It’s a chemical that’s been in U.S. households for more than 40 years, from the body wash in your bathroom shower to the knives on your kitchen counter to the bedding in your baby’s bassinet.
But federal health regulators are just now deciding whether triclosan — the germ-killing ingredient found in an estimated 75 percent of antibacterial liquid soaps and body washes sold in the U.S. — is ineffective, or worse, harmful.
The U.S. Food and Drug Administration is planning to deliver a review this year of whether triclosan is safe. The ruling, which will determine whether triclosan continues to be used in household cleaners, could have implications for a $1 billion industry that includes hundreds of antibacterial products from toothpaste to toys.
The agency’s review comes amid growing pressure from lawmakers, consumer advocates and others who are concerned about the safety of triclosan. Recent studies of triclosan in animals have led scientists to worry that it could increase the risk of infertility, early puberty and other hormone-related problems in humans.
“To me it looks like the risks outweigh any benefit associated with these products right now,” said Allison Aiello, professor at the University of Michigan’s School of Public Health. “At this point, it’s just looking like a superfluous chemical.”
The concerns over triclosan offer a sobering glimpse at a little-known fact: Many chemicals used in everyday household products never have been formally approved by U.S. health regulators. That’s because many germ-killing chemicals were developed decades ago before there were laws requiring scientific review of cleaning ingredients.
The controversy also highlights how long it can take the federal government to review the safety of such chemicals. It’s not uncommon for the process to drag on for years, since regulators must review volumes of research and take comments from the public on each draft.
Johnson & Johnson has pledged to remove triclosan from all of its adult products by the end of 2015. The company says none of its baby products currently contain the ingredient.
