Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
MBTS is not readily biodegradable with a biodegradability of 0% observed in 28 days (Bayer AG, 1988). The potential metabolites of MBTS are also not readily biodegradable and only certain level of degradation was observed for MBT, BT, BTon and MeSBT when the microorganisms used adapted under special conditions. Such processes are expected in biological treatment plant, but not in the environment.
According to the negligible biodegradation of MBTS and its potential metabolites, no better biodegradability can be expected to be observed in simulation test and hence to carry out such tests are scientifically unjustified. MBTS and its potential metabolites are expected to be non-biodegradable and hence 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.
