Description
Potassium Persulfate is a white crystalline, odourless salt with the density of 2.477. It can be decomposed about 100 0C and dissolved in the water and has strong oxidation. It has the particular advantage of being almost non-hygroscopic of having a good storage stability in normal temperature and of being easy and safe to handle.

Storage
Potassium persulfate is not combustible, but assists combustion of combustible materials due to release of oxygen. It must be stored in a dry location away from heat and a cool, well ventilated area away from all sources of ignition and out of direct sunlight, protected from moisture.
Keep containers tightly closed, labeled and well sealed. Ensure pressure relief and adequate ventilation. It must be stored separately from organics, rust or traces of metal, reductions and others incompatible materials to avoid catalytic decomposition.
