Abstract
The rheological properties of a physically linked hydroalcoholic gel obtained from a binary system consisting of xanthan and of galactomannan from the seeds of Mimosa scabrella (X:GB) with a low Man:Gal ratio of 1.1:1 were compared to those of guar gum (Man:Gal ratio 1.5:1, X:GG). The rheological analysis demonstrated an improvement of strength of X:GB and X:GG hydrogels after dispersion of the polysaccharides in buffer with 1,2-propanediol. The addition of ascorbic acid to these hydrogel formulations resulted in a slight decrease of gel strength. Both hydrogels presented rheological stability over 12 weeks at ambient temperature.
