Product of methylation of triclosan

Methyl-triclosan is a transformation product of the biocide triclosan. Triclosan is widely used, for instance in disinfectants, soaps, and deodorants, as preservative in cosmetic products and as antibacterial treatment of textiles.

Methylation of triclosan in sewage treatment plants (STP) may result in the formation of methyl-triclosan which partly enters surface waters via the STP-effluents. Methyl-triclosan is assessed as persistent in the environment and toxic to aquatic organisms. Because of its lipophilicy it can accumulate in organisms.
