Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

explosive properties of explosives
Type of information:
read-across based on grouping of substances (category approach)
Adequacy of study:
key study
Justification for type of information:
READ ACROSS CATEGORY APPROACH
A category group was formed with dipotassium peroxodisulphate (KPS), disodium peroxodisulphate (SPS) and diammonium peroxodisulphate (APS). Several physico-chemical, fate, ecotoxicological and toxicological endpoints were assessed using the category approach. Please refer to the read across justification in chapter 13 for further information.

Description of key information

For dipotassium persulfate, no study was available. However, company data on dust explosiveness revealed no such properties for the substance (see section 4.14: 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 physicochemical properties.

Key value for chemical safety assessment

Explosiveness:
non explosive

Additional information

For dipotassium 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, Study No. 89/02646, 1989) as this substance shows similar physicochemical properties. As diammonium persulfate was determined not explosive (Degussa, 1989), dipotassium persulfate was considered not explosive as well.

Justification for classification or non-classification

Assessment of explosive properties for dipotassium 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 as well as on experience in handling and use, dipotassium persulfate was not classified with respect to explosiveness when taking into account the provisions laid down in Regulation (EC) No 1272/2008, as amended for the fifteenth time in Regulation (EU) 2020/1182.
