Silver

Nano silver fully banned from EU cosmetics effective Feb 1 2025 (Reg 2024/858) with market withdrawal deadline Nov 1 2025. Non-nano silver restricted from May 1 2026 to toothpaste, mouthwash, eye shadow, and lip products at specified concentrations. SCCS found micron-sized silver unsafe at higher concentrations in most cosmetics due to argyria risk (irreversible silver tissue deposition), aquatic ecotoxicity from ionic silver release, and antimicrobial resistance implications. US market lacks specific ban but FDA signaled concern. Reformulate affected EU products immediately using alternatives such as zinc PCA, copper peptides, or established preservative systems.

No specific FDA cosmetic ban on colloidal or nano silver as of 2025–2026, but FDA has warned against antibacterial silver product claims. Silver in oral care and topical products remains in legal grey zone with no GRAS classification. Aquatic toxicity and antimicrobial resistance concerns are monitored.
