WebFeb 1, 2024 · The polar moieties of these oligomers (M w <1000Da) were supplied by glycerol and glycerol carbonate rather than ethylene oxide as in most commercial surfactants. The insertion of linear carbonate groups into the glycerol-based skeleton rendered the oligomers amphiphilic, resulting in a decrease in air/water surface tension … The handling of this chemical may incur notable safety precautions.
