Risk assessment of heavy metals in lipstick and hair dye cosmetics products in Sanandaj

Human exposure to heavy metals causes health problems and use of cosmetic products; especially lipstick and hair dye contaminated by metals is considered a way of exposure to these agents. The aim of this study was to determine concentrations of heavy metals in lipstick and hair dye cosmetics products in Sanandaj.
Material and This study was a cross - sectional study and performed from Jan to Feb, 2015. In this study we collected 50 samples from four brands of lipstick and hair dye in Sanandaj. After preparation of the samples by acid digestion, the concentrations of heavy metals were measured by using ICP-OES and the results were reported in microgram per gram.
The results showed that the mean concentrations of cadmium, iron and zinc in the hair dyes were higher than those in the lipsticks; while the mean concentrations of, copper, nickel and lead in the lipsticks were higher than those in the hair dyes. Moreover, among the metals iron had the highest and silver and cadmium had the lowest concentrations in both of the cosmetic products. HQ index in this study was less than 1.
The metal concentrations in the lipstick and hair dye cosmetics products in Sanandaj were generally lower than the maximum acceptable concentration in the US and Canada. Considering the potential effects of metals on health, it is essential to control import of these products into the country and establish national standards for cosmetics.
