Dicalcium Phosphate

Dicalcium Phosphate – Pharmaceutical-Grade Capsule & Tablet Excipient

Dicalcium Phosphate is a high-quality pharmaceutical excipient commonly used in capsule filling and tablet compression as a reliable diluent and binder. Valued for its excellent compressibility, low moisture content, and chemical stability, dicalcium phosphate supports efficient manufacturing while helping produce consistent, high-strength tablets and capsules. It is particularly well suited for direct compression applications where formulation stability and uniform dosing are critical, making it a popular choice in dietary supplements, vitamins, and pharmaceutical products.

As a non-hygroscopic and chemically inert material, dicalcium phosphate does not readily absorb moisture and does not react with active ingredients. This makes it ideal for moisture-sensitive formulations and helps maintain long-term product stability without compromising flow or tablet integrity.

Key Benefits of Dicalcium Phosphate

• Excellent compressibility for direct compression
• Low moisture absorption for improved stability
• Chemically inert and non-reactive
• Supports uniform tablet weight and hardness
• Improves formulation consistency
• Odorless and tasteless

Ideal Diluent & Binder for Capsules and Tablets

Dicalcium phosphate functions primarily as a diluent and binder, providing bulk and structural strength to tablets and capsules without interfering with active ingredients. Its favorable flow and compression characteristics allow manufacturers to achieve precise dosing and durable tablets while maintaining efficient production speeds.

Dicalcium phosphate is commonly used in:

• Capsule filling
• Direct compression tablets
• Vitamin and mineral supplements
• Dietary supplement manufacturing
• Pharmaceutical formulations

Manufacturing Efficiency & Performance

Because of its strong compaction properties, dicalcium phosphate supports high-speed tablet production with minimal processing steps. Its low hygroscopicity reduces issues related to moisture, helping prevent capping, sticking, and degradation of moisture-sensitive components. The result is a smoother manufacturing process with consistent, repeatable outcomes.

Safety, Quality & Compatibility

Dicalcium phosphate is widely recognized as safe and is extensively used across the pharmaceutical and supplement industries. In addition to its role as an excipient, it also serves as a source of calcium and phosphorus in many formulations. Its inert nature and broad compatibility with other excipients and APIs make it a dependable ingredient for modern capsule and tablet production.
