ABSTRACT:
This invention provides a novel dry blend composition adapted for application as a thickening agent in aqueous solutions. The composition consists essentially of an admixture of a polygalactomannan gum and a copolymer containing carboxylate groups.
The invention composition contributes exceptionally high viscosity to an aqueous solution due to a synergistic viscosity effect derived from the interaction of the polygalactomannan and copolymer components.
