关于 Sodium Benzoate

Sodium Benzoate is the sodium salt of benzoic acid with the chemical formula C₇H₅NaO₂. It appears as a white, crystalline powder that is readily soluble in water. Sodium benzoate is produced by neutralizing benzoic acid with sodium hydroxide. It is widely used as a preservative due to its antimicrobial properties, particularly effective against yeasts, molds, and bacteria in acidic conditions.

Sodium Benzoate Uses

Food and Beverage Preservation

Sodium benzoate is extensively used as a preservative in acidic foods and beverages including soft drinks, fruit juices, pickles, salad dressings, and condiments. It inhibits the growth of yeasts, molds, and bacteria, extending shelf life and maintaining product safety. In carbonated beverages, sodium benzoate works synergistically with citric acid to provide effective preservation. It is also used in jams, jellies, and fruit preparations to prevent spoilage.

Personal Care and Pharmaceuticals

In cosmetics and personal care products, sodium benzoate serves as a preservative in shampoos, lotions, creams, and oral care products, preventing microbial contamination. The pharmaceutical industry uses it as a preservative in liquid medications, syrups, and topical formulations. Sodium benzoate also appears in some medications as an active ingredient for treating hyperammonemia and certain metabolic disorders.

Industrial Applications

Sodium benzoate is used in automotive antifreeze and coolant formulations as a corrosion inhibitor, protecting metal components from degradation. In metalworking, it serves as a rust inhibitor and corrosion preventative. The compound is also employed in fireworks manufacturing as a fuel component, and in chemical synthesis as an intermediate for producing various benzoate esters and other derivatives.
