potassium persulphate

Main Applications: Polymerization (similarly used as a free-radical initiator in emulsion polymerization for plastics, rubber, and resins), Hair Bleaching (a common component in hair bleach formulations as an oxidizer, often in combination with ammonium persulfate), Printed Circuit Board Etching (etchant for microelectronics to selectively remove metals) and Pool & Water Treatment (used in some applications to generate free radicals for oxidative cleaning). Potassium persulfate is valued for its stability and is often the persulfate of choice in cosmetic bleach powders.
