Introduction:
Potassium Sorbate is a mild, highly effective, broad-spectrum preservative used widely in food products, cosmetics, pharmaceuticals, and personal care items. It prevents the growth of mold, yeast, and fungi, thereby extending the shelf life of water-based formulations. Odorless and tasteless in low concentrations, it is approved for use in both natural and synthetic formulations.
