DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning composition for hair and the like, and more particularly, to a hair cleaning composition which is excellent in smoothness and softness when rinsing, and good finger passing after rinsing. Composition.

[0002]

2. Description of the Related Art
In cleaning compositions such as shampoos and rinse-in shampoos that combine cleaning and finishing performance, it is possible to add a cationic polymer substance such as cationized cellulose to prevent friction of hair during rinsing and prevent squeaking of hair. It is known that this effect is manifested when the cationic polymer substance interacts with the surfactant incorporated in the composition to form a precipitate, and the precipitate is adsorbed on the hair. Have been.

[0003] However, although the method of blending the cationic polymer substance can prevent squeaking of the hair, the smoothness and softness at the time of rinsing, which is the actual feeling of use that a consumer demands for a detergent composition. In addition to this, there is a drawback that not only is the point is not sufficient, but also there is a sense of resistance in finger passage after rinsing, which is not good.

Therefore, as an attempt to improve the moist feeling and the usability after drying, a hair cosmetic or cleaning composition containing a linear polysiloxane-polyoxyalkylene copolymer (Japanese Patent Application Laid-Open No. Hei 4-212605). JP-A-6-4
No. 9486) have been proposed, but none of them have sufficient effects to improve the feel of the hair, and therefore, a hair cleaning composition which overcomes these problems and gives the hair a good feel. Is desired.

[0005] The present invention has been made in view of the above circumstances,
You can get smoothness and softness when rinsing,
Moreover, it is an object of the present invention to provide a hair cleansing composition that is excellent in finger passing after rinsing.
