Abstract: A method was established to determine residual content of phthalic acid esters (PAEs) in cosmetics.Samples were dissolved and then extracted under assistance of ultrasonic wave.Detection was performed using multiple reaction monitoring mode.The quantification was obtained utilizing the external standard method.Recoveries of residual content PAEs,with spike of ten times of the detection limit were 76.2%-95.2%,and the RSDs of the method were 4.4%-8.9%.The method can be applied to determine ten kinds of PAE in cosmetics simultaneously.

Key words: cosmetics, liquid chromatography-mass spectrometry (LC-MS), phthalic acid esters
