I’ve written here a number of times over the past couple of years (most recently here) about triclosan, an anti-bacterial and anti-fungal agent that is used in a wide variety of consumer products, including anti-bacterial soaps, toothpaste, deodorant, mouthwash, other cosmetic products, and household cleaning supplies. The US Food and Drug Administration [FDA] has been conducting a safety and effectiveness review of triclosan for some time now. The review was originally scheduled to be released in April, 2011; last summer, it was promised by the end of the year (2012). We’re all still waiting.
The Singularity Hub site has an article on this ongoing saga. It gives a bit more of the history: the FDA issued draft guidelines in 1978, which classified triclosan as “not generally recognized as safe and effective”. Since the guidelines were never finalized, nothing changed.
The FDA has not given an updated timetable for the release of its review.
