Description

  The present invention relates to a hair bleaching agent composition and a hair dyeing composition, and more specifically, a hair bleaching agent composition configured as a set of a first agent and a second agent having a predetermined composition, or when these are used. A hair dye composition composed as a set of a hair bleaching agent composition mixed in step 1 and a first agent (containing a dye) having a predetermined composition and a second agent, or a dye mixture obtained by mixing these at the time of use, etc. The present invention relates to a hair composition.

  Conventionally, in an hair bleaching agent composition, ammonia is generally used as an alkaline agent to be included for promoting the action of an oxidizing agent. In this case, however, it is an irritating odor when the hair bleaching agent composition is used. An ammonia odor is generated. In order to reduce the ammonia odor, at least a part of the ammonia may be replaced with an alkanolamine such as monoethanolamine, and the amount of ammonia used may be reduced accordingly.

  On the other hand, in the hair dye composition, an alkali agent is contained for the purpose of promoting the action of the oxidizing agent and promoting the penetration of the dye into the hair. And since the kind of alkaline agent to be used is the same as in the case of the hair bleaching agent composition described above, there is still a problem of generation of ammonia odor, for the purpose of reducing the irritating odor and imparting lightness to the hair. Monoethanolamine or the like may be used as an alternative to ammonia.

  However, in such a hair bleaching agent composition or hair dye composition, the method of simply reducing the ammonia content using alkanolamine or the like ensures sufficient action of the alkaline agent and ammonia-stimulating odor. It was difficult to achieve both sufficient reduction of

Such a problem is considered to occur in the hair bleaching agent composition as well.

  Accordingly, the present invention provides a hair bleaching agent composition and a hair dyeing composition, in which the stimulating odor of the alkaline agent is satisfactorily reduced, and the hair bleaching agent composition and the hair dyeing agent are formulated with a compounding agent intended to reduce the irritating odor. The problem to be solved is to prevent the various good properties of the composition from being impaired.

  The first agent and / or the second agent are the same as in the case of the hair bleaching agent composition, and other optional components that may be incorporated in this type of composition, for example, other types of surfactant An agent, a polymer compound other than those described above, an oil component other than those described above, a solvent, and the like can be contained as necessary.

  In the second embodiment of the hair dye composition according to the present invention, the first agent and the second agent according to the first embodiment are mixed at the time of use or the like. The mixing ratio of the first agent and the second agent is not limited. For example, preferably, the first agent: second agent is in a weight ratio within the range of 1: 3 to 2: 1, and more preferably 1: 2. Can be mixed in a weight ratio in the range of ˜1: 1. In these various mixing ratios, the B / A is preferably within the range of 0.1 to 10.

  There is no limitation on the dosage form of the hair dye composition, and for example, it can be in a form known in the art such as liquid, emulsion, cream gel or foam.

〔dye〕
As the dye, an oxidation dye intermediate can be preferably used. Examples of the oxidation dye intermediate include phenylenediamines, aminophenols, toluenediamines, aminonitrophenols, diphenylamines, diaminophenylamines, N-phenylphenylenediamines, diaminopyridines and salts thereof (hydrochloric acid).

These oxidation dye intermediates may be blended alone or in combination of two or more.

  The blending amount of the oxidation dye intermediate is preferably 0.01 to 15% by weight of the first agent, and more preferably 0.1 to 10% by weight. If the blending 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.

  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.

In addition, those listed in "Quasi-drug raw material standards" (issued in June 1991, Yakuji Nippo) can be used as appropriate. These dyes may be blended singly or in combination of two or more.

  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 blending 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.

  Further, the first agent may be blended with a direct dye as a dye other than the oxidation dye intermediate and the coupler.
