Description of key information

Adsorption/Desorption

Adsorption to solid soil phase is not expected.

In accordance with column 2 of REACH Annex VIII, the study does not need to be conducted since potassium formate is readily biodegradable (HRC, 1992) and has a low potential for adsorption due to high water solubility coupled with a very low octanol-water partition coefficient (log Kow <0, OSPAR, 2002).

Read across to formic acid reveals an adsorption rate for the formate ion ofKoc = 31 (log Koc = 1.49) (BASF SE, 2009).

 

Henry’s Law Constant

From the water surface, the substance will not evaporate into the atmosphere. The Henry's Law Constant (HLC) of the analogous compound formic acid was determined to be 0.019 Pa m³/mol at 25 °C (Khan & Brimblecomb, 1992).
