Methyltriclosan is a metabolic product of the biocide and bacteria inhibitor triclosan .

Occurrence

Methyltriclosan is formed from triclosan in wastewater on its way to and in the sewage treatment plant . Since it is not completely eliminated in the sewage treatment plant, it ends up in the surface waters. The half-life of methyltriclosan is longer than that of triclosan and it is less rapidly broken down. It can therefore be detected in water.

use

Methyltriclosan is not used. The occurrence in wastewater and in the environment comes about through metabolism , precisely through methylation of Triclosan.
