Description of key information

For disodium persulfate, no study was available. However, company data on dust explosiveness revealed no such properties for the substance (Support-001-Explosiveness.Degussa, 2001). This was used to support a read-across approach which was applied from the category member diammonium persulfate, as this substance shows similar physico-chemical properties.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

For disodium persulfate, no study was available. However, company data on dust explosiveness revealed no such properties for the test substance (Degussa, 2001). This was used to support a read-across approach which was applied to assess explosiveness using data from the category member diammonium persulfate (Degussa, 1989) as this substance shows similar physicochemical properties. As diammonium persulfate was determined not explosive, disodium persulfate was considered not explosive as well.

Justification for classification or non-classification

Assessment of explosive properties for disodium persulfate was based on company data and a read across approach from the category member diammonium persulfate, as this substance shows similar physicochemical properties. Based on the results obtained (not explosive, Key-001 and Support-001) as well as on experience in handling and use, disodium persulfate was not classified with respect to explosiveness when taking into account the provisions laid down in Regulation 1272/2008/EC (CLP), as amended for the fifteenth time in Regulation (EU) No 2020/1182.
