Abstract:

A method for simultaneous determination of 14 sunscreen agents in sunscreen cosmetics was established by gas chromatography, with ultrasonic extraction of sunscreen agents in sunscreen cosmetics carried out by DB-5MS capillary column separation and hydrogen flame ionization detector. The results show that the linearity of 14 sunscreen agents is good in the range of 0.5-100.0 mg/kg, and the correlation coefficients are more than 0.999 3. The detection limit is 0.05-0.15 mg/kg, the limit of quantification is 0.17-0.50 mg/kg; the relative standard deviation is 1.1%-3.1%, and the recovery rate of the spiked standards are 91.7%-100.1%. The method has the advantages of simple operation, high recovery rate, good precision and low detection limit, and can provide a detection method for determining the type and content of the sunscreen agent in the sunscreen cosmetic.

Key words: sunscreen agents, sunscreen cosmetics, gas chromatography
