[0001] The present invention relates to a hair dye composition.

Background Art

[0002] Conventionally, as a hair dye composition, there is known one that exhibits an effect by mixing and using a plurality of agents. For example, a hair dye composition composed of a first agent composition containing an oxidation dye and an alkali agent and a second agent composition containing an oxidizing agent is known. The alkali agent activates the action of the oxidizing agent to promote the decomposition of melanin pigments in the hair, and swells the hair to improve the permeability of the dye into the hair. The oxidizing agent is involved not only in the decomposition of melanin pigments but also in the coloring of oxidation dyes.

[0003] Generally well-known types of hair dye compositions include a cream-type one in which the same amount of each of the cream-like first agent composition and the second agent composition is discharged into a tray-shaped container and mixed for use, an emulsion-type one in which the full amount of the cream-like first agent composition is added to a bottle filled with an emulsion-like or liquid second agent composition and shaken, and then the hair is dyed using a brush-type nozzle, an aerosol-type foam-type one in which the first agent composition and the second agent composition discharged in a foamy state by forming bubbles using an aerosol with an ejectant such as liquefied gas are mixed for use, and a non-aerosol-type foam-type one in which the full amount of the liquid first agent composition is added to a non-aerosol foam container such as a pump foamer or a squeeze foamer filled with a liquid second agent composition to form bubbles incorporating air and used, etc.

[0004] Cream-type hair dyes can be stored and used to dye only the roots each time, but because many are applied with a brush, it can be difficult to apply evenly to the inside of the hair, resulting in uneven coloring. Lotion-type dyes are often applied with a brush-type nozzle, so the dye composition needs to be somewhat soft, and although they blend well with the hair, care must be taken to prevent dripping and splashing. Foam-type dyes are easy for beginners to use because they are applied by massaging them in with the hands like shampooing, but the dye composition is bulky, so the amount that can be taken in at one time is actually small, which can easily lead to uneven coloring and dissatisfaction.

[0005] In all types, many products are specialized for ease of use during hair dyeing, but concerns remain regarding how easily the hair can be combed after rinsing and the condition of the hair after dyeing. Therefore, in recent years, there has been a demand for hair dye compositions that are easy to apply, spread well and blend into the hair, are easy to comb after rinsing and the hair is in good condition after dyeing, and provide satisfactory hair coloring.

[0006] For example, as a hair dye composition applied by hand, studies have been conducted on compositions that combine specific nonionic surfactants to provide viscosity that prevents dripping when applied to the hair (Patent Documents 1 and 2), and compositions that form good quality foam (Patent Document 3). [Prior art documents] [Patent Documents]

[0007] [Patent Document 1] Japanese Patent Publication No. 2013-181032 [Patent Document 2] Japanese Patent Publication No. 2013-93855 [Patent Document 3] Japanese Patent Publication No. 2012-31072 [Overview of the Initiative] [Problems that the invention aims to solve]

[0008] However, in order to give the hair dye composition a viscosity that prevents dripping when applied by hand and to form a good foam, it was necessary to incorporate a large amount of surfactant into the hair dye composition. However, incorporating a large amount of surfactant resulted in excessive degreasing of the hair, making it difficult to comb through the hair when rinsing the dye composition, and leaving the hair feeling dry and unsatisfactory after the dyeing process. Therefore, it was extremely difficult to maintain satisfactory usability and high dyeing power while keeping the hair smooth when rinsing and the condition of the hair after the dyeing process was good, and there was still room for improvement. [Means for solving the problem]

[0009] As a result of diligent research to solve the above problems, the present inventors have found that they can provide a hair dye composition comprising at least a first composition containing an alkaline agent and a second composition containing an oxidizing agent, which are mixed and used at the time of use, wherein the first composition contains (A) a cationic surfactant, (B) a silicone oil, and (C) a hydrocarbon oil, and the second composition contains (D) an anionic surfactant. [Effects of the Invention]

[0010] The present invention provides a hair dye composition that offers good usability during application, excellent spreadability and compatibility with hair during application, good manageability during rinsing, good hair condition after finishing, and satisfactory hair coloring. [Modes for carrying out the invention]

[0011] The present invention will be described in detail below. Unless otherwise specified, all units indicating content are in mass percent.

[0012] The first component of the hair dye composition according to the present invention contains (A) a cationic surfactant. This improves the ease of application, spreadability, and compatibility with the hair, allowing for even dyeing of the hair.

[0013] The cationic surfactant (A) used in the present invention is not particularly limited, but for example, Examples include behenyltrimethylammonium chloride, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, cetyltrimethylammonium bromide, stearyltrimethylammonium bromide, lanolin fatty acid aminopropylethyldimethylammonium ethyl sulfate, and diethylaminoethylamide stearate. One or more of these can be selected and included. Among these, behenyltrimethylammonium chloride is preferred from the viewpoint of ease of application, spreadability, and compatibility with hair.

[0014] The content of the cationic surfactant (A) used in the hair dye composition of the present invention is preferably 0.3 to 1.6%, more preferably 0.4 to 1.2%. If the content of the cationic surfactant (A) is less than 0.3% or more than 1.6%, the usability, spreadability, and compatibility with hair during application may be poor, and there is a risk of uneven hair dyeing.

[0015] The first component of the hair dye composition according to the present invention contains (B) silicone oil.

[0016] The (B) silicone oil used in the present invention is not particularly limited, but examples include methylpolysiloxane, highly polymerized methylpolysiloxane, decamethylcyclopentasiloxane, methylphenylpolysiloxane, methylcyclopolysiloxane, amino-modified silicone, polyether-modified silicone, etc., and one or more selected from these may be included. Among these, methylpolysiloxane is preferred from the viewpoint of how easily the hair can be combed when rinsing after dyeing and the condition of the hair after finishing.

[0017] The first component of the hair dye composition according to the present invention contains (C) hydrocarbon oil.

[0018] The (C) hydrocarbon oil used in the present invention is not particularly limited. For example, liquid paraffin, liquid isoparaffin, light isoparaffin, light liquid isoparaffin, heavy liquid isoparaffin, squalane, α-olefin oligomer, etc. may be mentioned, and one or more selected from these can be contained. Among them, liquid paraffin is preferable from the viewpoints of smooth finger combing during rinsing after hair dyeing and the state of the hair after finishing.

[0019] By using the (B) silicone oil and the (C) hydrocarbon oil used in the present invention in combination, it is possible to obtain an extremely good state of the hair during rinsing after hair dyeing and the state of the hair after finishing, which cannot be achieved by conventional general techniques.

[0020] The total amount of the (B) silicone oil and the (C) hydrocarbon oil in the hair dye composition used in the present invention is preferably 0.33 to 3%, more preferably 0.73 to 2.33%. When the total amount of the (B) silicone oil and the (C) hydrocarbon oil is less than 0.33% or exceeds 3%, the finger combing during rinsing after hair dyeing deteriorates, and there is a risk of feeling limpness or stickiness in the hair after finishing.

[0021] The mass ratio (C) / (B) of the contents of the (B) silicone oil and the (C) hydrocarbon oil used in the present invention is not particularly limited, but from the viewpoints of smooth finger combing during rinsing after hair dyeing and the state of the hair after finishing, it is preferably in the range of 0.7 to 2, more preferably 1.2 to 1.8. When the mass ratio (C) / (B) of the contents of the (B) silicone oil and the (C) hydrocarbon oil is less than 0.7 or exceeds 2, the finger combing during rinsing after hair dyeing deteriorates, and there is a risk of feeling limpness or stickiness in the hair after finishing.

[0022] The first agent composition of the hair dye composition according to the present invention contains an oxidation dye. Thereby, the hair can be dyed.

[0023] The oxidation dye used in the present invention means a dye used in oxidation hair dyes such as dye intermediates and couplers.

[0024] The oxidation dye used in the present invention is not particularly limited. For example, paraphenylenediamine, toluene-2,5-diamine, ortho-aminophenol, para-aminophenol, meta-aminophenol, 5-amino-o-cresol, resorcinol, 2,6-diaminopyridine, 2,4-diaminophenoxyethanol, 1-naphthol and their salts can be mentioned. In addition, those listed in "Pharmaceutical Excipients Raw Material Standards 2006 Integrated Edition" (published by Yakujihosha in November 2013) can also be appropriately used. These dyes can contain one kind or two or more kinds.

[0025] The first agent composition of the hair dye composition according to the present invention contains an alkali agent. Thereby, the hair bleaching and hair dyeing effects can be enhanced.

[0026] The alkali agent used in the present invention is not particularly limited. For example, monoethanolamine, diethanolamine, triethanolamine, aqueous ammonia, ammonium carbonate, potassium carbonate, sodium carbonate, ammonium bicarbonate, sodium bicarbonate, ammonium sulfate, arginine, etc. can be mentioned. One kind or two or more kinds selected from these can be contained. Among them, from the viewpoint of the bleaching and hair dyeing effects, monoethanolamine and aqueous ammonia are preferable.

[0027] The content of the alkali agent in the hair dye composition used in the present invention is preferably 0.1 to 3.33%. When the content of the alkali agent is less than 0.1%, there is a risk that sufficient bleaching and hair dyeing effects cannot be obtained. Also, when it exceeds​​​​​​​The anionic surfactant (D) used in the present invention is not particularly limited, but for example, Examples include sodium cetyl sulfate, sodium lauryl sulfate, potassium lauryl sulfate, ammonium lauryl sulfate, triethanolamine lauryl sulfate, sodium polyoxyethylene lauryl ether sulfate, triethanolamine polyoxyethylene lauryl ether sulfate, ammonium polyoxyethylene lauryl ether sulfate, polyoxyethylene lauryl ether phosphate, triethanolamine dodecylbenzenesulfonate, sodium tetradecenesulfonate, sodium N-lauroylmethyl-β-alanine, sodium N-acyl-L-glutamate, etc., and one or more of these can be selected and included. Among these, sodium cetyl sulfate is preferred from the viewpoint of ease of application, spreadability, and good compatibility with hair.

[0030] The content of the anionic surfactant (D) used in the hair dye composition is preferably 0.2 to 0.6%, more preferably 0.24 to 0.56%. If the content of the anionic surfactant (D) is less than 0.2% or more than 0.6%, the usability, spreadability, and compatibility with hair during application may be poor, and there is a risk of uneven hair dyeing.

[0031] The second component of the hair dye composition according to the present invention contains an oxidizing agent. This allows the melanin pigment contained in the hair to be broken down and the hair to be decolorized.

[0032] The oxidizing agent used in the present invention is not particularly limited, but examples include hydrogen peroxide, urea peroxide, melamine peroxide, sodium percarbonate, potassium percarbonate, sodium perborate, potassium perborate, ammonium persulfate, sodium peroxide, potassium peroxide, magnesium peroxide, barium peroxide, calcium peroxide, strontium peroxide, sodium bromate, etc., and one or more selected from these may be included. Among these, hydrogen peroxide is preferred from the viewpoint of decolorizing power.

[0033] The content of the oxidizing agent used in the present invention in the hair dye composition is preferably 2 to 4%. If the content of the oxidizing agent is less than 2%, sufficient bleaching power may not be obtained. If it exceeds 4%, there is a risk of significant damage to the hair.

[0034] The cationic surfactant (A) and the anionic surfactant (D) used in the present invention may become unstable over time if they are combined in the same agent, potentially leading to aggregation. Therefore, it is preferable to combine them in separate compositions and mix them at the time of use to increase viscosity.

[0035] The hair dye composition according to the present invention may contain various ingredients commonly used in cosmetics, quasi-drugs, pharmaceuticals, etc., in addition to the above-mentioned ingredients, as long as they do not impair the effects of the present invention. For example, direct dyes, acid dyes, basic dyes, HC dyes, oils such as higher alcohols and higher fatty acids, nonionic surfactants, lower alcohols, humectants, solvents such as polyhydric alcohols, water-soluble polymers, thickeners, antioxidants, UV absorbers, pH adjusters, chelating agents, preservatives, antibacterial agents, pharmacoactive ingredients, protein derivatives, hydrolyzed proteins, amino acids, stabilizers, fragrances, animal and vegetable oils, vitamins, plant extracts, inorganic salts, etc., and one or more of these may be included depending on the purpose.

[0036] The first and second component compositions according to the present invention are filled into various containers such as poly containers, tube containers, aerosol containers, and pouch containers, and stored until use.

[0037] The hair dye composition according to the present invention is preferably used by mixing the first component composition and the second component composition at the time of use in a ratio of 1:1 to 1:3, more preferably 1:2, from the viewpoint of hair bleaching and hair dyeing effects.

[0038] From the viewpoint of usability during application, the hair dye composition according to the present invention preferably has a viscosity of 5,000 to 30,000 mPa·s under conditions of 25°C.

[0039] In this invention, viscosity is measured by a conventional method, filling a sample bottle (Food 140: manufactured by Daiichi Glass Co., Ltd.) with 120 g of the obtained hair dye composition, and measuring it using a B-type viscometer with a helical stand (model: digital viscometer TVB-10M, manufactured by Toki Sangyo Co., Ltd.) with an M4 rotor for 1 minute at a rotation speed of 12 rpm and 25°C.

[0040] The hair dye composition according to the present invention preferably has a pH of 9 to 11 under conditions of 20°C, from the viewpoint of bleaching and hair dyeing effects.

[0041] In this invention, pH is prepared by a conventional method, and 120 g of the obtained hair dye composition is filled into a sample bottle (Food 140: manufactured by Daiichi Glass Co., Ltd.) and measured under conditions of 20°C using a glass electrode type hydrogen ion concentration indicator (F-71: manufactured by Horiba, Ltd.).

[0042] The hair dye composition according to the present invention is preferably applied by hand, without using a brush, comb, brush-type nozzle, etc., from the viewpoint of ease of application and compatibility with the hair.

[0043] The dosage form of the hair dye composition according to the present invention is preferably a cream or an emulsion.
