Description

  The present invention relates to a hair dye composition that has little irritating odor and is excellent in hair decoloring ability and hair coloring ability.

  As the hair dye, a two-component type comprising a first agent containing an alkaline agent and a second agent containing an oxidizing agent is widely used. The alkaline agent of the first agent is blended in order to enhance the decolorization and hair dyeing effects, and to activate the action of the oxidizing agent to advance the oxidative degradation of the melanin granules in the hair, thereby obtaining a bright color tone. . Sufficient depigmenting power is required to decolorize and dye hair in a lighter color than the ground color, but since hair decoloring power generally depends on the amount of alkali, when used for such purposes, In particular, a sufficient amount of alkali is required.

  Conventionally, ammonia is generally used as an alkaline agent. However, ammonia has a strong pungent odor and has the disadvantage that it is accompanied by considerable discomfort during treatment.

  For this reason, attempts have been made to use organic amines with little irritating odor in place of ammonia (Patent Documents 1, 2, 3, etc.). However, in these cases, there is a problem that the hair cannot be decolored to a sufficiently bright color, and when used in a large amount, the remaining on the scalp is relatively high, so that it is easy to give irritation. .

  In addition, when the hair is treated with these agents, the hair is damaged, the hair is not supple, the hair becomes crunchy, and the combing property is deteriorated.

  It is an object of the present invention to have excellent depigmenting power, to be able to evenly dye the color of hair in a bright and good shade, to have less irritating odor, low irritation to the scalp, and to damage hair. An object of the present invention is to provide a hair dye composition that is excellent in hair decolorization and dyeing.

  The present inventor has found that the above-mentioned problems can be solved by including a specific organic solvent and a specific polyoxyalkylene glycol derivative in the aqueous hair dye composition.
