Abstract:

A simultaneous determination method was developed for the reliable screening, quantification and confirmation of 24 allergens in cosmetics by gas chromatography triple quadrupole mass spectrometry (GC-MS/MS) . The samples were ultrasonic extracted from cosmetics with methanol, and then qualitative and quantitative analysis was performed by GC-MS/MS under multi reaction monitor mode (MRM) . The results show that the 24 allergens have a good linear relationship in the range of 0.1-10.0 mg/L with correlative coefficients (r 2) larger than 0.993, and the average recoveries range from 81.8% to 106.7% at three spiked levels with relative standard deviations of 1.3%-8.7%. The detection limit is 1-3 mg/kg and the quantification limit is 10 mg/kg.

Key words: gas chromatography triple quadrupole mass spectrometry, cosmetics, allergen
