Bulkiness

Definition of Bulkiness:

• Bulkiness affects flow, compressibility, and formulation quality in pharmaceuticals.
• The reciprocal of bulk density. Indicates how much volume a given mass of powder occupies.

  $B = \tfrac{1}{\rho_{b}} \; \text{(Bulkiness)}$

• Units: cm³/g
• A bulky powder has low bulk density and occupies more volume.

Importance:

• High bulkiness = light, fluffy powder
• Important for container size, transport, and dose uniformity
