Description of key information

Adsorption / desorption:

In accordance with column 2 of REACH Annex VIII, the study does not need to be conducted since calcium diformate is readily biodegradable (read across: Na formate; KM Lab, 1998) and has a low potential for adsorption due to a very low octanol-water partition coefficient (log Kow <-1.8; read across: Na formate; Perstorp, 2009).

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

Henry's law constant:

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).

Distribution modelling:

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