Eye shadows are cosmetic products widely used to enhance appearance. However, the use of raw materials contaminated with heavy metals poses potential health hazards. This study characterized 12 commercial eye shadow samples and quantified concentrations of Al, Ba, B, Cu, Cr, Fe, Mn, Ni, Pb, V, and Zn using inductively coupled plasma mass spectrometry (ICP-MS). Additional characterization using UV-vis, ATR-FTIR, and SEM-EDS techniques provided insights into the composition and potential sources of contamination. Multivariate analysis revealed differences in metal concentrations across brands. Health risk assessments, including margin of safety (MoS), hazard quotient (HQ), hazard index (HI), lifetime cancer risk (LCR), and lifetime cancer risk based on the long-term relevant daily systemic exposure dose (LCR′), indicated that one product may pose significant health risks. Specifically, sample M4 showed an HI of 2.67 × 101, exceeding acceptable limits. These findings highlight the need for stricter regulation and continuous monitoring of heavy metals in cosmetics to safeguard consumer health.
