Description of key information

Adsorption / desorption:

In accordance with column 2 of REACH Annex VIII, the study does not need to be conducted since sodium formate is readily biodegradable (KM Lab, 1998) and has a low potential for adsorption due to high water solubility coupled with a very low octanol-water partition coefficient (log Kow = -4.27; US EPA, 2006).

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:

The Henry's Law Constant (HLC) of the analogue substance formic acid was determined to be 0.019 Pa m³/mol at 25 °C (Khan & Brimblecomb, 1992).

Distribution modelling:

Over time, the substance will preferentially distribute into the compartment water.
