摘要： The present invention relates to a method for preparing a cationic surfactant in which physical chemical characteristics such as softness, antistatic properties, etc. as well as biodegradability are quite excellent due to having an ester group and a hydrophilic hydroxyl group in its molecules. A cationic surfactant of the present invention is prepared by reacting tertiary amine drivatives, fatty acid, and epihalohydrin, and prepared simply by reacting esterification and quaternary reactions in one step with a high yield. The above cationic surfactant is a high grade alkyl quaternary ammonium compound as represented in General Formula (1), wherein R1 is a C1-C4 alkyl group; R2 is a C7-C21 linear or branched alkyl or alkenyl group; A is OCOR3, NHCOR3 or OH; R3 is a C7-C21 linear or branched alkyl or alkenyl group; X is a halogen atom; and n is an integral number from 2 to 6.
