摘要：

Preparation of alkoxylated alkyl and/or alkenyl polyglycosides (A) comprises reaction of alkylene oxides with alkyl- and alkenyl polyglycosides (I) (in aqueous preparation form with a water content of about 5 wt.%). - Preparation of alkoxylated alkyl and/or alkenyl polyglycosides comprises reaction of alkylene oxides with alkyl- and alkenyl polyglycosides of formula (R1O-(G)p) (in aqueous preparation form with a water content of about 5 wt.%). - R1 = 4-22C alkyl or 4-22C alkenyl; - G = 5-6C saccarides; and - p = 0-10.
