Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention can lighten the color tone of hair and dye it into a good color in a short time, and have high fastness to shampoos, etc., good color retention, and a pungent odor. The present invention relates to a hair treatment composition which is extremely low and has low irritation to the scalp.

[0002]

2. Description of the Related Art Oxidative hair bleaching agents or hair coloring agents include the following.
An alkaline agent is blended in the agent. The alkaline agent is added to enhance the bleaching or hair dyeing effect and to promote the oxidative decomposition of melanin granules in the hair to obtain a bright color tone. In order to bleach or dye hair in a lighter shade than ground hair, the hair treatment agent must have sufficient hair bleaching power, but since the bleaching power generally depends on the amount of alkali, it is used for such a purpose. If you do
In particular, a sufficient amount of alkali is required.

Conventionally, ammonia has been generally used as an alkaline agent. However, ammonia has a strong irritating odor, and has a major drawback that consumers have considerable discomfort during the treatment.

For this reason, attempts have been made to use organic amines having a low odor instead of ammonia (JP-A-59-106413, JP-A-1-213322).
0, JP-A-5-246827, etc.). However, organic amines have insufficient bleaching power, cannot bleach or dye hair in a bright color, and when used in large amounts, have high persistence on the scalp, causing discomfort and irritation. There is a problem of giving. In addition, Japanese Unexamined Patent Publication
No. 287521 describes that hair can be dyed in a bright color using a water-soluble dye.
There was a problem that the fastness to shampoo and the like was low and the color durability was poor.

[0005]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a hair with a sufficient decoloring power to lighten the color tone of the hair or to dye the hair in a good color, and has a high fastness to shampoos and the like. An object of the present invention is to provide a hair treatment composition which has good color durability, has little irritating odor, and has low irritation to the scalp.

[0006]

Under such circumstances, the present inventors have conducted intensive studies and as a result, it has been found that the use of a combination of an alkali agent and a specific aromatic alcohol can lighten the color tone of hair in a short time. Or, it can be dyed in a good color, and has high fastness to shampoo, etc.
The present inventors have found that a hair treatment composition having good color, very little pungent odor, and low irritation to the scalp can be obtained, and completed the present invention.

That is, the present invention provides (a) an alkali agent,
And (b) general formula (1)
