbonate were added in an amount of 1%. : When blended at a weight ratio of 1 to 5: 1,
We found that corrosion of metal tubes and cans was relatively unlikely. However, in order to stably store the hair dye composition of the present invention, it is preferable that the hair dye composition is filled in a glass container or a plastic container if possible. Also, a metal container can be filled by using a plastic inner bag.

[0015] The plastic materials used for these include polyethylene, polypropylene, polyethylene terephthalate, polyethylene naphthalate, polyacrylonitrile, ethylene-vinyl alcohol copolymer,
Examples thereof include a single layer of ethylene-vinyl acetate copolymer, ionomer resin, epoxyphenol and vinyl chloride, or a material composed of a laminate of two or more of them. Among them, from the viewpoint of the barrier performance of the hair dye, polyethylene, polypropylene, polyethylene terephthalate, polyethylene naphthalate, ethylene-vinyl alcohol copolymer, ethylene-vinyl acetate copolymer, ionomer resin and a single layer of epoxyphenol or Materials consisting of two or more layers are preferred.

The total amount of the ammonia and the carbonate is preferably adjusted so that the pH of the first agent is 9.5 to 12. In this pH range, an excellent bleaching effect can be obtained with a relatively small amount of ammonia.

The hair dye composition of the present invention may be a liquid, an emulsion,
It can be applied to all generally known dosage forms such as cream, gel and aerosol mousse.
In particular, the excellent bleaching effect of the present invention is remarkable in an aerosol mousse-like hair dye composition. Conventional aerosol mousse hair dyes using ammonia as an alkaline agent, when discharged in a mousse form, the surface area of the drug becomes very large, and the effect of the propellant gas is added to make it easier for ammonia to volatilize, causing a pungent odor. However, it was difficult to obtain a sufficient bleaching effect and a hair dyeing effect because the strength was increased and the alkali content was reduced accordingly. On the other hand, the present invention can provide a hair dye having less irritating odor and excellent bleaching power, because the amount of ammonia is smaller than before and the non-volatile alkali metal carbonate supports the bleaching power. It is considered possible.

There is also a technique in which monoethanolamine or ammonium carbonate is used in combination as a non-volatile alkali, but monoethanolamine or ammonium carbonate impairs the finish of hair and is not preferred. The present invention has also solved this problem and can provide a good finish.

The hair dye composition of the present invention may contain components usually used in hair dyes.
