  Abstract:  A gas chromatographic method for the simultaneous determination of two antioxidants in o/w („oil in water”) cosmetic formulations was developed by using GC with FID detection. A simple extraction procedure of the sample was required. The sample treatment proposed consists of dissolving the oil-rich products sample (Anti-Wrinkle Eye Contour Cream, Intensive Moisturizing Day Lift Cream and Replenishing Night Lift Cream) by sonication with organic solvent, centrifugation and filtration of the supernatant. The analytes were separated on a fused silica capillary column coated with DB-5 (5% diphenyl-95% dimethylpolysiloxane) and good separation was obtained for analysed antioxidants. The analysis was carried out in commercial samples, and satisfactory results were obtained for the recovery of this compounds.

Keywords: cosmetic product, antioxidants, GC-FID.
