Sodium Benzoate: Less Than 1/10th Of 1

Sodium benzoate is a salt of benzoic acid, a chemical that occurs naturally in some fruits. It is typically produced industrially by reacting toluene with chlorine and then oxidizing the resulting benzyl chloride. It appears as a white crystalline powder.

Sodium benzoate is primarily used as a preservative in packaged foods. It helps prevent the growth of mold, yeast, and bacteria, extending the shelf life of products. It is commonly found in acidic foods like salad dressings, carbonated drinks, jams, and pickles.

In the U.S., sodium benzoate is Generally Recognized As Safe (GRAS) by the FDA when used according to good manufacturing practices. When combined with ascorbic acid (Vitamin C) in beverages, it can form small amounts of benzene, a known carcinogen. However, levels are typically very low and the FDA has stated that the risk is low. JECFA and EFSA have also evaluated sodium benzoate and established acceptable daily intakes.
