| Abstract: | Summary High-performance liquid chromatography (HPLC) with UV-vis detection was used for the determination of organic colorants in
cosmetic products. 126 colorants were characterized by their retention times in an ion-pair reversed-phase HPLC system with
gradient elution, and by their UV-vis spectra, recorded with a diode array detector (DAD). The method is rapid and efficient,
as is demonstrated by the analysis of 45 cosmetic samples. |
