| Description | Triclosan is an antibacterial and antifungal agent. It is a polychloro phenoxy phenol. It is widely used as a preservative and antimicrobial agent in personal care products such as soaps, skin creams, toothpaste and deodorants as well as in household items such as plastic chopping boards, sports equipment and shoes. According to the Food and Drug Administration (FDA) at the present time there is no evidence that triclosan in personal care products provides an extra benefit to health beyond its anti-gingivitis effect in toothpaste. The FDA does not recommend changing consumer use of triclosan containing products one way or the other due to currently insufficient safety evidence. Studies by the Environmental Protection Agency (EPA) found triclosan to be an effective antibacterial. Triclosan safety is currently under review by the FDA and Health Canada. Triclosan is only found in individuals that have used or taken this drug. |
