Application
Sodium benzoate (CAS 532-32-1) is the sodium salt of benzoic acid, widely used as an antimicrobial preservative in food, beverage, pharmaceutical, and personal care industries. It is most effective at pH ≤ 4.5, inhibiting the growth of yeast, mold, and bacteria. Common applications include carbonated soft drinks, fruit juices, pickles, sauces, salad dressings, jams, and margarine. In pharmaceuticals, it serves as a preservative in liquid medications, syrups, and creams. It is also used as a corrosion inhibitor in antifreeze and coolant formulations. Sodium benzoate is a key intermediate in organic synthesis and acts as a non-toxic stabilizer. Xinchem offers custom synthesis, custom chemical synthesis, and contract manufacturing of high-purity sodium benzoate with flexible scaling from R&D to commercial tons.
