Abstract:

An ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed and validated for the simultaneous determination of twelve whitening ingredients in cosmetics. The sample preparation, liquid chromatography and mass spectrometric conditions were optimized. The optimized conditions were as follows: the samples were ultrasonically extracted with 50% methanol aqueous solution containing 0.025% formic acid, and filtered by polytetrafluoroethylene (PTFE) membrane. Adequate chromatographic retention was achieved on a Waters BEH C18 column under gradient elution with acetonitrile and 0.01% formic acid aqueous solution. A triple-quadrupole mass spectrometer equipped with an electrospray source was set up in the both positive and negative ion mode for multiple reaction monitoring (MRM). The results show that among the three cosmetics with different types of matrices, the linearity of the twelve whitening agents is good in the concentration ranges, with the correlation coefficient (R) greater than 0.995. The limits of detection (LOD) and limits of quantitation (LOQ) are 0.06-15.00 mg/kg and 0.20-50.00 mg/kg, respectively. Spike recovery is performed on three cosmetics at three different spike levels, and the average recoveries in different types of cosmetics are in the range of 78.6%-111.8% with the relative standard deviation of 1.0%-6.2%(n=6). The validated method is successfully applied to the determination of 12 components in 18 batches of cosmetics. The results indicate that the quantitative method is simple and accurate. It is suitable for quantitative determination and qualitative confirmation of the 12 whitening agents in different matrices of cosmetics.
