Abstract
Twenty-three optical brighteners have been separated on a thin-layer chromatographic (TLC) system and a high-performance liquid chromatographic (HPLC) system. These systems can be used to identify and quantitate optical brighteners in laundry detergents. The TLC system uses four solvent-absorbent combinations. The HPLC system uses a C8 column and a binary solvent gradient program to separate the optical brighteners.
