1/10 Percent Sodium Benzoate

Sodium benzoate is a salt of benzoic acid, a chemical that occurs naturally in some fruits and spices. It is manufactured industrially by reacting toluene with chlorine to produce benzotrichloride, which is then hydrolyzed to benzoic acid. The benzoic acid is then neutralized with sodium hydroxide or sodium carbonate to form sodium benzoate.

Sodium benzoate is used as a preservative in many processed foods and beverages. It works by inhibiting the growth of bacteria, yeast, and mold, which helps extend the shelf life of products. It is commonly found in acidic foods like pickles, olives, relishes, salad dressings, and carbonated drinks.

In the United States, sodium benzoate is generally recognized as safe (GRAS) by the FDA when used as a food preservative. Regulatory bodies like JECFA and EFSA have evaluated sodium benzoate and established acceptable daily intake levels. Some studies have explored potential links between sodium benzoate and hyperactivity in children, particularly when combined with artificial colors, but the evidence is mixed and not conclusive.
