Analysis of amphoteric surfactants of the alkylaminopropylglycine type by gas chromatography.
A procedure was developed for gas chromatographic analysis of glycine-type amphoteric surfactants. The commercial samples contained N-alkylaminopropylglycines, N-alkylamines and N-alkylaminopropylamines. Some di- and triacids were also detected. The method proposed allows a good separation according to both the carbon number and the chemical function.
