Abstract:

The study aims to establish an analytical method for determination of 27 illegally added sulfonamides in cosmetics by ultra-high performance liquid chromatography-tandem mass spectrometry. The samples were extracted by methanol,and separated on Thermo Hypersil GOLD column (100×2.1 mm,1.9 μm), 0.1%(V/V)acetic acid aqueous solution and 0.1%(V/V)acetic acid acetonitrile solution were used as mobile phases with gradient elution. The quantitative analysis of 27 sulfonamides were operated in the electrospray ionization positive/negative mode using multiple reaction monitoring (MRM). The correlation coefficients of linear calibration curves are greater than 0.99 in the corresponding mass concentration ranges of the 27 sulfonamides. The average recoveries of the 27 sulfonamides at three spiked levels range from 79.3% to 112.2% with the relative standard deviations of 1.4%-13.1%(n=6). The LODS (S/N≥3) and LOQS(S/N≥10) are 2.3-97.6 μg/kg and 7.7-322.0 μg/kg, respectively. The results show that this method is simple, rapid, sensitive and reliable. It is suitable for qualitative and quantitative screening analysis of the 27 sulfonamides in cosmetics simultaneously.
