Are you curious about how additives can influence the electrostatic charge build-up of excipients in pharmaceutical manufacturing? Join us on a journey to uncover the hidden dynamics of powder flow and electrostatic charge accumulation, a crucial aspect of powder processing that can significantly affect the quality and efficiency of pharmaceutical production.

The Importance of Powder Flow in Pharmaceuticals

In the pharmaceutical industry, achieving good flowability of powders is essential for maintaining product quality. However, the frictional contact between powder particles during flow generates electrostatic charges through a phenomenon known as the triboelectric effect. These accumulated charges can lead to undesirable effects such as reduced flowability, particle sticking, and unpredictable mass flow variations.

Our Collaborative Study with Granutools

In a recent study, we collaborated with Granutools to investigate the influence of additives on the tribocharging behavior of two commonly used excipients, microcrystalline cellulose (MCC) and Starch 1500®, using Granutools’ advanced GranuCharge instrument. Our research aimed to understand how additives can mitigate the adverse effects of tribocharging, offering insights into improving powder processing in pharmaceutical manufacturing.

The Role of Additives in Charge Reduction

The study focused on three common additives: Syloid® S244, Magnesium Stearate (MgSt), and Aerosil® 200. By systematically evaluating their impact on the electrostatic behavior of the excipient/additive blends, we gained valuable insights into charge reduction and overall processing performance.

Variability Across Excipients and Additives

Our findings revealed significant reductions in charge build-up for all excipient/additive combinations. However, the influence of additives varied depending on the specific excipient used. For instance, Syloid S244 demonstrated exceptional performance when combined with Starch 1500, while Aerosil 200 showed remarkable results with MCC.

Optimizing Additive Concentration

Furthermore, we observed that the effectiveness of additives was not solely dependent on their concentration. In some cases, an optimum concentration was identified, and exceeding this threshold resulted in reduced charge reduction. These results underscore the importance of systematically characterizing the influence of additives on powder tribocharging behavior.
