Description of key information

In accordance with column 2 of REACH Annex VII, the study on hydrolysis does not need to be performed if the substance is readily biodegradable. Potassium formate is readily biodegradable (HRC, 1992; NIVA, 2000).

Besides being readily biodegradable, potassium formate dissociates in water to potassium ion and formate ion.

Both of these are considered stable in water. A carboxylic acid is generally the final  product of hydrolysis reactions.

No testing is required because the material is a salt that is known to dissociate (hydrolyze) in water upon dissolution. Testing is considered impossible based on chemical principles as the anticipated concentration of undissociated material is near zero.
