Abstract:
alpha-Tocopheryl nicotinate (alpha-TN) accelerates blood circulation and stimulates hair follicle cells, hence it is an active ingredient in a broad range of cosmetic products. A reversed-phase high-performance liquid chromatographic method was developed to determine alpha-TN in cosmetic preparations with alpha-tocopheryl acetate as internal standard. The method was found to be rapid, precise and specific.
