In the pharmaceutical industry, the selection of excipients is as critical as the active pharmaceutical ingredients (APIs) themselves. These inactive substances play vital roles in drug formulation, affecting everything from tablet disintegration and drug release to manufacturing efficiency. Zinc Stearate, a widely recognized metallic soap, is a highly valued excipient, particularly for its lubricating and binding properties in tablet and capsule manufacturing. NINGBO INNO PHARMCHEM CO.,LTD. is a premier manufacturer and supplier of pharmaceutical-grade Zinc Stearate, ensuring the purity and performance required for your critical drug products.

Zinc Stearate, a fine white powder (CAS 557-05-1), is extensively used in the pharmaceutical sector primarily as a tablet lubricant. During the high-speed compression of powders into tablets, friction between the powder blend and the punch and die surfaces can lead to sticking, capping, and tablet breakage. Zinc Stearate effectively reduces this friction, ensuring smooth tablet ejection from the die cavity and preventing damage to both the tablets and the manufacturing equipment. This improves overall production efficiency and ensures consistent tablet quality.

Beyond its lubricating function, Zinc Stearate also acts as a glidant, improving the flowability of powder mixtures. Good flow is essential for uniform die filling during tablet compression, ensuring consistent tablet weight and dosage accuracy. By reducing inter-particulate friction, Zinc Stearate helps powders move more freely, facilitating precise dosing and efficient manufacturing.

The compound's binding properties are also beneficial. In some formulations, Zinc Stearate can help hold the tablet together, contributing to its mechanical strength and preventing it from crumbling. Its hydrophobic nature can also influence the disintegration and dissolution rates of the API, which must be carefully considered during formulation development.
