Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Biodegradation in water: screening tests

Description of key information
The key study for biodegradability (Hanstveit, 2003) reported 0% degradation of the registered substance after 28 days and -3% after 39 days. The substance is therefore not considered readily biodegradable as the 60% degradation criterion after 28 days was not met. The oxygen consumption in the degradation test was inhibited by the test substance. Therefore, any biodegradability of tetraoctylstannane could not be demonstrated in this test due to its inhibiting effects to the inoculum.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
A reliability rating of 1 was assigned to the key study, according to the criteria of Klimisch, 1997 as the study was conducted in accordance with recognised guidelines and GLP.
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.
