In the highly regulated pharmaceutical industry, the selection of excipients plays a crucial role in the efficacy, stability, and manufacturability of drug products. Calcium Stearate (CAS: 1592-23-0), a white, waxy powder, stands out as a versatile and widely utilized pharmaceutical excipient, performing essential functions as a lubricant and flow agent. NINGBO INNO PHARMCHEM, a reputable chemical supplier, provides pharmaceutical manufacturers with high-purity Calcium Stearate to meet their exacting demands.

The Essential Functions of Calcium Stearate in Tablet Manufacturing

The primary application of Calcium Stearate in pharmaceuticals is as a lubricant in tablet manufacturing. During the tableting process, the compression of the powder blend into tablets can lead to significant friction between the punches and the die wall, as well as the material and the die. This friction can cause sticking, capping (lamination), and lamination of tablets, leading to production inefficiencies and compromised product quality. Calcium Stearate, when added in small percentages (typically 0.5-2% w/w), effectively reduces this friction. It forms a thin film on the surface of the granules or powder blend, ensuring smoother ejection of the compressed tablet from the die and preventing adherence to the tooling.

Beyond its lubricating properties, Calcium Stearate also acts as a glidant or flow agent. It helps to improve the flowability of the powder blend, ensuring uniform die filling during the compression process. This is critical for achieving consistent tablet weight and hardness, which are key quality attributes in pharmaceutical manufacturing. By enhancing the flow characteristics, Calcium Stearate contributes to a more robust and reproducible manufacturing process.
