Abstract:

A method for simultaneous determination of 94 kinds of illegally added compounds in cosmetics by ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was established. The cosmetic samples were extracted with the mixed solvent of 70% acetonitrile-water under ultrasonic assistance. Then the components in the purified extract were separated by CORTECS?UPLC?C18 column (2.1 mm×100 mm, 1.6 μm) with 0.1% formic acid/acetonitrile solution-0.1% formic acid and 5 mmol/L ammonium acetate as mobile phase, and then detected by UPLC-MS/MS. The method showed that good linearity was obtained with correlation coefficients higher than 0.995. The range of the limit of quantitation for this method was 0.025-0.1 μg/g. The spiked recovery was in the range of 51.1%-129.3%, and the RSD was 1.8%-19.0%.

Key words: cosmetics, illegally added compound, ultra performance liquid chromatography-tandem mass spectrometry
