A gas chromatography coupled with tandem mass spectrometry (GC-MS/MS) method is developed to determine 18 representative polycyclic aromatic hydrocarbons (PAHs) in cosmetics, including Benzo[a]pyrene (BaP) and others. The method offers high sensitivity and selectivity under selected reaction monitoring (SRM) mode to satisfy the requirements of both quantitation and qualitation. The extraction solvent system used in this study is acetone/hexane 1:1 (v/v) and other purification procedure is unnecessary. The linearities of 18 PAHs are validated in different concentration in the range of 0.25-20 ng/mL individually with coefficient correlation (r) higher than 0.996. The recoveries for spiking 3 different concentrations are from 87.40% to 120.44% for 18 PAHs and the coefficient of variation (CV) are below 12.32%. Limit of quantification (LOQ) of 18 PAHs is in the range of 0.05-0.2 mg/kg. A matrix enhancement effect is observed and can be compensated with deuterated internal standard. The method has been successfully applied to 73 samples, over 40 of them are lipsticks. The results show none of the samples detect Benzo[a]pyrene (BaP) and Dibenzo[a,h]anthracene (DBA), both are classified as the most carcinogenic. 8 PAHs are detected and the average value between 0.08 and 0.27 mg/kg. This study offers a sensitive and simple method to analyze 18 representative PAHs successfully and can be applied to cosmetic products and raw materials.

气相色谱-串联质谱法测定化妆品中的多环芳烃(PAHs)

建立了气相色谱-串联质谱联用(GC-MS/MS)方法,用于测定化妆品中18种具有代表性的多环芳烃(PAHs),包括苯并[a]芘(BaP)等。该方法在选择反应监测(SRM)模式下具有高灵敏度和高选择性,可同时满足定量和定性的要求。本研究中使用的萃取溶剂系统为丙酮/己烷 1:1 (v/v),无需其他纯化程序。18 种 PAH 的线性分别在 0.25-20 ng/mL 范围内的不同浓度下得到验证,相关系数 (r) 高于 0.996。加标 3 种不同浓度的 18 种 PAH 的回收率从 87.40% 到 120.44%,变异系数 (CV) 低于 12.32%。18 种 PAH 的定量限 (LOQ) 在 0.05-0.2 mg/kg 范围内。观察到基质增强效应,可以用氘代内标进行补偿。该方法已成功应用于73个样品,其中40多个是口红。结果显示,没有一个样本检测到苯并[a]芘(BaP)和二苯并[a,h]蒽(DBA),两者都被归类为最致癌的。检测到 8 种 PAH,平均值在 0.08 至 0.27 mg/kg 之间。本研究为成功分析 18 种代表性 PAHs 提供了一种灵敏且简单的方法,可应用于化妆品和原材料。结果显示,没有一个样本检测到苯并[a]芘(BaP)和二苯并[a,h]蒽(DBA),两者都被归类为最致癌的。检测到 8 种 PAH,平均值在 0.08 至 0.27 mg/kg 之间。本研究为成功分析 18 种代表性 PAHs 提供了一种灵敏且简单的方法,可应用于化妆品和原材料。结果显示,没有一个样本检测到苯并[a]芘(BaP)和二苯并[a,h]蒽(DBA),两者都被归类为最致癌的。检测到 8 种 PAH,平均值在 0.08 至 0.27 mg/kg 之间。本研究为成功分析 18 种代表性 PAHs 提供了一种灵敏且简单的方法,可应用于化妆品和原材料。
