Description of key information

Not applicable. The hydrolysis data requirement has been waived on the basis that the substance is readily biodegradable. 

Key value for chemical safety assessment

Additional information

In accordance with column 2 of REACH Annex VII, the study 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.
