Simultaneous Determination of 15 Coumarins and 10 Benzophenones in Sunscreen Cosmetics by QuEChERS/Ultra-high Performance Liquid Chromatography-Tandem Mass Spectrometry
A QuEChERS/ultra-high performance liquid chromatography-tandem mass spectrometric(UPLC-MS/MS) method was established for the simultaneous determination of 15 coumarins and 10 benzophenones in sunscreen cosmetics.The samples including cream,foundation,isolation and spray were extracted with acetonitrile,and purified with a combined adsorbent of 50 mg C,18, and 150 mg anhydrous MgSO,4,.The chromatographic separation for the analytes was achieved on a Zorbax SB-C,18,(RRHD) column(2.1 mm × 150 mm,1.8 µm). Gradient elution was performed using 0.1% formic acid solution(containing 5 mmol/L ammonium acetate) and acetonitrile.Then the analytes were determined with electrospray ionization in positive ion mode under multiple reaction monitoring(MRM),and quantified by external standard method,while the analytes in foundation and spray samples were quantified by matrix-matched external standard method.The experimental results indicated that good linearities were observed for 25 kinds of analytes in the respective concentration ranges,with their correlation coefficients(,r,) larger than 0.995.The limits of detection(LODs) and limits of quantitation(LOQs) for cream and isolation samples were in the ranges of 0.005-0.450 μg/g and 0.010-0.750 μg/g,while the LODs and LOQs for foundation and spray samples were 0.005-0.500 μg/g and 0.010-1.000 μg/g,respectively.Mean recoveries for the analytes at three spiked levels ranged from 80.8% to 113%,with relative standard deviations(RSDs) of 0.20%-6.8%.Moreover,the analytes in the sample solutions were stable within 48 hours.The proposed method is simple,sensitive and accurate,and it could be applied to the simultaneous determination of coumarin and benzophenone compounds in cosmetics.
