Detailed Description of the Invention

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a detergent composition, particularly a hair detergent composition which is excellent in foaming power, can impart an appropriate slip during washing, and can impart a preferable feel after rinsing. Regarding

[0002]

2. Description of the Related Art Conventionally, the problems to be solved by the invention
The water-soluble polymer contained in the detergent composition for washing hair and body is a cationized cellulose (Japanese Patent Publication No. 45-20).
318), a cationic derivative of a polysaccharide,
Alternatively, a copolymer containing a monocation-containing (meth) acrylate (JP-A-46-750), a dialkyldiallylammonium chloride-based polymer (JP-A-63-
122263), or a polymer containing an amphoteric functional group (JP-A-58-124712) and the like (here, a monocation-containing (meth) acrylate means 1 unit of cation per 1 molecule of monomer). Refers to an acrylate or a methacrylate having a group). These polymers give a favorable feel during washing,
It can be said that it has a sufficient function in the conditioning feeling for loosening the entanglement of hair. However, with the recent spread of hair coloring and bleaching, shampoos are required to have a function of repairing hair damage more than ever before.
That is, in a shampoo containing a texture-improving agent such as a non-volatile silicone or an oil agent, a shampoo capable of remaining a necessary amount of the texture-improving agent on the hair without impairing the basic functions such as foaming and conditioning feeling during overwashing is required. ing. From this point of view, conventional polymers have insufficient functions. Reasons for this include, for example, insufficient foaming power at the time of washing and the inability to leave an effective amount of the feel-improving agent on the hair. In addition, a conditioning shampoo composition containing a polymer having a relatively high cation charge density (Japanese Patent Publication No. 11-507076).
In the case of Japanese Laid-Open Patent Publication No. 2003-242, although the purpose of leaving the feel-enhancing agent is achieved, the conditioning feeling is insufficient, and the uniformity of the adhesion of the feel-improving agent to the hair may be impaired, and therefore, the hair. It has the drawback that the luster of the can be lost.

The object of the present invention is to solve the problems of the above-mentioned conventional cationic polymers. Therefore, even in a system containing a feel-improving agent, foaming is rich when used,
It is an object of the present invention to provide a detergent composition which has a conditioning feeling for hair and can be easily combed even after drying, and which is particularly suitable for hair.
