Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
On the grounds of the physico-chemical properties of CTFE and the results on environmental fate obtained from EQC Fugacity III Model (EQC Fugacity III Model, v.2.02, May 2003)
, the substance is expected to primarily and rapidly partition to the atmosphere. No exposure to the aquatic environment is consequently expected.Moreover, the Guidance on Information Requirements and Chemical Safety Assessment Chapter R.7a: Endpoint Specific Guidance, Appendix R.7.1-4 indicates that substances with a Henry's Law constant of around 1 hPa m3/mole rapidly volatilize from water.
The substance profile itself indicates the difficulty to properly test CTFE and provide meaningful results of its biodegradation in aqueous systems as well as in sediment and soil. Nevertheless a further assessment based on Quantitative Structure Activity Relationships (QSARs) has been however applied.
Particularly,in order to evaluate the biodegradation hazard profile of CTFE, the BIOWIN v.4.10, EPI Suite v.4.0 model has been applied.
The prediction of the BIOWIN model suggests that CTFE is not ready biodegradable.
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.
