Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No data available.
The requirement for sediment toxicity data has been waived on the basis that further testing to sediment organisms is not necessary according to the chemical safety assessment. Potassium formate is readily biodegradable, is not expected to adsorb to solid soil phase (log Koc < 3) and does not accumulate significantly in organisms (log Kow < 3). Results from the pelagic studies indicate that potassium formate is acutely not harmful. A long-term study with D. magna revealed no chronic toxicity. The equilibrium partitioning method can be used to assess the hazard for sediment organisms and further sediment toxicity studies are scientifically unjustified.
Key value for chemical safety assessment
Additional information
In accordance with column 2 of REACH Annex X, the long-term toxicity testing to sediment organisms shall be proposed depending on the results of the chemical safety assessment. Potassium formate is readily biodegradable, is not expected to adsorb to solid soil phase (log Koc < 3) and does not accumulate significantly in organisms (log Kow < 3). Results from the pelagic studies indicate that potassium formate is acutely not harmful. A long-term study with D. magna revealed no chronic toxicity. The equilibrium partitioning method can be used to assess the hazard for sediment organisms.
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.
