[Industrial application fields]
The present invention relates to a hair bleaching agent composition and a hair dye composition, and more specifically, hair comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent, or a mixture of these in use. The present invention relates to a depigmenting agent composition and a hair dye composition comprising a first agent containing a dye and an alkali agent and a second agent containing an oxidizing agent, or a mixture of these in use.
[0002]
[Prior art]
Conventionally, this type of hair bleaching agent composition contains an alkaline agent in order to promote the action of the oxidizing agent. As the alkali agent, alkanolamine, organic amine, and the like are also used, but generally ammonia is often used. When ammonia is used as the alkaline agent, an ammonia odor that is an irritating odor is generated when the hair bleaching agent composition is used. In order to reduce the irritating odor of the hair bleaching agent composition by reducing the ammonia content by using the alkanolamine such as monoethanolamine instead of ammonia in order to reduce this irritating odor There was also.
[0003]
On the other hand, the hair dye composition is known as a two-component oxidative hair dye comprising a first agent containing a dye such as an oxidative dye intermediate and an alkali agent and a second agent containing an oxidant. Yes. The alkaline agent is added to swell the hair to facilitate the penetration of the dye and the oxidizing agent and to promote the action of the oxidizing agent. The kind of the alkaline agent used for the hair dye composition is the same as in the case of the hair bleaching composition. Therefore, as in the case of the hair bleaching agent composition, there is a problem of generation of an ammonia odor. In order to reduce the irritating odor and impart lightness to the hair, an alkanolamine such as monoethanolamine is used as an alternative to ammonia. May be used.
[0004]
The hair dye composition disclosed in Japanese Patent Application Laid-Open No. 2001-2538 uses monoisopropanolamine as an alternative to ammonia, thereby reducing the irritating odor of the hair dye composition and further containing light isoparaffin. By this, lightness is imparted to the hair.
[0005]
[Problems to be solved by the invention]
However, in the above-described conventional hair bleaching composition and hair dye composition, the method of simply reducing the ammonia content using alkanolamine or the like ensures sufficient function as an alkaline agent and ammonia. It was difficult to achieve both a sufficient reduction in pungent odor.
[0006]
In the hair dye composition disclosed in Japanese Patent Application Laid-Open No. 2001-2538, an ammonia-stimulated odor is reduced by using light isoparaffin while ensuring an effective ammonia content. In addition, the effect of decoloring hair dyeing is also improved. However, it has been found that when light isoparaffin is contained in the hair dye composition, particularly when the content is large, the feel of the hair after finishing may be deteriorated. Such a defect is considered to be the same in the hair bleaching agent composition.
[0007]
In view of the situation of the prior art described above, in the specification attached to the application of Japanese Patent Application No. 2001-297651 (unpublished) relating to the application of the present applicant, “the first agent containing an alkaline agent and the oxidizing agent are contained. The hair bleaching agent composition prepared by mixing the second agent to be used at the time of use and containing an isoparaffin and a polymer compound, and the “first agent containing a dye and an alkali agent and an oxidizing agent containing an oxidizing agent” The invention of “hair dye composition prepared by mixing two agents at the time of use and containing isoparaffin and polymer compound” is disclosed.

If the amount is less than 0.01% by weight, a sufficient hair dyeing effect cannot be obtained. If the amount exceeds 15% by weight, the hair dyeing effect is not greatly improved. Therefore, it is uneconomical to add more than 15% by weight. When it is set in the range of 0.1 to 10% by weight, both the hair dyeing effect and the economic effect can be exhibited with a good balance.
[0070]
The first agent may contain a coupler as a dye other than the oxidation dye intermediate. When a coupler is blended, the hair dyeing effect can be further enhanced.

[0071]
When said dye is mix | blended with the 1st agent, the compounding quantity is 0.01 to 10 weight% of the 1st agent, and 0.1 to 5 weight% is more preferable. If the amount is less than 0.01% by weight, a sufficient hair dyeing effect cannot be obtained. Moreover, even if it exceeds 10% by weight, the hair dyeing effect is not particularly improved, so it is uneconomical to add more than 10% by weight. When the blending amount of the dye is set in the range of 0.1 to 5% by weight, both the hair dyeing effect and the economical effect can be exhibited with a good balance.
[0072]

These direct dyes may be blended singly or in combination of two or more.
[0074]
When the direct dye is blended with the first agent, the blending amount is preferably 0.001 to 10% by weight of the first agent, and more preferably 0.01 to 5% by weight. If the blending amount is less than 0.001% by weight, a sufficient hair dyeing effect cannot be obtained. Moreover, even if it exceeds 10% by weight, the hair dyeing effect is not particularly improved, so it is uneconomical to add more than 10% by weight. When it is set in the range of 0.01 to 5% by weight, both the hair dyeing effect and the economic effect can be exhibited in a well-balanced manner.

Alkaline agent, oxidizing agent, etc.
In the hair dye composition according to the present invention, the use purpose, type, and blending amount of the alkaline agent contained in the first agent and the oxidizing agent contained in the second agent are all except for the following points. The same as in the case of the hair bleaching agent composition.
[0076]
That is, the oxidizing agent is added to oxidize a dye such as an oxidative dye intermediate in addition to the functions described above for the hair bleaching agent composition. Specific examples and blending amounts of the oxidizing agent are the same as those of the hair bleaching agent of the first embodiment. When the blending amount is less than 0.1% by weight at the time of use, melanin cannot be sufficiently decolored and the dye cannot be sufficiently oxidized. On the other hand, if it exceeds 5.0% by weight, defects such as damage are likely to occur in the hair.

That is, isoparaffin is blended to reduce the irritating odor, impart sufficient lightness to the hair, and improve the hair dyeing power. Specific examples and blending amounts of isoparaffin are the same as those of the hair bleaching agent composition of the first embodiment. If this blending amount is less than 0.05% by weight at the time of use, sufficient brightness cannot be imparted to the hair, and sufficient improvement in hair dyeing power is not observed. On the other hand, if it exceeds 8% by weight, the feel of the hair after finishing tends to deteriorate.
[0079]

About the hair dye composition and hair bleaching agent composition which concern on each said example, those 1st agents and 2nd agents were mixed by the quantitative ratio of 1: 1, and were applied to the hair | bristle bundle. Then, the viscosity and irritating odor at the time of using (mixing) the mixture, and the lightness and feel (hand) of the hair after hair dyeing or hair decoloration by the mixture were subjected to sensory evaluation. These evaluation results are shown in Tables 3 and 4.
