Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Not readily biodegradable: 29% (CO2 evolution) after 60 d (OECD 301B)
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
The ready biodegradability of fatty acids, C5-10, esters with dipentaerythritol (CAS 70983-72-1) was investigated according to OECD 301B (Muckle, 2012). Activated sludge from a wastewater treatment plant was used as inoculum. Microorganisms were exposed to a test substance concentration of 29.05 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 29%. 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.
