We study here the contamination of Rhassoul, an inexpensive clay mineral readily available inmany places of theAtlasMountains inMorocco. It used for centuries in various cosmetics (embellishment of skin and hair) and is thus non-toxic. Many people add various herbs or other substances to the Rhassoul in order to strengthen it. Our results showed that the concentration of Lead and copper found in non-elaborate samples of Rhassoul were low. However, when Rhassoul was mixed with other products, these concentrations increased.
