Determination of UV filters on some sunscreen products using HPLC-DAD

الملخص EN

To evaluate twelve sunscreen products purchased from the Saudi market using HPLC-DAD method, four UV filters (benzophenone-3, octinoxate, octisalate and homosalate) was investigated.

Sample was weight, diffuse, centrifuge then analysis.

Calibration curves of standards show good linearity, R2 ranged from 0.9998 to 0.9999.

Results ranged from 1.32% to 7.88% (w/w) under the permissible limits of SASO, which confirmed the safety of creams.

Every sample has (1 to 3) sunscreen agents, while 4 creams don’t detect anyone.

The total UV filters concentrations on the same sample ranged from 2.4% to 16.88% (w/w).

HPLC-DAD method was effectively monitoring of the commercial cosmetics.
