Sign in to saveAlso known as Stri-Dex Cleansing Bar, CH-3565, DNDI1246774, Stri-Dex Face Wash, 2,4,4'-Trichloro-2'-hydroxydiphenyl ether, 5-Chloro-2-(2,4-dichloro-phenoxy)-phenol, Triclosanum
Triclosan (sometimes abbreviated as TCS) is an antibacterial and antifungal agent present in some consumer products, including toothpaste, soaps, detergents, toys, and surgical cleaning treatments. It is similar in its uses and mechanism of action to triclocarban. Its efficacy as an antimicrobial agent, the risk of antimicrobial resistance, and its possible role in disrupted hormonal development remains controversial. Additional research seeks to understand its potential effects on organisms and environmental health.

Triclosan was developed in 1966. A 2006 study recommended showering with 2% triclosan as a regimen in surgical units to rid patients' skin of methicillin-resistant Staphylococcus aureus (MRSA). == Uses == Triclosan was used as a hospital scrub in the 1970s. Prior to its change in regulatory status in the EU and US, it had expanded commercially and was a common ingredient in soaps (0.10–1.00%), shampoos, deodorants, toothpastes, mouthwashes, cleaning supplies, and pesticides. It also was part of consumer products, including kitchen utensils, toys, bedding, socks, and trash bags.
