Triclosan

Triclosan: The most popular antibacterial ingredient. Found in hand sanitizers, antibacterial soaps, toothpaste, and other cosmetics. When combined with water that contains trace amounts of chlorine,triclosan may form chloroform, a known carcinogen. There is also concern that triclosan’s widespread use will result in the development of resistant bacterial strains. Triclosan can react with chlorine and then sunlight to create dioxins, known endocrine disruptors. Even low-level exposure to triclosan has been showen to alter thyroid function in rats.
