Zusammenfassung:	PROBLEM TO BE SOLVED: To provide the production method of an alkylether sulfate whose color is improved. SOLUTION: The production method of an alkylether sulfate whose color is improved comprises a step of adding ethylene oxide to a higher alcohol in the presence of an alkoxylation catalyst, a step of adjusting the temperature of the reactant to 30 deg.C to 45 deg.C by cooling it and/or keeping it at a fixed temperature, a step of filtrating the reactant of this temperature range to remove the catalyst and a step of sulfating the reactant.
