A simple and rapid procedure is described for the isolation, silylation and wide‐bore capillary gas chromatographic quantitation of sodium lauroyl sarcosinate in personal care products. The sample is dissolved in acidified dimethylformamide to simultaneously acidify/extract the lauroyl sarcosine; an aliquot is then derivatized with bis trimethylsilyltrifluoroacetamide and quantitated by widebore capillary gas chromatography with flame ionization detection.
