Description

Potassium persulfate is the inorganic compound with the formula K2S2O8. Also known as potassium peroxydisulfate or KPS, it is a white solid that is highly soluble in water. This salt is a powerful oxidant. Potassium persulfate is used as an initiator for emulsion polymerization reactions, in the preparation of acrylic, vinyl, styrene, neoprene, styrene-butadiene and other resins. It is also used in depolymerization in modification of starch, as a booster in hair bleaching formulations in cosmetics and as a gel breaker in oil recovery systems.
