Description

Calcium Adipate is a white, crystalline salt of adipic acid, a key dicarboxylic acid. This compound serves as a versatile and effective calcium source and acid regulator in various industrial and food-grade applications. It is primarily sought after by manufacturers in the food, pharmaceutical, and polymer industries for its functional properties and regulatory compliance. Its consistent quality and reliable performance make it a critical ingredient for formulators requiring precise pH control and mineral fortification.

Application

• As a food additive (E 356) for pH regulation, firming agent, and sequestrant in processed foods.
• As a calcium source in nutritional supplements and pharmaceutical formulations.
• As a stabilizer and acid scavenger in polymer processing, particularly for polyamides (nylon).
• As a curing agent or catalyst component in specialty resin and adhesive systems.
• As a precursor or intermediate in fine chemical and pharmaceutical synthesis.
• In laboratory research as a reagent for studying calcium-mediated processes.

Quality Control

Our Calcium Adipate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets the required specifications for identity, purity, and safety. We can supply material compliant with Food Chemical Codex (FCC) and pharmaceutical-grade standards where applicable. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability and consistency.

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 material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
