Sodium benzoate used as a preservative in food 

Sodium benzoate is a preservative commonly used in fruit pies, jams, beverages, salads, relishes, and sauerkraut—foods that have an acidic pH. It also naturally occurs in and some spices such as cloves and cinnamon. Soft drinks are the number one source of sodium benzoate in the diet.

As chemical preservatives, sodium benzoate is frequently used in processed foods to prevent the growth of bacteria, yeast, or other unwanted microorganisms that could spoil your food. When sodium benzoate is combined with water, benzoic acid is produced. Benzoic acid is the active form of the preservative—the form that protects foods.



Other usages of sodium benzoate

Sodium benzoate is used mainly as a food preservative but can also be found in other products such as cosmetics and pharmaceuticals where it acts as a corrosion inhibitor, fragrance ingredient, and preservative.  As a preservative, sodium benzoate is primarily an anti-fungal agent but also has some effectiveness against bacteria.  It is not a broad-spectrum preservative for cosmetic use and should be combined with other preservatives.  Sodium benzoate is often combined with potassium sorbate in low pH products in order to benefit from the ingredients’ synergistic effects against yeast and mold.  When combined with caffeine, it can have a sunscreen effect and provide UVB protection with antioxidant activity.
