摘要： The invention concerns a method for preparing Laminaribiose comprising a step for glycoside binding between a donor and an acceptor of glycosyl. The invention is characterized in that the glycosyl donor is in pyranose form and corresponds to formula (II); the glycosyl acceptor is in furanose form and corresponds to formula (III); said binding step is performed in solution in an anhydrous organic solvent, at a temperature ranging between −80° C. and 40° C., for a time interval ranging between 1 minute and 8 hours, in the presence of a suitable promoter.

摘要： Compositions comprising alkoxylated lipophilic polyol compounds, e.g., ehtoxylated, esterified methyl glucosides, are disclosed wherein at least 5% of the polyol derivatives have about three moles of the lipophilic substituent per mole of polyol. Quite advantageously, the disclosed polyol derivatives can be dissolved into aqueous solutions to provide liquid thickeners suitable for thickening surfactant-containing compositions, e.g., shampoos, at cold processing temperatures.
