Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
According to the read-across strategy document attached to this Chemical Safety Report (CSR), potassium allophonate quickly hydrolyses to urea in the environment. Therefore, read-across to urea is used to assess ecotoxicity. Potassium allophonate and its transformation product, urea, are of inherently low toxicity to fish species. Acute toxicity results on potassium allophonate did not indicate toxicity. Further, urea is rapidly assimilated into the nitrogen cycle by microorganisms, limiting exposure to aquatic organisms; therefore, testing of long-term toxicity to fish is scientifically unjustified.
Key value for chemical safety assessment
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.
