Sodium benzoate, also known as benzoic acid sodium salt, is a classic acidic preservative appearing as white granules or crystalline powder, odorless or slightly fragrant with a balsamic scent, and highly soluble in water. It is internationally recognized as a low-toxicity preservative and is classified by the U.S. FDA as Generally Recognized as Safe (GRAS), with the European Union food additive code E211. The antimicrobial effectiveness of sodium benzoate strongly depends on the pH of the medium: in acidic environments (optimal pH 2.5–4.0), its lipophilic molecules easily penetrate microbial cell membranes, disrupt membrane permeability, and inhibit respiratory enzyme activity, thereby exerting preservative effects; however, it is nearly ineffective under alkaline conditions. Due to its high efficiency and low cost, sodium benzoate is widely used in food, pharmaceuticals, personal care products, and various industrial applications.
Application:
1. Food and Beverage Industry
Sodium benzoate is one of the most widely used preservatives in the food industry, primarily employed to inhibit the growth of yeast, mold, and certain bacteria.
Seasonings and sauces: widely used in soy sauce, vinegar, pastes and paste products, composite seasonings (such as salad dressings and flavoring sauces), oyster sauce, fish sauce, etc., to prevent mold growth after opening. The maximum usage level in vinegar, soy sauce, and fermented sauces is 1.0 g/kg.
Beverages: Used in acidic beverages such as carbonated drinks, fruit and vegetable juice drinks, protein drinks, tea beverages, flavored drinks, and specialty beverages to prevent microbial contamination. The maximum allowable level is 0.2 g/kg in carbonated drinks and 1.0 g/kg in fruit and vegetable juice drinks.
Candied fruits and jams: Used in candied fruits, preserved fruits, jams, and similar products to prevent mold growth and extend shelf life. The maximum usage level is 0.5 g/kg for candied fruits and 1.0 g/kg for jams.
Pickled vegetables and confectionery: maximum usage level is 1.0 g/kg for pickled vegetables; 1.5 g/kg for chewing gum, and 0.8 g/kg for other confectionery.
Baked goods and flavored syrups: Used in packaging cakes, pies, and other baked products as well as flavored syrups to prevent microbial spoilage.
II. Pharmaceuticals and Drug Formulations
Sodium benzoate is primarily used in the pharmaceutical field as a preservative and solubilizing agent.
Pharmaceutical preservation: Used in liquid formulations such as syrups, oral liquids, and eye drops to prevent microbial contamination and ensure drug stability. Common concentration ranges from 0.1% to 0.2%.
Solubilizing agents: Form complex salts with compounds such as caffeine and theobromine, thereby increasing drug solubility. Sodium benzoate caffeine is an example that utilizes this principle.
III. Cosmetics and Personal Care Products
Sodium benzoate is used as a mild preservative in cosmetics and personal care products.
Skincare and personal care products: Used in toners, lotions, facial cleansers, shampoos, and similar products to prevent bacterial and fungal growth, ensuring product hygiene.
Oral care products and toothpaste: used in toothpastes and mouthwashes to protect the product from microbial contamination.
4. Industry and Other Fields
Feed preservation: Used as a mold inhibitor for poultry and livestock feed to prevent spoilage during storage.
Automotive chemicals and oil extraction: used as a corrosion inhibitor in antifreeze; acts as an anti-fermentation agent in offshore drilling fluids to prevent the fermentation and degradation of starch-based treatment agents.
Metal corrosion inhibition and dyeing: acts as a rust and corrosion inhibitor in automotive cooling systems; used as a mordant in the textile dyeing industry.
