Potassium benzoate Uses

Potassium benzoate (CAS NO.582-25-2) is a food preservative that inhibits the growth of mold, yeast and some bacteria. It works best in low-pH products, below 4.5, where it exists as benzoic acid. Potassium benzoate is also used as the whistle in many fireworks.

Potassium benzoate Production

Methods:1
By potassium bicarbonate solution and acid derived.
Methods:2
Remand from the bicarbonate solution and benzoic acid derived.

Potassium benzoate Safety Profile

Combustible when exposed to heat or flame. When heated to decomposition it emits acrid smoke and irritating fumes.
Safety Information of Potassium benzoate (CAS NO.582-25-2):
Safety Statements: 22-24/25
S22:Do not breathe dust.
S24/25:Avoid contact with skin and eyes.
