DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] The present invention will be described below based on an embodiment of the present invention (hereinafter, referred to as "the present embodiment"). The first agent for oxidative hair dyeing in this embodiment (hereinafter sometimes referred to as "first agent") is used in mixture with the second agent for oxidative hair dyeing (hereinafter sometimes referred to as "second agent"), and the oxidative hair dye obtained by this mixture is used in the hair dyeing treatment method.
[0010] (First Agent) The first agent of the present embodiment is a blend of an oxidative dye, a surfactant, and water (the blended amount of water is, for example, 70 mass % or more). In addition, known raw materials for the first agent may be blended as optional raw materials in the first agent of the present embodiment.
[0011] The combination and amount of the oxidative dyes blended in the first agent of this embodiment are appropriately set in order to optimize the dyeing properties on hair, such as color tone, saturation, brightness, and deep dyeing ability.
[0012] As the oxidation dye to be blended in the first agent, one or more selected from known dye intermediates that develop color by themselves through oxidation reaction are used, with or without combination with a coupler described below. Examples of the dye intermediate include phenylenediamine derivatives such as toluene-2,5-diamine hydrochloride, toluene-2,5-diamine sulfate, toluene-2,5-diamine, nitroparaphenylenediamine hydrochloride, nitroparaphenylenediamine, and paraphenylenediamine; phenol derivatives such as 2,4-diaminophenol hydrochloride, orthoaminophenol sulfate, orthoaminophenol, paraaminophenol sulfate, and paraaminophenol; pyrazole derivatives such as 1-hydroxyethyl-4,5-aminopyrazole sulfate; and 2,2'-[(4-aminophenyl)imino]bisethanol sulfate.

Examples of couplers include phenylenediamine derivatives such as 2,4-diaminophenoxyethanol hydrochloride, metaphenylenediamine hydrochloride, and metaphenylenediamine; aminophenol derivatives such as 5-aminoorthocresol sulfate, 5-aminoorthocresol, 5-(2-hydroxyethylamino)-2-methylphenol, and metaaminophenol; resorcin; and α-naphthol.
[0014] The blending amount of the oxidative dye in the first agent of this embodiment should be set appropriately, and is, for example, from 0.01% by mass to 10% by mass.
[0015] As the surfactant to be blended in the first agent, one or more surfactants selected from known nonionic surfactants, cationic surfactants, anionic surfactants and amphoteric surfactants are used.
[0016] When a nonionic surfactant is blended in the first agent of this embodiment, examples of the nonionic surfactant include polyoxyethylene alkyl ether, polyoxyethylene polyoxypropylene alkyl ether, polyoxyethylene fatty acid ester, polyoxyethylene sorbitan fatty acid ester, polyoxyethylene sorbitol tetra fatty acid ester, glycerin fatty acid ester, sorbitan fatty acid ester, polyglycerin fatty acid ester, and sucrose fatty acid ester. It is preferable to blend one or more types of nonionic surfactant in the first agent, and the blending amount of the nonionic surfactant should be appropriately set, for example, 0.1% by mass or more and 10% by mass or less.
[0017] When a cationic surfactant is blended in the first agent of this embodiment, examples of the cationic surfactant include quaternary ammonium salts such as long-chain alkyl trimethyl ammonium salts, di-long-chain alkyl dimethyl ammonium salts, and monoalkyl ether-type quaternary ammonium salts. One or more types of cationic surfactants may be blended in the first agent, and the blending amount of the cationic surfactant should be appropriately set, but is, for example, 0.5% by mass or more and 8% by mass or less.

[0022] The amount of the alkaline agent to be mixed in the first agent of this embodiment should be appropriately set, but is, for example, an amount that results in a free alkali amount of 5 ml to 20 ml. Here, the "free alkali amount" is the amount of 0.1 N hydrochloric acid solution added when 100 ml of water, 1.0 g of the first agent, and 10 ml of ethanol are mixed and titrated with 0.1 N hydrochloric acid solution, resulting in a pH of 4.8.
[0023] The pH of the first agent of this embodiment at 25° C. should be appropriately set, for example, from 5 to 13. To improve the permeability and dyeability of the oxidative dye into the hair, the pH should be 7 or higher, and preferably 8 or higher. The pH can be adjusted by adding an alkaline agent.
[0024] The form of the first agent according to the present embodiment is not particularly limited, and may be, for example, an oil-in-water emulsion such as a liquid, cream, wax, gel, etc. The viscosity of the first agent is, for example, 10,000 mPa s or more and 60,000 mPa s or less as measured 60 seconds later at 25° C. and 12 rpm using a Brookfield viscometer.
[0025] (Second agent) The second agent of the present embodiment is a mixture of an oxidizing agent and water (the amount of water is, for example, 70 mass % or more). In addition, known raw materials for the second agent may be mixed as optional raw materials into the second agent according to the present embodiment.
[0026] The oxidizing agent blended in the second agent promotes the oxidative polymerization of the oxidation dye and improves the dyeability. The oxidizing agent may be selected from one or more known oxidizing agents, such as hydrogen peroxide, bromates, percarbonates, and perborates. The blending amount of the oxidizing agent in the second agent of the present embodiment should be appropriately set, and is, for example, 1% by mass or more and 7% by mass or less.
[0027] Examples of known second agent raw materials that may be optionally blended into the second agent of this embodiment include nonionic surfactants, cationic surfactants, anionic surfactants, amphoteric surfactants, higher alcohols, polyhydric alcohols, sugars, ester oils, fats and oils, fatty acids, hydrocarbons, waxes, silicones, polymeric compounds, amino acids, animal and plant extracts, substances derived from microorganisms, inorganic compounds, fragrances, preservatives, sequestering agents, and ultraviolet absorbers.
[0028] When hydrogen peroxide is blended as an oxidizing agent, the pH of the second agent according to this embodiment at 25° C. is, for example, from 1 to 4. The pH can be adjusted by blending a pH adjuster such as an organic acid, an organic acid salt, an inorganic acid, or an inorganic acid salt.
[0029] The dosage form of the second agent according to this embodiment is not particularly limited, and examples thereof include oil-in-water emulsions such as liquids, creams, gels, etc. The viscosity of the second agent is, for example, 2000 mPa s or more and 15000 mPa s or less after 60 seconds measured at 25° C. and 12 rpm using a Brookfield viscometer.
[0030] (Oxidation hair dye) The oxidation hair dye of the present embodiment is obtained by mixing the first and second agents of the present embodiment described above. The mass ratio in this mixture is, for example, first agent:second agent=1:0.5 or more and 3 or less.
[0031] The lower limit of the pH of the oxidative hair dye according to this embodiment at 25° C. should be set appropriately, but for example, the pH is 5 or more, and in order to promote the penetration of the oxidative dye into the inside of the hair, a pH of 8 or more is preferable. On the other hand, the upper limit of the pH should also be set appropriately, but a pH of 12 or less is preferable for suppressing irritation to the skin.
[0032] The form of the oxidative hair dye according to the present embodiment when used is not particularly limited, and examples thereof include liquid, cream, wax, gel, and foam (foam). In consideration of handling such as application to hair and dripping during use, the oxidative hair dye according to the present embodiment is preferably in cream form.
[0033] (Hair dyeing method) The hair dyeing method of the present embodiment is carried out in the same manner as known hair dyeing methods, by applying the oxidative hair dye of the present embodiment to hair, followed by washing and removing the oxidative hair dye. The hair to be dyed includes various types of hair, such as chemically damaged hair (hair that has been dyed with an oxidative hair dye, hair that has been permed by straightening or shaping, etc.), physically damaged hair by brushing, healthy hair, hard hair, and soft hair.
