Triclosan

Triclosan is an antibacterial agent banned in EU cosmetics since 2022. It’s under EU investigation for endocrine disruption (ED List II) and persists in the environment.

What is it?

Triclosan is a synthetic antibacterial and antifungal agent. It was once one of the most common antimicrobial ingredients in consumer products. It works by inhibiting fatty acid synthesis in bacteria, but concerns about its safety and environmental impact have led to widespread bans.

Where is it found?

Historically found in antibacterial soaps, toothpastes, deodorants, and cleaning products. While banned in EU cosmetics, it may still appear in some medical devices and imported products outside EU regulation.

EU regulation

Banned in all cosmetic products in the EU since January 2022 (previously restricted to toothpaste, hand soap, and body wash at 0.3%). The ban followed SCCS opinions citing endocrine-disrupting properties and contribution to antimicrobial resistance. Triclosan is on ED List II as a substance under EU investigation for endocrine disruption.

Should you worry?

Triclosan should not appear in EU cosmetics anymore. If you find it in a product, it’s likely non-compliant or imported from outside the EU. It accumulates in the body and environment, disrupts thyroid hormones, and contributes to antibiotic-resistant bacteria. Avoid it entirely.
