| 摘 要： | 采用反相高效液相色谱-二极管阵列检测器同时测定美白日霜中的4-甲基苄亚基樟脑、丁基甲氧基肉桂酸乙基己酯和甲氧基肉桂酸乙基己酯3种防晒剂。结果表明,以上3种防晒剂在所考察的质量浓度范围内具有良好的线性,R2分别为1.000 0,0.999 9和1.000 0,平均加样回收率分别为102.20%、100.00%和98.30%,相对标准偏差分别为1.60%、1.81%和1.47%。该方法可以较好地检测不含蜡质化妆品中的化学防晒剂含量。

| Abstract: | A reverse-phase high performance liquid chromatographic method with diode-array detector was established to simultaneously determine 4-Methylbenzylidene Camphor,Butyl Methoxydibenzoylmethane and Octyl Methoxycinnamate in cosmetics.Results demonstrated that the 3 aforementioned UV filters showed favorable linearity in researched range,with R2 of 1.000 0,0.999 9 and 1.000 0 respectively;While average recoveryrates are 102.20%,100%,83.30% and RSD1.60%,1.81%,1.47% respectively.The method is suitable for cosmetic without wax |
