Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 94% after 28 days (similar to ISO 10708)
Key value for chemical safety assessment
Additional information
One study investigating the ready biodegradability of Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] (CAS 91050-80-5) is available. This study (Hudson, 2007) is a marine Bodis-test similar to ISO 10708 performed under aerobic conditions using natural seawater as inoculum. A mean biodegradation of 94% was observed after 28 d. Biodegradation in seawater is expected to be slower than that in tests with freshwater and activated sludge as inoculum. Therefore, substances that reach the pass level in a seawater biodegradation test similar to ISO 10708 may be regarded as readily biodegradable. Thus, Fatty acids, C16-18, tetraesters with 3,3'-oxybis[1,2-propanediol] is stated to be readily biodegradable.
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.
