Description

Calciumpropionatehydrate CAS NO 56744-45-7 is the hydrated calcium salt of propionic acid, widely recognized as a highly effective and safe mold inhibitor. This compound is essential for extending the shelf life of various perishable goods by preventing the growth of fungi and bacteria. It is a critical ingredient for manufacturers in the food and feed industries, as well as for applications in pharmaceuticals and cosmetics where microbial control is paramount.

Application

• Food Preservation: Primarily used as an anti-mold agent in baked goods (bread, cakes, tortillas), dairy products (cheeses), and processed meats.
• Animal Feed Additive: Incorporated into feed for poultry, cattle, and swine to prevent spoilage and inhibit mycotoxin-producing molds.
• Pharmaceutical Excipient: Serves as a preservative in certain liquid and semi-solid pharmaceutical formulations to ensure stability.
• Cosmetic Preservation: Used in water-based cosmetic and personal care products to prevent microbial contamination.
• Tobacco Industry: Applied to moist tobacco to suppress mold growth during processing and storage.
• Industrial Applications: Functions as a fungistatic agent in adhesives, paints, and textiles.

Quality Control

Our Calcium Propionate Hydrate is manufactured under strict quality management systems. We offer grades compliant with major international standards, including FCC (Food Chemicals Codex) for food applications and feed-grade specifications. Each batch undergoes rigorous testing for assay, moisture content, heavy metals, and microbiological purity. Certificates of Analysis (COA) are available upon request to ensure full traceability and compliance for your specific application needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation. Keep away from incompatible materials such as strong acids.
