01
Formulation & freezing
Review ingredient compatibility, the intended dry structure, dose and freezing behaviour.
TECHNOLOGY
Freeze-drying, designed around the formula.
Freeze-drying removes water from a frozen preparation under reduced pressure. The formulation, cycle and package must be evaluated together.
PROCESS PRINCIPLES
From frozen preparation to a dry format.
02
Drying cycle
Develop primary and secondary drying conditions for the specific formulation and equipment.
03
Protection & verification
Evaluate moisture sensitivity, package integrity, stability and the intended use method.
VALIDATION
The evidence matters.
Freeze-drying alone does not establish a product’s shelf life, preservative requirements, microbiological status or performance. Those statements require product-specific assessment and supporting data.
A project review may consider residual moisture, appearance, reconstitution behaviour where applicable, microbiological quality, packaging compatibility and stability under the intended storage conditions. The final testing scope is agreed for the actual product and market.
