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 particularly valued by manufacturers in the food, pharmaceutical, and polymer industries for its stability and functionality. The product is supplied under the identifier CAS NO 22322-28-7.

Application

• Food Additive: Used as a firming agent, acidity regulator, and calcium fortifier in processed foods, baked goods, and dairy products.
• Pharmaceutical Excipient: Functions as a calcium supplement and a tablet disintegrant or binder in solid dosage formulations.
• Polymer Industry: Acts as a heat stabilizer and acid scavenger in PVC and other polymer systems to prevent degradation.
• Chemical Synthesis: Serves as a precursor or intermediate in organic synthesis and the production of other adipate salts.
• Animal Nutrition: Incorporated into feed as a source of bioavailable calcium for livestock and poultry.
• Adhesive & Sealant Formulations: Utilized as a filler or modifying agent to enhance specific properties.

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 relevant standards such as FCC (Food Chemicals Codex) for food-grade applications. A detailed Certificate of Analysis (COA) is provided with every shipment.

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 opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
