A process for the production of alkoxylated alkyl and/or alkenyl polyglycosides including reacting alkylene oxides with alkyl and alkenyl polyglycosides corresponding to formula (I): R.sup.1O-[G].sub.p wherein R.sup.1 is an alkyl and/or alkenyl group containing 4-22 carbon atoms, G is a sugar unit containing 5 or 6 carbon atoms and p is a number of 1-10, wherein the alkyl and/or alkenyl polyglycosides corresponding to formula (I) are in the form of a water-containing preparation with a water content of more than 5% by weight, based on the weight of the water-containing preparation is provided. The alkoxylated alkyl and/or alkenyl polyglycosides may be incorporated into agrochemical formulations, herbicides, laundry and dishwashing detergents, cleaning preparations, and pharmaceutical and cosmetic formulations.
