Potassium persulfate (K2S2O8), also know as KPS, is a chemical compound. It is a food additive and it is used in organic chemistry as an oxidizing agent for instance in the Elbs persulfate oxidation. It takes also an important role as initiator for emulsion polymerization.

Conditions/substances to avoid are: heat, flames, ignition sources, powdered metals, phosphorus, hydrides, organic matter, halogens, acids and alkalis.
