PBT assessment
Administrative data
PBT assessment: overall result
- Name:
- 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene - LE
- Type of composition:
- legal entity composition of the substance
- State / form:
- liquid
- Reference substance:
- 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene - LE
- PBT status:
- the substance is not PBT / vPvB
- Justification:
The PBT Assessment for 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene (CAS 25291-17-2) is based on the criteria set out in the “Guidance on information requirements and chemical safety assessment, Chapter R.11: PBT Assessment” (ECHA, 2017).
Persistence
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene is not readily biodegradable (0% after 28 days). Thus, the substance is considered to be vP/P.
Bioaccumulation
An experimental study according to OECD 305 resulted in a low potential for bioaccumulation. A BCF of 300 - 380 (whole body wet weight, steady state) was calculated. The BCF is clearly below the trigger value of 2000. Thus, 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene is not considered to be B/vB.
Toxicity
3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene is classified as STOT RE 1 (H372). Therefore, the substance meets the T criterion.
Conclusion
In conclusion, 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooct-1-ene is not considered to be PBT or vPvB.
Reference
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.
