A moisture sorption isotherm depicts the alteration in water activity (aw) as water is absorbed into and released from a product under constant temperature conditions. This connection is intricate and distinct for each product.
The variables influencing sorption isotherms encompass temperature, water activity, and the nature of the material under investigation. The parameters impacting sorption isotherms involve moisture content, water activity, and the type of material being examined.
The isotherms were established utilizing a dynamic vapor sorption analyzer under varying humidity levels (ranging from 0% to 90% relative humidity) and across three temperatures relevant to pharmaceutical contexts (20°C, 30°C, and 40°C).
