Which of the following is considered a Critical Quality Attribute (CQA) for powdered and granule products?
|
Particle size. |
|
Particle size affects flowability, mixing uniformity, dissolution, and overall performance in powdered and granule products
|
It directly impacts product quality and processing, while color, taste, smell, and packaging do not affect powder performance
