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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
TFSIH is not considered to be inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
No degradation studies are available for TFSIH. Therefore, information from the structural analog TFSILi was used to evaluate the possible degradation of TFSIH.
Justification for read-accross: TFSILi is salt of TFSIH, so the basis chemical structure is the same.
Regarding physico-chemical properties both products show the same range of data: high water solubility, log kow, low vapour presure . . .

OTHER PROPERTIES (if relevant for this endpoint)
- Adsorption characteristics: low potential of adsorption based on log kow
- Toxicity to aquatic organisms: Not harmful to daphnids and algae
Finally, toxicity on aquatic organisms is the same. Both products are not harmful to daphnids and algae.
There is adequacy assessment for the regulatory purposes of REACH.
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.
