【摘要】 目的:了解深圳市售化妆品中使用防腐剂种类及重金属含量情况。方法:采用HPLC法、FPD-GC法、分光光度法分析分妆品中9种防腐剂。采用ICP-MS法分析化妆品中的Pb As Cd Hg。结果:化妆品中最常用的防腐剂是对羟基苯甲酸酯类:祛斑类化妆品样品中汞含量严重超标;FPD-GC法测定卡松的检出浓度为0.75μg/g,HPLC法测定卡松的检出浓度为4μg/g;甲醛检出率37%。结论:FPD-GC法测定卡松灵敏度较高。甲醛检出率较高,可能与某些防腐剂释放甲醛有关。更多还原

【Abstract】 Objective:To understand both the kinds of preservatives and contents of heavy metal in cosmetic.Methods:The content of 9 preservatives in cosmetics were determined by HPLC,FPD-GC and Spectrophotometry.The determination of As,Cd,Pb and Hg was analysed by ICP-MS.Results:It was clear that the most popular preseratives of cosmetics were parabens,the content of mercury exceeded the standard seriously in the cosmetics sample,the lowest detection concentration of Kathon was 0.75μg/?g when using FPD-GC,it was 4μg/?g when using HPLC,the detectable rates for formaldehyde was 37% in the samples.Conclusion:In these methods for kathon detection,FPD-GC is more senstitive.The free formaldehyde in cosmetic products are released by certain formaldehyde releaser.更多还原
