Applications of Sodium benzoate Prill

1. 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.

2. 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.

3. Other sodium benzoate uses

Sodium benzoate granule can also be found in other products such as cosmetics and pharmaceuticals where it acts as a corrosion inhibitor, fragrance ingredient, and preservative. 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.
