Description & Application
Sodium benzoate is a slightly hygroscopic, white, odorless or nearly odorless crystalline powder or granular, soluble in water, ethyl alcohol, insoluble in ethyl ether.

Sodium benzoate is a well-known and widely used preservative for pharmaceutical products such as syrups, flavored vehicles, and multiple dose containers for liquid preparations. For Industrial applications, sodium benzoate has found considerable application as a corrosion inhibitor in low concentrations and reduces fouling by reducing the tendency of rust and scale to dislodge from corroded surfaces.
