Zusammenfassung:	A process for reducing volatile, odor-causing impurities in alkoxylated alcohols comprising adjusting the pH of an alkoxylated alcohol product mixture containing such impurities to a range of from about 7 to about 8.5 to produce an alkaline alkoxylated alcohol mixture and steam stripping the alkaline alkoxylated alcohol mixture at an elevated temperature for a period of time sufficient to produce a steam stripped alkoxylated alcohol containing a reduced amount of odor-causing impurities.
