It is used to reduce to reduce or prevent bacteria, fungi, and mildew growth. Triclosan can be found in clothing, kitchenware, furniture, and toys. It may also be used in antibacterial soaps and body washes, toothpaste, and cosmetics. It was first introduced as a pesticide in 1969.

Recent studies show the possibility of Triclosan making bacteria resistant to antibiotics as well as possible serious health concerns. Studies found in administering 1% of what is considered a lethal amount of Triclosan to animals to a mouse, it died of heart failure within one minute. The dose was lowered for the remaining mice and it still reduced the heart's ability to circulate blood and reduced leg muscle strength. The FDA is taking these and other studies into consideration and is reviewing Trisclosan.

Testing is being reviewed for endocrine effects, developmental and reproductive toxicity and carcinogenicity.
