A STUDY OF HEAVY METAL CONTAMINATION (LEAD, CADMIUM, NICKEL) IN THAI-BRAND BODY SUNSCREENS
Keywords:
Sunscreen, Heavy metals, Contamination, ICP-MS, Safety standardsAbstract
This experimental research by laboratory-based study focuses on analyzing the most popular commercially available sunscreen products for the body, specifically targeting the top 10 brands selected through a composite scoring method incorporating market sales data and consumer engagement metrics. Samples were subjected to microwave-assisted acid digestion (US EPA Method 3052) and analyzed using Inductively Coupled Plasma Mass Spectrometry (ICP-MS) within an ISO/IEC 17025-certified laboratory. The analytical results indicated that concentrations of Lead (Pb), Cadmium (Cd), and Nickel (Ni) in all samples were within the permissible safety thresholds established by the Thai Food and Drug Administration (Thai FDA) and aligned with the rigorous regulatory benchmarks of the U.S. FDA and the German Federal Office of Consumer Protection and Food Safety (BVL). These findings confirm the safety of leading Thai sunscreen products, demonstrating compliance with both national and international quality standards.
