Reaction Steps

A four-necked flask equipped with a tube for supplying nitrogen gas, a stirrer, a cooler, a thermostat, and a dropwise funnel was charged with 100.16 parts by weight of lauric acid and 0.0622 part by weight of phosphoric acid (a purity of 85%) followed by heating to 140° C. Subsequently, 222.24 parts by weight (molar ratio of glycidol/lauric acid=6) of glycidol was added drowpwise over 5 hours to allow to react until oxirane oxygen concentration in the reactant attains below 0.1% while maintaining the reaction temperature at 140° C. for 26 hours, to obtain approximately 300 parts by weight of a fatty acid esters composition of a polyglycerine (a hexaglycerine monolaurate composition). Content of the monoester was 87.7% based on the HPLC analytical condition No. 1 as described hereinabove.
