Description of key information

Based on the results obtained from a  weight of evidence approach dipotassium persulfate was regarded oxidising.

Key value for chemical safety assessment

Oxidising properties:

Additional information

Dipotassium persulfate was not tested for oxidizing properties. A weight of evidence approach based on literature data and one secondary source was applied. The overall conclusion (oxidising solid) is thus regarded as reliable. Dipotassium persulfate was considered oxidising.

Justification for classification or non-classification

Based on the results obtained from a weight of evidence approach as well as on experience in handling and use, dipotassium persulfate was classified with respect to oxidising properties. Taking into account the provisions laid down in Regulation (EC) No 1272/2008, dipotassium persulfate was classified as oxidising solid Cat. 3 (may intensify fire; oxidizer). Respectively, the substance was classified as oxidizing (R8: contact with combustible material may cause fire) according to Directive 67/548/EEC (DSD).
