0.1% Sodium Benzoate

Sodium benzoate is a salt of benzoic acid, a chemical that occurs naturally in some fruits. It is typically manufactured by reacting toluene with chlorine and then oxidizing the resulting benzyl chloride. It is commonly used as a preservative in food and drinks.

Sodium benzoate is a preservative that inhibits the growth of bacteria, yeast, and mold. It is often found in acidic foods and beverages, such as pickles, relishes, salad dressings, carbonated drinks, and fruit juices, to help extend shelf life.

In the US, sodium benzoate is Generally Recognized As Safe (GRAS) by the FDA when used as a food preservative. It has been evaluated by international bodies like JECFA and EFSA. Some studies have explored its potential effects on hyperactivity in children, with mixed results and ongoing scientific discussion. When combined with ascorbic acid (Vitamin C) in beverages, it can form small amounts of benzene, a potential carcinogen, leading to efforts to minimize its formation.
