Abstract
Three different types of commercially available cosmetic products namely compact powder, foundation and lipstick obtained from the local shops in Sarawak were analyzed for their heavy metal contents. Wet digestion method was employed to all samples and subsequently analyzed for toxic metals (Pb, Zn, Co, Cu) by using FAAS. The results indicated that Zn is the common metal present in the entire cosmetic products. The concentration of Pb in all cosmetic samples was found to be in the safe level. As compared between countries, the highest concentration ofZn was detected in compact powder from Indonesia. Cu present only in compact powder from Malaysia in trace amount. No Cu found in foundation and lipstick samples at any price. Analysis of metals for compact powder with low price showed that the samples from china have the same content of metal detected (Pb, Co, Cu) with Indonesia samples (Zn, Co, Cu) and the least in the standard sample, A von (Zn, Cu). There was no significant trend observed for the heavy metal contents in all types ofcosmetic samples from different countries and price range.
