The present study reports the content of 14 heavy metals (Al, Fe, Ti, Ag, As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn) in twenty-two (n = 22) lipstick products of imported and locally manufactured at the local market in Jeddah, Saudi Arabia using Inductivity Coupled Plasma-Optical Emission Spectrophotometer (ICP-OES). The overall average contents of Al, Fe, Ti, Ag, As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn were 3131.18 ± 0.09, 9642.92 ± 0.079, 46.59 ± 0.109, 0.545 ± 0.009, 2.041 ± 0.024, 1371.439 ± 0.085, 0.134 ± 0.008, 4.242 ± 0.02, ND, 3.934 ± 0.03, 19.712 ± 0.012, 20.196 ± 0.056, 0.725 ± 0.012, and 858.666 ± 0.083 μg/g, respectively. The correction coefficient of the results is up to 0.9995, showing an excellent linear relationship between metal concentrations in samples. The results also revealed that, the total concentrations of toxic metals in various samples ranged from 1201.35 - 60,800.36 μg/g. The dark-colored lipstick samples 1B, 2B, 3B, 4B, 5B, 7B, B8, 9B, and 10B revealed high content of total toxic metals compared to the light-colored lipstick samples 1A, 2A, 3A, 4A, 4C, 5A, 7A, 8A, 9A, and 10A. The concentrations of Al, Fe, Ba, and Zn in the samples within each class under investigation are relatively high whereas the concentrations of Ag, As, Cd, Co, Cu, and Pb are lowest;and Ti, Mn, and Ni contents were below 100 μg/g. Chromium was not detected in any sample. Since no safe limits for most of these metals relating to cosmetic products are available in Saudi Arabia, it is hard to ascertain whether the values obtained in this study are relatively high or low. Prolonged use of products containing these elements may pose a threat to human health and could damage the environment.
