The pharmaceutical industry demands excipients that ensure not only the efficacy and stability of medications but also the smooth and efficient manufacturing of dosage forms. Zinc stearate, a high-purity chemical offered by NINGBO INNO PHARMCHEM CO.,LTD., is a critical excipient widely used in tablet and capsule manufacturing. As a trusted supplier in China, we provide pharmaceutical-grade zinc stearate that meets rigorous industry standards for safety, purity, and performance.

In tablet manufacturing, zinc stearate primarily serves as a lubricant. When added in small concentrations, typically up to 1.5% w/w, it significantly reduces friction between the tablet granules and the punches and dies of the tablet press. This lubrication is essential for preventing sticking and buildup on the machinery, ensuring consistent tablet weight and hardness, and allowing for higher production speeds. The ease with which it adheres to particle surfaces makes it an effective agent for facilitating the ejection of tablets from the die cavity.

Beyond its lubricating function, zinc stearate also acts as a mold release agent, contributing to the efficient production of both tablets and capsules. Its presence prevents the formulation from adhering to the complex surfaces of the manufacturing equipment, minimizing downtime for cleaning and ensuring uninterrupted production runs. This is particularly important for formulations that may have inherent sticking properties.

The use of zinc stearate in pharmaceuticals is supported by its generally recognized as safe (GRAS) status by regulatory bodies when used appropriately. NINGBO INNO PHARMCHEM CO.,LTD. ensures that our zinc stearate adheres to these standards, providing manufacturers with a reliable and safe ingredient. For companies looking to buy zinc stearate for pharmaceutical applications, our product's consistent quality and impurity profile are paramount.
