  However, in general, a conventional decoloring / destaining agent composition often causes decoloring / destaining unevenness, and it is often difficult to uniformly decolorize / destain. On the other hand, when metasilicate is used as an alkaline agent in order to enhance decolorization and decoloring power, there is also a problem that the feel of hair is considerably deteriorated. On the other hand, in the decoloring / destaining agent composition that contains an alkaline agent such as carbonate instead of metasilicate, a significant deterioration in hair feel can be prevented, but a large amount of carbonate etc. is added to increase the decoloring power. By blending, the mixing property with the second agent containing hydrogen peroxide was lowered, and as a result, there was a strong tendency to cause decoloration / decoloration unevenness.

  Therefore, the present invention provides a decoloring / destaining agent composition that has good mixing properties of each agent constituting the decoloring / destaining agent, can ensure uniform decoloring / destaining properties on the hair, and also has a good finish on the feel of the hair. Providing is a technical problem to be solved.

  The inventor of the present application blends a specific alkaline agent such as carbonate in addition to persulfate in the decolorization / destaining agent composition, and further blends a certain amount of starch, so that the mixing property of each agent is remarkable. It has been found that uniform decolorization / decoloring property for hair is ensured and the feel of the hair after finishing is improved.

(First invention)
The configuration of the first invention of the present application for solving the above-mentioned problem is configured to include a first agent and a second agent mixed and prepared at the time of use, and the first agent is composed of the following components (A) to (C): A decolorizing / destaining agent composition, wherein the second agent contains hydrogen peroxide.
(A) One or more types of starch. (A) Content at the time of mixing preparation of a component exists in the range of 1.0-20 mass%.
(B) One or more persulfates.
(C) One or more alkali agents other than the component (B). (C) Content at the time of mixing preparation of the component is in the range of 0.5 to 10% by mass, and 95 parts by mass or more in 100 parts by mass of (C) component is carbonate, phosphate and basic amino acid. It is occupied by one or more alkali agents selected from:

  In relation to the first invention described above, the inventor of the present application provides the mixing ability of the first agent and the second agent because the water-holding power of starch imparts an appropriate viscosity / viscosity to the decolorizing / destaining agent composition. Found to improve. In addition, since starch has an action of preventing liquid thirst when applied to hair, it has an effect of increasing the uniformity of decolorization / decoloration without impairing the penetration effect of active ingredients during treatment. Furthermore, since starch has an action of mitigating the penetration of the components of the decoloring / destaining agent composition into the hair, it is possible to minimize damage and improve touch.

As a result, in the decoloring / destaining agent composition containing an effective amount of starch, the mixing property of each agent constituting the decoloring / destaining agent is good, and uniform decoloring / destaining properties for the hair can be ensured. In particular, when persulfate (B) component or carbonate (C) component is blended, especially when a large amount of carbonate (C) component is blended in order to enhance decoloring power, these Characteristics are ensured. Furthermore, the feel of the hair after finishing is improved. The starch in the decoloring / destaining agent composition is blended with the first agent so that the content at the time of mixing and preparation is in the range of 1.0 to 20% by mass. . In addition, in this invention, "content at the time of mixing preparation" is mixing each agent (1st agent and 2nd agent, or 1st agent-3rd agent etc.) which comprises a decoloring and decoloring agent composition. The content in the prepared state. If the starch content is less than 1.0% by mass at the time of mixing preparation, the effect of improving the mixing properties of the first agent and the second agent is insufficient. Even if the starch content exceeds 20% by mass at the time of mixing preparation, while the blending effect of starch is saturated, the blending ratio of other active ingredients is reduced as a result, and sufficient decolorization and decoloring performance is obtained. I can't.

  Further, the decolorizing / destaining agent composition contains a predetermined amount of an alkali agent other than persulfate as the component (C), and more than 95 parts by mass in 100 parts by mass of the component (C) are carbonates and phosphates. And one or more alkaline agents selected from basic amino acids, so that the above-mentioned effects due to the blending of starch are ensured, and decolorization and decoloration performance are also ensured while preventing deterioration of the feel of hair. .

  If one or more alkali agents selected from carbonates, phosphates and basic amino acids are less than 95 parts by mass in 100 parts by mass of component (C), the effects of the present invention are not ensured. For example, when 5 parts by mass or more of 100 parts by mass of component (C) is occupied by metasilicate, even if the decolorization / decoloration performance is exhibited, the hair feel is considerably deteriorated even in the presence of starch. The effect of the present invention cannot be realized.

  (C) A component is mix | blended with a 1st agent so that content at the time of mixing preparation may be in the range of 0.5-10 mass%. When the content of the component (C) is less than 0.5% by mass at the time of mixing preparation, the decolorization / decolorization performance of the decolorization / decoloring agent composition cannot be sufficiently obtained. When the content of the component (C) exceeds 10% by mass at the time of mixing and preparing, the damage to the hair increases beyond the allowable range.

(Second invention)
The structure of the second invention of the present application for solving the above-mentioned problems is that the decolorization / destaining agent composition according to the first invention is a persulfate as the component (B), a carbonate as the component (C) and phosphoric acid. It is a decoloring / destaining agent composition in which each salt is an alkali metal salt.

  The types of the persulfate as the component (B), the carbonate and the phosphate as the component (C) of the decolorizing / destaining agent composition are not necessarily limited, but as in the second invention, these salts are each An alkali metal salt is preferred.

(D) One or more cationic polymer compounds.

  If the decolorizing / destaining agent composition further contains a cationic polymer compound as the component (D) as in the third invention, the feel of the hair after the decoloring / destaining treatment is further improved.

(Fourth invention)
The constitution of the fourth invention of the present application for solving the above-mentioned problems is that the content of hydrogen peroxide in the decolorizing / destaining agent composition according to any one of the first to third inventions at the time of mixing preparation is 3.0. It is a decoloring / destaining agent composition that is not more than mass%.

  The content of hydrogen peroxide in the second agent of the decoloring / destaining agent composition is not necessarily limited, but from the viewpoint of reducing hair damage due to the decoloring / destaining treatment, as in the fourth invention, It is preferable to add hydrogen peroxide to the second agent so that the content is 3.0% by mass or less. In addition, when the content of hydrogen peroxide at the time of mixing preparation is 0.5% by mass or less, the decoloring / decoloring performance of the decoloring / destaining agent composition tends to be insufficient. On the other hand, if the content during mixing and preparation exceeds 3.0% by mass, damage to the hair tends to increase.

(Fifth invention)
The composition of the fifth invention of the present application for solving the above-mentioned problem is that the mixing ratio of the first agent and the second agent based on the mass of the decolorizing / destaining agent composition according to any one of the first to fourth inventions. Is in the range of 1:10 to 1: 2.

  The mixing ratio of the first agent and the second agent in the decoloring / destaining agent composition of the present invention is not particularly limited. For example, as in the fifth invention, the mixing ratio on the mass basis of the first agent: second agent Is preferably in the range of 1:10 to 1: 2.

  According to the decoloring / destaining agent composition of the present invention, the mixing property of each agent constituting the decoloring / destaining agent is good, and it is possible to ensure uniform decoloring / destaining properties on the hair, and further, after finishing the hair. The touch is also improved.

  Next, modes for carrying out the present invention will be described including the best mode.

[Decolorization / destaining agent composition]
The decoloring / destaining agent composition of the present invention is a treatment agent that decolorizes hair, decolors hair, or decolorizes and decolorizes hair.

In addition to these first and second agents, There are also cases where the third agent is mixed and prepared at the time of use, and is configured as a three-agent system including an agent having an arbitrary composition as long as the effects of the present invention are not impaired.

  The dosage form of the first agent and the second agent (or the third agent) is not necessarily limited. Usually, the first agent is powdery, granular, or tablet-like, and the second agent is liquid.

  The mixing ratio of these first agent and second agent (or further, third agent, etc.) at the time of mixing and preparation is not particularly limited. For example, in the two-component decoloring / destaining agent composition, the first agent and the second agent are mixed. The mixing ratio based on the mass of the agent is preferably in the range of 1:10 to 1: 2. The reason for this is that when the ratio of the second agent is increased from the range of the first agent: second agent = 1: 10, the viscosity / viscosity of the decoloring / destaining agent composition tends to become excessively low. This is because the mixing property of the agent and the second agent tends to deteriorate and is not preferable. In addition, if the ratio of the second agent is decreased from the range of the first agent: second agent = 1: 2, the viscosity / viscosity of the decoloring / destaining agent composition tends to be excessively increased. This is because the miscibility of the second agent tends to deteriorate.
