摘要
用反相高效液相色谱法在20min内同时测定化妆品中11种防晒剂。色谱柱为YWG-C18柱,流动相为甲醇-四氢呋喃-水-高氯酸(2002001600.1,V/V),检测波长为311nm。报告了对103种防晒化妆品测定的结果。
A method for quantitative determination of eleven sunscreen agents (benzophenone 4,p amino benzoic acid, salicylic acid, benzophenone 3,phenyl salicylate, 4 methylbenzylidene camphor, octyl dimethyl p amino benzoate, isopropyl dibenzoylmethane, butyl methoxydibenzoylmethane, octyl methoxycinnamate, octyl salicylate)in cosmetic products is described. It was based on a high performance liquid chromatographic separation under the condition of isocratic elution with a mixture solution of methanol THF water 70% perchloric acid (200∶200∶160∶01) by using a column packed with 10μm YWG C18 and UV detection. The recoveries (n=6) were 941% 101% and the relative standard deviations(n=6) for all eleven sunscreen agents were less than 5%. In addition, the results of analysis of 30 samples out of 103 samples of commercial suntan cosmetics performed are reported in this paper.
