Ammonium Persulfate


Ammonium persulfate is a chemical compound with the molecular formula (NH4)2S2O8. It is a white, odourless, and water-soluble crystalline powder. Ammonium persulfate is a strong oxidizing agent and is commonly used as a radical initiator in various chemical reactions, such as polymerization, emulsion processes, and in the electronics industry for etching copper-coated printed circuit boards. Its high reactivity makes it valuable in many applications, including hair bleaching in the cosmetics industry and as a component in certain hair dyes. Additionally, it is used as an oxidizing agent in the preparation of various chemical compounds.


Ammonium persulfate exhibits potent oxidation and corrosion properties, readily decomposes under heat, has low moisture absorption capability, and is soluble in water. Its solubility increases further in warm water and other similar conditions.
