The separation of ethoxylated laurylalcohol oligomers and sorbitane monoleate oligomers was investigated by reversed-phase high-performance liquid chromatography on octadecyl silica (ODS) and porous graphitized carbon columns (PGC) with the eluent of a mixture of acetonitrile-water. The selectivity of ODS column differs from PGC column, because ODS column can separate only according to hydrophobicity, while PGC column is suitable for the separation clue to the steric parameters and also the ethylene oxide units of the molecule.
