Potassium nitrate 99% purified [7757-79-1]
Potassium nitrate is used as a fertilizer, potassium nitrate is an oxidant. For this reason, its main application was the production of black powder, currently used in pyrotechnics as an oxidant. Potassium nitrate mixed with sugar or powdered sugar is the basic fuel component (oxidant) in self-made pyrotechnic materials, also used as a meat preservative (E252).

– the skull and crossbones, the exclamation mark pictogram should not be added.
– corrosivity, the pictogram exclamation mark should not be added if it concerns eye or skin irritation.
– health hazard determining respiratory sensitization, the exclamation mark pictogram should not be added if it concerns skin sensitization or irritation to eyes or skin.
