中に残存する染料を分解する脱染の働きを有する。BACKGROUND OF THE INVENTION Conventionally, as a hair bleaching agent, a two-pack type hair bleaching agent is known in which a first agent containing an alkaline agent and a second agent containing an oxidizing agent are mixed just before the treatment. ing. Creams, liquids, and powders are known as such a first agent. Particularly, when the first agent is a powder, the first agent is oxidized in order to enhance the decolorizing power. It is widely practiced to add persulfate as an agent. Persulfate decomposes melanin in the hair to decolorize the hair itself and also dyes hair that has been dyed in the past (hereinafter referred to as dyed hair).
It has the function of decontamination that decomposes the dye that remains inside.
【０００３】ところで、このような２剤型の毛髪脱色剤
を使用する場合には、毛髪の根元部分の温度が体温に近
いのに対し、毛先部分が外気温に近いため、温度の高い
根元部分が強く脱色され、毛髪の根元から毛先まで均一

得ようとする場合は、温度の影響による毛髪脱色力を調
節するために、脱色剤を先に温度の低い毛先部分に塗布
し、一定時間をおいてから温度の高い根元部分に塗布す
るといった操作が必要であり、煩雑であった。By the way, when such a two-component type hair bleaching agent is used, the temperature at the root of the hair is close to the body temperature, whereas the temperature at the tip of the hair is close to the outside temperature, so that the root having a high temperature is used. There is a problem that the part is strongly decolorized, and it is difficult to uniformly decolorize the hair from the root to the hair tips. Therefore, in order to obtain a uniform finish using such a hair bleaching agent, in order to adjust the hair bleaching power due to the influence of temperature, the bleaching agent is first applied to the low temperature end portion. However, it was complicated because it required an operation of applying it to the root portion having a high temperature after a certain period of time.
【０００４】また、既染毛部と新生毛部とが混在する毛
髪を脱色する場合にも、既染毛部は既に脱色されてお
り、脱色する必要がなく、残留している染料を脱染すれ

分解して脱色する必要がある。したがって、この場合に
も、脱色剤を先に新生毛部分に塗布し、一定時間をおい
てから、既染毛部分に塗布するといった操作が必要であ
り、煩雑であるという欠点があった。Further, when bleaching hair in which the dyed hair portion and the new hair portion are mixed, the dyed hair portion has already been bleached, and it is not necessary to bleach it, and the remaining dye is dyed. On the other hand, it is necessary to decompose melanin and decolorize the newly-grown hair part that has been elongated. Therefore, also in this case, it is necessary to apply the decolorizing agent to the new hair portion first, and after a certain period of time, to apply it to the already dyed hair portion, which is disadvantageous in that it is complicated.

が得られることを見出し、本発明を完成するに至った。Further, a decolorizing agent having a generally stronger decolorizing power,
There is a problem that the finish tends to be uneven due to variations in the coating time and the coating amount. That is, when a decolorizing agent having a strong decolorizing power is used, the decolorizing effect begins to appear in a very short time after coating, so that there is a problem that it is difficult to secure a uniform coating time and coating amount. The present inventors have conducted extensive studies in view of the above circumstances, and as a result, by using a powdery composition for hair bleaching containing a specific amount of a persulfate salt and an alkaline agent, depending on the state of hair, use The time required for decolorization after application can be controlled by adjusting the strength of the decolorizing agent to be applied, and the work efficiency can be improved by setting it as a set with a powdery composition for decolorizing hair of another composition. It was found that a hair depigmenting agent that is capable of decoloring uniformly and uniformly is obtained, and has completed the present invention.

Is a first agent for forming a two-component type hair bleaching agent with a second agent containing hydrogen peroxide, which is a powdery composition for hair bleaching containing a specific amount of a persulfate and an alkaline agent. It is characterized in that ammonium persulfate is contained as the persulfate in an amount equal to or less than a specific amount.

硫酸カリウム、過硫酸ナトリウムなどが挙げられる。Specifically, the powdery composition [I] is
The amount of the persulfate is usually 0.1 to 15% by weight, preferably 1 to 10% by weight, more preferably 3 to 8% by weight, when the total amount of the persulfate and the alkaline agent is 100% by weight. However, the amount of ammonium persulfate as the persulfate is preferably 0 to 3% by weight. That is, when the total amount of the persulfate and the alkaline agent is 100% by weight, ammonium persulfate may be contained as the persulfate in an amount of 3% by weight or less, but it is more preferable not to include ammonium persulfate. . In this case, other persulfate may be used in the powdery composition [I] so that the persulfate content becomes the above-mentioned amount. Specific examples of such other persulfates include potassium persulfate and sodium persulfate.

ことができる。Ammonium persulfate has a strong decolorizing power and decontaminating power among the persulfates. Therefore, while containing the persulfate, the ammonium persulfate content is suppressed to the utmost, and the above amount is obtained. It is possible to obtain a powdery composition for a decolorizing agent containing a persulfate having a low decolorizing power which has not been obtained. Such a powdery composition [I] having a low decolorizing power can be used as a decolorizing agent by blending a second agent described later, when the decolorizing power is not required so much, or in such a part alone. By mixing it with the powdery composition for hair bleaching having another composition, its strength and the time required for bleaching can be adjusted.
