Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention has an excellent conditioning effect on hair while satisfying essential conditions as a detergent such as foamability and detergency, and is excellent in foam quality and usability. The present invention relates to a detergent composition.

[0002]

2. Description of the Related Art With the recent increase in consumers' awareness of hair care, the demand for hair care products has been diversified.
In the case of detergents such as shampoos, in addition to the basic functions of detergents such as detergency and foaming properties, they also have good foam quality and finger-handling properties during washing and rinsing, and usability such as hair does not get dry. It is an important factor that the goodness of the hair and the goodness of the finished hair such as easiness of cohesion of the hair after drying, suppleness, and good combability are satisfied.

Conventionally, cationic polymers such as cationized cellulose and siloxane compounds have been widely used as conditioning agents for shampoos. However, when a shampoo containing a cationic polymer alone is continuously used, the cationic polymer accumulates on the hair, and there are drawbacks such as sticky feeling and stiff feeling. Although the shampoo containing the siloxane compound has an excellent finished feel, it is sufficiently satisfactory in terms of usability such as foaming is significantly reduced due to its original defoaming property and finger passage during washing is deteriorated. Was not. On the other hand, for the purpose of improving foaming, many attempts have been generally made to add fatty acid ethanolamides such as lauric acid monoethanolamide and lauric acid diethanolamide, but the defoaming property of the siloxane compound is covered. In order to do so, it is necessary to mix in a large amount, in this case,
Fatty acid ethanolamides are adsorbed on the hair, and there are drawbacks such as an unpleasant peculiar squeaky feeling during rinsing.

SUMMARY OF THE INVENTION With the background of the above-mentioned prior art as an object, the object of the present invention is to satisfy the essential conditions as a cleaning agent such as foaming property and detergency, while maintaining the foam quality and finger properties during washing and rinsing. It is an object of the present invention to provide a detergent composition which has good usability such that the hair passes easily and does not cause the hair to get dry, easiness of cohesion of hair after drying, suppleness, good combability, and the like.
