Description of key information
In accordance with column 2 of REACH (REGULATION (EC) No 1907/2006) Annex VIII the study on toxicity to microorganisms (required in section 9.1.4) does not need to be conducted as the emission to the sewage test plant is considered negligible.
The substance is a volatile gas at ambient conditions which is expected to primarily and rapidly partition to atmosphere based on its boiling point in the range of -26.2°C (The Beilstein database. Reference: Miller - 1951 ) to -26.8°C (The Beilstein database. Reference: Henne - 1948) a vapour pressure of 612 kPa at 25°C (ISCS No. 0685, NIOSH) and a moderate solubility of 380 mg/L in water (the water solubility value of 380 mg/l has been evaluated in a closed system with the atmosphere saturated of CTFE hence it represents an overestimation of the actual water solubility of CTFE in the natural system).

Additional information
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.
