Abstract:

A method was established for the determination of 18 organophosphate esters in cosmetics by dispersive solid-phase extraction coupled with gas chromatography-tandem mass spectrometry (GC-MS/MS). The samples were extracted with acetonitrile and purified with an HMR-Lipid sorbent, separated on an HP-5MS UI chromatographic column (30.0 m× 0.25 mm, 0.25 μm), monitored in dynamic multiple reaction monitoring (dMRM) mode, and quantified by the internal standard method. The results show good linearity for all 18 organophosphate esters, with correlation coefficients (R2) greater than 0.99. The limits of detection range from 0.001 to 0.050 mg/kg, and the limits of quantitation are 0.003-0.100 mg/kg. The average recoveries at low, medium and high spiking levels are between 85.8% and 110.6%, with relative standard deviations less than 9.9%. The method features simple sample preparation, rapid and efficient analysis, and accurate quantification, making it suitable for the qualitative and quantitative determination of 18 organophosphate esters in cosmetics.

Key words: HMR-Lipid sorbent, gas chromatography-tandem mass spectrometry, cosmetics, organophosphate esters
