Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Performance of a test for bioaccumulation in aquatic species was waived. Substances of the Persulfate Category are inorganic salts sharing the same anionic persulfate moiety. Persulfates are very soluble in water and are not expected to bioaccumulate in soil or aqueous solutions. They will decompose into organic sulfate or bisulfate. 

Key value for chemical safety assessment

Additional information

In accordance with Column 2 of REACH Annex IX, bioaccumulation in aquatic organisms, information requirement 9.3.2, can be waived if the substance has a low potential for bioaccumulation and direct and indirect exposure to the aquatic compartment is unlikely. Substances of the Persulfate Category are inorganic salts sharing the same anionic persulfate moiety. Persulfates are very soluble in water and are not expected to bioaccumulate in soil or aqueous solutions. They will decompose into organic sulfate or bisulfate. Experimental determination of a log Pow was waived, instead a default log Pow of -1 was assumed for risk assessment (EUSES v 2.1 default). Based on the low potential for bioaccumulation, experimental determination of the bioaccumulation factor (BCF) was waived.
