Abstract
Alkyl polyglycoside products having improved color properties are produced by a process which involves reacting a reducing sugar with an alcohol to obtain an alkyl polyglycoside reaction product containing unreacted alcohol which is removed in a thin film evaporator wherein the alkyl polyglycoside product film is contacted by liquid water which cools the film and reduces the amount of color bodies in the product.
