Description

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to an intermediate treatment agent for a two-bath permanent wave, an agent for a two-bath permanent wave and a two-bath permanent wave, which focuses on the importance of the intermediate treatment in the treatment of a two-bath permanent wave. Regarding processing method.

[0002]

2. Description of the Related Art In the two-bath type permanent wave treatment, basically, the first method containing at least a reducing agent is used.
The cystine bond (disulfide bond) of the hair protein is reductively cleaved by the agent, and then the cystine bond of the hair protein is oxidatively regenerated by a second agent containing at least an oxidizing agent after performing winding using an instrument. However, with only the above first and second agent treatments, the hair is considerably damaged by the severe treatment of reduction / oxidation, for example, the elasticity and strength of the hair are deteriorated, and the feel is deteriorated. May occur.

In order to cope with such a problem, in the middle of the treatment with the first agent and the treatment with the second agent, for the purpose of recovering damage to the hair or improving elasticity and feel of the hair,
It has been proposed to perform an intermediate treatment using an intermediate treatment agent having various compositions. On the other hand, various polymer compounds, surfactants and the like have been proposed as blending components for the first agent, the second agent or the intermediate treatment agent.

For example, in the permanent composition according to Japanese Patent Laid-Open No. 56-100710, the first agent contains a cationic polymer and the second agent contains an anionic surfactant. This cationic polymer is adsorbed on the hair to cover the damage and improve elasticity, and further,
It is expected that the effect of improving the feel of the hair (feeling of finger passage) by forming a complex with the anionic surfactant of the second agent.

The permanent wave intermediate treatment agent disclosed in JP-A-7-89829 contains triglyceride and a surfactant. Alkyl glucosides that can be expected to have a moisturizing effect are also disclosed in this surfactant.
It is considered that the surfactant can be expected to have the effect of improving the wettability of the hydrophobic surface of the hair with water and promoting the penetration of various components into the hair.

[0006]

However, JP-A-56-
In the composition for permanent according to 100710,
Since the cationic polymer is blended in the first agent and applied to the hair which is not yet sufficiently swollen, a sufficient amount of the cationic polymer may not be adsorbed to the hair. Therefore, the complex formation between the cationic polymer and the anionic surfactant as the second agent may be insufficiently completed. As a result, the effect of improving the elasticity of hair may be insufficient. Furthermore, when a cationic polymer is used as the first agent and an anionic surfactant is used as the second agent,
The feel of the finished hair is not always good.

On the other hand, when an intermediate treating agent contains a surfactant as in the invention disclosed in JP-A-7-89829,
The general effects of the above-mentioned surfactant can be expected. However, conventionally, it has been considered that the surfactant itself does not contribute to the improvement of the elasticity of the hair, and therefore, the formulation that the surfactant is blended with the intention of improving the elasticity of the hair has not been made.

In view of the above points, the present invention relates to a two-bath type permanent waving agent, in particular, by devising a specific combination of the intermediate treatment agent and the second agent for the hair. It has an excellent damage prevention effect and elasticity improvement effect, and also gives a good feel when finishing hair,
Further, it is a problem to be solved to provide a two-bath type permanent wave agent capable of enhancing the moisturizing effect of hair.

(Operation and Effect of First Invention) The intermediate treatment agent according to the first invention contains an anionized polymer compound and / or an anionic surfactant.

As will be described later, in the two-bath type permanent waving agent, it is preferable to add a cationized polymer compound and / or a cationic surfactant to the second agent in order to obtain a good feel of hair. It is particularly preferable because of (feeling of finger passage). Therefore, as the polymer compound and / or the surfactant to be blended in the intermediate treatment agent, an anionized polymer capable of forming a complex with the cationized polymer compound and / or the cationic surfactant of the second agent satisfactorily Compounds and / or anionic surfactants are particularly preferred. Therefore, the intermediate treatment agent according to the first invention is particularly excellent in the effect of improving the elasticity of hair and the feel at the time of finishing when combined with the second agent as described above.

Further, it has been found that in addition to the conventionally known effect of promoting the penetration of various components into the hair, the anionic surfactant can also contribute to the improvement of the elasticity of the hair. Therefore, the anionic surfactant can be expected to have the same effect as the anionized polymer compound.

(Structure of the Second Invention) The structure of the second invention of the present application (the invention according to claim 2) for solving the above-mentioned problems is as follows.

The feel can be realized. On the other hand, conventionally, it has been considered that a surfactant or a moisturizer has an irrelevant or negative effect on the effect on improving the elasticity of hair. However, studies by the inventors of the present application have revealed that alkyl glucosides also have a moisturizing effect while having the effect of improving the elasticity of hair.
Therefore, the intermediate treatment agent of the third invention exhibits, in addition to the above-described moisturizing effect on hair, a more excellent damage preventing effect and elasticity improving effect on the hair after the first agent treatment.

In addition to the basic action and effect of oxidative regeneration of cystine bond of hair protein by the second agent containing an oxidant, the following special action and effect are exhibited.

That is, the permanent waving agent of the fourth aspect of the invention contains an intermediate treatment agent containing an anionic polymer compound and / or an anionic surfactant, so that the effect of the first aspect of the invention is ensured in the permanent waving treatment. be able to. Then, after the anionized polymer compound and / or anionic surfactant of the intermediate treatment agent have been sufficiently adsorbed on the hair, the cationized polymer compound and / or cationic surfactant of the second agent are Since the complex is formed, the elasticity of the hair is further improved. Further, in forming the anionic-cationic complex, since the cationic component is used as the second agent, the feel of the finished hair (finger feeling) is particularly good.
