Significance of Swelling time
Swelling time is defined as the duration a hydrogel requires to achieve its equilibrium swelling point when immersed in water. It encompasses the time taken for a hydrogel formulation to swell to its maximum extent, which is essential for its floating behavior. Additionally, swelling time is crucial for the hydrogel's functionality in drug delivery, as it indicates the period necessary for the hydrogel to fully swell in a specific medium. This factor significantly impacts the performance of hydrogels in various applications.
