Insight into the dust explosion hazard of pharmaceutical powders in the presence of flow aids
Journal of Loss Prevention in the Process Industries, 2022Coating of nanoscale flow aids is widely used in pharmaceutical applications to increase the flowability of cohesive powders. For combustible pharmaceutical active ingredients and excipients, it is unclear whether increased flowability affects the dust ...
