Description

The present invention relates to a hair dye composition.

Conventionally, as a hair dye composition, one that exerts an effect by using a plurality of agents in a mixed manner is known. For example, a hair dye composition composed of a first agent composition containing an oxidizing dye and an alkaline agent and a second agent composition containing an oxidizing agent is known. The alkaline agent activates the action of the oxidizing agent to promote the decomposition of the melanin pigment in the hair, and swells the hair to improve the permeability of the dye into the hair. Oxidizing agents are involved not only in the decomposition of melanin pigments but also in the color development of oxidative dyes.

As a generally well-known type of hair dye composition, the same amount of each of the creamy first agent composition and the second agent composition is discharged into a tray-shaped container and mixed for use. Add the entire amount of the creamy first agent composition to a bottle filled with a cream type, milky liquid or liquid second agent composition, and mix by shaking to mix using a brush-type nozzle. A milky lotion type foam that dyes hair, an aerosol type foam that is used by mixing the first agent composition and the second agent composition that are discharged in the form of bubbles by forming bubbles using an aerosol using a propellant such as liquefied gas. Use by adding the entire amount of the liquid first agent composition to a non-aerosol former container such as a pump former or squeeze former filled with a type or liquid second agent composition to form bubbles that take in air. There are non-aerosol type foam type and so on.

The cream-type hair dye composition can be set aside and only the part of the root that is of concern can be dyed each time, but since many use a brush, it should be applied well to the inside of the hair. It may not be possible and it may become uneven. Since many emulsion-type products are applied using a brush-type nozzle, it is necessary to impart a certain degree of softness to the hair dye composition, and although it fits well to the hair, be careful of dripping and splattering. Is required. The foam type can be easily dyed even by beginners because it is rubbed by hand like shampooing, but the hair dye composition is bulky and the amount to be picked up at one time is practically large. Because the amount of hair is reduced, the dyed finish tends to be uneven and may not be satisfactory.

Many of these types are specialized in usability during hair dyeing, and there are concerns about finger passage during hair rinsing after hair dyeing and the condition of the hair after finishing. Therefore, in recent years, the hair dye composition has good usability at the time of application, excellent spreadability at the time of application and familiarity with the hair, good finger passage at the time of rinsing and good condition of the hair after finishing, and satisfactory hair dyeing. Things are sought after.

For example, as a hair dye composition to be applied by hand, a composition that imparts a viscosity that does not drip when applied to hair by combining a specific nonionic surfactant (Patent Documents 1 and 2). Also, those that form high-quality bubbles have been studied (Patent Document 3).

Japanese Unexamined Patent Publication No. 2013-181032 Japanese Unexamined Patent Publication No. 2013-93855 Japanese Unexamined Patent Publication No. 2012-31072

However, in order to impart a viscosity that does not drip when applied by hand and to form high-quality foam, it is necessary to add a large amount of surfactant to the hair dye composition. By blending a large amount of surfactant, the degreasing power to the hair becomes too strong, the finger passage when washing off the hair dye composition becomes difficult, and dissatisfaction such as dryness remains on the finished hair. There was a problem. Therefore, it is very difficult to maintain good usability and high hair dyeing power while maintaining good finger passage during rinsing and hair condition after finishing, and there is still room for improvement.

As a result of diligent studies to solve the above problems, the present inventor has at least a first agent composition containing an alkaline agent and a second agent composition containing an oxidizing agent, and they are mixed and used at the time of use. A hair dye composition, wherein the first agent composition contains (A) a cationic surfactant, (B) a silicone oil, and (C) a hydrocarbon oil, and the second agent composition contains. (D) It has been found that a hair dye composition characterized by containing an anionic surfactant can be provided.

According to the present invention, the hair dye composition has good usability at the time of application, excellent spreadability at the time of application and familiarity with the hair, good finger passage at the time of rinsing and good condition of the hair after finishing, and satisfactory hair dyeing.
