摘要:

建立了化妆品中24种致敏芳香化合物的气相色谱-串联质谱(GC-MS/MS)分析方法。化妆品试样经甲醇超声提取,加入无水硫酸钠脱水,经离心过滤后,采用GC-MS/MS进行分析,外标法定量。结果显示,24种致敏芳香化合物的检出限为1~28 μg/L,线性范围内相关系数均大于0.995。选取了香水、保湿水、洁面膏3种类型的化妆品作为加标基质来验证方法的准确度,24种致敏芳香化合物的加标回收率为70.1%~119.6%,相对标准偏差为0.8%~7.0%(n=6)。该方法准确、灵敏,且前处理简单、快速,适用于化妆品中24种致敏芳香化合物的测定。

Abstract:

A gas chromatography-tandem mass spectrometry (GC-MS/MS) method was developed for the simultaneous determination of 24 fragrance allergens in cosmetics. After ultrasonically extracted by methanol and dehydrated by adding anhydrous sodium sulfate, the cosmetics samples were centrifuged, filtered and analyzed by GC-MS/MS with external standard method. The limits of detection of 24 fragrance allergens range from 1 to 28 μg/L, and the correlation coefficients in the linear range were all greater than 0.995. Three types of cosmetics, including perfume, moisturizing water and cleansing cream, were selected to verify the accuracy of the method. The average spiked recoveries range from 70.1% to 119.6%, and the relative standard deviations (RSD) varies from 0.8% to 7.0% (n=6). The method is simple, rapid, accurate and sensitive, and suitable for the determination of 24 fragrance allergens in cosmetics.

Key words: gas chromatography-tandem mass spectrometry, fragrance allergens, cosmetics
