Description

The present invention relates to a hair dye composition having a low irritating odor and excellent hair decolorizing power and hair dyeing power.

二 As a hair dye, a two-part type consisting of a first part containing an alkaline agent and a second part containing an oxidizing agent is widely used. The first alkaline agent is used to enhance the bleaching and hair dyeing effects, activate the oxidizing agent, promote the oxidative decomposition of melanin granules in the hair, and obtain a bright color tone. . In order to decolor and dye hair to a lighter color than the ground color, sufficient decoloring power is required, 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 has been generally used as an alkaline agent. However, ammonia has a strong pungent odor, and has the disadvantage of being accompanied by considerable discomfort during the treatment.

た め Therefore, attempts have been made to use organic amines having a low pungent odor instead of ammonia (Patent Documents 1, 2, 3, etc.). However, in these cases, there is a problem that hair cannot be decolorized to a sufficiently bright color, and when used in a large amount, the hair remains relatively high on the scalp, so that it is easy to apply irritation. .

処理 In addition, when hair is treated with these agents, the hair is damaged, the suppleness of the hair is lost, and there is also a problem that the hair becomes stiff and the comb is poor.

JP-A-59-106413 JP-A 1-213220 JP-A-5-246827

An object of the present invention is to have excellent bleaching power, and to be able to uniformly dye the color tone of the hair into a bright and good color, and furthermore, have less pungent odor, less irritation to the scalp, and less damage to the hair.
