A double-aerosol device including: inner containers that separately store a plurality of types of hair treatment compositions used by mixing as hair dye, a decoloring agent, or dye remover; and an outer container in which a plurality of inner containers are stored; in which the hair treatment compositions are discharged to the outside by contracting the inner containers by a pressure of propellant, the outer container is configured such that at least a part of the inside of the outer container is visible so as to confirm remaining amounts of the hair treatment compositions, and the inner containers store the hair treatment compositions in pouches.


To provide a hair dye composition in a constitution containing a carbonate in the hair dye composition, which is capable of improving stability of the dye, and a method for stabilizing a color tone of a hair dyed by the hair dye composition. The present invention is concerned with a hair dye composition containing a carbonate, which includes (A) at least one selected from resorcin and its derivatives, and salts thereof, an upper limit of a compounding amount of the component (A) being 0.2% by mass or less, and (B) at least one dye selected from 5-(2-hydroxyethylamino)-2-methylphenol, 1,5-dihydroxynaphthalene, and a nitro dye.


A hair cosmetic material includes a first agent containing an alkali agent and a second agent containing an oxidizing agent. These first agent and second agent are used in a double structure container provided with a mechanism of separating the first agent and the second agent from each other and simultaneously discharging the both agents by a propellant. In the double structure container, a space for filling the first agent and a space for filing the second agent are each independently provided in the inside of a compressed gas filling space having a propellant for pressurization filled therein. Each of the first agent and the second agent is discharged in a liquid state, and each of the first agent and the second agent has a viscosity falling within the range of from 7,000 to 30,000 mPas at 25C.


To provide a stability improver of an aromatic compound, which is capable of improving stability of the aromatic compound, and a method for improving stability of an aromatic compound. The stability improver of an aromatic compound of the present invention includes (A) at least one selected from resorcin and its derivatives, and salts thereof. The aromatic compound may be at least one selected from an aromatic amine, an aromatic nitro compound, a phenol compound, an aromatic azo compound, and a fused ring compound.


To provide a first agent for oxidation hair dye in a constitution containing a carbonate in the first agent for oxidation hair dye, the first agent for oxidation hair dye being capable of improving stability of the dye, and a method for stabilizing a color tone of hair dyed by an oxidation hair dye composition. The present invention is concerned with a first agent for oxidation hair dye containing a carbonate, the first agent including (A) at least one selected from resorcin and its derivatives, and salts thereof, an upper limit of a compounding amount of the component (A) being 0.2% by mass or less, (B) at least one coupler selected from m-aminophenol, 5-amino-o-cresol, and -naphthol, and (C) 0.01 to 0.45% by mass of at least one dye intermediate selected from p-phenylenediamine, toluene-2,5-diamine, p-aminophenol, N,N-bis(2-hydroxyethyl)-p-phenylenediamine, and derivatives thereof, and salts thereof, a mass ratio of a content of the component (B) to a content of the component (A) being 0.5 to 10.
