Kind Code:
B2
Abstract:
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.
