Citric acid is the most widely used organic acid and pH-control agent in foods, beverages, pharmaceuticals and technical applications. Used in pharmaceutical preparations, especially in effervescent tablets. It is used as a natural preservative. Citric acid anhydrous is non-toxic. It is chemically stable if stored at ambient temperatures. Stability tests have shown that citric acid anhydrous is chemically stable for at least five years in tightly closed containers under proper storage conditions. Hygroscopic.
