Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 82% (CO2 evolution) after 28 d (OECD 301B)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
One GLP Guideline Study according to OECD 301B is available investigating the ready biodegradability of 1,3-butylene diacetate (CAS 1117-31-3) (Roulstone, 2012). Non-adapted activated sludge from a domestic sewage treatment plant was used as inoculum. The test substance, which was applied at a concentration of 18.1 mg/L was degraded to an extent of 82% (CO2 evolution) after 28 d fulfilling the 10 day window. Since the substance reached the pass level for OECD 301B (biodegradation is > 60% within 10-day window) 1,3-butylene diacetate 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.
