ABSTRACT:
Surface properties of solutions of fluorinated surfactants are improved by employing a fluorinated synergist (R.sub.f).sub.n T.sub.m Z wherein R.sub.f is a perfluorinated aliphatic group, T is alkylene, arylene, alkylenethio alkylene, alkyleneoxyalkylene or alkyleneiminoalkylene, Z is a neutral or a polar group, n is 1 or 2 and m is 0 to 2. The resulting synergistic surfactant compositions are useful for all applications where surfactants are employed.
