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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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: 82% (CO2 evolution) in 28 days (OECD 301 B)
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Ready biodegradability studies are available for isomaltulose (CAS 13718-94-0), trehalulose (CAS 51411-23-5) and palatinosesyrup (consists mainly of glucose, fructose and sucrose). The tests were conducted according to OECD Guideline 301 B and GLP (Lebertz, 2008). Activated sludge from a sewage treatment plant treating predominantly domestic sewage was used as inoculum. All tested substances turned out to be readily biodegradable, with 90%, 85% and 82% biodegradation after 28 days, for isomaltulose, trehalulose and palatinosesyrup respectively. Since the tested substances cover its main constituents, Reaction mass of 1-O-α-D-glucopyranosyl-D-fructose and 6-O-α-D-glucopyranosyl-D-fructose and fructose and glucose and sucrose can be considered 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.
