Perform Humidity-Dependency Testing for Hygroscopic Formulations
Understanding the Tip: Why humidity poses a risk to hygroscopic products: Hygroscopic formulations—such as certain tablets, powders, and granules—readily absorb moisture from the environment. This can lead to changes in appearance, hardness, dissolution, potency, or microbial growth, compromising product quality and safety. Without specific humidity-stress testing, developers may miss key degradation pathways or underdesign packaging…
