The heavy metals test detects and quantifies harmful heavy metals (such as lead, mercury, cadmium, and arsenic) in cosmetic products and ensures that they do not pose health risks to consumers.

Regulations

Regulatory bodies, including the FDA and the EU Cosmetics Regulation, set limits on permissible concentrations of heavy metals in cosmetics to prevent toxicity and adverse health effects.

Standards and Test Methods

Commonly used testing standards include ISO 19650 and ASTM E2926. Typical methods use techniques such as inductively coupled plasma mass spectrometry (ICP-MS) or atomic absorption spectrometry (AAS) to accurately measure metal content.
