Abstract:

A method based on liquid chromatography tandem mass spectrometry (LC-MS/MS) was established for the determination of 16 kinds of anti-infective drugs in cosmetics. The linear range of ketoconazole is 0.50-25 μg/g, and the linear range of the other 15 components is between 0.10-5.0 μg/g. The correlation coefficients are all greater than 0.99, and the RSD of precision test is less than 1.8%. The detection mass concentration of ketoconazole is 25 ng/mL, and the detection mass concentrations of the other 15 components are less than 10 ng/mL. The recoveries are in the range of 86.0%-112.4%. The method has good linearity, precision and recovery. It is suitable for the detection of 16 kinds of anti-infective drugs in cosmetics. Combined with the national standard method, this method adds the detection of 8 components, strengthens the supervision of cosmetics and reduces the safety risk of cosmetics.

Key words: LC-MS/MS, cosmetic, anti-infective drugs
