Not toxic, not irritating to skin and eyes, when used in formulations. - Not sensitizing. 

Not carcinogenic. Not mutagenic. Not toxic to reproduction. Not teratogenic. No accumulation in organs or tissues complete elimination. 

Tests with activated sludge (batch and continuous tests) at environmentally relevant Triclosan concentrations demonstrate nearly complete removal of the microbicide from waste water, largely as a result of biodegradation.

Triclosan is a chlorinated derivative of phenol and its chemical name is 5-chloro-2-(2,4-dichlorophenoxy)phenol and its chemical formula is C 2H7Cl,02. Phenol is a benzene ring with a hydroxy group attached, chemical formula C6H5OH, and triclosan has two such rings in the molecule.

The chlorophenoxyalkanoic acids constitute yet another economically important group of halogenated aromatic hydrocarbons. They are widely used as herbicides to control dicotyledonous weeds. The most important of them are 2,4-D and its propionic and butyric acid homologs, 4-chloro> 2-methylphenoxyacetic acid (MCPA), and 2,4,5>trichlorophenoxyacetic add (2,4,5-T). In all the cases studied, aerobic biodegradation proceeds by removal of the aliphatic side chain with the formation of the corresponding chlorinated phenoL Thus, formation of 2,4 chlorophenol from both 2,4-D and 4-(2,4-dichlorophenoxy)-butyric acid, 4-chloro-o-cresol from MCPA, and 2,4,5-trichlorophenol from 2,4,5-T has been...
