Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Readily biodegradable: 79% (CO2 evolution) after 28 d (OECD 301B)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One study investigating the ready biodegradability of fatty acids, lanolin, esters with pentaerythritol (CAS 68440-09-5) is available (Clarke, 2012). The GLP study was conducted under aerobic conditions according to OECD Guideline 301B using non-adapted activated sludge as inoculum. A test concentration of 12.9 mg/L based on test material was applied. Based on CO2 evolution a biodegradation of 79% was observed after 28 days.Since the substance reached the pass level for OECD 301B (biodegradation is > 60% after 28 d) the substance is stated to be 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.
