Update on antibacterial soaps: the FDA takes a second look at triclosans

Area of Science:

• Environmental science
• Toxicology
• Public health

Background:

• Triclosan, a biocide, has seen widespread use since 1972, appearing in 75% of commercial soaps.
• A significant portion of the population (76% of adults and children sampled) excretes triclosan, indicating broad exposure.
• Increased triclosan use has prompted regulatory review of over-the-counter biocides.

Purpose of the Study:

• To examine the safety and efficacy of the biocide triclosan.
• To address concerns regarding the widespread use of triclosan in consumer products.
• To inform regulatory decisions by the Food and Drug Administration and Environmental Protection Agency.

Main Methods:

• Review of existing safety data on triclosan.
• Analysis of the efficacy of triclosan compared to traditional soaps.
• Investigation into potential adverse effects, including antibiotic resistance and endocrine disruption.

Main Results:

• The Food and Drug Administration announced a review of triclosan's safety and efficacy.
• Data requests were issued to gather further safety information.
• Key concerns identified include comparative effectiveness, potential for promoting drug-resistant bacteria, and endocrine-disrupting properties.

Conclusions:

• The widespread presence and excretion of triclosan necessitate a thorough safety evaluation.
• Further research is required to understand the long-term health and environmental impacts of triclosan.
• Regulatory bodies are actively assessing the risks associated with common biocides like triclosan.
