Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The only biodegradability study available for dimethyltin dichloride (DMTC) was a ready biodegradradability study conducted to OECD Guideline 301F using oxygen consumption as the test criterion. The test substance was added to the test medium by means of a stock solution in ultrapure water. A single concentration of 111 mg/l was tested, corresponding to a ThODNH3of 56.6 mg O2/l. An inoculum was prepared from activated sludge taken from an oxidation ditch used to treat domestic sewage.The test was extended to 35 days, because the plateau phase had not been reached after 28 days of incubation. DMTC was found not to be degraded. Consequently, the 60% degradation criterion was not met and therefore it was considered not readily biodegradable in this test.
Further biotic degradation tests were considered unnecessary. The substance was considered to be of no immediate concern to the environment and the available data were found to be adequate for classification and labelling purposes and PBT assessment. Appropriate adaptations from the standard data requirements were submitted to address the higher tier the individual endpoints.
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.
