Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Disodium persulfate was not tested for auto flammability properties. A read-across approach was applied for the test on auto flammability from the category member diammonium persulfate, as this substance shows similar physicochemical properties.

Key value for chemical safety assessment

Additional information

Disodium persulfate was not tested for auto flammability properties. A read-across approach was applied to assess auto flammability using data from the category member diammonium persulfate (section 4.12: Degussa, 1989) as this substance shows similar physicochemical properties. For diammonium persulfate no self-ignition was observed up to a maximum testing temperature of 600 °C. Furthermore, disodium persulfate was determined to decompose at a temperature of ca. 180 °C (section 4.2: Key-001-Melting point/melting range.Akkim, 2009). Thus, disodium persulfate is not expected to be auto flammable.
