Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Potassium iodide is very stable under ordinary conditions of use and storage. The phototransformation in air is irrelevant to potassium iodide, because few potassium iodide can be distributed in air for the low vapour pressure and high water solubility.
Hydrolysis is not a concern to such inorganic substance which can be completely ionized in water phase. Potassium iodide will completely dissociate in water giving potassium ion and iodide anion.
The potassium iodide is readily absorbed by organisms as K+ and I-, which are both small (an)ions and well known not likely to be bioaccumulated.
Based on the intrinsic prosperities of potassium iodide, the substance can be expected to have a low potential for adsorption (completely ionized to small ions in water phase). The potassium ion and iodide anion are uniformly distributed in water phase. In the air, these two basic (an)ions is negligible, due to high water solubility and low vapour pressure. To sediment and soil phases, these two (an)ions are mostly distributed in the pore water.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.
