Description

Metaphosphoric Acid, Calcium Salt is an inorganic chemical compound widely utilized as a sequestrant and stabilizer. Its primary commercial value lies in its ability to bind metal ions, which is critical for preventing undesirable reactions and maintaining product stability in various formulations. This makes it a key ingredient for manufacturers in the food, pharmaceutical, and industrial sectors seeking to enhance shelf-life and performance.

Application

• Food Additive: Used as a sequestrant (E 450(viii)) to stabilize color, flavor, and texture in processed meats, dairy products, and canned goods.
• Pharmaceutical Excipient: Acts as a stabilizing agent in tablet and capsule formulations to prevent degradation of active ingredients.
• Nutraceutical & Dietary Supplements: Serves as a source of calcium and phosphorus in mineral fortification blends.
• Water Treatment: Functions as a corrosion and scale inhibitor in industrial water systems.
• Technical & Industrial Applications: Employed in metal surface treatment, ceramics, and as a flux in soldering applications.
• Laboratory Reagent: Used in analytical chemistry for specific ion sequestration and as a buffer component.
