Abstract: A process for the preparation of sulfated alkanol oxethylates or alkylphenol oxethylates is described. After completion of the reaction with SO3, 0.1 to 0.5% by weight, relative to the alkanol oxethylates or alkylphenol oxethylates employed, of at least one of the following compounds: water, ethanol, 1-propanol, 2-propanol or n-heptane are admixed to the reaction mixture and liquid and gas are subsequently separated at a temperature of 20 DEG to 60 DEG C. The liquid is then neutralized with aqueous alkali as customary and leads to ether sulfate/water mixtures with considerably reduced contents of 1,4-dioxane which can either be used without further aftertreatment or with a considerably reduced outlay in terms of aftertreatment as personal hygiene agents and for various other purposes.
