Potassium Persulphate – K₂S₂O₈

EC No: 231-781-8
CAS No: 7727-21-1
EC name: dipotassium peroxodisulphate
IUPAC name: dipotassium peroxodisulphate
Trade name: Potassium Persulphate
Synonyms: Potassium Peroxodisulphate, Dipotassium Peroxodisulphate, Anthion, Potassium persulfuricum
Physical appearance: white crystals

Potassium Persulphate is an odourless, white, crystalline salt with only a minor hygroscopic character.
Due to its fine crystalline form, it has a tendency for lump formation.
Therefore an optional delivery with silicic acid is possible. (0,5 %)
It is a strong oxidizer that is used in many applications.
Additionally, due to its high purity it has good storage stability and as well as it can be easily and safely handled.
It is not flammable but highly oxidizing.
