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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Abiotic degradation:
Sulfamic acid is an inorganic substance, which is stable in the environment. It can be ultimately hydrolysed into ammonium hydrogen sulphate (NH4HSO4) in the environment, which is not classified as hazardous to the aquatic environment in Regulation EC No 1272/2008, but the half-life would be very long. Therefore, the hydrolysis can be ignored at ambient temperature. Considering the structure of the sulfamic acid, it is not likely to be photolyzed in the environment.
Biodegradation:
As the substance is inorganic, the biodegradation is not relevant to sulfamic acid.
Transport and distribution
Sulfamic acid, having a low vapour pressure (0.78 Pa), high water solubility, and non-adsorptive substance, is not inclined to be distributed or transported to the atmosphere, and is not expected to end up in soil via atmospheric deposition.
Sulfamic acid will is expected to remain in the water phase neutralized to sulfamates.
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.
