The hydrogels are tridimensional crosslinked polymeric network with the ability to hold large amount of water. The purpose of this study was to prepare xanthan gum-based polysaccharide hydrogels with polymeric networks and to evaluate their physical and chemical properties. Xathan gum, sodium benzoate, potassium sorbate, HPLC graded water and glycerine was used in the preparation of hydrogels. The physical and chemical properties of hydogels were determined to characterize moisture content, biodegradability, relative hydrogen bonding strength, viscosity and surface morphology of the hydrogel formulations. On the basis of this analysis, hydrogel 04 and 05 with relatively higher xanthan gum concentration were found to be more effective product in comparison with other variations of hydrogels. The reasons behind the effectiveness of these two hydrogels were biodegradability, lower moisture content, higher viscosity and better crosslinking polymeric network morphology.
