Sodium benzoate, also known as sodium benzoate, is a kind of organic matter, chemical formula C7H5NaO2, is a white granular or crystalline powder, odorless or with a benzoin odor, slightly sweet taste, convergence taste, relative molecular weight of 144.12, stable in air, soluble in water, its aqueous solution pH value is 8, soluble in ethanol.
Benzoic acid and its salts are broad spectrum antimicrobial agents, but their antibacterial effectiveness depends on the pH value of the food. With the increase of acidity of the medium, its bactericidal and bacteriostatic effect is enhanced, while in alkaline medium, it loses bactericidal and bacteriostatic effect. The optimum pH value of its anticorrosion is 2.5~4.0.
The effects of sodium benzoate are as follows：
1, mainly used as food preservatives, but also used to make drugs, dyes, etc
2, used in pharmaceutical industry and plant genetic research, also used as dye intermediates, fungicides and preservatives
3. Preservatives; Antimicrobial agents.
4, sodium benzoate is also an important acid food preservative. When used, it is converted to the effective form benzoic acid. See benzoic acid for scope of use and usage. In addition, it can also be used as a preservative of feed.
5, the product is used as a food additive (preservative), fungicide in the pharmaceutical industry, mordant in the dye industry, plasticizer in the plastic industry, and also as an intermediate in the organic synthesis of spices.
6. Used as a co-solvent for serum bilirubin test, food additive (preservative), fungicide for the pharmaceutical industry, mordant for the dye industry, plasticizer for the plastic industry, and also used as intermediates in the organic synthesis of spices and so on.

Sodium benzoate is divided into powder and granular forms.
