Sodium Benzoate

In the shape of white unscented crystalline powder or granule, Sodium Benzoate can be used as preservatives. Preservatives are food ingredients and food additives that prevent or inhibit spoilage of food due to fungi, bacteria and other microorganisms. It also can be used as chemical analytical reagent for pharmaceutical industry and plant genetic research. As acidic preservative, Sodium Benzoate has no functions of sterilization and bacteria inhibition in alkali mediums. Furthermore, when it is used as the preservative of liquid preparation, Sodium Benzoate can prevent it from spoiling and souring, and prolong its shelf-life.
