Accelerated Stability Testing

A method for predicting long-term ingredient or product stability by exposing samples to elevated temperature and humidity conditions (typically 40°C/75% relative humidity per ICH Q1A guidelines) for a defined period and extrapolating real-time stability outcomes using mathematical degradation models (typically the Arrhenius equation). Used to establish or validate retest dates and shelf-life claims without waiting the full real-time period. Results should always be confirmed by at least some real-time stability data before labeling claims are finalised.
