JP7064747B2 - Hair dye composition - Google Patents

Description

The present invention relates to a hair dye composition.

Hair dyeing compositions are roughly classified into permanent hair dyes such as oxidative hair dyes using oxidative dyes, semi-permanent hair dyes using direct dyes, and temporary colorants using pigments and the like. Of these, the hair dyeability of the semi-permanent hair dye is lower than that of the permanent hair dye because no alkaline agent or oxidizing agent is used, but the damage to the hair is small. On the other hand, although the oxidative hair dye has high hair dyeability, the damage to the hair is higher than that of the semi-permanent hair dye. Due to these differences, the demand for color treatment, which is one of the semi-permanent hair dyes, is increasing in the market as a coloring agent that is used repeatedly.

There are variations of color treatments, such as for bright hair, which is generally called fashion dyeing, and for gray hair, which is called gray hair dyeing. Therefore, there are a wide variety of coat colors required in the market, such as blue, red, and yellow, which are close to the primary colors, and brown and black, which have low saturation and lightness.

In general, color treatments impart treatment properties to hair. For example, it may contain a cationic surfactant or a cationic polymer in order to give a light texture. In addition, it may contain an oily component in order to give good finger passage and gloss.

And the color treatment contains the dye directly. Among the direct dyes, basic dyes and HC dyes, which do not easily deteriorate the hair dyeing property even when used in combination with a component that imparts treatment property, are mainly used.

For example, in order to achieve both hair dyeing ability and improvement of finger passage during hair drying, Patent Document 1 proposes a combination of a liquid ester oil, an alkylamidoamine and a salt thereof. Further, Patent Document 2 proposes a combination with an amine compound, α-hydroxy acid, silicone and a silicone derivative.
