Description

Potassium Hydrogen Dipropionate is a versatile potassium salt of propionic acid, functioning as a highly effective preservative and pH regulator. Its primary value lies in its dual-action capability to inhibit microbial growth while providing a source of bioavailable potassium, making it a multifunctional additive. This compound is essential for manufacturers in the food and feed industries seeking safe, efficient, and compliant preservation solutions for a wide range of products.

Application

• Food Preservation: Used as an antimicrobial agent in baked goods, dairy products, and processed meats to extend shelf life and prevent mold and bacterial growth.
• Animal Feed Additive: Serves as a preservative in feed and silage to prevent spoilage and as a source of dietary potassium for livestock nutrition.
• pH Control Agent: Functions as a buffering agent and pH stabilizer in various food systems and industrial processes.
• Personal Care & Cosmetics: Employed as a preservative in formulations where a safe, skin-compatible ingredient is required to maintain product integrity.
• Industrial Biocide: Applied in water treatment systems, adhesives, and polymer emulsions to control microbial contamination.
• Pharmaceutical Excipient: Can be used as a stabilizing agent and pH adjuster in certain medicinal preparations.

Quality Control

Our Potassium Hydrogen Dipropionate is manufactured under a strict quality management system. We offer grades compliant with relevant food safety regulations, including FCC (Food Chemicals Codex) guidelines where applicable. Every batch is tested to ensure it meets stringent specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance 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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or reduced efficacy.
