Capillary supercritical fluid chromatographic methods were developed for the separation and quantitation of oligomers of propoxylated glycerols and fatty acid‐esterified propoxylated glycerols. Samples containing mole ratios (propylene oxide to glycerol) of 5, 8 and 14 were chromatographed. Separations depended primarily upon the molecular weight or the number of the propylene oxide units. The oligomer distributions in the propoxylated glycerol and the oleic acid‐esterified propoxylated glycerol samples were determined.
