摘要

The presence of heavy metals in cosmetics is concerning due to their potential health risks. Lead, mercury, arsenic, cadmium, and other heavy metals can be found in minute quantities in some cosmetics, often as impurities from raw materials or as contaminants introduced during manufacturing. The study involved the analysis of 65 different types of unbranded cosmetics samples collected from inner markets of Lahore (Pakistan), near border areas of sub-continent. These products included lipsticks, eyeshadows, highlighters, and compact powders from various manufacturers and countries. The makeup was digested using an effective method that allowed for the thorough digestion of all types of products while ensuring that the sample heating temperature did not exceed 95 °C. Heavy metal analysis, specifically for Cr(VI), As(III), Cd(II), Ni(II) and Pb(II) was conducted by atomic absorption spectrometer, using microwave assisted acid digestion method for sample preparation. Additionally, a vapor generation assembly (VGA) was employed for the detection of arsenic due to hydride generation. Heavy metals were detected mostly in lipsticks and eyeshadows samples, especially a high amount of Cr (VI) is detected in eyeshadows. Using these cosmetics can have adverse effects on the skin, leading to dermatitis, scabies, hyperpigmentation, endocrine disruptions and neural disorders.
