Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD [0001] The present invention has a low irritating odor,
It is hypoallergenic and can lighten the hair in a short time without causing dripping from the hair, or can dye hair from a light color to a deep color well, and the obtained color has good color retention. Regarding the treatment agent.

[0002]

2. Description of the Related Art In recent years, there has been a growing demand from consumers for dyeing lighter shades than their original hair color (ground hair), and many so-called "fashion dyeing" products have been put on the market. The hair bleaching agent or hair coloring agent used for such a purpose is composed of a first agent containing an alkaline agent and a second agent containing an oxidizing agent. The alkali agent is compounded to enhance the bleaching or hair dyeing effect and to obtain a wide range of shades from a bright shade to a deep shade.
Particularly, in order to make hair lighter in color than ground hair, a sufficient decolorizing power is required. Therefore, when used for such a purpose, a particularly sufficient amount of alkali is required. In addition, in order to dye hair well with good color,
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 the disadvantage that consumers have considerable discomfort during treatment. Therefore, a method of dyeing hair using a carbonate with low odor as an alkaline agent instead of ammonia is disclosed in JP-A-63-139115, JP-A-6-279246, and the like. However, the alkaline agents used in these methods do not have sufficient decolorizing power and do not allow hair to be dyed in a bright shade because the amount of alkali is insufficient. In addition, the dyeing power is not sufficient, and it is difficult to dye hair into a deep color.

[0004]

SUMMARY OF THE INVENTION An object of the present invention is to reduce the irritating odor, to have low irritation, not to cause dripping from the hair, to make the hair a light color in a short time, or to have a deep color from a light color. It is an object of the present invention to provide a hair treatment agent which can satisfactorily dye up to a hue, and which has good color retention of the obtained color tone.

[0005]

Means for Solving the Problems The present inventors have found that if ammonia, ammonium salt and carbonate are combined in a specific ratio and the viscosity at the time of use is adjusted, the irritating smell of ammonia is small and the hair from the hair is reduced. The present inventors have found that a hair treatment agent that has solved the above-mentioned problems without any droplets can be obtained.

That is, the present invention relates to (A) ammonia,
It contains (B) ammonium salt and (C) carbonate, and (component (A) + component (B)) / component (C) [molar ratio] is 0.
