Description of key information
Performance of a test for adsorption/desorption was waived, based on physical chemical properties and hydrolysis behaviour of persulfates. Substances of the Persulfate Category are very soluble in water and present ionic form. The persulfate anion degrades to oxygen and sulphur as well as hydrogen ions. After decomposition products are ubiquitous to the environment.
Key value for chemical safety assessment
Additional information
In accordance with Column 2 of REACH Annex IX adsorption/desorption testing, information requirement 9.3.3, can be waived based on the physicochemical properties and hydrolysis behaviour. Persulfates are soluble in water and their vapour pressures are negligible. Thus, persulfates released into the environment are distributed into the water compartment in the ionic form of the cation and persulfate ion. The persulfate anion readily oxydises water to oxygen producing sulphate and hydrogen ions. Persulfates are not expected to sorb to soil due to their dissociation properties, instability (hydrolysis) and high water solubility. All persulfate degradation products are ubiquitous to the environment.
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.
