Nearly a year has passed since the US Food and Drug Administration banned Triclosan from hand soaps and body wash in the country. But the antimicrobial and its chemical relatives are still on the ingredients list for loads of other products people in the US and internationally put on their skin and in their mouths—more than 2,000 of them, according to a statement published Tuesday (June 20) and signed by 200 doctors and scientists from all over the world.

Citing well over 100 peer-reviewed papers, they concluded that triclosan does more harm than good, and should not be in products for everyday use.

The additive was shown to be an endocrine disruptor in several animal studies—meaning it could alter hormone systems, leading to reproductive and developmental problems. In one study, male rats given triclosan had reduced testosterone and sperm production, for example. In another, female rats exposed to the chemical had miscarriages. Research has also shown that due to the indiscriminate bacteria-killing feature of triclosan and its related compounds, they have the potential to contribute to antibiotic resistance and could alter the gut microbiome.
