Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Substances of the Persulfate Category are inorganic salts sharing the same persulfate anion moiety. Performance of a test for adsorption/desorption was waived, based on physical chemical properties and hydrolysis behaviour of diammonium persulfate. Persulfates are soluble in water and their vapour pressures are negligible. Thus, persulfates released into the environment are distributed into the water compartment in ionic form of the cation and persulfate ion. Persulfates are not expected to sorb to soil due to their dissociation properties, instability (hydrolysis) and high water solubility. They behave as free ions and decompose into sulfate and bisulfate ions. All decomposition products are ubiquitous in the environment.
