A high performance liquid chromatographic method for the simultaneous determination of two additives in
o/w cosmetic formulations was developed by using HPLC and UV detection. A simple dilution procedure of the sample was required. The separation obtained for the two antioxidants was good under the chromatographic conditions used. Analysis was carried out on commercial samples, and satisfactory results were obtained for their recovery.
