Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

PBT assessment
Administrative data
PBT assessment: overall result
- PBT status:
- the substance is not PBT / vPvB
- Justification:
A hydrolysis study according OECD Guideline 111 with the main constituent 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl acrylate show a half-life for hydrolysis of 13.5 days at the temperature of 20 °C and pH 7. At pH 4 a half-life of 8.67 days and at pH 9 a half-life of 9.33 days is reported.
The photodegradation in the air for the degradation product 8:2 FTOH is reported with a lifetime of 11 d. An inherent biodegradation study according OECD 302B with the degradation product 8:2 FTOH show that there is a 100% elimination/degradation adable within 14 days (concentration at day 14 below LOD).
Therefore the ‘P’ criterion according to Annex XIII is NOT fulfilled for environmental compartments.
The ‘P’ criterion according to Annex XIII is NOT fulfilled for environmental compartments.
Butt et al. reported a rapidly biotransformation of 8:2 FTAC by the rainbow trout liver and stomach with formation of 8:2 FTOH. 8:2 FTAC was acccumulated in very low concentrations by the internal tissues of the dosed fish, suggesting that the 8:2 FTAc was rapidly biotransformed. similary, low concentrations of the 8:2 FTOH were accumulated in the fish tissues. A BCF of 83 – 310 is reported in a MITI test with 8:2 FTOH.
The ‘B’ criterion for the test item is NOT fulfilled.
All results from aquatic tests showed that the test item has no toxic effect to aquatic organisms.
The 'T' criterion for the test item is NOT fulfilled as the toxicity values are all above the toxicity criteria of 0.1 mg/L for the aquatic compartment.The substance is not classified as CMR or T, R48 or Xn,R48
For the test item the ‘PBT’ and 'vPvB' criteria are NOT fulfilled.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
