Sodium Benzoate And EDTA

Sodium benzoate is a salt of benzoic acid, a widely occurring natural compound. It is typically manufactured synthetically by reacting toluene with chlorine, followed by hydrolysis and neutralization. EDTA (ethylenediaminetetraacetic acid) is a synthetic compound used as a chelating agent.

Sodium benzoate and EDTA are often used together as preservatives. Sodium benzoate inhibits the growth of mold, yeast, and some bacteria, while EDTA helps to stabilize products by binding to metal ions that can cause spoilage. They are commonly found in acidic foods and beverages like soft drinks, fruit juices, and pickles.

In the US, sodium benzoate is Generally Recognized As Safe (GRAS) by the FDA when used according to good manufacturing practices. EDTA is also approved by the FDA for use in food. Regulatory bodies like JECFA and EFSA have evaluated these substances. Some studies have explored potential links between sodium benzoate and hyperactivity in children, though evidence is mixed and regulatory bodies have not established a causal link at typical intake levels. Concerns have also been raised about the potential formation of benzene, a carcinogen, when sodium benzoate is combined with ascorbic acid (Vitamin C) in certain conditions, leading to product reformulation.
