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

log Pow = -3.57 to -1.55

Key value for chemical safety assessment

Additional information

The partition coefficient of the substance was determined mainly by QSAR calculation with KOWWIN (v1.68) for the single components. For the main components a partition coefficient of log Pow= - 3.57 (closed form of isomaltulose, CAS 13718-94-0, and closed form trehalulose, CAS 51411-23-5) was determined. The highest partition coefficient (log Pow = -1.55) was determined for fructose (CAS 57-48-7).
