Sodium Benzoate
For Food, Feed, Pharmaceutical, Cosmetic, and Industrial Uses
Sodium Benzoate is the sodium salt of benzoic acid. One gram of salt is soluble in 2ml of water, in 75ml of ethyl alcohol, and in 50ml of 90% ethyl alcohol. The salt is insoluble in ethyl ether. A typical aqueous solution will be slightly alkaline and typically has a sweetish astringent taste. Sodium Benzoate is a slightly hydroscopic, white, odorless or nearly odorless product. Sodium Benzoate contains 84.7% of available benzoic acid.

Corrosion Inhibition
Sodium Benzoate is also used in industrial applications, including as a chemical intermediate, catalyst, nucleating agent for polypropylene manufacture, and as a corrosion inhibitor. Corrosion inhibitions has been reported at low concentrations for steel, zinc, copper, copper alloys, soldered joints, aluminum, and aluminum alloys, with the highest inhibition efficacy at PH levels 6-12.
Our Sodium Benzoate has outstanding physical properties for consistently high performance in all of handling, production, and packaging processes. Sinochem Supply Chain offers Sodium Benzoate in three forms for tailored performance and ease of use in a wide variety of applications: dust-free granules, anti-caking sprinkles, and easy-to-mix powder.
All forms are manufactured to meet National Formulary (NF), Food Chemicals Codex(FCC), European Pharmacopeia (EP), and EEC E-211 specifications.
