  • Food Preservatives

    Sodium benzoate is the first preservative the FDA allowed in foods and still a widely used food additive. It’s classified as Generally Recognized As Safe (GRAS), meaning that experts consider it safe when used as intended.

    It’s approved internationally as a food additive and is assigned the identifying number 211. For example, it’s listed as E211 in European food products.

    Sodium benzoate inhibits the growth of potentially harmful bacteria, mold, and other microbes in food, thus deterring spoilage. It’s particularly effective in acidic foods. Therefore, it’s commonly used in foods, such as soda, bottled lemon juice, pickles, jelly, salad dressing, soy sauce, and other condiments.

  • Pharmaceutical

    Sodium benzoate is used as a preservative in some over-the-counter and prescription medications, particularly in liquid medicines like cough syrup.

    Additionally, it can be a lubricant in pill manufacturing and makes tablets transparent and smooth, helping them break down rapidly after you swallow them.

    Lastly, larger amounts of sodium benzoate may be prescribed to treat elevated blood levels of ammonia. Ammonia is a byproduct of protein breakdown, and blood levels may become dangerously high in certain medical conditions.
