Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 76- 80% (CO2 evolution) after 28 d (OECD 301B)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Two studies, investigating the ready biodegradability of fatty acids, C16-18 even numbered and C18-unsatd. triesters with propylidynetrimethanol (CAS 57675-44-2) according to OECD 301B (CO2 Evolution Test), are available. In the key study (GLP; Häner, 2007) domestic activated sludge (non adapted) and in the supporting study (King, 1994) secondary effluent was used as inoculum. Häner (2007) observed a mean degradation of 80% whereas the biodegradation in the second study was measured to be 76% after 28 days (King, 1994). In both studies the 10-day-window was fulfilled. Therefore, the test substance can be classified as readily biodegradable according to OECD criteria.
Furthermore the numerous further studies are available for the polyol esters which cover the variability of members with different alcohol and fatty acid chain lengths all confirm that the polyol ester category members are readily biodegradable ( please refer to IUCLID section 5 and the category justification in section 13).
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.
