Abstract A process for the production of alkyl glucosides In the process which is based on transacetalization with propylene glycol, a saccharide component (B) containing starch or partial starch degradation products is first added to a reaction medium (A) containing at least propylene glycol and an acidic catalyst and, optionally, higher (C8-18) fatty alcohol, which has been heated to 100 to 130°C, resulting initially in the formation of propylene glycol glucoside which is transacetalized with fatty alcohol. The molar ratio of fatty alcohol to propylene glycol is at most 1. Working up by methods known per se gives a product containing a high proportion of C8-18 alkyl monoglucoside which is color-stable in alkaline medium. Quantities of propylene glycol and fatty alcohol recovered by distillation can be recycled without further working up.
