摘要
建立了同时测定化妆品中2-氯-4-甲氧基苯酚、4-溴-2-甲氧基苯酚和三氯生3种防腐剂含量的气相色谱-质谱法。采用Agilent 6890N-5975气相色谱-质谱联用仪,配DB-5MS色谱柱（30 m×0.25 mm×0.25μm）,对3种型式的化妆品：口红（膏状）、香波（乳状）和化妆水（水状）的样品进行测试。结果表明,检测的相对标准偏差为0.86%~4.49%,平均回收率为92.2%~98.9%,对2-氯-4-甲氧基苯酚、4-溴-2-甲氧基苯酚和三氯生的检出限分别为0.1,0.5及0.1 mg/L。
Method for simultaneous determination of content of three preservatives,2-chloro-4-methoxyphenol,4-bromo-2-methoxyphenol and triclosan in cosmetics by gas chromatography-mass spectrometry（GC-MS） was established.Agilent 6890N-5975 GC-MS with DB-5MS GC column（30 m×0.25 mm×0.25 μm） was adopted as the main instrument.Samples of three forms of cosmetics,lipstick（as gel form）,hair shampoo（as emulsion form） and toilet water（as aqueous solution form） were taken for testing.The results showed that the relative standard deviations lies between 0.86% and 4.49%;the recoveries achieves between 92.2% and 98.9%;while the limit of detection for 2-chloro-4-methoxyphenol,4-bromo-2-methoxyphenol and triclosan was identified as 0.1,0.5 and 0.1 mg/L respectively.
