Description

[Technical Field]

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

[0002] Conventionally, hair dye compositions that exhibit their effects by using a mixture of multiple agents have been known. For example, a hair dye composition composed of a first agent composition containing an oxidation dye and an alkaline agent and a second agent composition containing an oxidizing agent is known. The alkaline agent activates the oxidizing agent to promote the decomposition of melanin pigment in the hair and swells the hair, improving the penetration of the dye into the hair. The oxidizing agent is involved not only in the decomposition of melanin pigment but also in the color development of the oxidation dye.

[0003] Commonly known types of hair dye compositions include cream types that can be stored, in which equal amounts of a cream-like first-agent composition and a cream-like second-agent composition are dispensed into a tray-like container and mixed for use; emulsion types that involve adding the entire amount of a cream-like first-agent composition to a bottle filled with an emulsion-like or liquid second-agent composition, shaking to mix, and then using a brush-type nozzle to dye the hair; aerosol foam types that involve mixing the first-agent composition and the second-agent composition, which are dispensed in foam form using a propellant such as liquefied gas to form bubbles using an aerosol; and non-aerosol foam types that involve adding the entire amount of a liquid first-agent composition to a non-aerosol foamer container such as a pump foamer or squeeze foamer filled with a liquid second-agent composition, and forming bubbles that incorporate air.

[0004] Cream-type hair dye compositions can be stored and used to dye only the roots, but many of them require the use of a brush, which can prevent the composition from being applied properly to the inside of the hair, resulting in unevenness. Emulsion-type compositions are often applied using a brush-type nozzle, which requires the composition to be softened to a certain extent. Although they blend well with the hair, care must be taken to prevent dripping and splashing. Foam-type compositions can be easily applied by rubbing them in with the hands, similar to shampooing, making them easy for even beginners to dye their hair. However, because the hair dye composition is bulky and the amount that can be applied at one time is substantially small, the resulting color can be uneven and unsatisfactory.

[0005] In either case, many of them are specialized in usability during hair dyeing, and some of them have concerns about the smoothness of the hair when rinsing after dyeing and the condition of the hair after finishing. Therefore, in recent years, there has been a demand for hair dye compositions that are easy to use during application, spread well on the hair and blend well into the hair when applied, have good smoothness of the hair when rinsing and good condition of the hair after finishing, and also provide satisfactory hair dyeing.

[0006] For example, hair dye compositions that are applied by hand have been studied that combine specific nonionic surfactants to give them viscosity that prevents them from dripping when applied to hair (Patent Documents 1 and 2), and that form good quality foam (Patent Document 3). [Prior art documents] [Patent documents]

[0007] [Patent Document 1] Japanese Patent Application Laid-Open No. 2013-181032 [Patent Document 2] Japanese Patent Application Laid-Open No. 2013-93855 [Patent Document 3] Japanese Patent Application Laid-Open No. 2012-31072 Summary of the Invention [Problem to be solved by the invention]

[0008] However, in order to impart a viscosity that prevents dripping when applied by hand and to form a good foam, it has been necessary to incorporate a large amount of surfactant into the hair dye composition. The incorporation of a large amount of surfactant results in an excessively strong degreasing power for the hair, which makes the hair dye composition difficult to run fingers through when rinsed off, leaving dissatisfied hair such as dryness after finishing. Therefore, it is extremely difficult to maintain satisfactory usability and high hair dyeing power while maintaining good runnability during rinsing and good hair condition after finishing, and there is still room for improvement. [Means for solving the problem]

[0009] 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 composition comprising at least a first-component composition containing an alkaline agent and a second-component composition containing an oxidizing agent, which are mixed together at the time of use, wherein the first-component composition contains (A) a cationic surfactant, (B) a silicone oil, and (C) a hydrocarbon oil, and the second-component composition contains (D) an anionic surfactant. [Effects of the Invention]

[0010] To provide a hair dye composition which has good usability when applied, spreads well on the hair when applied, leaves good finger-combability when rinsed off, leaves good hair condition after rinsing, and gives satisfactory hair dyeing. DETAILED DESCRIPTION OF THE INVENTION

[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 first agent composition of the hair dye composition according to the present invention contains (A) a cationic surfactant, which improves ease of application, spreadability, and compatibility with hair, enabling even dyeing of hair.

[0013] The cationic surfactant (A) used in the present invention is not particularly limited, but examples thereof include: Examples include behenyltrimethylammonium chloride, cetyltrimethylammonium chloride, stearyltrimethylammonium chloride, distearyldimethylammonium chloride, cetyltrimethylammonium bromide, stearyltrimethylammonium bromide, lanolin ethyl sulfate fatty acid aminopropylethyldimethylammonium, and stearic acid diethylaminoethylamide, and one or more selected from these may be contained.

[0019] By using the silicone oil (B) and the hydrocarbon oil (C) used in the present invention in combination, it is possible to obtain excellent finger-combability upon rinsing after dyeing and excellent hair condition after finishing, which could not be achieved by conventional general techniques.

[0020] The total amount of the silicone oil (B) and the hydrocarbon oil (C) used in the hair dye composition of the present invention is preferably 0.33 to 3%, more preferably 0.73 to 2.33%. If the total amount of the silicone oil (B) and the hydrocarbon oil (C) is less than 0.33% or more than 3%, the hair may become difficult to run your fingers through when rinsing after dyeing, and the finished hair may feel dry and sticky.

[0021] The mass ratio (C) / (B) of the contents of the silicone oil (B) and the hydrocarbon oil (C) used in the present invention is not particularly limited, but from the viewpoint of the ease of running fingers through the hair when rinsing after dyeing and the condition of the finished hair, it is preferably in the range of 0.7 to 2, more preferably 1.2 to 1.8. If the mass ratio (C) / (B) of the contents of the silicone oil (B) and the hydrocarbon oil (C) is less than 0.7 or exceeds 2, the hair may become difficult to run fingers through when rinsing after dyeing, and the finished hair may feel dry and sticky.

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

Among these, monoethanolamine and aqueous ammonia are preferred from the viewpoint of bleaching and hair dyeing effects.

[0027] The content of the alkaline agent in the hair dye composition of the present invention is preferably 0.1 to 3.33%. If the content of the alkaline agent is less than 0.1%, sufficient bleaching and hair dyeing effects may not be obtained. If the content exceeds 3.33%, significant damage to hair may occur.

[0028] The second part composition of the hair dye composition according to the present invention contains (D) an anionic surfactant, which improves ease of application, spreadability, and compatibility with hair, enabling even dyeing of hair.

Among these, hydrogen peroxide is preferred from the viewpoint of bleaching power.

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

[0034] The cationic surfactant (A) and the anionic surfactant (D) used in the present invention may aggregate and become unstable over time if they are mixed in the same formulation. Therefore, it is preferable to mix them in separate compositions and mix them together at the time of use to thicken them.
