Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
Biodegradation in water: screening tests: Not readily biodegradable: 5% (DO) in 28 days (EU method C.4E)
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
There is a GLP study on ready biodegradation according to EU method C.4E on the registered substance itself available, which was classified as acceptable according to the guideline requirements. 12H-Dibenzo[d,g][1,3,2]dioxa-phosphocin, 4,8-dicyclohexyl-6-hydroxy-2,10-dimethyl- has to be classified as "Not Readily Biodegradable". No relevant deficiencies were noted which may lead to the conclusion that the present study may not be suitable to assess the substances biodegradability in the environment. Consequently, no datagaps were identified, the available study suffices to cover the present Biodegradation in water: screening tests endpoint.
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.
