A new method, using poly‐ O ‐acetyl‐β‐ d ‐glycopyranosylbromide, methyl 9‐or methyl 12‐hydroxyoctadecanoate and triethylamine as catalyst, is described for the synthesis of a new class of nonionic surfactants. Chemical structures were identified using 1 H and 13 C nuclear magnetic resonance spectroscopy including two‐dimensional techniques and Fourier transforming infrared. Critical micelle concentrations and surface tension profiles of these O ‐alkyl‐β‐ d ‐glycosides in water were determined.
