PROBLEM TO BE SOLVED: To provide a high productivity process of an ethoxylate. SOLUTION: Provided is a production process of an ethoxylate, which comprises a step of charging a portion of the product from previous production (a "heel") or an ethoxylate to a reactor, optionally, a step for charging from about 0.2 wt.% to an amount equal or greater than the amount of heel of a 1-56C non-phenolic alcohol to a reactor, a step of charging ethylene oxide to activate a double metal cyanide ("DMC") catalyst, a step of adding a 1-56C non-phenolic alcohol simultaneously with ethylene oxide for a portion of the process and a step of continuing addition of ethylene oxide following completion of the simultaneous 1-56C non-phenolic alcohol and ethylene oxide addition, is provided.
