Abstract
The thin-layer chromatography technique using the plate with coated silica including of 5% calcium sulphate and the solvent system consisting of methylethylketone-benzen-ethanol-water was successfully applied to the general analysis of both commercial liquid shampoo and liquid dish washing detergents in the previous report.
Subsequently, the authors tested about the cationic surface active agents contained in commercial and prepared hair rinses or hair conditioners by the entirely same experimental conditions, and cationic surfactants were separated and identified from the mixture of emulsifiers, fatty acid alkylolamides, higher fatty alcohols, and lanolin. It was also possible to separate the above additive components by the selection of suitable indicating reagents.
