摘要： 对2015年版《化妆品安全技术规范》中防晒剂的检测方法进行改进,避免使用四氢呋喃和高氯酸,建立了以Waters Symmetry Shield RP18为分离柱,甲醇与水为流动相梯度洗脱的液相色谱方法用于测定化妆品中11种防晒剂。结果显示,在一定的质量浓度范围内,11种防晒剂的峰面积与质量浓度呈良好的线性关系,方法定量限为0.5~1.25 mg/L,回收率为98.0%~100.6%。

关键词: 化妆品, 防晒剂, 高效液相色谱法

Abstract: Method for determination of sun-screening agent specified in Safety and Technical Standards for Cosmetics (2015 Edition) was improved for avoiding the use of tetrahydrofuran and perchloric acid.The new method was established with Waters Symmetry Shield RP18 as chromatographic column,using methanol and water as mobile phase for gradient elution.All results showed good linear relationship in certain mass concentration range;the limit of quantification is within 0.5~1.25 mg/L;the spiked recoveries are within 98.0%~100.6%.

Key words: cosmetics, sun-screening agent, high performance liquid chromatography
