Description

The present invention relates to a hair dye composition.

Generally, as an agent for dyeing or bleaching hair, a hair dye, a bleaching agent, a bleaching agent, a bleaching / bleaching agent, etc. are known, and two or more kinds of agents are mixed at the time of use and prepared. To. As a composition for dyeing or bleaching hair, there are a first agent composition containing an alkaline agent and an oxidative dye depending on the intended use, and a second agent composition containing an oxidant agent, which are mixed at the time of use. It is used by formulating a hair dye or decolorizing agent composition and applying it to the hair. The hair dye or bleaching agent composition opens the cuticle on the surface of the hair with an alkaline agent and penetrates into the inside of the hair. The hair dye or decolorizing agent composition that has penetrated into the hair oxidatively decomposes the melanin pigment of the hair itself with an oxidizing agent, and chemically reacts (oxidatively polymerizes) the oxidizing dye in the hair to form the pigment and fix it inside the hair. The hair is dyed by letting it.

As described above, the hair dye composition is used by adjusting the content of the alkaline agent or the oxidizing agent in order to improve the dyeability, but when the alkaline agent or the oxidizing agent is used, damage to the hair is not a little. Therefore, the feel of the hair may be deteriorated. In addition, some of the alkaline agents used in the hair dyeing or bleaching agent composition have a very strong pungent odor, which may cause pain when the consumer dyes the hair.

Therefore, various techniques have been disclosed in order to solve the above problems.

As a technique for improving the feel of hair by dyeing hair, a hair dye composition that improves the feel of hair by containing silicone, a higher alcohol, a nonionic surfactant, a cationic surfactant, and a higher fatty acid. Technology is disclosed. (Patent Document 1)

In addition, as a technique for improving the irritating odor, by setting the ratio of the predetermined component that stimulates the sense of smell to be equal to or less than the sensing limit on the sense of smell, an odorless type hair treatment agent composition with less damage to the hair can be obtained. The technique of the agent composition is disclosed. (Patent Document 2)

However, when the viscosity of the hair dye composition is set low in order to improve the spread at the time of application from the above Patent Document 1 or 2, the hair dye composition spreads well to the hair, but the hair dye The composition may be difficult to stay on the hair, and the hair dye composition may hang down from the hair. On the other hand, when the viscosity of the hair dye composition is set high, it stays firmly on the hair, but it does not spread well to the hair and is difficult to apply.

Therefore, as a technique for applying hair, a technique for hair cosmetics in which an amine oxide group-containing resin and a carboxyl group-containing thickening polymer are combined is disclosed. (Patent Document 3) By using this technique, it is possible to obtain a hair cosmetic having high thixotropy and spreading well on hair.
