Water Activity Control

Water activity control maintains formulation moisture levels preventing microbial growth and degradation. Water activity measurement using hygrometers quantitates available water. Desiccant inclusion reduces water activity. Packaging barriers minimise moisture ingress. Stability studies confirm water activity maintenance.

Regulatory specifications establish acceptable limits. Manufacturing controls prevent elevated water activity. Quality monitoring detects moisture ingress. Post-approval surveillance confirms maintenance. Emerging measurement improves water activity assessment.
