Description

Magnesium Dipropionate is a versatile inorganic salt of propionic acid, offering excellent functional properties as a preservative and acidity regulator. This compound is valued for its ability to inhibit mold and bacterial growth while maintaining product stability and safety. It is a critical ingredient for manufacturers in the food, feed, and pharmaceutical industries seeking effective and compliant additives for their formulations.

Application

• Food Preservation: Used as an effective mold and rope inhibitor in baked goods, cheeses, and other perishable food products.
• Animal Feed Additive: Acts as a preservative and anti-fungal agent in feed and silage to prevent spoilage and ensure nutritional quality.
• Pharmaceutical Excipient: Serves as a buffering agent and stabilizer in certain medicinal formulations and dietary supplements.
• Industrial Biocide: Employed in water treatment systems, adhesives, and paints to prevent microbial contamination.
• Personal Care Products: Functions as a pH adjuster and preservative in cosmetics and personal hygiene items.

Quality Control

Our Magnesium Dipropionate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for purity, identity, and safety. Certificates of Analysis (COA) are provided with every shipment, confirming compliance with relevant standards such as FCC for food-grade applications. We support our clients with full traceability and documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent caking and degradation. Recommended storage temperature is between 15°C and 25°C.
