Triclosan
Also known as: 5-Chloro-2-(2,4-dichlorophenoxy)phenol
Last updated:
Triclosan is an antimicrobial agent historically used in soaps, deodorants, and toothpaste. The FDA banned triclosan from US OTC consumer antibacterial soaps in 2016 (final rule), citing lack of evidence of efficacy and concerns about antimicrobial resistance and endocrine effects. The EU permits triclosan only in specific product categories (toothpaste, hand and body soaps, deodorants, face powders) at up to 0.3% (Annex V #25).

Safety profile
Triclosan can disrupt thyroid hormone function in animal studies. It is also persistent in the environment and contributes to antimicrobial resistance. The FDA's 2016 rule removed triclosan from the OTC monograph for consumer antibacterial soap and body wash. Toothpaste containing triclosan remains FDA-approved (Colgate Total) where efficacy is established.
Common uses
- Preserved categories (EU): toothpaste, hand/body soap, deodorant, face powder
- Historically widespread in antibacterial soap (now banned in US OTC)
- Medical-device cleansers (separate regulatory pathway)
