BACKGROUND OF THE INVENTION
The present invention has little irritating odor, low irritation, can make hair light in a short time without causing droplets from the hair, and can be dyed well from light to deep tones. The present invention relates to a hair treatment agent having good color tone.
[0002]
[Prior art]
In recent years, there has been an increase in consumer demand for a lighter shade than their original hair color (ground hair), and many so-called “fashion dyes” are now on the market. The hair bleaching agent or hair dye used for such a purpose is composed of a first agent containing an alkaline agent and a second agent containing an oxidizing agent. The alkaline agent is blended in order to enhance the decoloring or hair dyeing effect and obtain a wide range of shades from bright shades to deep shades. In particular, in order to make the hair a lighter color than the ground hair, a sufficient decoloring power is required. Therefore, when used for such purposes, a particularly sufficient amount of alkali is required. In addition, a sufficient amount of alkali is necessary to dye the hair with good color and firmness.
[0003]
Conventionally, ammonia is generally used as an alkaline agent. However, ammonia has a strong pungent odor and has the disadvantage that consumers have considerable discomfort during treatment.
In view of this, methods for dyeing hair using a carbonate having a low odor instead of ammonia as an alkaline agent are disclosed in JP-A-63-139115 and JP-A-6-279246.
However, the alkali agents used in these methods do not have a sufficient decolorizing power because the amount of alkali is not sufficient, and the hair cannot be dyed in a light shade. Moreover, it cannot be said that the dyeing power is sufficient, and it is difficult to dye the hair into a deep shade.
[0004]
[Problems to be solved by the invention]
The object of the present invention is low irritating odor, low irritation, does not cause droplets from the hair, can make hair bright in a short time, or can be dyed well from light to deep, Moreover, the object is to provide a hair treatment agent with good color tone.
[0005]
[Means for Solving the Problems]
The present inventors combined ammonia, ammonium salt, and carbonate at a specific ratio, and adjusted the viscosity at the time of use, so that the irritating odor of ammonia is small, there is no droplet from the hair, and the above problems are solved. It has been found that a resolved hair treatment agent can be obtained.
