| Abstract: | A identification method of lipstick by thin - layer chromatography is reported in this paper. The coloring materials are extracted from lipstick by a 95% (v/v) ethanol aqueous solution and separated by a solvent in which the volume ratio of ethyl acetate: methanol: water is 3. 6: 2.2: 1.2. By observing and analysing the colority, fluorescent characteristic, number and flow rate of the color spots, the assortment of a lipstick and its manufactory can determined. |
