Description of key information

The estimated soil adsorption coefficient (Koc) of difluoroacetic acid was found to be 2.252. This value when calculated at 20 deg C works out to be 1.8016.

Key value for chemical safety assessment

Additional information

Soil Adsorption Coefficient i.e Koc value of difluoroacetic acid was estimated as 2.252 by means of MCI method ( EPI suite ). This indicates that difluoroacetic acid shows negligible sorption to soil and sediment and rapid migration potential to groundwater. This value when calculated at 20 deg C was found to be 1.8016.
