A Comparison of Red Pigments in Different Lipsticks Using Thin Layer Chromatography (TLC)
Bhawana Joshi, Kapil Verma and Jyoti Singh
The main aim of present work is chromatographic analysis of red pigment in different well known and local brands of lipsticks. Lipstick samples of different brands of similar color were selected for this study. Coloring agent was analyzed by thin layer chromatography (TLC). Using different solvent systems [Toluene/Benzene] (4:12), Toluene/Benzene/Cyclohexane (4:12:4), Toluene/Benzene/Diethyl ether (4:4). It is hypothesized that through thin layer chromatography analysis of the red pigment in these different brands will provide no characteristic data to distinguish among lipstick sources. There is no significant difference in the hRf values among the local and well known brands of lipsticks which can be used as unique feature.
