ABSTRACT:
Fatty alcohols are separated from a solution containing alkyl polyglycosides (APGs) and alcohols, wherein the alcohols and the alkyl groups of the APGs contain 10-18 C atoms and wherein the mean degree of polymerization of the (APGs) is 1.05-1.4 by distilling said solution at 160.degree.-200.degree. C. under a pressure of 0.1-20 hPa in a thin layer evaporator having a Reynolds number of 30-18,000.
