Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Activated sludge respiration inhibition testing on Ethaneperoxoic acid, reaction products with 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl thiocyanate and 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl thiocyanate: 3h EC50 >100 mg/L (highest concentration tested; read across substance);
Aerobic biotransformation in activated sludge from WWTPs is less than 7% of initially dosed 6:2 Fluorotelomer sulfonate, potassium salt (read across substance), which was converted to various transformation products after 90 d.
Key value for chemical safety assessment
Additional information
No toxicity to microorganisms with the test substance is available. An OECD Guideline 209 study with Ethaneperoxoic acid, reaction products with 3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,10-heptadecafluorodecyl thiocyanate and 3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl thiocyanate was used as a read across to fulfill the data gap for the test substance.
The underlying hypothesis supporting read-across includes the following: Additional documentation, provided within the IUCLID Assessment Reports section, supports the read-across approach.
The test substance had no significant inhibitory effect on the respiration rate of activated sludge at any of the concentrations employed in the test. The 3-hour EC50 was >100 mg/L.
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.
