Triclosan is a potent wide spectrum and antibacterial and antifungal agent. It is a chlorinated aromatic compound which has functional groups representative of both ethers and phenols. Phenols often show antibacterial Properties. Triclosan is found in soaps, deodorants, Toothpaste, shaving creams, mouth washes and cleansing suppliesand is included in an increasing number of consumer products.

Triclosan is very effective in reducing and controlling bacterial contamination on the hands and on treaded products. At use concentration, Triclosan acts as a biocide, with multiple cytoplasmic and membrane targets. At lower concentrations, Triclosan appers bacteriostatic and is seen to target bacteria mainly by inhibiting atty acid synthesis.

Selected Safety Data:
In classical toxicological terms, Triclosan is relatively non-toxic to humans and other animals. However, there have been reports of contact dermatitis, or skin irritation, from exposure to triclosan. There is also evidence that Triclosan may cause photoallergic contact dermatitis (PACD), which occurs when the part of the skin exposed to triclosan is also exposed to sunlight.

The dermal LD50 (the lethal dose that kills 50 percent of a population of test animals) of Triclosan for rats is 5000 mg/kg. The oral LD50 for rats is 4500-5000 mg/kg, for mice it is 4000 mg/kg, and for dogs it is over 5000 mg/kg. Triclosan has not been found to have any carcinogenic, mutagenic, or teratogenic effects. A number of recent studies have raised concerns that Triclosan and other similar products may promote the emergence of bacteria resistant to antibiotics. Laboratory studies with Triclosan have found a number of different strains of mutated bacteria that are resistant to Triclosan. It has been found to be highly toxic to different types of algae.
