中文摘要:

      建立了同时测定化妆品中23种香料致敏成分的高效液相色谱法。样品经乙腈超声提取15min,以8000r/min离心5min,取上清液过滤后测定。采用Aglient ZORBAX SB-C18(4.6×250 mm,5μm)色谱柱, 以乙腈-水为流动相梯度洗脱,采用二极管阵列检测器多波长检测(200、210、240、290nm)。23种致敏成分的定量限分别为1.25、2.5、5.0、10.0μg/kg,线性范围内相关系数均大于0.99。在1倍定量限、2倍定量限,10倍定量限浓度的添加水平下平均回收率为80%-110%,相对标准偏差为0.5%-9.3%。该方法简单、准确、快速,适用于化妆品中23种致敏成分的测定。

英文摘要:

      A high performance liquid chromatographic (HPLC) method was developed for the simultaneous determination of 23 perfume allergens in cosmetics. The cosmetic samples were extracted supersonically with acetonitrile for 15 minutes and centrifuged at 8000 r/min for 5min. The supernatant was separated on an Aglient Zorbax SB-C18 column (4.6×250mm, 5μm) by gradient elution with acetonitrile-water. The analysis of 23 allergens was performed by HPLC with diode array detector at the wavelength of 200, 210, 240, 290 nm, respectively. The limits of quantitation of 23 allergens were 1.25、2.5、5.0、10.0 μg/kg. The method showed a good linearity with correlation coefficients above 0.99. The mean recoveries at three spiked levels were in the range of 80% - 110% with RSDs of 0.5% - 9.3%. The method is accurate, rapid and suitable for the determination of 23 perfume allergens in cosmetics samples.
