Abstract:

Liquid chromatography-tandem mass spectrometric (HPLC-MS/MS) method was established for the simultaneous determination of 15 prohibited drugs in hair cosmetics. Samples were extracted by methanol ultrasonic, separated by a C18 column, and determined by multiple reaction monitoring (MRM) scanning mode. The limits of detection (LODs) of the 15 prohibited drugs in various kinds of cosmetics are in the range of 1-20 μg/kg, with a linear relationship in the range of 10-200 μg/L, and the correlation coefficients are all greater than 0.998. The average recoveries are in the range of 84.2%-114.6%, and the relative standard deviation (RSD, n=6) is in the range of 1.7% to 9.7%. The method is simple, sensitive and accurate, and is suitable for the quick screening of 15 prohibited drugs in hair cosmetics.

Key words: HPLC-MS/MS, cosmetics, prohibited drugs
