Description

The present invention relates to a hair dye composition.

Generally, hair dyes, decoloring agents, decoloring agents, decoloring / decoloring agents and the like are known as hair dyeing or decoloring agents, and are prepared by mixing two or more types of agents at the time of use. The As a composition for dyeing or decoloring hair, there are a first agent composition containing an oxidative dye and a second agent composition containing an oxidizer according to the alkaline agent and application, and these are mixed at the time of use. A hair coloring or decoloring composition is prepared and applied to the hair. The hair dye or depigmenting agent composition penetrates into the hair by opening the cuticle on the hair surface with an alkaline agent. The hair dye or depigmenting composition that has penetrated into the hair oxidizes and decomposes the melanin pigment that the hair itself has with an oxidizer, chemically reacts (oxidation polymerization) the oxidative dye in the hair, forms a pigment, and is fixed inside the hair To dye the hair.

As described above, the hair dye composition is used by adjusting the content of the alkali agent and the oxidizing agent in order to improve the dyeability. However, when the alkali agent and the oxidizing agent are used, the hair damage is not a little. For this reason, hair feel may be reduced. In addition, some of the alkaline agents used in the hair dyeing or decoloring composition have a very strong irritating odor, which may be painful when a customer dyes hair.

Various techniques have been disclosed to solve the above problems.

As a technique for improving the feel of hair by hair dyeing, it contains a silicone, a higher alcohol, a nonionic surfactant, a cationic surfactant and a higher fatty acid, thereby improving the feel of hair. The technology is disclosed. (Patent Document 1)

In addition, as a technique for improving the irritating odor, by setting the ratio of the predetermined component for stimulating the olfaction to be less than the perception limit on the olfaction, an odorless type hair treatment composition with little damage to the hair can be obtained. Techniques for agent compositions are 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 Patent Document 1 or 2, the hair dye composition is improved in the hair, but the hair dye is improved. The composition is less likely to stay on the hair, and the hair dye composition may sag from the hair. On the other hand, when the viscosity of the hair dye composition is set high, the hair stays firmly on the hair, but the hair spreads poorly and becomes difficult to apply.

Therefore, as a technique relating to hair coatability, a technique for hair cosmetics combining an amine oxide group-containing resin and a carboxyl group-containing thickening polymer is disclosed. (Patent Document 3) By using this technique, a hair cosmetic composition having high thixotropic properties and good stretchability for hair can be obtained.

However, when the amine oxide group-containing resin and carboxyl group-containing thickening polymer described in Patent Document 3 are used as a hair dye, the emulsion is stabilized by the alkali agent of the first agent composition or the oxidizing agent of the second agent composition. Sex may be impaired. Therefore, in order to maintain the emulsion stability without depending on the amine oxide group-containing resin and the carboxyl group-containing thickening polymer, it is generally used in the hair dye composition, and the alkali agent, the first agent composition, There is a demand for a technique for improving the spread of a hair dye composition on the hair using a component that is stable with respect to the oxidizing agent of the two-component composition.
