Description

Phosphoric Acid, Calcium Salt (1:) is a key inorganic calcium phosphate compound, primarily known as monocalcium phosphate. This product is valued for its role as a highly bioavailable source of calcium and phosphorus, essential for nutritional and industrial formulations. It is a critical ingredient for manufacturers in the food, feed, and fertilizer industries, where precise mineral content and solubility are required. Our supply ensures consistent quality and reliable availability for global B2B partners.

Application

• Food & Beverage Additive: Used as a leavening agent in baked goods, a nutrient fortifier in cereals and beverages, and a pH regulator.
• Animal Feed Supplement: Serves as an essential mineral source (calcium and phosphorus) in premixes for livestock, poultry, and aquaculture to support bone health and growth.
• Fertilizer Industry: Acts as a water-soluble phosphorus source in specialty fertilizers and nutrient solutions for hydroponics and controlled-release agriculture.
• Dental Products: Employed in the formulation of toothpaste and dental creams as a gentle abrasive and remineralizing agent.
• Pharmaceutical Excipient: Used as a diluent or calcium source in tablet and capsule formulations.
• Industrial Processes: Functions in metal surface treatment, as a component in fire retardants, and in ceramic glazes.

Quality Control

Our Phosphoric Acid, Calcium Salt (1:) is produced and tested under a rigorous quality management system. We offer grades compliant with relevant industry standards such as FCC (Food Chemicals Codex) for food applications and feed-grade specifications. Every batch is accompanied by a detailed Certificate of Analysis (COA) to ensure traceability and verify parameters like assay, heavy metal content, and loss on drying. Certifications including ISO 9001 underpin our commitment to consistent quality.

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 after opening to prevent caking and degradation due to atmospheric moisture. Keep away from incompatible materials such as strong bases.
