摘要:

建立了化妆品中没食子酸丙酯、特丁基对苯二酚、叔丁基羟基茴香醚、2,6-二叔丁基-4-甲基苯酚4种合成酚类抗氧化剂含量检测的高效液相色谱分析方法。样品经超声辅助-浊点萃取,PEG-12二甲基硅氧烷(DC-193)为萃取剂,采用脂肪酸降低DC-193的浊点,壬酸体积分数为10%时最优(在浊点、相分离速度和萃取率等方面)。使用响应面法优化后,浊点萃取的较优条件为:φ (DC-193) =2.5%,超声时间30 min,平衡温度67 ℃,平衡时间57 min。结果表明,4种抗氧化剂的线性相关系数均大于0.99,低、中、高3种加标水平下的加标回收率为84%~91%,相对标准偏差为1.2%~2.3%。

Abstract:

A high performance liquid chromatography (HPLC) method was developed for the simultaneous determination of 4 synthetic phenolic antioxidants (SPAs) in cosmetics, including propyl gallate, tertiary butyl hydroquinone, butylated hydroxyanisole, and butylated hydroxytoluene. The samples were extracted by ultrasound-assisted cloud point extraction (CPE) with PEG-12 dimethylsiloxane (DC-193) as the extraction solvent. Fatty acid was added to decrease the cloud point of DC-193. When the volume fraction of nonanoic acid was 10%, it was the best in terms of cloud point, phase separation speed and extraction rate. Then multi-response surface method was used to optimize CPE. The optimum conditions of CPE were: φ (DC-193) of 2.5%, ultrasound time of 30 min, equilibrium temperature at 67 ℃, and equilibrium time of 57 min. The external standard method was used for quantification. The results show that the linear correlation coefficients of the 4 SPAs were all greater than 0.99. The average recoveries at three spiked levels were in the range of 84%-91% with RSDs of 1.2%-2.3%.
