Barium stearate is in the form of white fine powder. The melting point is 160℃ and the relative density is 1.15. It is insoluble in water, insoluble in cold ethanol, soluble in hot ethanol, benzene, toluene and other non-polar solvents. It is water-absorbent in the air. It is heated and dissolved in organic solvents and turns into a gel after cooling. When encountering strong acid, it decomposes into stearic acid and the corresponding barium salt.

It is understood that barium stearate is toxic, with a toxicity coefficient of T=2. Acute toxicity: oral administration – rat LD50: 2506 mg/kg; oral administration – mouse LD50: 1832 mg/kg. Typical poisoning symptoms are vomiting, abdominal pain, diarrhea, increased blood pressure, pulse disorder, etc. High concentration or repeated exposure can cause weakness, paralysis of the limbs, heart and respiratory system.
