Composition of eye cosmetics (kohls) used in Cairo.
A total of 18 kohl samples were analysed using X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM). All the samples were purchased in Cairo and eleven of them originated in Egypt. The main component of six samples was found to be galena (PbS); where four of these samples originated in Egypt and two in India. For a further ten samples the main component was found to be one of the following: amorphous carbon, calcite (CaCO(3)), cuprite (Cu(2)O), goethite (FeO(OH)), elemental silicon or talc (Mg(3)Si(4)O(10)(OH)(2)). For the last two samples the main component of each was an unknown amorphous organic compound.
