Description

  The present invention relates to a hair dye composition, and more particularly to a hair dye composition having excellent light resistance and dyeing.

  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 hair dye, a colorless low molecular weight oxidative dye intermediate is infiltrated into hair, and oxidative polymerization is carried out in the hair to form a pigment and dye the hair. These hair dyes are capable of dyeing hair in various colors according to demands, and are very convenient because of their excellent hair dyeing power, and have been widely used.

However, when the above-mentioned oxidative hair dye is used, there are drawbacks that fading is observed by sunlight, and an unnatural dyeing is realized so that a third person can know that the hair has been dyed.
The object of the present invention is to solve the above problems and to provide a hair dye composition excellent in light resistance and dyeing.

  As described above, the hair dye composition of the present invention is excellent in light resistance and dyeing.

Hereinafter, the configuration of the present invention will be described in detail.
In the present invention, N, N-bis (2-hydroxyethyl) -p-phenylenediamine and a salt thereof are used as the component (a). (A) The compounding amount of the group component is 0.01 to 15% by weight, and if it is less than 0.01% by weight, a sufficient hair dyeing effect cannot be obtained. Not economical.

  In addition, about the minimum of a compounding quantity, 0.1 weight% is preferable and the more superior hair dyeing effect is acquired by mix | blending 0.1 weight% or more. The upper limit is preferably 10% by weight, and if it exceeds 10% by weight, the increase in the hair dyeing effect is reduced.

By containing p-phenylenediamine or a salt thereof as the (b) group component together with the (a) group component, light resistance and dyeing can be improved. (B) The compounding amount of the group component is 0.01 to 10% by weight, and if it is less than 0.01% by weight, sufficient light resistance and dyeing cannot be obtained. It is not economical. In addition, about the minimum of a compounding quantity, 0.1 weight% is preferable and the more outstanding light resistance and dyeing-up are obtained by mix | blending 0.1 weight% or more. The upper limit is preferably 5% by weight, and if it exceeds 5% by weight, the increase in light resistance and dyeing is small.

Furthermore, light resistance and dyeing-up can be improved by containing p-aminophenol or a salt thereof and resorcin or a salt thereof as the (c) group component. The amount of that is 0.01 to 10 wt%, less and no sufficient light resistance and Someagari is obtained than 0.01 wt%, economical exceeds 10 wt%, unchanged its effect is not. In addition, about the minimum of a compounding quantity, 0.1 weight% is preferable and the more outstanding light resistance and dyeing-up are obtained by mix | blending 0.1 weight% or more. The upper limit is preferably 5% by weight, and if it exceeds 5% by weight, the increase in light resistance and dyeing is small. In addition, as the salt of the group component (a) to (c), for example, a salt of an organic acid or a salt of an inorganic acid, that is, sulfate, hydrochloride, phosphate, acetate, propionate, lactate, Examples thereof include citrate.

  When the weight ratio of the (a) group component, (b) group component, and (c) group component is a: b: c = 1: 0.01 to 0.5: 0.01 to 5, more excellent light resistance Sex and dyeing are obtained. Furthermore, the range of a: b: c = 1: 0.02-0.3: 0.01-5 is more preferable in terms of light resistance and dyeing, and a: b: c = 1: 0.03-0.18. : The range of 0.01-5 is still more preferable at the point of light resistance and dyeing.

  Furthermore, when a higher alcohol and / or hydrocarbon is added as a component (d), stability, hair dyeing operability (for example, ease of application to hair, no dripping, ease of mixing operation, etc.), dyeing The effect which was excellent in the point of property and fastness is acquired. The blending amount is 3 to 30% by weight, and if it is less than 3% by weight, sufficient stability, hair dyeing operability, dyeability and fastness cannot be obtained. It is not economical. In addition, about the minimum of a compounding quantity, 5 weight% is preferable and the effect of more excellent stability, hair dyeing operability, dyeability, and fastness is acquired by mix | blending 5 weight% or more. The upper limit is preferably 20% by weight, and when it exceeds 20% by weight, the effects of stability, hair dyeing operability, dyeability and fastness are reduced.

  Examples of the higher alcohol include lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetostearyl alcohol, behenyl alcohol, isostearyl alcohol, oleyl alcohol, 2-hexyldecanol, and 2-octyldodecanol. Among these, lauryl alcohol, myristyl alcohol, cetyl alcohol, stearyl alcohol, cetostearyl alcohol, and behenyl alcohol, which are straight chain higher saturated alcohols, are particularly preferable from the viewpoint of stability.

  Examples of the hydrocarbon include paraffin, liquid paraffin, liquid isoparaffin, light liquid paraffin, light liquid isoparaffin, heavy liquid isoparaffin, petroleum jelly, squalane, ceresin, microcrystalline wax, ozokerite, and pristane.

Furthermore, when at least one nonionic surfactant selected from POE alkyl ethers and POE alkyl allyl ethers is added as the (e) group component, excellent effects in terms of dyeability and fastness can be obtained.

The nonionic surfactant include the following.

1. Polyoxyethylene (hereinafter abbreviated as POE ) alkyl ether 1. POE cetyl ether, POE stearyl ether, POE behenyl ether, POE oleyl ether, POE lauryl ether, etc. POE alkyl allyl ether POE nonyl phenyl ether, POE octyl phenyl ether, etc.

The blending amount is 0.01 to 40% by weight, and if it is less than 0.01% by weight, sufficient dyeability and fastness cannot be obtained. Not right. In addition, about the minimum of a compounding quantity, 0.1 weight% is preferable and the more outstanding dyeing | staining property and fastness are acquired by mix | blending 0.1 weight% or more. The upper limit is preferably 30% by weight, and when it exceeds 30% by weight, the increase in dyeability and fastness is reduced. In particular, the dyeability using non-ionic surfactant, a better effect in terms of fastness is obtained. Further, when the weight ratio of the (d) group component and the (e) group component is d: e = 1: 0.1 to 10, more excellent dyeability and fastness can be obtained.

  Other oxidation dye intermediates include paraphenylenediamines, paratoluylenediamines, aminophenols, aminonitrophenols, diphenylamines, diaminophenylamines, N-phenylphenylenediamines, diaminopyridines, and the like. Of these salts. The compounding quantity is about 0.01 to 10 weight% with respect to the total weight of a hair dye composition, for example. Moreover, pyrogallol, catechol, metaphenylenediamine, etc. can be mix | blended as a coupler. In addition, those listed in "Quasi-drug raw material standards" (issued in June 1991, Yakuji Nippo) can be used. Furthermore, humectants such as glycerin, propylene glycol and polyethylene glycol, stabilizers such as sulfites and ascorbic acid, thickeners such as carboxymethylcellulose and xanthan gum, alkali agents such as ammonia and alkanolamine, and fragrances as necessary. It can mix | blend suitably.

  On the other hand, it contains hydrogen peroxide, urea peroxide, etc. as oxidizing agents, and also requires stabilizers such as phenacetin and EDTA, surfactants, fats and oils, higher alcohols, acids, pH adjusters, fragrances, etc. It can mix | blend suitably according to it.

  When this hair dye is used, a hair dye composition is prepared by mixing the hair dye composition and the oxidizing agent immediately before the hair dyeing treatment and applied to the hair. Examples of the dosage form include liquids, creams, gels, pastes, and the like. Among these, creams are preferable in terms of dyeability and fastness because of good adhesion to hair during hair dyeing. Moreover, if it is a gradual dyeing | staining type, by repeating hair dyeing operation 2 to several times, a gray hair can be made gradually inconspicuous without being noticed by a person.
