ABSTRACT:
Method for imparting superior viscosity to an aqueous polysaccharide solution comprises prehydrating polysaccharide in fresh and deionized water. The viscosity imparted to the final aqueous solution by this method is greater than the viscosity of an aqueous polysaccharide solution initially hydrated in hard water. Alternatively, the polysaccharide solution in fresh water may be used alone or diluted with water containing inorganic ions.
