Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cleaning compositions. More specifically, the present invention relates to a detergent composition that has good detergency and imparts excellent flexibility and antistatic properties to textile products after washing.

In a cleaning composition for textile products, it is desired that the textile product after washing has excellent flexibility and antistatic properties as well as good detergency. For this reason, many attempts have been made since ancient times, but none of them have improved cleaning power or
It has been difficult to achieve both flexibility and antistatic properties.

The present inventors have conducted repeated research under such circumstances and have arrived at the present invention. That is, the present invention provides diethylenetriamine-
