Description

Detailed Description of the Invention

[0001]

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

2. Description of the Related Art In a two-bath type permanent wave, a cystine bond (disulfide bond) of a hair protein is basically produced by a first agent containing at least a reducing agent.
Is subjected to reduction cutting, and then winding using an instrument is performed, and then the cystine bond of the hair protein is oxidatively regenerated by a second agent containing at least an oxidizing agent. However, in the above-mentioned treatment of the first and second agents, the hair is considerably damaged by the severe treatment of oxidation and reduction,
For example, there have been problems such as deterioration of elasticity and strength of hair and deterioration of touch.

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, as a compounding ingredient for the first agent, the second agent or the intermediate treatment agent, various polymer compounds and surfactants effective for improving the elasticity of hair have been proposed.

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,
By forming a complex with the anionic surfactant as the second agent, the effect of improving the feel of the hair (feeling of finger passage) can be expected.

The permanent wave intermediate treatment agent disclosed in JP-A-7-89829 contains triglyceride and a surfactant. Generally, a surfactant can be expected to have the effect of improving the wettability of water on the hydrophobic surface of hair and promoting the penetration of various components into the hair.

[0006]

However, the above-mentioned Japanese Unexamined Patent Application Publication No.
In the permanent composition according to JP 6-100710 A, the cationic polymer is blended in the first agent and applied to the hair which is not yet sufficiently swollen, so that it is not always sufficient for the hair. May not be adsorbed. Therefore, the complex formation with the anionic surfactant may also be insufficient.

When a surfactant is contained as in the permanent wave intermediate treatment agent disclosed in JP-A-7-89829, the above-mentioned general effects can be expected. Alkyl glucosides that can be expected to have a moisturizing effect are also disclosed in the surfactants. However, surfactants are generally considered not to contribute to improving the elasticity of hair.

Therefore, the present invention shows an excellent effect of preventing damage and elasticity of the hair after the treatment with the first agent, and further an intermediate treatment which can enhance the moisturizing effect of the hair while maintaining the elasticity. An agent, a permanent wave agent constituted by including the intermediate treatment agent and capable of expecting a synergistic addition effect of an anionic surfactant, and a permanent wave treatment method using the permanent wave agent are provided. It is a task to be done.

Therefore, the intermediate treatment agent of the second invention not only exhibits an excellent damage prevention effect and elasticity improving effect on the hair after the first agent treatment, but also has a moisturizing effect on the hair without inhibiting these effects. Can also be increased. That is, it is possible to achieve both the soft and tight feel of the hair and the excellent elasticity of the wave.

(Operation and Effect of the Third Invention) The permanent wave agent of the third invention contains an intermediate treatment agent containing a cationized polymer compound and / or an amphoteric polymer compound. In processing,
The effect of the first invention can be secured.

A second layer containing an anionic surfactant
Since it contains an agent, it forms a complex with the anionic surfactant of the second agent after the cationized polymer compound or the like of the intermediate treatment agent is adsorbed on the hair, and further improves the elasticity of the hair.
It can be expected to have the effect of improving the feel of the hair (feeling of finger passage).
