Sodium propionate is a colorless, transparent crystal or granular crystalline powder with a slightly characteristic odor. Its monohydrate form is a colorless crystal and hygroscopic. It is soluble in water and ethanol, with a solubility of approximately 100 in 10% water (15°C), and a pH range of 8.5–10.5.
It has broad-spectrum antibacterial activity against molds, yeasts, and bacteria, and is most reactive at acidic pH levels. It is used as a food preservative, suitable for use as a preservative in pastries and as a mold inhibitor in bread. Sodium propionate is virtually non-toxic to humans. Its usage in food is the same as calcium propionate (calculated as propionic acid). The maximum permissible concentration in cosmetics is 2% (calculated as propionic acid). It is produced by neutralizing propionic acid with sodium hydroxide.

Sodium propionate functions as an effective preservative and mold inhibitor. It is widely used in food products (like bread and pastries), animal feed, and industrial applications (such as adhesives and coatings) to prevent the growth of mold and bacteria.
Sodium propionate features broad-spectrum antibacterial activity against molds, yeasts, and bacteria, and it is most active and reactive at acidic pH levels.
Yes, sodium propionate is virtually non-toxic to humans. Its usage and safety limits in food are calculated in the same way as calcium propionate.
Yes, it can be used in cosmetics. The maximum permissible concentration allowed in cosmetic formulations is 2% (calculated as propionic acid).
It should be stored in a cool, dry place. Keep it away from strong light and heat sources to ensure it retains its quality throughout its 2-year shelf life.
Sodium propionate is highly soluble in water and ethanol, with a solubility of approximately 100 in 10% water at 15°C, and it exhibits a pH range between 8.5 and 10.5.
