A nonprofit environmental group has sued the U.S. Food and Drug Administration, claiming the agency failed to regulate toxic chemicals found in “antimicrobial” soap and other personal care products.

The National Resources Defense Council alleges that two common ingredients, triclosan and triclocarban, can damage reproductive organs, sperm quality and the production of thyroid and sex hormones. It also names U.S. Department of Health and Human Services Secretary Kathleen Sebelius as a defendant.

The suit was filed in U.S. District Court in Manhattan on Tuesday. Representatives of the FDA and the Department of Health and Human Services declined to comment, saying it was a matter of policy not to comment on lawsuits.

Plaintiffs contend that the FDA violated federal law in its delay over establishing safe conditions of use. More than 30 years ago, the agency first proposed to regulate such products for over-the-counter use, but they remain on the market and are unregulated, the group said.

“As a result of the FDA’s lengthy delay, consumers remain exposed to triclosan and triclocarban through a variety of over-the-counter drug products, such as antimicrobial hand soaps, that proliferate on the market,” the lawsuit stated.

The suit seeks an order requiring the FDA to finish its study on the conditions of use by a specific deadline.

No manufacturers or retailers were named as defendants or were cited in the lawsuit.

The FDA said in April it was reviewing the safety of triclosan. It noted there was no evidence it could be harmful to people and did not recommend changing consumer use of products that contain the agent.

POPULAR PRODUCTS

The popularity of antimicrobial products has grown in recent years and the products are increasingly found in homes and offices, where germs can easily be passed from person to person.

The lawsuit cites various recent studies that associate the chemicals with a host of health risks, from lower thyroid hormone levels to the disruption of testosterone production.

In 1978, according to the lawsuit, the FDA proposed to ban from interstate commerce both triclosan and triclocarban either six months or two years after publication of its final study, but no action was taken until 1994, when some ingredients were reclassified.

“Healthcare antiseptics containing these chemicals remained on the market and increased in prevalence” since 1994, the lawsuit said.

The National Resources Defense Council said it had met with the FDA to try to hasten the study, to no avail.

Responding to a letter from U.S. Rep. Edward Markey of Massachusetts in February, the FDA said it could not give a specific timeline, but said it was “working diligently” to publish the proposed rule. It also cited a lack of long-term data regarding potential health effects from exposure to the toxins.

The case is National Resources Defense Council v. USDA et al, 10 CIV 5690.
