Description

Industrial application fields

  The present invention relates to a hair dye, and more particularly to a hair dye composition that improves the flexibility, moist feeling or smoothness of hair and is excellent in dyeing fastness.

  Conventionally, two-component oxidative hair dyes comprising a first agent containing an oxidative dye intermediate and a second agent containing an oxidant have been widely used as hair dyes. In this oxidative hair dye, a colorless low molecular weight oxidative dye intermediate is infiltrated into hair, and oxidative polymerization is performed inside the hair to produce a dye and dye it. These oxidation hair dyes are very convenient because they can dye hair in various colors according to demands, and also have excellent hair dyeing power.

Problems to be solved by the invention

  However, with conventional oxidative hair dyes, the hair tends to be damaged by the hair dyeing treatment, so that the gloss and moisture of the hair disappears, the dyed color becomes unnatural and gives a strange feeling to a third party, There was a problem that the comb was bad and the hair was not supple. In order to solve these problems, a cationic polymer is often used. However, when only a cationic polymer is blended, it has a high affinity with hair, so it acts excessively and becomes irritating to the hair. It may not be enough to solve the problem.

  Accordingly, there has been a demand for the development of a hair dye that improves the gloss and flexibility of the hair and that provides a natural dyeing and sufficient fastness.

Means for solving the problem

Means for Solving the Problems The present inventor has made extensive studies in view of the above-mentioned circumstances, and as a result, has found that an amphoteric polymer acrylamide / acrylic acid / dialkyldiallylammonium chloride copolymer and a specific anionic high The present inventors have found that the above problems can be solved by combining with a molecular compound, and have completed the present invention. Hereinafter, the present invention will be described in more detail.

BEST MODE FOR CARRYING OUT THE INVENTION The hair dye composition of the present invention essentially comprises an amphoteric polymer acrylamide / acrylic acid / dialkyldiallylammonium chloride copolymer and a specific anionic polymer compound. Further, a composition containing an oxidative dye and an oxidant is an oxidative hair dye composition, and if no oxidative dye is added, it becomes a hair bleaching agent. It can also be used as a semi-permanent hair dye using only a direct dye.

Although the amphoteric polymer compound is essential for the hair dye composition of the present invention, the amphoteric polymer compound is preferably an amphoteric terpolymer acrylamide / acrylic acid / dialkyldiallylammonium chloride copolymer. Is known as Polyquaternium-39 and is commercially available as Marquat Plus 3330, 3331 (Calgon).

The amount of that from 0.05 to 10% by weight, preferably 0.1 to 5 wt%. If it is less than 0.05% by weight, a sufficient effect cannot be obtained, and if it exceeds 10% by weight, the effect is not further improved.

The anionic polymer compound comprises : ( a) a half ester of itaconic acid and polyoxyethylene alkyl ether or an ester of methacrylic acid and polyoxyethylene alkyl ether; and (b) acrylic acid, methacrylic acid and their alkyl esters. It is at least one selected from a copolymer comprising at least one monomer selected. These compounds, specifically, for example Acrylates / Ceteth-20 Itaconate Copolymer, Acrylates / Steareth-20 Itaconate Copolymer, Acrylates / Beheneth-25 Itaconate Copolymer, Acrylates / Ceteth-20Methacrylate Copolymer, Acrylates / Steareth-20 Methacrylate Copolymer or Acrylates / Beheneth-25 is known under the name of Methacrylate Copolymer.

  The blending amount can be blended within a range that does not hinder the stability of hydrogen peroxide, preferably 0.05 to 20% by weight, and particularly preferably 0.1 to 10% by weight from the economical aspect.

  When the hair dye assembly of the present invention is used as a permanent hair dye, it is usually a multi-component oxidative hair dye comprising a first agent containing an oxidizing dye and an alkaline agent and a second agent containing an oxidizing agent. It becomes a composition. And if an oxidation dye is not mix | blended with a 1st agent, it will function as a hair bleaching agent.

  The oxidation dye blended in the first agent is usually divided into a main intermediate and a coupler. Examples of the main intermediate include one or more of phenylenediamines, aminophenols, diaminopyridines, and the like and salts thereof. Examples of the salt include hydrochloride, sulfate, acetate and the like. Among these, p-phenylenediamine, toluene-2,5-diamine, N, N-bis (β-hydroxyethyl) -p-phenylenediamine, 2-β-hydroxyethyl-p-phenylenediamine, N-β-hydroxy Ethyl-N-ethyl-p-phenylenediamine, N-phenyl-p-phenylenediamine, 4,4'-diaminodiphenylamine, 2-chloro-p-phenylenediamine, N, N-dimethyl-p-phenylenediamine, p- Aminophenol, o-aminophenol, p-methylaminophenol, 2,6-dichloro-p-phenylenediamine, p-aminophenylsulfamic acid, 2,5-diaminopyridine and salts thereof are effective and hair dyeing power To preferred. The blending amount is 0.01 to 15% by weight with respect to the total weight of the first agent for hair dyeing, and if it is less than 0.01% by weight, sufficient hair dyeing effect cannot be obtained and exceeds 15% by weight. However, the effect remains the same and is not economical. Furthermore, 0.1 weight%-10 weight% are preferable, and the more superior hair dyeing effect is acquired by mix | blending 0.1 weight% or more. On the other hand, when it exceeds 10% by weight, the increase in the hair dyeing effect is reduced.

  As couplers, resorcin, pyrogallol, catechol, m-aminophenol, m-phenylenediamine, 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, phloroglucin, 2,4-diaminophenoxyethanol, gallic acid Acid, tannic acid, ethyl gallate, methyl gallate, propyl gallate, pentaploid, 1-methoxy-2-amino-4- (2-hydroxyethyl) aminobenzene, 5- (2-hydroxyethylamino) -2- Methylphenol etc. and their salts It is possible to focus. The blending amount is 0.01 to 10% by weight, and if it is less than 0.01% by weight, sufficient dyeability cannot be obtained, and even if it exceeds 10% by weight, the effect is not changed and it is not economical. Furthermore, 0.1 weight%-5 weight% is preferable, and the more outstanding dyeability is obtained by mix | blending 0.1 weight% or more. On the other hand, when it exceeds 5% by weight, the increase in dyeability is reduced. In addition, those listed in "Quasi-drug raw material standards" (issued in June 1991, Yakuji Nippo) can be used as appropriate.

  Furthermore, the hair dye of the present invention can be blended with a direct dye as a toning agent, and one or more known ones such as tar-based pigments and natural pigments can be used in combination. Among them, nitro dyes, azo dyes, nitroso dyes, triphenylmethane dyes, xanthine dyes, quinoline dyes, anthraquinone dyes or indigo dyes are preferable because they give a good hair dyeing effect, and these dyes are used as hair dyes. It is best to blend 0.01 to 10% by weight in the composition. When the amount is less than 0.01% by weight, the hair dyeing effect is insufficient. On the other hand, when the amount is more than 10% by weight, not only the hair dyeing power is not improved, but also the dyeing to the scalp and fingers is remarkable.

  Specific examples of the direct dye include nitro-p-phenylenediamine, p-nitro-O-phenylenediamine, p-nitro-m-phenylenediamine, 2-amino-4-nitrophenol, and 2-amino-5-nitrophenol. -Dye specified by the ordinance for determining tar pigments that can be used for pharmaceuticals, etc. (announced in 1966, Ministry of Health and Welfare).
