Triclosan and Triclocarban (Antibacterials)

Health concerns
Triclosan has been shown to with thyroid hormone, which is vital for the development of the brain and nervous system and regulates energy balance in adults.  and sex hormones. Triclocarban has been shown to interfere with thyroid and sex hormones. These chemicals may accumulate in the fatty tissues of the body, such as breast tissue, and be secreted into breast milk. Nearly three-quarters of the U.S. population carries residues of triclosan in their body. Widespread use of antibacterial chemicals has the potential to lead to the development of strains of bacteria resistant to multiple antibiotics, or “superbugs.”

Environmental concerns
In the environment, antibacterial compounds disrupt aquatic ecosystems and persist in the soil, posing a potential risk to wildlife.

Where they are found
These antibacterials are used in a number of household and personal-care products, including cosmetics, liquid hand soap, deodorant bar soap, sponges, toothpaste and cutting boards, as well as shoes, towels and clothes. They are often listed among the ingredients of personal-care products.

Stay safe
Avoid antibacterial hand soaps and other products labeled as containing triclosan or triclocarban.
Avoid clothing, towels or shoes containing microban or advertised as “antimicrobial.”
Use regular soap and water to clean—it’s just as effective, and it doesn’t carry any health or environment risks.

The big picture
Soap and water is just as effective at killing bacteria as antimicrobial chemicals. There’s simply no need to infuse bath towels, yoga mats or cutting boards with unnecessary and potentially harmful substances. The FDA is sitting on a draft paper that demonstrates this, but until the agency publishes it, manufacturers are allowed to continue using these chemicals at will. NRDC is spreading the word about the lack of effectiveness and potential harm of triclosan and triclocarban, while urging the FDA to finalize the paper and end their widespread use.
