Background
Triclosan is a diphenyl ether (bis-phenol) derivate. It has a broad-spectrum bacteriostatic activity against a wide range of both gram-negative and gram-positive bacteria. Triclosan has found increasing and recent popular use as a preservative and disinfectant in personal care products, i.e.- toothpaste, deodorant soaps, deodorants, antiperspirants and body washes, detergents, dish washing liquids, cosmetics and anti-microbial creams, lotions and hand soaps. It is also used as an additive in plastics, polymers and textiles to give these materials antibacterial properties. Incorporated into such footwear as men's hosiery and insoles of shoes it is called an "odor-eaters" because it is claimed that this chemical can suppress the odor produced by foot organism.
Triclosan is very easily absorbed, even through the skin and a stady state is reached quickly. Although Triclosan can cause an allergic contact dermatitis, particularly when used in products for the feet, in practice it rarely causes sensitisation or skin irritation.
