Description of key information
Additional information
TMQ is not readily and inherently biodegradable. No biodegradation of TMQ was ob-served during 28 days exposure in a closed bottle test according to EU method C.4-E (Bayer AG, 2000) and during 35 days exposure to adapted bacterial inoculum (Monsanto, 1979). Therefore better biodegradability in simulation test is not expected and it is scientifically unjustified to carry out such tests. TMQ is considered as provisionally persistent in surface water, sediment and soil.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
