Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
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
Additional information
In accordance with Annex VIII, column 2 the study does not need to be conducted if based on physicochemical properties the substance can be expected to have a low potential for adsorption (i.e. low Log P) or if the substance and its relevant degradation products decompose. Strictly speaking, this data requirement cannot be waived on this basis. However, potassium hydrogen difluoride fully dissociates into its constituent ions in aqueous environments (K+, H+ and F- ions will be formed in aqueous environments) and the dissociated species can be expected to have a low potential for adsorption and therefore further data is not required.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
