Abstract
The current paper describes the analysis of heavy metals contents in lipsticks and cosmetics being sold in Riyadh markets and compares heavy metals contents present in cosmetics of some other countries. An analytical technique called inductively-coupled plasma optical emission spectroscopy (ICP-OES) determines content for metals like As, Hg, Pb, Cd and Al in some of the most famous and widely sold lipsticks in Riyadh markets. An analysis is conducted across some expensive and some cheap brands that claim to be "organic" and "medicinal", with emphasis on the Chinese brand of lipsticks. Various parameters such as colour intensity, matte texture and glossiness, viscosity and makeup persistence were compared. Results showed serious levels of contamination from lipsticks originating from China with specimens containing above safe detectable levels. It is found that heavy metals beyond permissible limit are used in lipsticks and other cosmetic products containing fragrances and also as preservatives.
