Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Additional information

VDF has an experimental log Kow of 1.24. This value indicates that possible bioaccumulation in the food chain is not significant. Based on its limited water solubility and the substance being a gas, it can be concluded that VDF will volatilize rapidly, and therefore partition nearly exclusively to air (>99%) and will not remain in the water. Significant contact with the organisms in the food chain can therefore considered to be negligible. This is supported by the BCF of 3.06 L/kg calculated with BCFBAFv3.00 (U.S. EPA, 2008)(see Annexes 7 and 8 for the QMRF and QPRF).
