Abstract
Compositions of matter, desirably in powder form, adapted for ready dispersion/dissolution in an aqueous medium, and which rapidly provide maximum viscosity values therefor, are comprised of an intimate admixture of a water soluble gum or polymer, a dispersion/dissolution enhancing amount of a water donor material, and, advantageously, an anionic and/or nonionic surfactant.
