CBS 111, 7-9 (2013). HPTLC of benzophenone-3 (BP-3), butyl methoxydibenzoyl-_x000D_methane (BM-DBM), 3-benzylidene camphor (3‑BC), 4‑methylbenzylidene camphor (4‑MBC), octocrylene (OCR), ethylhexyl methoxycinnamate (EHMC), ethyl-hexyl salicylate (EHS), diethylhexyl butamido triazone (DEBT), octyldimethyl p-aminobenzoic acid (OD-PABA), 2-hydroxy-4-methoxy-benzophenone-5-sulfonic acid (HMBS), ethylhexyl triazone (EHT) on amino phase with petroleum ether - t-butyl-methyl ether - methanol 7:2:1 and 1 % triethylamine (HMBS with methanol – acetic acid 9:1), migration distance max. 48 mm from lower edge. For reaction with the UV filters the plate was stored up to 2 h in a dark at room temperature, then heated to 33 °C, and irradiated under natural sunlight or with a Suntest CPS+ at 350 W/m2. Quantitative absorbance measurement at UV 254 nm. The UV filters known as common triggers for photoallergic reactions showed the greatest tendency to bond to the amino phase. Thus, the developed screening method is well suited to estimate the potential of_x000D_ different UV filters to form protein adducts and to identify possible skin sensitizers.
