Abstract
Low viscosity, concentrated aqueous solutions of polysaccharide gums are prepared using certain water-soluble, anionic copolymers as viscosity reducers. These low viscosity polysaccharide gum solutions are used in the formulation of low viscosity polar-solvent fire-fighting foam compositions, especially "3.times.3" ("three by three") concentrates. The low viscosity compositions of the present invention are found to have exceptional stability as well as significantly improved fire-fighting performance.
