Characterization of physicochemical properties of perfluorodecanoic acid-polyquaternium cellulose hydrogel

► PQ10-PFDA association is set by electrostatic interaction. ► In the region of 1:0.5 ammonium:carboxylic group molar ratio the complex form strong hydrogels. ► Hydrogel structure is maintained in a wide range of conditions. ► Hydrogel also presents an unexpected increased mucoadhesion properties.
