Description

  The present invention relates to a decolorization aid and a decolorization agent, and more particularly to a decolorization aid and a decolorization agent that have greatly improved damage (damage) to hair.

  Conventionally, (body hair) depigmenting agents have been widely used. The depigmenting agent removes the original color (melanin pigment) of body hair, and at present, the decoloring agent is widely used together with the dyeing agent. In particular, hair dyes (materials) are used in accordance with individual styles, designs, and preferences as they can dye body hair (especially, hair and wrinkles) in various colors. For this reason, a taster may desire a dyeing means with higher dyeability when dyeing various colors, and a decoloring agent is often used before dyeing. By removing the melanin pigment from the body hair with the decolorizing agent, it is possible to achieve the staining power, the fixing rate, etc. of the staining agent when the hair is subsequently dyed using the staining agent.

  However, since the depigmenting agent decolorizes and removes the melanin pigment originally provided in the body hair, it will cause significant damage to the body hair and may inhibit the original function of the body hair. Therefore, it is not preferable to use a decoloring agent frequently. Moreover, the decoloring agent is generally composed of a first agent containing an alkali agent and a persulfate and a second agent containing hydrogen peroxide. However, when these agents are used on body hair, not only the body hair but also the skin may be damaged, and itching, itching, and allergic dermatitis may occur. For this reason, it is desired to be a decolorizing agent prepared with sufficient consideration for the animals (including humans) to be decolorized and the body of the practitioner performing decoloring, in particular, fingers, hands, arms, and the like. Further, many alkali agents and peroxides are not excellent in storage stability and cannot realize long-term reaction stability.

  On the other hand, in order to improve the storage stability, according to Patent Document 1 (Japanese Patent Application Laid-Open No. 2015-17138), it is proposed to use a phosphate in a medicine containing a carbonated ammonium salt. Yes. Moreover, in patent document 2 (Unexamined-Japanese-Patent No. 2012-167054), in the hair treatment agent used as a hair dye or a hair decoloring agent provided with the 1st agent containing an alkaline agent and the 2nd agent with which the oxidizing agent was mix | blended, The pH of one agent is set to less than 9.8, and further, a carbonate ammonium salt and a phosphate ammonium salt are added to the first agent, and the compounding concentration of the carbonate ammonium salt in the first agent is 7. What was made less than 5 mass% is proposed.

  However, according to the study by the present inventors, in the decoloring agent constituted by the first agent containing the alkali agent and persulfate and the second agent containing hydrogen peroxide, There is no one that can sufficiently suppress damage to body hair and skin, and it has been recognized that there is still a need for improvement in this respect.

  Therefore, the present inventors have used a novel decolorization aid that can greatly improve the damage to hair and skin that occurs when using a decoloring agent while maintaining the decoloring power in the decoloring agent. He recognized that the development of depigmenting agents was extremely necessary.

Japanese Patent Laying-Open No. 2015-17138 JP 2012-167054 A

  By adopting magnesium (Mg) and / or calcium (Ca) oxides, the inventor damages the hair and skin to be decolorized and the body (especially the body skin) to be decolorized. In addition, the present inventors have found that a decoloring aid capable of performing sufficient decolorization and a decoloring agent using the same can be proposed. The present invention has been made based on such findings.

Therefore, the decoloring aid proposed by the present invention is:
Used for depigmenting agents,

Specific embodiments for carrying out the invention

[Definition]
“Decolorization aid” is used for the purpose of decolorization and suppresses the rapid decolorization caused by the decolorization agent and exerts the function of mitigating irritation and damage to body hair and skin. As an agent, it is used as an auxiliary agent included in a decoloring agent or as an auxiliary agent which is a component of a decoloring set.
The “depigmenting agent” is an agent mainly used for decolorizing by decomposing melanin, which is a pigment of body hair, and is also called “hair bleach, hair lightener” or the like.
“Decoloring agent” is an agent used mainly for the purpose of removing the coloring agent (dyeing agent) applied to the hair rather than decolorizing the pigment inherent in the body hair (particularly melanin pigment). is there. Therefore, in this sense, the “decoloring agent” is separated from the “decoloring agent”.
