Cosmetic ingredients such as collagen, vial freeze-dried powder, foundation powder, masks and freeze-dried balls are evaluated on stability, microbiological control and the claims the finished product must support. The drying route must preserve the active and produce a powder that reconstitutes or disperses cleanly.
Pain points we solve
Active degradationCollagen and actives degrade with heat; a low-temperature route protects what stability testing confirms.
Powder textureDispersibility and skin feel depend on particle and cake structure from the freezing step.
Microbial safetyFinished-product safety is a process control, not an afterthought.
Claim supportStability and activity data back the claims the product makes.
What to test
- Starting solids and formulation.
- Residual moisture and stability over time.
- Microbiological and safety requirements.
- Packaging and storage conditions.

A pilot unit screens the formulation; a biomedical dryer or spray freeze dryer scales it. See pilot to production and moisture and packaging.
