Description of key information
Ready Biodegradability (CO2 Evolution Test, OECD Guideline 301 B): not readily biodegradable but inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
The test substance was not readily biodegradable. The biodegradation was 54 % within 28 days and 31 % within the 10d window.
The test substance is assumed to be inherently biodegradable, as it just missed the threshold of 60 % degradation within 28 days. The ECHA Guidance on Data Requirement and CSA, Part 7b says: "When results of ready biodegradability tests indicate that the pass level criterion is almost fulfilled (i.e. ThOD or DOC slightly below 60% or 70% respectively) such results can be used to prove inherent biodegradability."
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
