Description
Dicalcium Phosphate Anhydrous Powder 100-350 Mesh is an anhydrous calcium hydrogen phosphate milled to a precisely controlled particle size range between 100 and 350 mesh. This fine, white powder offers the same low-moisture, stable mineral profile as standard anhydrous DCP, with an extra degree of particle control that gives formulators uniform dispersion and a smooth, consistent blend with active ingredients. The controlled mesh range supports reliable content uniformity in low-dose tablets and capsules, where oversized particles could otherwise cause segregation or weight variation. Sparingly soluble in water and insoluble in ethanol, it releases calcium and phosphorus in a gentle, predictable manner suited to nutritional supplementation. Produced to USP specifications with a two-year shelf life, this grade is the refined choice for manufacturers who demand tighter particle control in pharmaceutical and nutraceutical production. The fine cut also gives tablets a smooth, uniform surface finish. In practice the controlled mesh range lets formulators predict blend behavior and tablet weight variation before scale-up, saving trial batches. It is especially suited to low-dose actives where uniformity is critical. Consistent batch-to-batch quality is maintained through defined raw-material sourcing and in-process control, protecting formula stability for industrial buyers. How the 100-350 Mesh grade differs: this cut of anhydrous DCP is milled to a precisely controlled particle-size window, removing the coarse and ultra-fine fractions that cause segregation and weight variation in tableting. For low-dose actives, where a few percent of blend variation can shift label claims, this particle control is what keeps every tablet within specification. The chemistry remains anhydrous calcium hydrogen phosphate, delivering calcium and phosphorus with very low moisture pickup. Practical guidance: use this grade in wet granulation and dry blending of high-precision pharmaceutical products; it compresses into hard, smooth tablets and assists disintegration through its porous packing; in capsules it gives consistent density and mineral content; in powder sachets it disperses cleanly; and in oral care it contributes controlled polishing characteristics. Quality assurance: produced to USP specifications with particle-size distribution, assay, heavy metals and microbiology tested per batch, and documentation provided for every shipment. Packed 25 kg per bag with polyethylene inner and woven outer layers, with a two-year shelf life in dry, ventilated storage. For manufacturers who have experienced weight-variation or segregation problems with standard DCP grades, this controlled-mesh version is the practical upgrade. 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. Documented quality from batch to batch: every production lot is verified against the full specification - identity, purity, heavy metals and microbiology - before release, and the resulting certificates and batch records travel with each shipment to support qualification and audit. Raw materials are sourced to defined standards, storage follows the conditions stated in the specification, and the product ships in its original, intact packaging. Shelf life and storage requirements are clearly documented, so purchasing, warehouse and quality teams all work from the same reference. This repeatable quality system is what makes the grade dependable for multi-year supply agreements.
Applications
It is used in wet granulation and dry blending of pharmaceutical tablets where fine particle control improves dose uniformity. Nutraceutical makers select it for calcium-phosphorus capsules, powder sachets and effervescent formulas. Food producers use it to fortify flour-based products, milk powders and cereals with an invisible, taste-neutral mineral source. Oral care applications use the fine powder in toothpaste polishing systems.
Advantages
The tightly controlled 100-350 mesh cut removes the particle-size variability that causes segregation and weight variation, so every unit dose stays within specification. Its anhydrous, low-moisture nature keeps blends free-flowing and stable in humid production environments. USP-grade quality and a two-year shelf life make it a precise, low-risk mineral excipient for high-consistency formulations.
