A fastHigh Performance Liquid Chromatography (HPLC) method was developed and validated for the simultaneous quantitative determination of phenylbenzimidazole sulfonic acid (PBMSA), benzophenone-3 (BZ3), diethylamino hydroxybenzoyl hexyl benzoate (DHHB), octocrylene (OC), butyl methoxydibenzoylmethane (BMBM), ethylhexyl methoxycinnamate (EMC), ethylhexyl salicylate (ES), and homosalate (HS) which are eightorganic UV-filters of the most commonly used in cosmetics and sunscreens. A solution pH 2.0 of phosphate buffer, methanol, and acetonitrile in proportions 15:3:82 respectively as mobile phase was used in isocratic conditions, combined with a Purospher Star ® Performance RP-18e column and eight minutes of analysis time. The proposed method was validated following the recommendations of International Council on Harmonization (ICH) and the Food and Drug Administration (FDA) guidelines. All parameters examined were found to be well within the stated guidelines. From the robustness test, it was possible to identify that pH of the buffer and the vial material are the critical methodological parameters for the analysis of butyl methoxydibenzoylmethane (BMBM), whereas for phenylbenzimidazole sulfonic acid (PBMSA) they were, the vial material, volume ofNaOH solution and sonication time and temperature.
