DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hair cleaning composition having low skin irritation, good foaming, excellent foam creaminess, and excellent conditioning effect after washing.

[0002]

2. Description of the Related Art Hitherto, a hair cleaning composition which has excellent foaming and foam creaminess and a good conditioning effect after washing has been studied. For example,
In order to improve the feeling of rinsing during hair washing, it has been attempted to blend a cationic polymer such as cationic cellulose with a normal (single-chain, one-polar group-containing) anionic surfactant which is a main ingredient of a hair washing agent, It has been found that this formulation improves the rinsing feel. This is because an anionic surfactant for hair washing such as polyoxyethylene lauryl ether sulfate or alkyl sulfate forms a complex salt with a cationic polymer at the time of rinsing and is adsorbed on the hair. On the other hand, the blending of the cationic polymer has disadvantages such as hardening of the hair at the time of rinsing or finishing. Therefore, recently, a hair cleansing agent containing an amphoteric surfactant and a specific amphoteric polymer has been studied. When this is used, the conditioning effect after washing is good, but the foaming and the creaminess of the foam are not sufficiently satisfied. In order to solve these problems, a combination of an amphoteric surfactant, a quaternary ammonium, a carboxyl group-containing anionic surfactant (Japanese Patent Laid-Open No. 62-288694), a nonionic surfactant, a quaternary ammonium And combinations of carboxyl group-containing anionic surfactants (JP-A-63-317596 and JP-A-8-325595). However, these cleaning agents all foamed, and were not satisfactory in terms of foam creaminess. In addition, skin irritation was not sufficient. As described above, a hair cleaning composition having low skin irritation, good foaming, excellent foam creaminess, and a good conditioning effect after washing has not yet been developed. Was rare.

[0003]

The present inventor has made intensive studies to improve such disadvantages of the prior art, and as a result,
It has been found that the above-mentioned drawbacks can be remarkably improved by mixing a specific two-chain dipolar group-containing anionic surfactant with a cationic polymer, and the present invention has been completed. That is,
An object of the present invention is to provide a hair cleaning composition having low skin irritation, good foaming, excellent foam creaminess, and a good conditioning effect after washing.
