ABSTRACT:
The instant invention relates to the use of ion-pair complexes derived from anionic perfluoroalkyl sulfonates, carboxylates, phosphates and phosphonates and cationic perfluoroalkyl surfactants. Such complexes are capable of reducing the surface tension of aqueous solutions dramatically even at extremely low concentrations, and are useful as wetting, spreading and leveling agents and are especially preferred as components in so-called aqueous film forming foam compositions for fighting polar and non-polar solvent and fuel fires.
