Description
Dicalcium Phosphate Anhydrous Granular is a high-purity calcium and phosphorus salt supplied as white, free-flowing granules. As the anhydrous form of calcium hydrogen phosphate, it contains no crystal water, which gives it very low moisture uptake and outstanding physical stability under storage and tableting conditions. The granular form is specifically designed for direct compression: its uniform, coarse particles flow freely into tablet presses, resist segregation in blends and compress into hard, low-friability tablets at high speed. Chemically, it is sparingly soluble in water and insoluble in ethanol, dissolving in dilute acids, which makes it well suited to pharmaceutical and nutritional formulations where controlled solubility is desired. Produced under USP-grade specifications, it delivers consistent calcium and phosphorus content in every batch. With a two-year shelf life, it is a trusted excipient and mineral supplement across pharmaceutical, nutraceutical and food industries. In practice the granules flow from hopper to press with minimal variation, and their low friability keeps tablets intact through coating and packaging. They also contribute both calcium and phosphorus in a single mineral source. Every batch is released against a full quality panel covering appearance, purity, heavy metals and microbiology, so each shipment arrives with documented conformity and traceable batch records. How DCP Anhydrous Granular works: calcium hydrogen phosphate supplies calcium and phosphorus in the same ratio found in bone mineral, which is why it is the classic calcium-phosphorus supplement source. The anhydrous form contains no crystal water, so it absorbs almost no moisture from the air - a property that keeps blends free-flowing and protects moisture-sensitive actives. The granular grade is engineered for direct compression: uniform, coarse particles flow smoothly into tablet dies, resist segregation, and compress into hard tablets at high speed without capping. Practical guidance: in tableting, use it as the primary filler where calcium-phosphorus content is desired; blend it with lubricant at the final stage and compress with moderate force; in nutraceutical premixes it doubles as a mineral source and a flow aid; in oral care it contributes gentle polishing action; and in food fortification it disperses through dry mixes without affecting taste. Quality assurance: produced to USP-grade specifications with assay, loss on ignition, heavy-metal limits including lead, cadmium and mercury, and full microbiological testing per batch, all documented for regulatory files. Packed in polyethylene inner bags with paper-plastic woven outer bags of 25 kg, with a two-year shelf life in dry, ventilated storage. Specification highlights: it is packed in 25kg/bag with a minimum order quantity of 1000kg. Certificates of analysis accompany every shipment, and sample supply, specification customization and flexible payment terms are available for qualified buyers, supported by the standardized seven-step service process from inquiry to after-sales support. Compliance and quality at a glance: the product is manufactured under the standards referenced in its specification sheet, and every batch is tested for identity, purity, heavy metals and microbiology before release. Batch records, test reports and certificates are kept and supplied for buyer qualification, audit and regulatory filing, and the product is stored and shipped in its original packaging to preserve quality through the supply chain. For industrial buyers, this documented quality system means one qualification covers years of consistent supply, with the specification sheet serving as the contractual reference for every delivery.
Applications
In pharmaceutical tableting, it is a preferred direct-compression excipient that provides bulk, flow and hardness with minimal tooling wear. Nutraceutical makers use it in calcium-phosphorus supplements, multivitamin tablets and bone-health formulas. In the food industry it fortifies cereals, bakery products and powdered drinks with calcium and phosphorus, and in oral care it contributes to dentifrice formulations as a polishing and anti-caries ingredient.
Advantages
The anhydrous granular grade was engineered for high-speed direct compression: it flows, blends and compresses predictably, cutting down capping, sticking and machine downtime in large tablet campaigns. Its absence of crystal water keeps hardness and disintegration profiles stable even in humid climates, protecting batch consistency. With USP-grade purity, a two-year shelf life and steady 25 kg bag supply, it is a low-risk choice for tableting operations that cannot afford variation.
