A study of the composition of some eye cosmetics (kohls) used in the United Arab Emirates.
Abstract A total of 23 kohl samples was analyzed using X-ray powder diffraction (XRPD) and scanning electron microscopy (SEM). Nineteen samples were obtained in Abu Dhabi and four in Dubai. None of the samples were made in the United Arab Emirates. The main component of 11 samples was found to be galena (PbS). For the remaining 12 samples, the main component was found to be one of the following: amorphous carbon, zincite (ZnO), sassolite (H 3 BO 3 ) or calcite/aragonite (CaCO 3 ).
