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


Dissociates in water to calcium ion and formate ions. Both of these are considered stable in water. 

A carboxylic acid is generally the final product of hydrolysis reactions (Lyman, 1990).

In accordance with column 2 of REACH Annex VII, the study does not need to be performed if the substance is readily biodegradable. The analogous substance sodium formate is readily biodegradable (KM Lab, 1998).



Calcium diformate is readily biodegradable according to a read-across approach to sodium formate (OECD 306; KM Lab, 1998).

According to the REACH Guidance, when a chemical attains more than 60% ThOD or more than 70% DOC removal in a Biodegradability in Seawater test (OECD 306), it can also be expected to fulfil the criteria for ready biodegradability. Therefore, sodium formate and hence calcium diformate are regarded as readily biodegradable (KM Lab, 1998).



In accordance with column 2 of Annex IX, the study does not need to be conducted if the 1-octanol/water partition coefficient is <3. Due to the low logPow of below -1.8 (Na formate; Perstorp, 2009), accumulation in organisms is not expected. Thus, and for reasons of animal welfare, no study on bioaccumulation in fish is performed.


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 ofKoc = 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).
