Zusammenfassung:	To provide a fatty acid alkyl ester alkoxylate production method in which the amount of alcohol added can be increased within the range in which the detergency of the obtained fatty acid alkyl ester alkoxylate can be maintained while suppressing the decrease in catalytic activity.SOLUTION: Provided is a fatty acid alkyl ester alkoxylate production method, which is a fatty acid alkyl ester alkoxylate production method including an addition reaction step in which alkylene oxide is added to fatty acid alkyl ester in the presence of calcium sulfate catalyst and dihydric alcohol, and in which the contained amount of the dihydric alcohol is 1.4 mass% or more and 3 mass% or less of the total amount of substances in the system in the addition reaction step.SELECTED DRAWING: None 【課題】触媒活性の低下を抑制しつつ、得られる脂肪酸アルキルエステルアルコキシレートの洗浄力を維持できる範囲でアルコール添加量を増加させることができる脂肪酸アルキルエステルアルコキシレートの製造方法を提供する。【解決手段】硫酸カルシウム触媒と２価アルコールの存在下で、脂肪酸アルキルエステルにアルキレンオキシドを付加する付加反応工程を有する脂肪酸アルキルエステルアルコキシレートの製造方法であって、前記２価アルコールの含有量が前記付加反応工程における系中の物質全量の１．４質量％以上３質量％以下である、脂肪酸アルキルエステルアルコキシレートの製造方法。【選択図】なし
