Description of key information
Not readily biodegradable: 6% (CO2 evolution) after 60 d (OECD 301B)
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The ready biodegradability of 2,2-bis[[(1-oxoisononyl)oxy]methyl]-1,3-propanediyl diisononanoate (CAS 93803-89-5) was investigating according to OECD 301B (Muckle, 2012).Activated sludge from a wastewater treatment plant was used as inoculum.Activated sludge microorganisms were exposed to a test substance concentration of 28.95 mg/L (mean) under aerobic conditions for an extended duration of 60 d. The results indicated that the test substance reached a mean degradation of 6%. Therefore, the test substance is not readily biodegradable according to the OECD criteria.
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.
