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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Hydrolysis:
All molecules of the reaction mass ionise under aqueous conditions in the environment to form potassium, aluminium and fluoride ions which will combine to form various inorganic salts and organic complexes. Since hydrolyses changes the chemical form but does not decompose , the concept of degradation by hydrolysis is not relevant in the consideration of its environmental fate.
Biodegradation:
The concept of biodegradation does not apply to inorganic substances.
Adsorption/desorption:
No significant sorption behaviour is to be expected for potassium cryolite as the substance dissociates into various ions. For fluoride a Koc value of 3.16 is calculated based on a log Kow of -1 in EUSES (in the EU-RAR for hydrogen fluoride a log Kow of -1.4 is suggested). From the data available for aluminium and potassium, no actual Kd and/or Koc values can be determined.
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.
