Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Not readily biodegradable: -10% (DOC) of PF-6 after 28 d (OECD 301A)
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The biodegradation of PF-6 (CAS 61358-25-6) under aerobic conditions was investigated in a GLP guideline study. The test was performed according to OECD 301A (Eisner, 2012).
In the test flasks, containing the test item and activated sludge (inoculum), the mean concentration of DOC (dissolved organic carbon) varied between 23 and 27 mg/L over the exposure period of 28 days and thus was not significantly different from the initial mean DOC concentration of 24 mg/L measured on Day 0. Expressed as percentage DOC removal, mean values in the range from 7 to -10% were noted. Therefore, PF-6 was not biodegradable under the test conditions.
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.
