Thin layer chromatography technique using sillica coated plate and the solvent system consisting of methylethylketone-benzene-ethanol-water was successfully applied to the analysis of both commercial liquid shampoos and liquid dish washing detergents with following results.
1) Essential constituents in those test-samples, namely, fatty acid alkylolamides, anionic and nonionic surfactants, urea, free fatty alcohols and amines were separated and identified.
2) Detecting of free triethanolamine or ammonium sulfate suggested the presence of anionic surfactants based on these amines or ammonium salts.
3) A suitable selection of indicating reagents made it possible to separate higher alcohol sulfate from its ether sulfate.
4) It was also demonstrated that this procedure is useful to detect various impurities in those test samples.
