Abstract

Surface active alkylglucosides are prepared in a 2-step process from starch or starch degradation products such as polyglucose or glucose syrup, the first step consisting of reaction with a short chained alcohol, particularly butanol, while the second step comprises transacetalization with the longer chained C.sub.8-22, more particularly C.sub.12-18, alcohol, with fatty alcohols of natural origin preferably being used.
