Description

Pentacalcium Bis(Triphosphate) is an inorganic phosphate compound with the chemical formula Ca5(P3O10)2. This material serves as a critical functional ingredient, primarily valued for its role as a calcium and phosphate source and its ability to modify rheological properties. It is essential for manufacturers in the food, pharmaceutical, and industrial sectors seeking consistent quality and reliable supply. Its specific properties make it suitable for applications requiring controlled mineral release and stabilization.

Application

• Food Additive: Used as a calcium fortifier, pH regulator, and texturizing agent in processed foods, dairy products, and baking powders.
• Pharmaceutical Excipient: Functions as a tablet disintegrant, binder, and a source of bioavailable calcium and phosphate in nutritional supplements and solid dosage forms.
• Dental Care Formulations: Incorporated into toothpaste and oral care products for its remineralization properties and abrasive qualities.
• Industrial Applications: Acts as a corrosion inhibitor in water treatment systems, a dispersing agent in ceramics, and a component in specialty detergents.
• Animal Feed Supplement: Provides essential dietary calcium and phosphorus for livestock and poultry nutrition.

Quality Control

Our Pentacalcium Bis(Triphosphate) is manufactured under a strict quality management system. Each batch is tested to ensure it meets specifications for identity, purity, and heavy metal content, aligning with standards such as FCC (Food Chemicals Codex) and Pharmaceutical grades where applicable. A comprehensive Certificate of Analysis (COA) documenting all test results is provided with every shipment to guarantee traceability and compliance.

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 caking and degradation from atmospheric moisture.
