Measured properties

Appearance: Sodium nitrate appears as a white crystalline solid. Noncombustible but accelerates the burning of combustible materials. If large quantities are involved in fire or the combustible material is finely divided an explosion may result. May explode under prolonged exposure to heat or fire. Toxic oxides of nitrogen are produced in fires. Used in solid propellants, explosives, fertilizers, and for many · Dry Powder, Large Crystals, Liquid, Other Solid, CBI

Irritation and sensitisation studies

3 skin studies and 3 eye studies are on record.

Classed as low2

The study conclusions largely agree (100%). These tests are on the raw material itself; irritation at the amount in a finished product is a different question.
