Triclosan

Also known as: TCS, Irgasan

High ConcernantimicrobialEWG: 7-10

An antimicrobial agent banned by the FDA in hand soaps — an endocrine disruptor that contributes to antibiotic resistance.

How it works

Triclosan inhibits bacterial fatty acid synthesis. It was widely used in hand soaps, toothpastes, and cosmetics. The FDA banned it from OTC hand soaps in 2016 citing lack of safety evidence and endocrine disruption. It interferes with thyroid hormone function, is detected in human blood and breast milk, and contributes to the development of antibiotic-resistant bacteria.
