ABSTRACT:
The disclosure relates to aqueous compositions which comprise water soluble fluorinated surfactant, fluorinated synergist, ionic non-fluorochemical surfactant, nonionic non-fluorochemical surfactant, electrolyte, and solvent. This composition is a concentrate which when diluted with water spreads on fuel surfaces suppressing vaporization. Because of this property the aqueous solutions of the above compositions are effective as agents for fire fighting.
