Abstract:

Environmental hormone is a kind of substance that can disturb biological endocrine, among which bisphenols and alkylphenols have great potential harm because they are widely used in the manufacture of plastics. At present, there are many researches on the related detection technologies in the fields of environment and food, but there are few reports on high-throughput simultaneous detection of bisphenols and alkylphenols in cosmetics. In order to analyze the migration amount of bisphenols and alkylphenols environmental hormones in cosmetics, an ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) method was developed for the determination of 13 environmental hormones including 9 bisphenols and 4 alkylphenols in essential oil cosmetics. The chromatographic conditions, extraction reagent, dosage and ultrasonic time were optimized, then actual samples were measured with this established method. The essential oil cosmetics were extracted by ultrasonic extraction with 10% ammonium-acetonitrile solution, concentrated by nitrogen blowing, and eluted by gradient elution of methanol and water on an Agilent Poroshell EC-C18 column (3.0 mm×150 mm, 2.7 μm). The 13 analytes were scanned by electrospray ion source negative ion mode (ESI-), and analyzed with multiple response monitoring model (MRM). The results show that there is a good linear relationship for 13 kinds of bisphenols and alkylphenols environmental hormones in the certain mass concentration range of 0.25-200 ng/mL, with the linear correlation coefficients greater than 0.99. The limits of detection (LOD) and the limits of quantitation (LOQ) of each substance are 0.000 375-0.007 5 µg/g and 0.001 25-0.025 µg/g, respectively. The average recoveries at three spiked levels of 0.025, 0.05 and 0.25 µg/g range from 81.8% to 113.4% with the intra-day precision (n=6) of 1.1% to 8.5%, and the inter-day precision (n=18) of 3.5% to 11.5%. The method is established with simple pretreatment, good recovery and high stability, which has achieved effective chromatographic separation of 13 target substances. It is suitable for simultaneous quantitative and qualitative analysis of 13 bisphenols and alkylphenols environmental hormones in essential oil cosmetics.
