“…Hydroxypropyl methylcellulose in a formulation increased this score, while polyethylene oxide lowered it. The linear polymer structure of PEO suggests fast water binding ability but also the formation of weaker, erodible gels [ 101 , 103 ]. Therefore, in the presence of factors facilitating erosion of the polyethylene oxide gel, the swelling intensity is not as prominent, as seen from this study's experimental data.…”
