Abstract:

An analytical method of ultra performance liquid chromatography-triple quadrupole mass spectrometry (UPLC-MS/MS) was developed for the simultaneous determination of 15 prohibited substances (diphenhydramine, tripelennamine, chlorpheniramine, etc.) in cosmetics. The UPLC separation was carried out on a Waters Acquity UPLC? BEH C18 column (1.7 μm × 2.1 mm × 50 mm) by gradient elution using methanol and ammonium acetate-formic acid solution. The flow rate was 0.4 mL/min and the sample injection amount was 3 μL. The electrospray ionization source in positive ion mode (ESI +) was used for qualitative analysis and quantitative analysis of fifteen prohibited drugs in the multiple reaction monitoring (MRM) mode. The established method exhibited a good linear relationship in the corresponding concentration range. The linear correlation coefficient is 0.999 3-0.999 9; the recoveries of standard addition are between 87.21%-99.39% (n=3); the relative standard deviation is 2.28%-5.27% (n=6); the detection limit range is 0.014 3-0.239 2 mg/kg; the limit of quantification range is 0.004 3-0.797 2 mg/kg. The method is accurate and reliable, and is suitable for simultaneous determination of various prohibited substances in cosmetics.

Key words: prohibited substance, cosmetics, ultra performance liquid chromatography-triple quadrupole mass spectrometry
