Description

  The present invention relates to a hair dye composition that has little irritating odor, is excellent in hair conditioning effects during and after treatment, and is excellent in hair decolorization and hair coloring.

  As the hair dye, a two-component permanent hair dye 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 less irritating odors instead of ammonia (Patent Documents 1 to 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.

  The object of the present invention is to have excellent depigmenting power, to be able to evenly dye the color of the hair brightly and in good shades, to have less irritating odor, to less irritation to the scalp, and to effect hair conditioning An object of the present invention is to provide a hair dye composition excellent in hair bleaching and dyeing.

  The present inventor has found that the above problems can be solved by incorporating a specific amount of a specific organic solvent together with a cationic surfactant in the hair dye and keeping the water content within a specific range.

In the composition used by mixing the first agent containing an alkaline agent and the second agent containing an oxidizing agent, the present invention includes the following components (A) to (E):

Therefore, the amount of the alkaline agent can be further reduced without degrading the performance, and the irritating odor, hair damage, scalp irritation and the like can be reduced. In addition, it is effective in the case where the demand for hair is increasing in recent years and the hair mixed with gray hair is shaded brightly while the hair is dyed so as to be assimilated with the color of the whole hair. In addition, it is possible to uniformly dye a portion chemically treated with a hair permanent or the like and an untreated portion without any difference.
