Abstract:

A high performance liquid chromatography (HPLC) method was established for the determination of 22 sunscreens in cosmetics. The samples were extracted, ultrasonicated and then filtered. The target compounds were separated by OSAKA SODA CAPCELL PAK C18 MGⅡcolumn, and analyzed by HPLC with PDA detector. Under the optimized experimental conditions, there is a good linear relationship between peaks areas and sunscreens concentrations with the r values are higher than 0.999. The detection limits are in the range of 0.01%-0.11%, and the limits of quantification are in the range of 0.03%-0.34%. The average recoveries are in the range of 89.7%-109.8% with the relative standard deviations are less than 5%. This accurate and sensitive method is suitable for the qualitative and quantitative analysis of 22 sunscreens in cosmetics.

Key words: cosmetics, sunscreen, high performance liquid chromatography
