Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
According to Reach Annex XI section 1, a study is scientifically unjustified. A biodegradation test should provide data on biodegradation under specified environmentally relevant conditions. The study Bayer (1992) which is performed as a ready test is considered as similar to an inherent study as the relation amount of bacteria / test substance was higher. As no biodegradation (0%) was observed in a study on ready biodegradability is not expected that a significant degradation would occur in a simulation test. The test substance is considered as non-biodegradable in surface water and sediment compartment. Moreover, biodegradation is irrelevant as primary degradation step because immediate hydrolysis takes place. No additional information would be obtained through that test.

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.
