To prepare a O/W type nonionic durable softner(ANSA), synthesized 1, 3-dihexadanoyl-2, 7-dioxy-6, 8-di(2-hexadecanoyloxyethyl)-1, 3, 6, 8-tetraazacyclodecane as the main component of softner, was blended with beef tallow, anhydrous lanolin, polyoxyethylene(20) oleyl ether, sorbitan sesquioleate, and polyoxyethylene(7) stearyl ether in various compositions. Emulsion stability of ANSA was good, and the mixed HLB value was 9.8. After the treatment of ANSA to all cotton fabrics, the physical properties such as tear strength, crease recovery, and flexing abrasion resistance were measured, respectively. As a result of the measurement, ANSA was proved to be durable softner with good softness.
