Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Administrative data
Link to relevant study record(s)
Description of key information
Not readily biodegradable according to OECD criteria. Poorly biodegradable. Poorly eliminated from water.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The biodegradability of the test substance (respectively its hydrolysis products, since the substance hydrolyses rapidly in contact with water) was investigated in several guideline studies. The ready biodegradability was tested in a guideline study according to OECD 301C (conducted by japanese authorities) as well as in a study according to OECD 301E (BASF AG 93/0156/20/1, 1993). The studies revealed degradation values of 0 - 16% and 0% after an exposure duration of 28 days, respectively. In an inherent biodegradability study according to OECD 302B no DOC removal was detectable after 28 days of exposure. Based on these data, the test substance is considered to be poorly biodegradable and poorly eliminated from water.
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.
