Application: Calcium propionate is a commonly used preservative, widely applied in the processing of foods such as bread and pastries. It exhibits effective inhibitory properties against mold, yeast, and bacteria, thereby extending the shelf life of food products. Moreover, calcium propionate is virtually non-toxic to humans, making its use in both food and cosmetics safe. In cosmetics, calcium propionate is often utilized as a preservative, with a maximum allowable concentration typically around 2% (based on propionic acid).

Storage: Calcium propionate should be stored in dry, cool warehouses, away from heat sources and direct sunlight. During storage and transportation, precautions should be taken to prevent moisture and rain, avoiding product dampness and clumping that may affect quality.
