Notes:
Gas chromatography with electron impact ionization is shown to be an excellent tool for the analysis of complex mixtures of ethoxylated fatty alcohols non-ionic surfactants with a low degree of polymerization. Ethoxylated fatty alcohols with odd and even numbers of carbon atoms, straight and branched-chain, present in commercial raw materials were detected and identified by their fragmentation modes and their retention times. Comparative analysis of the more diagnostic mass spectrometric data (ions relative to the entire hydrocarbon chain and to the ethoxylate moiety) can be useful for easy and unambiguous characterization of the structures of these compounds.
