Administrative data
Link to relevant study record(s)
Description of key information
OECD Guideline 301D, GLP, key study, validity 1:
50% biodegradation after 28 days and 67% biodegradation after 60 days (enhanced biodegradability testing).
Not readily biodegradable but ultimately and inherently biodegradable.
Not persistent.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, fulfilling specific criteria
Additional information
One valid key study is available to assess the biodegradation potential of the registered substance. This study was performed according to OECD Guideline 301D with GLP statement. The substance was exposed to activated sewage sludge micro-organisms at a concentration of 1 mg/L with culture medium in closed bottles in the dark at 22-24 °C for 7, 14, 21, 28, 42 and 60 days. The degradation of the substance was assessed by the measurement of oxygen consumption.
The test substance was biodegraded by 50% at day 28 and by 67% at day 60 (enhanced biodegradability testing). This result demonstrates that the registered substance is not readily biodegradable but ultimately and inherently biodegradable. Moreover, biodegradation percentages of >60 within a 60-day time period allows classification of the test substance as not persistent.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.
