The U.S. Food and Drug Administration (FDA) announced recently that it is conducting a safety review of triclosan, an ingredient added to many consumer products – including liquid soaps, toothpastes, cosmetics, clothing, kitchenware, and toys – to reduce or prevent bacterial contamination. 

The FDA reiterated that triclosan is not known to be hazardous to humans, and no changes are recommended at this time. However, in light of questions raised by recent animal studies of triclosan, the FDA is reviewing all of the available evidence on triclosan's safety in consumer products.

Animal studies have shown that triclosan alters hormone regulation, although this doesn't always predict effects in humans. Other studies have raised the possibility that triclosan contributes to making bacteria resistant to antibiotics.

In an additional statement regarding the efficacy of triclosan, the FDA said there is no evidence that triclosan in antibacterial soaps and body washes provides any benefit over washing with regular soap and water. 

The FDA will communicate the findings of its review to the public in about a year.
