Abstract:

A method of high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS)was developed for simultaneous determination of 22 prohibited substances in hair growth cosmetics. After dispersed in saturated sodium chloride solution, the samples were ultrasonically extracted with acetonitrile, and separated by gradient elution. The analysis was performed under multiple reaction monitoring (MRM). Matrix-matched standard curve was used for quantitative analysis. The results show that the 22 prohibited substances show good linear relationship within the range of corresponding mass concentrations with the correlation coefficients (r) more than 0.995. The limits of detection (LODs) are 4.9-49.7 ng/g. The average recoveries are within the range of 80.7%-110.3% with the RSD (n=6) less than 15% in the two matrices. With the advantages of simplicity, sensitivity and accuracy, the established method is suitable for the analysis of the 22 prohibited substances in hair growth cosmetics.

Key words: HPLC-MS/MS, hair growth cosmetics, prohibited drug
