FDA scientists developed and validated a highly sensitive method for the analysis of total lead content in lipstick and applied the method to the same lipsticks, that were still available on the market, previously evaluated by the CSC. FDA scientists found lead in all of the 20 lipsticks tested, ranging from 0.09 ppm to 3.06 ppm, with an average value of 1.07 ppm. The detection limit was estimated to be 0.04 ppm. FDA concluded that the lead levels found are within the range that would be expected from lipsticks formulated with permitted color additives and other ingredients that had been prepared under good manufacturing practice conditions.
