The aim of this study was to determine elemental composition of various cosmetic products marketed in Turkey by X-Ray Fluorescence Spectrometry (XRFS). These cosmetic products ranged from blush, eye shadow, lipstick, nail polish, shampoo, hand cream, cellulite cream, baby powder, soap, to toothpaste (50 samples). Elements that were determined in these samples included V, Cr, Mn, Ni, Cu, As, Br, Mo, Ag, Sn, I, Hg, Pb and Bi. Metal concentration levels of Cr, As, Hg and Pb in certain cosmetic products are very important since these elements are toxic and dangerous for human health at high concentrations. In a few sample brands of cosmetic products As and Hg were detected at higher concentrations than limits defined by both German federal government and Health Canada regulations. In the majority of the samples, the concentrations of lead are higher than limits defined by both German federal government and Health Canada regulations. In lipsticks alone, 8 out of 11 brands contain Pb at concentrations higher than that of the maximum permissible concentration of 10 mu g g(-1) in cosmetics.
