Description

  The present invention relates to an oxidizing agent composition. In more detail, the present invention always provides appropriate mixing and viscosity in the case of use in combination with the first agent of oxidative hair dyes and hair bleaching agents according to various dosage forms and formulation contents, and The present invention relates to an oxidizing agent composition that is low-irritant and can ensure stable hair dyeing power and bleaching power.

  There are many two-component oxidative hair dyes and hair bleaching agents that are mixed at the time of use. In a two-component oxidative hair dye, the first agent usually contains an oxidation dye and an alkaline agent as essential components, and the second agent contains an oxidant as essential components. In a two-component hair bleaching agent, the first agent usually contains an alkaline agent as an essential component, and the second agent contains an oxidizing agent as an essential component.

  The first agent in such a two-component oxidative hair dye or hair bleaching agent can be in various dosage forms such as powder, liquid, gel, cream, etc., depending on the purpose of use. In addition, prescription characteristics differ depending on the dosage form.

  On the other hand, the second agent of the oxidative hair dye and the hair bleaching agent is not necessarily sufficient if it simply contains an oxidant as described above, and in fact, the first agent relating to various dosage forms and prescription contents. Each drug must be formulated to match well. Otherwise, when the combination with the first agent is used, there is a problem in the mixing property between them, the viscosity suitable for application to the hair after mixing cannot be obtained, and further, the dyeing of the applied hair is performed. There is a problem that unevenness occurs in the hair effect or the bleaching effect.

  Under the circumstances as described above, conventionally, a dedicated second agent relating to a suitable prescription has been separately prepared for the first agent having various dosage forms and prescription contents. Therefore, the effort and cost burden for preparing the second agent are large.

  Such a problem is a configuration in which a hair treatment is added as a third agent to a two-component oxidative hair dye or a hair decoloring agent, or a third agent containing a booster (decoloring accelerator) is added. This was also observed in the three-part oxidative hair dyes and hair bleaching agents.

  Accordingly, the present invention provides an oxidant composition having a uniform composition that can be used in a uniform combination with the first agent of various dosage forms and prescriptions, and the mixing properties of the first agent and the second agent described above. The technical problem to be solved is to develop an oxidizer composition that does not cause problems in terms of viscosity after mixing, hair dyeing effect during application, bleaching effect, and the like.

  In the process of pursuing the means for solving the above technical problem, the inventor of the present application further blends a hardened castor oil fatty acid ester derivative and waxes with an oxidizing agent, and more preferably a liquid hydrocarbon at room temperature. It has been found that the above technical problem can be solved by blending at least one of the metal sequestering agent together.

  The inventor of the present application has never heard about the presentation of such technical problems and the configuration of the means for solving them. In some known documents such as the following Patent Documents 1 to 3, the technical problem of the present invention is not disclosed or suggested at all, but by chance, a part of the configuration of the solving means (configuration of the present invention) is fragmented Is disclosed.

In the case where the component (D) of the components (E) to (E) is not blended, there is a significant difference particularly in the evaluation items of “irritating odor” and “level dyeability”.

  (3) Even between the examples, both the case of Example 1 and the components (D) and (E) among the components (A) to (E) as in Example 7 In the case of not blending, a significant difference is clearly seen in the evaluation item of “level dyeability” more clearly than in the case of (2) above.

  The oxidizing agent composition of the present invention can be used in a uniform combination with respect to the first agent of various dosage forms and formulation contents, and the mixing property of the first agent and the second agent, the viscosity after mixing. No problems in terms of feeling during use, irritation, hair dyeing effect, bleaching effect, etc. occur.
