ABSTRACT: This study focuses on the determination, as well as, the composition of some heavy metals contained in 12 eye shadow cosmetic samples. An elemental analysis of heavy metals (Ti, Cr, Fe, Ni, Cu, Co, Mn, Pb, and Zn) was performed by X-ray Fluorescence. The constitution of some samples was studied by Powder X-Ray Diffraction. Heavy metals exist as zinc oxide, Titanium dioxide, Iron oxide, Bismuth oxychloride, and lead sulfide. The quantification of selected toxic heavy metals lead, copper and nickel were achieved by Inductively Coupled Plasma-Optical Emission Spectrometry after digestion with concentrated acids. In all analyzed samples lead had a concentration less than 20 ppm, which indicated good manufacturing practice. Copper and nickel levels were within
acceptable concentrations, but overpasses the safe limit appeared in China samples. The prolonged use of cosmetics case an allergic problem for consumers. Therefore, quality controls are highly controlled for imported products with different regulations.
