Abstract:

An analytical method for the determination of bromisoval, carbromal and carisoprodol in cosmetics was developed based on high-performance liquid chromatography (HPLC). This method was capable of simultaneously quantifying the three analytes in a single run by combining a diode array detector (DAD) and an evaporative light scattering detector (ELSD) in series. The limits of quantitation (LOQs) for bromisoval and carbromal were 5 mg/kg, and the average recoveries ranged from 90.7% to 100.5% with the relative standard deviations (RSDs) less than 5.8%. The LOQ for carisoprodol was 20 mg/kg, and the average recoveries ranged from 96.8% to 103.9% with the RSDs less than 5.9%. The suspicious samples were subjected to further verification with high-performance liquid chromatography tandem mass spectrometry (HPLC-MS/MS). This method is simple, fast and suitable for the routine analysis of bromisoval, carbromal and carisoprodol in cosmetics.

Key words: cosmetics, bromisoval, carbromal, carisoprodol, high-performance liquid chromatography, mass spectrometric verification
