DIRECT DETERMINATION OF NATURAL AND SYNTHETIC ANTIOXIDANTS IN COSMETIC CREAMS BY GAS CHROMATOGRAPHY. Authors: . |
||||||
Abstract: A gas chromatographic method for the simultaneous determination of two additives in o/w cosmetic formulations was developed by using GC and FID detection. A simple dilution procedure of the sample was required. The separation obtained for the two antioxidants was good under the chromatographic conditions used. Their analysis was carried out in commercial samples, and satisfactory results were obtained for the recovery of this compounds. Keywords: cosmetic product, antioxidants, antiradical activity, chromatographic anlysis methods, gas chromatography. |
