Abstract:

Simultaneous determination of 17 sulfonamides in cosmetics by ultra high performance liquid chromatography tandem triple quadrupole mass spectrometry (UPLC-MS/MS) was established. The samples were dissolved in 50% methanol aqueous solutions by ultrasonic extraction, and the Waters ACQUITY UPLC® BEH C18 column (100 mm×2.1 mm, 1.7 μm) was used. The mixture of methanol and 0.1% (volume fraction) formic acid aqueous solutions with different volume fraction was used as the mobile phase for gradient elution, measured with liquid chromatography tandem mass spectrometry in electrospray ion mode and positive ion multiple reaction monitoring (ESI+), and quantification by external standard method. The results show that the matrix effects of the sample are small and can be ignored. There is a good linear relationship for 17 sulfonamides at the mass concentrations of 0.5-100 ng/mL, and the correlation coefficients are greater than 0.999. The detection limits are 0.002-0.028 μg/g, and the quantitation limits are 0.006-0.094 μg/g. The average recovery is 97.5%-118.3% with the standard references added at the content of 0.25-2.5 μg/g in blank samples, and the relative standard deviations (n=6) are 0.74%-6.37%. According to this method, 10 batches of anti-acne cosmetics are analyzed, and none is detected with 17 sulfonamides.
