Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a permanent wave composition capable of imparting a continuous conditioning effect to hair and preventing damage during the process of permanent wave or straightening treatment.

[0002]

2. Description of the Related Art The surface of hair is gradually roughened by a permanent wave or curly straightening treatment, and the texture and gloss of the hair deteriorate. This not only impairs the beauty of the hair, but also makes the hair more easily damaged during daily shampooing and blowing.

For this reason, various methods have been attempted for the purpose of continuously providing a conditioning effect and keeping the hair beautiful in the process of treatment such as permanent wave. For example, a permanent wave second agent in which a specific cationic polymer and an anionic or amphoteric activator are blended (JP-A-56-92810, JP-A-57-31605, JP-A-57-212111,
Japanese Patent Application Laid-Open No. 61-183214), a cationic polymer is applied in a reducing process in order to further improve durability, and an anionic activator or an amphoteric activator is applied in an oxidizing process (Japanese Patent Application Laid-Open No. 56-100712, Japanese Patent Publication No. Kaisho 56-150009
JP-A-58-150506), those to which a specific silicone polymer has been added (JP-A-63-313717,
JP-A-1-110611, JP-A-2-255608
No.), a combination of an amphoteric polymer and a cationic polymer or an anionic polymer (JP-A-56-92812).
No. 1, JP-A-1-188547, JP-A-3-86810
No.) etc. have been proposed.

However, in the case where the silicone polymer is simply added, the silicone polymer is more likely to be adsorbed on the healthy part than on the more damaged part of the hair. There is a problem that it becomes sticky. Further, in the case of blending various polymers, sufficient sustainability was not obtained. Among these, when a cationic polymer and an amphoteric polymer are combined, relatively long-lasting property is obtained, but in general, an excessive amount of the polymer is adsorbed to the hair in these combinations, so that the tip and the damaged part are especially stiff. There is a drawback in that the hair is caught and the whole hair feels a sense of volume, so that it is not suitable for suppleness, especially in the case of oriental human hair.

[0005]

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a composition for permanent wave which gives a continuous conditioning effect to hair, and is free from stiffening or snagging and giving a supple finish. It is in.

[0006]

Under such circumstances, as a result of intensive studies, the present inventors have found that by blending a specific copolymer in each of the first and second agents for permanent wave, The present invention has been completed based on the finding that it does not cause stiffening or snagging due to excessive adsorption of a polymer on a tip or a damaged portion, imparts continuous gloss and smoothness to hair, and provides a smooth and supple finish, and completes the present invention.
