Polysorbate 80 And Sodium Benzoate

Polysorbate 80 is a synthetic emulsifier made from sorbitol (a sugar alcohol) and ethylene oxide. Sodium benzoate is a salt of benzoic acid, a naturally occurring organic compound found in many plants. It is produced industrially by reacting sodium hydroxide with benzoic acid.

Polysorbate 80 is used to help mix oil and water-based ingredients, preventing separation in foods like ice cream and baked goods. Sodium benzoate is a preservative that inhibits the growth of mold, yeast, and bacteria, commonly found in acidic foods such as pickles, olives, salad dressings, and carbonated beverages.

Both Polysorbate 80 and sodium benzoate are approved for use in the U.S. food supply by the FDA. Polysorbate 80 is generally recognized as safe (GRAS). Sodium benzoate is permitted as a preservative in food. JECFA and EFSA have evaluated both substances. Some studies have explored potential links between polysorbate 80 and gut inflammation, but evidence is mixed and not conclusive at typical consumption levels. Sodium benzoate, when combined with ascorbic acid (Vitamin C) in certain beverages, can form small amounts of benzene, a known carcinogen; however, the FDA states that levels are generally very low and not a concern.
