Kozmetika - Analizne metode - Metoda LC/UV za identifikacijo in kvantitativno določevanje 22 organskih UV-filtrov, ki se v EU uporabljajo v kozmetičnih izdelkih
Ta predlog je opisal niz postopkov HPLC/UV za identifikacijo in kvantitativno določevanje 22 organskih UV-filtrov, ki so v EU odobreni za uporabo v kozmetičnih izdelkih: benzalkonijev metasulfat kafra (CBM), homosalat (HS), benzofenon-3 (BZ3), fenilbenzimidazol sulfonska kislina (PBS), tereftaliden dikafra sulfonska kislina (TDS), butilmetoksi dibenzoilmetan (BDM), oktokrilen (OCR), etilheksil metoksicinamat (EMC), PEG-25 PABA (P25), izoamil p-metoksicinamat (IMC), etilheksil triazon (ET), drometrizol trisiloksan (DRT), dietilheksil butamidotriazon (DBT), 4-metilbenziliden kafra (MBC), etilheksil salicilat (ES), etilheksildimetil PABA (EDP), benzofenon-4/benzofenon-5 (BZ4), metilen bisbenzotriazolil tetrametilbutilfenol (MBP), dinatrijev fenil dibenzimidazol tetrasulfonat (PDT), bisetilheksiloksifenol metoksifenil triazin (EMT), polisilikon-15 (P-15), dietilamino hidroksibenzoil heksil benzoat (DHHB). To so vsi trenutno odobreni organski UV-filtri v EU, z izjemo treh, ki so zaščiteni s patenti in se ne uporabljajo več v kozmetičnih izdelkih (benziliden kafra sulfonska kislina, poliakrilamidometil benziliden kafra in 3-benziliden kafra).

For difficult-to-solve samples, the use of ultrasound or vortex can help. After that, depending on the UV filters to be determined, aliquots are taken and diluted with a mixture of ethanol:acetate buffer, ethanol or tetrahydrofuran for the determination of the water-soluble group, the fat-soluble group or P15 (which is a polymer), respectively. Regarding the water-soluble group, the 6 UV filters are measured by employing a reversed-phase column and a mobile phase of ethanol and acetate buffer. Regarding the fat-soluble group, the 15 UV filters are determined by employing a reversed-phase column and a mobile phase of ethanol and aqueous formic acid containing hydroxypropyl-beta-cyclodextrin as mobile phase modifier. Finally, for P15 determination, a size-exclusion column and tetrahydrofuran as mobile phase are used. 5 Reagents If not otherwise specified, analytical-grade chemicals shall be used. 5.1 Ethanol (EtOH), LC-grade. 5.2 Tetrahydrofuran (THF), LC-grade. 5.3 Deionized water, 18,2 ·cm resistivity. 5.4 2-Hydroxypropyl--cyclodextrin (HP--CD), 1 309 g/mol molecular weight. 5.5 Formic acid, 98 %, d = 1,22 g/ml. 5.6 Glacial acetic acid, > 99 %, d = 1,05 g/ml. 5.7 Sodium hydroxide, pellets. 5.8 Sodium hydroxide, 10 % (w/w) aqueous solution.
