<p>A method for producing a polyoxyethylene alkyl ether sulfate, which comprises: a sulfation step wherein an ethylene oxide addition product of an alkyl alcohol having 8-22 carbon atoms is reacted with an SO3-containing gas, thereby obtaining a sulfated product of the ethylene oxide addition product; and a neutralization step wherein the sulfated product is neutralized, thereby obtaining a sulfate. The ethylene oxide addition product contains from 0.01% by mass to 1% by mass (inclusive) of an alkali metal hydroxide relative to the total mass of the ethylene oxide addition product.</p> |
