中文摘要: 建立了测定化妆品中4种防腐剂(脱氢乙酸、氯苯甘醚、4-羟基苯甲酸苯酯、4-羟基苯甲酸苄酯)的高效液相色谱分析方法。以Diamonsil C18柱(250 mm×4.6 mm, 5 μm)作为色谱柱,以甲醇-0.1%甲酸水溶液作为流动相进行梯度洗脱,样品经甲醇-水超声提取30 min后用紫外可见可变波长检测器检测。结果表明,4种防腐剂在12.5 min内基线分离,相关系数r>0.998,平均回收率为88.5%~102.7%,日内精密度RSD<3.1%,日间精密度RSD<3.7%。该方法可用于化妆品中4种防腐剂的分析。

Abstract:A method for the determination of four kinds of preservatives (dehydroacetic acid, chlorphenesin, phenyl 4-hydroxy benzoate and benzyl 4-hydroxybenzoate) in cosmetics by high performance liquid chromatography (HPLC) was established. A Diamonsil C18 column (250 mm×4.6 mm, 5μm) was used with methanol-0.1% formic acid solution as the mobile phase under the condition of gradient elution. Samples were extracted with methanol-water solution with assistance of ultrasonic wave for 30 min, and the sample was detected by VWD detector. Results show that the four kinds of preservatives are baseline separated in12.5 min. All correlation coefficients (r) are not less than 0.998, with the average recoveries range from 88.5% to 102.7%. The intra-day precision (RSD) values are below 3.1% and inter-day precision (RSD) values are below 3.7%.
