Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The water solubility of potassium allophonate was tested according to Organisation for Economic Co-Operation and Development (OECD) Test Guideline 105. When testing a series of test solutions with serially increasing concentrations of the test substance, the water solubility was found to be >30.03 %w/w and <39.98 %w/w (corresponding to >429,890 mg/L and <666,200 mg/L). In a separate test reported in the same study, a single test substance concentration of 33 %w/w was found to be initially soluble; however after overnight standing, excess test substance was clearly visible. Therefore, the results of the separate test are ultimately insoluble. Given that potassium allophonate is soluble at 30.03 %w/w (429,890 mg/L), potassium allophonate is considered to be very soluble (i.e., >10,000 mg/L).

Additional information
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.
