Chlorinated aromatic biocide

Triclosan is a biocide widely used in disinfectants, soaps and deodorants. It is found in cosmetics as preservatives and is used for antimicrobial treatment of textiles.
Because of its broad use there is some concern about the development of resistant and cross-resistant bacterial strains. Triclosan may be transformed into polychlorinated dibenzodioxins and dibenzofurans upon exposure to UV light. The environmental relevance of this process is not clear.

Triclosan is toxic to aquatic organisms, especially to algae.
