FDA demands evidence on effectiveness of antibacterial soaps

The Food and Drug Administration has issued a proposed rule to require manufacturers of antibacterial hand soaps and body washes to demonstrate that their products are safe for long-term daily use and more effective than plain soap and water in preventing illness and the spread of certain infections.

Under the proposal, if companies do not demonstrate such safety and effectiveness, these products would need to be reformulated or relabeled to remain on the market.

The action taken Monday, Dec. 16, is part of a larger, ongoing review of antibacterial active ingredients by the FDA to ensure these ingredients are proven to be safe and effective.

The proposed rule does not affect hand sanitizers, wipes or antibacterial products used in healthcare settings, the FDA noted.

Millions of Americans use antibacterial hand soap and body wash products. Although consumers generally view these products as effective tools to help prevent the spread of germs, there is no evidence that they are more effective at preventing illness than washing with plain soap and water, according to the FDA.

Further, some data suggest that long-term exposure to certain active ingredients used in antibacterial products — for example, triclosan (liquid soaps) and triclocarban (bar soaps) — could pose health risks, such as bacterial resistance or hormonal effects.

“Antibacterial soaps and body washes are used widely and frequently by consumers in everyday home, work, school and public settings, where the risk of infection is relatively low,” Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research, said in a news release. “Due to consumers’ extensive exposure to the ingredients in antibacterial soaps, we believe there should be a clearly demonstrated benefit from using antibacterial soap to balance any potential risk.”

Under the proposed rule, manufacturers who want to continue marketing antibacterial products will be required to provide the agency with additional data on the products’ safety and effectiveness, including data from clinical studies to demonstrate that these products are superior to non-antibacterial soaps in preventing human illness or reducing infection.

“While the FDA continues to collect additional information on antibacterial hand soaps and body washes, we encourage consumers to make an educated choice about what products they choose to use,” Sandra Kweder, MD, deputy director, Office of New Drugs at CDER, said in the news release. “Washing with plain soap and running water is one of the most important steps consumers can take to avoid getting sick and to prevent spreading germs to others.”

Consumers should continue to be diligent about washing their hands, the FDA stated. If soap and water are not available, an alcohol-based hand sanitizer that contains at least 60% alcohol should be used.

Almost all soaps labeled “antibacterial” or “antimicrobial” contain at least one of the antibacterial ingredients addressed in the proposed rule. The most common active ingredients in antibacterial soaps are triclosan and triclocarban. Some soaps labeled “deodorant” may also contain these ingredients.

The proposed rule does not require the antibacterial soap products to be removed from the market. When the proposed rule is finalized, companies must provide data to support an antibacterial claim or reformulate (remove antibacterial active ingredients) or relabel (remove the antibacterial claim from the product’s labeling) these products to continue marketing.

The proposed rule is available for public comment for 180 days, with a concurrent one year period for companies to submit new data and information, followed by a 60-day rebuttal comment period.
