An on-line sweeping-MEKC method for simultaneous determination of whitening agents and parabens in commercial cosmetic products was demonstrated. This approach was shown to offer high separation efficiency, short analysis time, and convenience of analysis. The LODs of the analytes were in the range from 8 to 162 nM (1.1 to 21.0 ng mL−1) and a 46 to 279-fold enhancement was achieved.
