A process for making alkoxylated glucose derivatives comprising lipophilic substituents in the form of hydrocarbon or substituted hydrocarbon moieties with from 8 to 30 carbon atoms, wherein at least 5 wt.% of the glucose derivatives have three moles of said lipophilic substituents per mole of glucose, said process comprising: (i) contacting a glucose derivative with a lipophilic reagent comprising a hydrocarbon or substituted hydrocarbon moiety with from 8 to 30 carbon atoms under reaction conditions effective to form a lipophilic glucose intermediate comprising the lipophilic substituents wherein at least 75 wt.% of the glucose derivative have two moles of said lipophilic substituents per mole of glucose; and (ii) contacting the lipophilic glucose intermediate with an alkylene oxide at reaction conditions effective to form an alkoxylated, lipophilic glucose intermediate substituted with the alkylene oxide, and (iii) contacting the alkoxylated, lipophilic glucose intermediate with th lipophilic reagent under reaction conditions effective to form the alkoxylated glucose derivative comprising lipophilic substituents wherein at least 5 wt% of the glucose derivative have three moles of said lipophilic substituents per mole of glucose.
