Description

  The present invention relates to a hair bleaching agent composition and a hair dye composition that can reduce irritating odors and give good lightness to hair.

  Conventionally, this type of hair bleaching agent composition contains an alkaline agent for promoting the action of an oxidizing agent. Specific examples of the alkali agent include ammonia, alkanolamines, organic amines, etc., but ammonia is generally used. For this reason, in order to reduce the irritating odor of the hair bleaching agent composition based on ammonia, monoethanolamine may be contained instead of ammonia. And by reducing the content of ammonia, the irritating odor of the hair bleaching agent composition is reduced, and lightness is imparted to the hair bleaching agent composition.

  On the other hand, the hair dye composition is known as a two-component oxidative hair dye composed of a first agent containing an oxidative dye intermediate and an alkali agent as a dye and a second agent containing an oxidant. . The alkaline agent is added to swell the hair so that the dye and the oxidizing agent can easily penetrate into the hair and promote the action of the oxidizing agent. Specific examples of the alkaline agent include those described in the hair bleaching agent composition, but ammonia is generally used in the same manner as the hair bleaching agent composition. For this reason, in order to reduce the irritating odor of the hair dye composition based on the ammonia odor, monoethanolamine may be contained as a substitute for ammonia in the same manner as the hair bleaching composition. And by reducing the content of ammonia, the irritating odor of the hair dye composition is reduced, and lightness is imparted to the hair.

Further, in a hair dye composition using monoethanolamine for reducing the irritating odor of ammonia, a cationic polymer compound may be contained for improving touch. (For example, refer to Patent Document 1.)

Examples of the coupler include resorcin, pyrogallol, catechol, m-aminophenol, m-phenylenediamine, o-aminophenol, 2,4-diaminophenol, 1,2,4-benzenetriol, toluene-3,4- Diamine, toluene-2,4-diamine, hydroquinone, α-naphthol, 2,6-diaminopyridine, 1,5-dihydroxynaphthalene, 5-amino-o-cresol, diphenylamine, p-methylaminophenol, 2,4- Examples include diaminophenoxyethanol, gallic acid, tannic acid, ethyl gallate, methyl gallate, propyl gallate, pentaploid, 5- (2-hydroxyethylamino) -2-methylphenol, and salts thereof. 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 mix | blending said dye with the 1st agent, the compounding quantity is 0.01-10 mass% in the density | concentration at the time of use, and 0.1-5 mass% is more preferable. When the amount is less than 0.01% by mass, a sufficient hair dyeing effect cannot be obtained. Moreover, even if it exceeds 10 mass%, since the hair dyeing effect does not improve greatly especially, it is uneconomical to mix exceeding 10 mass%. When it is set in the range of 0.1 to 5% by mass, both the hair dyeing effect and the economic effect can be exhibited with a good balance.

  Furthermore, you may mix | blend a direct dye with the 1st agent as dyes other than an oxidation dye intermediate body and a coupler. When a direct dye is blended, the hair dyeing effect can be further enhanced. Examples of the direct dye include 4-nitro-m-phenylenediamine, 4-nitro-o-phenylenediamine, 2-nitro-p-phenylenediamine, picramic acid, 1-amino-4-methylanthraquinone, 1,4 -Diaminoanthraquinone, 2-amino-4-nitrophenol, 2-amino-5-nitrophenol and their salts, and "Ministerial ordinance for determining tar dyes that can be used in pharmaceuticals" (1960 notification, Ministry of Health and Welfare) ) And acid-soluble dyes and oil-soluble dyes.

These direct dyes may be blended singly or in combination of two or more.

  When the direct dye is blended with the first agent, the blending amount is preferably 0.001 to 10% by mass, more preferably 0.01 to 5% by mass in terms of the concentration at the time of use. If the blending amount is less than 0.001% by mass, a sufficient hair dyeing effect cannot be obtained. Moreover, even if it exceeds 10 mass%, since the hair dyeing effect does not improve greatly especially, it is uneconomical to mix exceeding 10 mass%. When set in the range of 0.01 to 5% by mass, both the hair dyeing effect and the economic effect can be exhibited in a well-balanced manner.

  Ammonia is added to swell the hair to facilitate penetration of the dye and the oxidant into the hair and to promote the action of the oxidant. The compounding amount of ammonia is the same as that of the hair bleaching agent composition of the first embodiment. In addition, the amount of ammonia when converted to 28% by mass of ammonia water cannot sufficiently swell the hair if the concentration at the time of use is less than 1.0% by mass. There is a possibility that it cannot be promoted. On the other hand, if it exceeds 3.5% by mass, the irritating odor of the hair dye composition may not be reduced.

  Alkanolamine is added as a substitute for ammonia to reduce the irritating odor of the hair dye composition, swell the hair and make it easier for the dye and the oxidant to penetrate into the hair, and further the action of the oxidant. Formulated to impart lightness to the hair by promoting. Specific examples and blending amounts of alkanolamine are the same as those in the hair bleaching agent composition of the first embodiment. In addition, if the compounding quantity of alkanolamine is less than 1.0 mass% in the density | concentration at the time of use, while not being able to swell hair, there exists a possibility that the effect | action of an oxidizing agent cannot be accelerated | stimulated. On the other hand, when it exceeds 6.0 mass%, when flowing the hair dyeing solution after hair dyeing, there is a risk that the hair will become wrinkled or squeaky. In addition, after drying, there is a risk that the feel of the hair will become wrinkled or the combing will be poor. Moreover, if hair dyeing is repeated continuously, there is a risk that the hair becomes wrinkled and the comb-like badness increases.

  The oxidizing agent is blended for decolorizing melanin contained in hair and oxidizing a dye such as an oxidation dye intermediate. Specific examples and blending amounts of the oxidizing agent are the same as those of the hair bleaching agent composition of the first embodiment. If the blending amount is less than 0.1% by mass 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 mass, defects such as damage are likely to occur in the hair.

  Component (A) is blended in order to reduce the pungent odor of ammonia, impart good lightness to the hair, improve the feel of the hair, and obtain good dyeability. The compounding quantity of a component (A) is the same as the hair bleaching agent composition of 1st Embodiment. If the blending amount is less than 0.01% by mass at the time of use, a sufficient effect may not be obtained, and even if it exceeds 1.5% by mass, the effect does not change and is not economical.

  A component (B) is mix | blended in order to make the feel of hair favorable. The compounding quantity of a component (B) is the same as the hair bleaching agent composition of 1st Embodiment.

  A component (C) can be further blended in the hair dye composition of this embodiment. By mix | blending a component (C), while being able to prevent dripping after apply | coating to hair, more favorable brightness can be provided and dyeing | staining property can be improved. The specific example and the compounding quantity of a component (C) are the same as the hair bleaching agent composition of 1st Embodiment. If the blending amount is less than 0.1% by mass at the time of use, there is a risk of dripping due to a decrease in viscosity after application to the hair, and if it exceeds 10% by mass, no further effect can be obtained and it is economical. is not.

  A component (D) can further be mix | blended with the hair dye composition of this embodiment. By blending component (D), the irritating odor can be further reduced. The specific example and compounding quantity of a component (D) are the same as the hair bleaching agent composition of 1st Embodiment. If the blending amount is less than 0.1% by mass at the time of use, a sufficient effect cannot be obtained, and even if it exceeds 25% by mass, no further effect is obtained and it is not economical.

  The hair dye composition of the second embodiment may be blended with the components listed in the first embodiment as other additive components. The compounding amount of the other additive components is determined according to a conventional method of the hair dye composition.

According to the second embodiment described in detail above, the following effects are exhibited.
-In the hair dye composition of 2nd Embodiment, since it contains a component (A) and a component (B), while reducing the irritating odor of ammonia and giving favorable lightness to hair, the touch of hair And good dyeability can be obtained.
-Furthermore, by containing a component (C), while being able to prevent dripping after apply | coating to hair, favorable lightness can be provided with hair and dyeing | staining property can be improved.
-Furthermore, an irritating odor can be reduced more by containing a component (D).
