Samples are placed in environmental chambers at elevated temperatures (typically 40°C and 45°C) alongside a control sample at room temperature. Three months at 45°C under high humidity is generally accepted as a simulator for two years of real-time shelf stability.
Every water-containing cosmetic requires validation through a formal Microbiological Challenge Test (such as USP or ISO 11930).
