BACKGROUND OF THE INVENTION Generally,
Oxidative hair dye is composed of an oxidation dye (first agent) and an oxidizer (second agent)
Are mixed and reacted at the time of use, and act on the head hair to dye gray hair.

In this case, the first agent contains an oxidation dye such as paraphenylenediamine and paraaminophenol, and its liquidity is generally alkaline. For this reason, there has been a problem that skin irritation to the scalp is caused by alkali.

On the other hand, as the second agent, hydrogen peroxide has been mainly used as an oxidizing agent. However, this hydrogen peroxide is known to cause damage to hair, causing damage to hair due to long-term continuous use,
It is known that after dyeing, the hair has a bad effect such as reddish brown hair.

[0005] So far, the first agent has been
Studies have been made on the neutralization of liquids (JP-A-8-217652).
As for the second agent, a technique using an oxidase instead of hydrogen peroxide has been proposed in an attempt to reduce damage to hair caused by hydrogen peroxide. Examples of such techniques include those using peroxidase as an oxidase (Japanese Patent Application Laid-Open Nos. 47-10400 and 53-32132) and those using laccase (U.S. Pat. No. 3,251,742; 6-17214
No. 5), those using uricase (JP-A-63-2)
No. 46313).

[0006] However, no proposal has been found in consideration of the usability at the time of hair dyeing. In particular, it is very problematic that a liquid dries during application and stains clothes and floors. Was required.

The present invention has been made in view of the above circumstances, and has as its object to provide a hair dye composition which is easy to apply to hair and has excellent hair dyeing properties.
