DETAILED DESCRIPTION OF THE INVENTION

[0001]

FIELD OF THE INVENTION The present invention relates to detergent compositions.

[0002]

2. Description of the Related Art A softening agent is added to a cleaning agent in order to prevent the textile product after washing from losing its softness due to dropping of a fiber treatment agent or adhesion of salts, etc., and to give a rough feel. That has been considered. Deposited on the fiber surface,
As a softening agent that gives flexibility to the texture of textile products,
Conventionally, clay minerals such as dialkyl-type quaternary ammonium salts and smectite have been used.
