April 9, 2010 -- With the FDA reviewing the antibacterial chemical
triclosan, widely found in everyday products such as hand soaps, body washes,
toothpastes, cosmetics, toys, clothing, and furniture, should you or shouldn't
you ditch products with this ingredient?
Here are the most frequently asked questions about triclosan, with answers
from experts on both sides of the debate, to help you decide.
Triclosan is a chemical added to many products for its antibacterial
''It's been in use for over 40 years," says Brian Sansoni, a spokesman for
the Soap and Detergent Association, whose members produce soaps and body
washes. Initially, its use was only in health care settings such as hospitals,
In the last 15 years, triclosan began showing up in consumer hygiene
products, he says.
The FDA announcement this week about triclosan was in response to a letter
from Rep. Edward J. Markey, chairman of the House Energy and Commerce
Subcommittee on Energy and the Environment.
Markey had sent the letter in January, requesting information about the
status of the FDA's ongoing review of triclosan in consumer products.
Markey is concerned and is calling for the FDA to ban the use of triclosan
in personal care products. He wants the Environmental Protection Agency to take
steps, too, such as evaluating the potential of triclosan -- washed down the
drain with personal care product use -- to contaminate drinking water and
contribute to antibiotic resistance.
Triclosan ''is not known to be hazardous to humans," according to the FDA
statement issued this week.
In 1997, the FDA reviewed data on triclosan in one specific toothpaste,
Colgate Total, and found that the triclosan in it was effective in preventing
gingivitis, the inflamed gum condition that marks the beginning of periodontal
(Markey has asked the FDA to re-evaluate this approval, as the review was
done before health concerns arose about triclosan.)
As for triclosan added to soaps and body washes, the FDA say there is no
evidence that these products provide any extra health benefits over plain soap
The FDA say it is continuing to review the safety of triclosan in the
products it regulates. It is partnering with the EPA to study the effects on
"We want it removed because it is ineffective and poses a potential threat
to human health and the environment," Sarah Janssen, MD, PhD, a staff scientist
at the Natural Resources Defense Council, tells WebMD.
In animal studies, triclosan has been found to interfere with hormones
crucial for normal brain development and function and reproductive system
development and function, Janssen says.
That interference could be serious, she says, leading to altered behavior,
learning disabilities, and infertility.
The development of antibiotic resistance with continuous use of the products
with triclosan is another concern, she says.
''The other big concern is, because of its widespread use in consumer
products, we now have widespread contamination of the U.S. population with this
chemical," Janssen says. ''Three-quarters of Americans are carrying traces of
it in the blood."
She is referring to a study, published in 2007, in which researchers from
the CDC found that three-quarters of more than 2,500 urine samples from U.S.
children and adults had various concentrations of triclosan.
''We have seen absolutely no clear evidence that use of triclosan or any
other antibacterial ingredient is leading to hormone problems in human beings,"
Sansoni says. "It's a great leap," he says, to go from animal study results to
human study results.
Products with triclosan, he says, ''are widely available and are continually
used safely and effectively by millions of people in hospitals, offices, homes,
and day care settings."
''We think it's important for consumers to continue to have access," Sansoni
For now, according to the FDA, there is not enough evidence to recommend
avoiding the products. The FDA expects to release the findings of its review of
the ingredient's safety in spring of 2011.
Simply by reading the label. Triclosan will be listed in the ''drug facts''
Sansoni says products with the ingredient are also likely to include other
information elsewhere on the label, pointing out the antibacterial action.
