Determination of Five Kinds of Ultraviolet Absorbents in Cosmetics by Ultra Performance Liquid Chromatography / 环境与健康杂志

0.999,the limits of detection of five ultraviolet absorbents were 4 to 6 mg/L and the minimum detectable concentration was 0.01%-0.015%.The rates of recovery for this method ranged from 98.35% to 102.75% and the relative standard deviations of this method were 0.44% to 1.73%.Conclusion The method is simple,rapid,accurate and applicable to simultaneous determination of the five ultraviolet absorbents in cosmetics.
