This proposal described a set of HPLC/UV procedures for the identification and quantitative determination in cosmetic products of 22 organic UV filters authorized in the EU: Camphor Benzalkonium Methosulfate (CBM), Homosalate (HS), Benzophenone-3 (BZ3), Phenylbenzimidazole Sulfonic Acid (PBS), Terephthalylidene Dicamphor Sulfonic Acid (TDS), Butyl Methoxydibenzoylmethane (BDM), Octocrylene (OCR), Ethylhexyl Methoxycinnamate (EMC), PEG-25 PABA (P25), Isoamyl p-Methoxycinnamate (IMC), Ethylhexyl Triazone (ET), Drometrizole Trisiloxane (DRT), Diethylhexyl Butamido Triazone (DBT), 4-Methylbenzylidene Camphor (MBC), Ethylhexyl Salicylate (ES), Ethylhexyl Dimethyl PABA (EDP), Benzophenone-4/Benzophenone-5 (BZ4), Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (MBP), Disodium Phenyl Dibenzimidazole Tetrasulfonate (PDT), Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (EMT), Polysilicone-15 (P-15), Diethylamino Hydroxybenzoyl Hexyl Benzoate (DHHB). They are all the currently authorized organic UV filters in the EU, with the only exception of three of them that are protected under patents and are no longer used in cosmetics (Benzylidene Camphor Sulfonic Acid, Polyacrylamidomethyl Benzylidene Camphor and 3-Benzylidene Camphor).
