Composition of eye cosmetics (kohls) used in Oman.
A total of 47 kohl samples, primarily used as traditional eye cosmetics, were analyzed using X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM). It was found that, of the 18 Omani-made kohls, the main component of five was galena (PbS). Of the other 13, 12 were based on amorphous carbon and one on hematite (Fe2O3). The remaining samples were made in other countries and were found to contain one of the following as the main component: galena, minium (Pb3O4), amorphous carbon, magnetite (Fe3O4), zincite (ZnO), calcite (CaCO3) or sassolite (H3BO3).
