## Abstract

A detergent composition excellent in an antimicrobial activity. Thus, a detergent composition of the present invention is characterized by including: an imidazolinium betaine-based amphoteric surfactant; and 0.5 to 10% by mass of PEG-1 lauryl glycol represented by the following formula (I): wherein, m and n each represent the number of moles of added ethylene oxide and the average of m+n is 1. Also, the detergent composition preferably includes an ingredient having a microstatic effect or microcidal effect selected from divalent glycols, hinokitiol, trichlorocarbanilide, and benzalkonium chloride.
