Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 91.8 % 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 1,3-Propanediol, 2,2-dimethyl-, C5-9 carboxylates (CAS 85711-80-4) is available (van Dievoet, 1998). The study was performed following the OECD Guideline 301 B. Activated sludge from the aeration tank of a municipal wastewater treatment plant was used as inoculum. Passing of the 10 -day window is not clearly reported in the report. However, during the 28-day test period, biodegradation reached 91.8%, based on CO2 evolution. Thus the substance is regarded as readily biodegradable, but failing 10 -day window.
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.
