A four-neck flask provided with a stirrer, a thermometer and a dehydrating tube was charged with 200 g of the N-(2-hydroxyethyl)-N-methyloctadecylamine and 174 g of octadecanoic acid. The mixture was heated to 180° C. and maintained at this temperature for 12 hours while distilling off the water thus formed. Thus 350 g of N-(2-octadecanoyloxyethyl)-N-methyloctadecylamine was obtained. Based on the NMR and IR spectra, it was confirmed that this product had the following structure. This compound will be referred to as the enhancer 25 hereinafter. ##STR31##
