Sodium Propionate is Colorless transparent crystal or granular crystalline powder with a slight special smell. The monohydrate salt is a colorless crystal with hygroscopicity. It is soluble in water and ethanol, with a solubility of about 100 (15°C) in 10% water and a pH value of 8.5-10.5. It has a wide range of antibacterial effects on molds, yeasts and bacteria, and is most active in acidic pH. Used as a food preservative, suitable for preservatives in pastries and as an antifungal agent for bread. Sodium propionate is almost non-toxic to the human body. The dosage in food is the same as calcium propionate (calculated as propionic acid). The maximum allowable concentration for use in cosmetics is 2% (calculated as propionic acid). It is prepared by neutralizing propionic acid with sodium hydroxide.
