Preserved With Less Than 1% Sodium Benzoate

Sodium benzoate is a salt of benzoic acid, a chemical that occurs naturally in small amounts in fruits like cranberries and plums. It is typically produced industrially by reacting toluene with chlorine, then hydrolyzing the resulting benzotrichloride. It is commonly used in its powdered form.

Sodium benzoate is a preservative that prevents the growth of mold, yeast, and bacteria in foods and beverages. It is most effective in acidic conditions, which is why it is frequently found in acidic foods like sodas, fruit juices, pickles, and salad dressings.

The FDA considers sodium benzoate Generally Recognized As Safe (GRAS) when used according to good manufacturing practices. JECFA has evaluated it and set an acceptable daily intake. In combination with ascorbic acid (Vitamin C) and under certain conditions, sodium benzoate can form small amounts of benzene, a known carcinogen. However, the FDA states that the levels of benzene formed are very low and not a concern for human health. Some studies suggest a possible link between sodium benzoate and hyperactivity in children, but the evidence is mixed and not conclusive.
