Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a hair dye composition, and more particularly, the present invention relates to a hair dye composition containing a specific surfactant and capable of dyeing hair in a deep tone. The present invention relates to a hair dye composition.

[Prior art] Generally speaking, oxidative hair dyes containing paraphenylenediamine and 2,5-diaminotoluene, and non-oxidizing hair dyes containing acid dyes are commonly used. used.

From the viewpoint of color retention, the former is called a permanent hair dye, and the latter is called a semi-permanent hair dye.

These hair dyes are commonly used to color the hair to make it less noticeable for people with gray hair, or to give a more feminine look to people with dark hair. be. However, with conventional hair dye technology, in order to obtain a sufficient dyeing effect, it was necessary to increase the dye concentration, increase the treatment temperature (or increase the treatment time). For safety reasons, for example, if paraphenylenediamine or an oxidative dye with a similar structure is used, it is undesirable to increase sensitization.It is also undesirable to raise the treatment temperature or lengthen the treatment time. It was not desirable to do so because it was uncomfortable and time consuming in actual use.

With acidic hair dyes, the amount of dye that can be adsorbed onto the hair is limited, so even if the dye concentration, treatment temperature, and treatment time are increased, a satisfactory dyeing power cannot be obtained.

[Problems to be Solved by the Invention] The present inventors have discovered that the dye concentration in the composition, the treatment time, the treatment temperature are not increased or the treatment temperature is increased, and the hair dyeing ability is excellent, and the hair is dyed after coloring. As a result of intensive research to obtain a hair dye that can add depth to the color tone, we have developed a hair dye composition that significantly improves the drawbacks of conventional hair dye compositions by incorporating a specific surfactant into the hair dye composition. The present inventors have discovered that the following can be obtained, and have completed the present invention.
