Abstract: A sensitive method for the simultaneous determination of 16 polycyclic aromatic hydrocarbons (PAHs) and 17 phthalic acid esters (PAEs) in cosmetics by gas chromatography-mass spectrometry (GC-MS) coupled with solid-phase extraction (SPE) was established.Samples were ultrasonically extracted with acetonitrile,purified using PSA/Slica Glass SPE column,separated using Agilent Select PAH chromatographic column and detected by GC-MS with selected ion monitoring (SIM).Results indicate that the linear relationship of 16 PAHs and 17 PAEs in the range of 0.5-200 μg/L is good,with correlation coefficient greater than 0.99.The limits of detection and quantification of the method for PAHs are in the range of 0.6-1.0 and 1.9-3.3 μg/kg,respectively,the average recoveries of negative samples at three spiked levels are between 86.4% and 112.2%.The limits of detection and quantification of the method for PAEs are in the range of 0.4-2.3 and 1.5-7.6 μg/kg,respectively,the average recoveries of negative samples at three spiked levels are between 82.2% and 114.1%,and the relative standard deviation (RSD,n=6) is less than 10%.

Key words: cosmetics, polycyclic aromatic hydrocarbons, phthalic acid esters, solid-phase extraction, gas chromatography-mass spectrometry
