Quantitative evaluation of the test samples was performed using external methanolic calibration curves. Accuracy was found within the range 94.37-108.76%. The method was successfully applied to the analysis of UV filters in samples after permeability studies, in Franz's cells, for 24 h, using human skin. Concentration of sunscreens in the acceptor phase at the timescale of 24 h was very low implying the safety of the products.A reversed phase high performance liquid chromatography (RP-HPLC) method was developed for the quantitative det
