Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene (CAS 25291-17-2) is characterized by a water solubility of 1.21 mg/L (OECD 105), a vapour pressure of 4640 Pa at 25 °C (EpiSuite v4.11) and a log Koc of 2.65 (OECD 121). Thus, if the substance is released to the environment it will mainly partition to the atmospheric compartment due to high volatility. However, (Q)SAR results indicate that if released to the atmospheric compartment the substance will be degraded by reaction with OH-radicals. A DT50 < 19.26 h resulted. Significant adsorption to sediment and soil particles is expected to be low based on the low log Koc. Hydrolysis is not considered to be a relevant degradation pathway since the substance does not contain any chemical groups allowing hydrolysis in contact with water. The substance is considered to be hydrolytically stable in the environment. Significant biodegradation by activated sludge microorganisms is not expected. 0% degradation was recorded in a standard biodegradation study according to OECD 301C. Thus, the substance is not readily biodegradable according to the OECD criteria. Even though the substance is stable in the environment, bioaccumulation via aqueous exposure is considered to be low. An experimental study with fish according to OECD 305 (aqueous exposure) resulted in a low bioconcentration factor (BCF) of 300 - 380 (whole body wet weight, steady state).
