Description

[Technical Field]

[0001] The present invention relates to hair dye or bleach products. [Background technology]

[0002] Conventionally, methods for dyeing or bleaching hair have been known that achieve their effects by using a mixture of multiple agents, such as hair dye compositions that consist of a first-agent composition containing an oxidative dye and an alkaline agent and a second-agent composition containing an oxidizing agent such as hydrogen peroxide, and bleach compositions that consist of a first-agent composition containing an alkaline agent such as aqueous ammonia and a second-agent composition containing an oxidizing agent.

[0003] Many commercially available hair dye or bleach products are intended for medium-length hair, and for people with long or thick hair, one set is simply not enough, leaving them dissatisfied with the dye or bleach effect. Therefore, some people try to buy multiple sets of the same product, but there is a time lag when mixing and preparing the hair dye or bleach composition multiple times and applying it to the hair, which can cause concerns that the dye or bleach effect may not be uniform.

[0004] It is said that the average hair weight for medium-length hair is about 100 to 120 g, and for long hair it is about 130 to 180 g. Commercially available hair dye or bleach products often contain a hair dye or bleach composition in an amount of about 120 g. If the required amount of hair dye or bleach composition per gram of hair is set at 1 g, satisfactory hair dye or bleaching effects will not be achieved for people with long or thick hair. Therefore, there is a demand for hair dye or bleach compositions with increased content.

[0005] For example, a method for treating hair has been studied in which a hair dye or bleach composition in the form of a milky or gel obtained by mixing a first agent composition and a second agent composition is applied to the hair, and the composition is lathered on the hair to dye or bleach the hair in the foamy state, and good results have been obtained in terms of mixability and dischargeability from the container (Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-184965 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-184968 Summary of the Invention [Problem to be solved by the invention]

[0007] However, increasing the amount of hair dye or bleach composition means increasing the amounts of the first-agent composition and the second-agent composition, which may prevent thorough mixing in a container for medium-length hair. Furthermore, even if the amount of hair dye or bleach composition is increased, it may not be easily dispensed from the container itself, and if a large amount remains, there is a concern that the actual amount used will remain the same as before. Many of the first-agent and second-agent compositions previously studied have been designed to improve mixability and usability when the total amount of the hair dye or bleach composition is around 120 g. Simply increasing the amounts of the first-agent and second-agent compositions previously studied may result in inferior mixability and usability compared to conventional compositions. Therefore, it is very difficult to increase the amount of hair dye or bleach composition while maintaining a satisfactory hair dye or bleaching effect, and there is still room for improvement. [Means for solving the problem]

[0008] As a result of extensive research into solving the above problems, the present inventors have found that it is possible to provide a hair dye or bleach product comprising a hair dye or bleach composition composed of a first-agent composition containing an alkaline agent and a second-agent composition containing an oxidizing agent, and a container capable of receiving the first-agent composition containing the alkaline agent and the second-agent composition containing the oxidizing agent so that they can be mixed at the time of use, the total amount of the hair dye or bleach composition being 150 to 210 g, the container comprising a container body and a cap, the container body being made of synthetic resin and having a circular or oval bottom, a bottom diameter of 54 to 62 mm, a height of 116 to 152 mm, a thickness of 0.2 to 2 mm, and a body opening diameter of 16 to 36 mm. [Effects of the Invention]

[0009] The present invention provides a hair dye or bleach product that has excellent mixability between the first and second agent compositions, allows the hair dye or bleach composition to be dispensed from the container body in the exact amount, leaves only a small amount of hair dye or bleach composition in the container body after use, and provides satisfactory hair dye or bleaching effects.

[0011] The present invention will be described in detail below. Note that the units indicating the contents are all % by mass unless otherwise specified.

[0012] The hair dye or bleach composition according to the present invention is composed of a first agent composition containing an oxidation dye and an alkaline agent and a second agent composition containing an oxidizing agent, or a first agent composition containing an alkaline agent and a second agent composition containing an oxidizing agent, and these are mixed together when used.

[0013] The hair dye or bleach composition according to the present invention preferably contains an ionic surfactant, more preferably a cationic surfactant and an anionic surfactant, from the viewpoints of mixability, ease of use upon application, spreadability, and compatibility with hair.

[0014] The first agent composition of the hair dye or bleach composition according to the present invention contains a cationic surfactant, which improves mixability, ease of use and spreadability during application, and compatibility with hair, allowing for even dyeing or bleaching of hair.

[0015] The cationic surfactant used in the present invention is not particularly limited, and examples thereof include behenyltrimethylammonium chloride, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, cetyltrimethylammonium bromide, stearyltrimethylammonium bromide, lanolin ethyl sulfate fatty acid aminopropylethyldimethylammonium, and stearic acid diethylaminoethylamide, and the like, and the present invention may contain one or more selected from these. Among these, behenyltrimethylammonium chloride is preferred from the viewpoints of mixability, ease of use during application, spreadability, and compatibility with hair.

[0016] The content of the cationic surfactant in the hair dye or bleach 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 is less than 0.3% or more than 1.6%, the composition may have poor mixability, ease of application, spreadability, and compatibility with hair, resulting in uneven dyeing or bleaching of hair.

[0017] The first agent composition of the hair dye or bleach composition according to the present invention may contain an oxidation dye, which can be used to dye hair.

[0018] The oxidation dye used in the present invention means a dye used in an oxidation hair dye such as a dye intermediate or a coupler.

[0019] The oxidation dye used in the present invention is not particularly limited, but examples thereof include paraphenylenediamine, toluene-2,5-diamine, orthoaminophenol, paraaminophenol, metaaminophenol, 5-aminoorthocresol, resorcinol, 2,6-diaminopyridine, 2,4-diaminophenoxyethanol, 1-naphthol, and salts thereof. Other dyes listed in the "Standards for Quasi-drug Raw Materials 2006 Integrated Edition" (published November 2013, Yakuji Nipposha) can also be used as appropriate. These dyes may be contained alone or in combination.

[0020] The first agent composition of the hair dye or bleach composition according to the present invention contains an alkaline agent, which can enhance the hair dyeing or bleaching effect.

[0021] The alkaline agent used in the present invention is not particularly limited, but examples thereof include monoethanolamine, diethanolamine, triethanolamine, ammonia, ammonium carbonate, potassium carbonate, sodium carbonate, ammonium bicarbonate, sodium bicarbonate, ammonium sulfate, arginine, etc. One or more selected from these may be contained. Among these, monoethanolamine or ammonia is preferred from the viewpoint of hair dyeing or bleaching effects.

[0022] The content of the alkaline agent in the hair dye or bleach composition of the present invention is preferably 0.06 to 4.5%. If the content of the alkaline agent is less than 0.06%, sufficient hair dyeing or bleaching effect may not be obtained. On the other hand, if the content of the alkaline agent is more than 4.5%, significant damage to hair may occur.

[0023] The second agent composition of the hair dye or bleach composition according to the present invention contains an anionic surfactant, which improves mixability, ease of use and spreadability during application, and compatibility with hair, allowing for even dyeing or bleaching of hair.

[0024] The anionic surfactant used in the present invention is not particularly limited, and examples thereof 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 the present invention may contain one or more selected from these. Among these, sodium cetyl sulfate is preferred from the viewpoints of mixability, ease of use during application, spreadability, and compatibility with hair.

[0025] The content of the anionic surfactant in the hair dye or bleach composition of the present invention is preferably 0.2 to 0.6%, more preferably 0.24 to 0.56%. If the content of the anionic surfactant is less than 0.2% or more than 0.6%, the composition may become less compatible, less usable when applied, less spreadable, and less compatible with hair, resulting in uneven dyeing or bleaching of hair.

[0026] The second agent composition of the hair dye or bleach composition according to the present invention contains an oxidizing agent, which decomposes the melanin pigment contained in the hair and bleaches the hair.

[0027] The oxidizing agent used in the present invention is not particularly limited, and examples thereof 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 the composition may contain one or more selected from these. Among these, hydrogen peroxide is preferred from the viewpoint of bleaching power.

[0028] The content of the oxidizing agent in the hair dye or bleach composition of the present invention is preferably 1.8 to 4.8%. If the content of the oxidizing agent is less than 1.8%, sufficient bleaching power may not be obtained. On the other hand, if the content of the oxidizing agent is more than 4.8%, significant damage to hair may occur.

[0029] If the cationic surfactant and the anionic surfactant used in the present invention are contained in the same agent, they may aggregate and become unstable over time. Therefore, it is preferable to contain them in separate compositions.

[0030] By containing the cationic surfactant and the anionic surfactant used in the present invention in separate compositions, the viscosity can be easily increased when they are mixed, and the ease of application, spreadability, and compatibility with hair can be improved.

[0031] In addition to the above-mentioned components, the hair dye or bleach composition according to the present invention can contain various components typically used in cosmetics, quasi-drugs, pharmaceuticals, etc., within the range that does not impair the effects of the present invention. For example, direct dyes, acid dyes, basic dyes, HC dyes, higher alcohols, higher fatty acids, hydrocarbon oils, silicone oils, nonionic surfactants, lower alcohols, humectants, solvents such as polyhydric alcohols, water-soluble polymers, thickeners, antioxidants, UV absorbers, pH adjusters, chelating agents, preservatives, antibacterial agents, medicinal ingredients, protein derivatives, hydrolyzed proteins, amino acids, stabilizers, fragrances, animal and vegetable oils, vitamins, plant extracts, inorganic salts, etc., and these can be contained alone or in combination depending on the purpose.

[0032] The total amount of the hair dye or bleach composition according to the present invention is preferably 150 to 210 g, more preferably 165 to 195 g. If the total amount of the hair dye or bleach composition is less than 150 g, the hair dyeing or bleaching effect may not be fully achieved for those with a larger amount of hair. Furthermore, if the total amount of the hair dye or bleach composition exceeds 210 g, the mixing of the first and second agent compositions may be impaired.

[0033] The container for use in the hair dye or bleach product according to the present invention comprises a container body and a cap.

Among these, low-density polyethylene or high-density polyethylene is preferred from the viewpoints of ease of removal from the container body and residual properties.

[0036] The shape of the bottom of the container body of the hair dye or bleach product according to the present invention is not particularly limited, but from the viewpoint of mixing efficiency and ease of dispensing from the container body, a circular or oval shape is preferred.

[0037] The body of the container body of the hair dye or bleach product according to the present invention is preferably a cylindrical container having the same shape as the bottom. Of these, a circular or oval cylindrical container is preferred, as this is easy to hold and facilitates mixing, and a container body without corners makes it less likely that the hair dye or bleach composition will remain in the container body.

[0038] When the shape of the bottom is circular, the diameter of the bottom of the container body of the hair dye or bleach product according to the present invention is preferably 54 to 62 mm, more preferably 56 to 60 mm, from the viewpoints of ease of dispensing from the container body and retention.

[0039] When the shape of the bottom of the container body of the hair dye or bleach product according to the present invention is oval, the diameter of the long side is preferably 82 to 90 mm and the short side is preferably 38 to 46 mm, from the viewpoint of ease of dispensing from the container body and retention.

[0040] The height of the container body of the hair dye or bleach product according to the present invention is preferably 116 to 152 mm, more preferably 123 to 142 mm, from the viewpoints of ease of dispensing from the container body and residual properties.

[0041] The thickness of the container body of the hair dye or bleach product according to the present invention is preferably 0.2 to 2 mm, more preferably 0.5 to 1.5 mm, from the viewpoint of mixing efficiency and ease of dispensing from the container body.

[0043] The void ratio of the container when the hair dye or bleach composition of the present invention is fully contained is preferably 17 to 41%, more preferably 23 to 35%. If the void ratio of the container when the hair dye or bleach composition is fully contained is less than 17%, the first and second agent compositions may not mix well. If the void ratio of the container when the hair dye or bleach composition is fully contained is more than 41%, the hair dye or bleach composition may be difficult to dispense from the container body.

[0044] The material of the cap used in the hair dye or bleach product according to the present invention is not particularly limited, but polypropylene (PP) can be used.

[0045] The shape of the cap used in the hair dye or bleach product according to the present invention is not particularly limited, but a circular shape is preferred from the viewpoint of ease of fastening to the container body.

[0046] The cap used in the hair dyeing or bleaching product according to the present invention is not particularly limited, but a separate type or hinged type cap can be used.

[0047] The first agent composition according to the present invention is preferably filled into various containers such as plastic containers, tube containers, aerosol containers, and pouch containers, and stored until use.

[0048] The second agent composition according to the present invention is preferably filled into a container for mixing and stored until use.

[0049] The hair dye or bleach composition according to the present invention is preferably used by transferring the entire amount of the first agent composition into a container filled with the second agent composition and mixing them at the time of use.

[0050] The viscosity of the hair dye or bleach composition according to the present invention is preferably 5,600 to 20,000 mPa·s, more preferably 6,300 to 16,000 mPa·s. If the viscosity of the hair dye or bleach composition is less than 5,600 mPa·s, it may spill when dispensed from the container, reducing the amount applied to the hair and potentially resulting in an insufficient hair dyeing or bleaching effect. Furthermore, if the viscosity of the hair dye or bleach composition exceeds 20,000 mPa·s, the first and second part compositions may not mix well, making it difficult to dispense from the container, and increasing the amount of residue remaining in the container, potentially resulting in an insufficient hair dyeing or bleaching effect.

[0051] In the present invention, the viscosity is measured by preparing a hair dye or bleach composition by a conventional method, filling 120 g of the obtained hair dye or bleach composition into a sample bottle (Food 140: manufactured by Daiichi Glass Co., Ltd.), and measuring the viscosity 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 at 25°C.

[0052] The hair dye or bleach composition according to the present invention preferably has a pH of 6 to 11 from the viewpoint of hair dyeing or bleaching effect.

[0053] In the present invention, the pH is adjusted by a conventional method, and 120 g of the obtained hair dye or bleach composition is filled into a sample bottle (Food 140: manufactured by Daiichi Glass Co., Ltd.), and the pH is measured at 20°C using a glass electrode type hydrogen ion concentration indicator (F-71: manufactured by Horiba, Ltd.).

[0054] The mixing ratio of the first and second agent compositions of the hair dye or bleach composition according to the present invention is not particularly limited, but the first and second agent compositions are preferably mixed at a ratio of 2:1 to 1:4, more preferably 1:1 to 1:3, just before use.

[0055] The hair dye or bleach composition according to the present invention is preferably in the form of a milky lotion from the viewpoints of ease of application to hair, ease of running fingers through hair when rinsing, and the condition of hair after finishing.

[0056] From the viewpoint of spreading and compatibility with hair during application, the hair dye or bleach composition of the present invention is preferably applied by hand, rather than using a brush, comb, brush-type nozzle, or the like.

[0057] The hair dye or bleach composition according to the present invention preferably does not foam even when massaged into the hair with the hands. [Example]
