What type of issue is 'whiskering' associated with in tablet formulation?

Whiskering is associated with cracking or chipping of the tablet in tablet formulation. This phenomenon occurs primarily during the manufacturing process, particularly during the compression stage. When a tablet is formed, the particles within the formulation must bond effectively to create a solid, cohesive tablet structure. If the binding is inadequate or if there is excessive stress during compression, small fragments or layers of the tablet can separate from the main body, leading to visible defects such as cracks or chips.

These defects compromise the integrity of the tablet, affecting not only its physical appearance but also its functionality, including breakage during handling or transportation, and potential issues with dosage uniformity. Recognizing and addressing whiskering is crucial in tablet formulation to ensure product quality and performance.
