Sodium propionate is a colorless transparent crystalline or granular crystalline powder with a slight peculiar smell. Monohydrate salt is a colorless crystal with hygroscopicity. Soluble in water and ethanol, the solubility in 10% water is about 100 (15℃), and the pH value is 8.5~10.5. It has a wide range of antibacterial effects on molds, yeasts and bacteria, and is most active in acidic pH. It is used as a food preservative, suitable for preservatives in cakes and as an antifungal agent for bread. Sodium propionate is almost non-toxic to humans. The amount 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
