Description of key information
Additional information
Chlorotrifluoroethylene (CTFE) is a volatile gas at ambient condition with a moderate water solubility and an high tendency to rapidly volatilise to the air. This tendency is also confirmed by the results from the EQC Fugacity III Model (Version 2.02, The Canadian Centre for Environmental Modelling and Chemistry, May 2003). The Level III fugacity model predicts partitioning between four environmental compartments (air, soil, sediment and water) using a combination of default parameters and various input physico-chemical parameters. The model was run assuming emissions only to air. In fact, in case of an accidental emission, CTFE is uniquely released to air, because of its volatility at ambient conditions and boiling pointin the range of -26.2°C (The Beilstein database. Reference: Miller - 1951) to -26.8°C (The Beilstein database. Reference: Henne - 1948).
The environmental fate of the substance, assessed through the model, confirmed that, following emissions in air, CTFE remains in this compartment. The rates of transfer to soil and water are very low and only negligible amounts of the total emission remain in these media and in sediment.
Hence, due to the gaseous nature of the substance and its partition to the atmosphere, as well as the consequent difficulty to appropriately test CTFE and provide meaningful results, no experimental bioaccumulation data are reported. However, in order to evaluate the bioaccumulation hazard profile of CTFE despite the fact, that it is expected to rapidly partition to the atmospheric compartment, the BCFBAF (v.3.00, EPI Suite v.4.0) model may be applied, the result of the BCFBAF model is attached.
The model prediction for CTFE yielded a BCF of 5.7 and a log Kowof 1.65.
According to Annex XIII of Regulation (EC) No 1907/2006 and to the Guidance on information requirements and chemical safety assessment Chapter R.11 (PBT Assessment, May 2008), a substance does not fulfill the criterion “bioaccumulative (B)” or “very bioaccumulative (vB) ” if the BCF is below 2000 and 5000, respectively, or the log Kow is below 4.5, therefore CTFE is not expected to be bioaccumulative.
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).
