Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 62.9% (CO2 evolution) after 28 d (OECD 301B)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One guideline study investigating the ready biodegradability of Fatty acids, C6-18, triesters with trimethylolpropane (CAS 91050-88-3) is available. The biodegradation of the substance was tested in a CO2 Evolution Test according to OECD 301B using domestic activated sludge as inoculum. At test termination after 28 days the test substance was degraded by 62.9%, not fulfilling the 10-day window (Muckle, 2008). As the test substance is a mixture of constituents with different chain-lengths (UVCB), sequential (instead of concurrent) biodegradation takes place and the 10 -day-window should not be considered for this UVCB substance. Thus, the test substance is readily biodegradable according to 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.
