ABSTRACT:
New saturated fluoroalkylamines and carboxyalkylbetaines and alkylsulfobetaines derived therefrom, and mixtures containing the new fluoroalkylamines and mixtures containing the new fluorobetaines are described. The saturated fluoroalkylamines conform to the formula below ##STR1## in which n is an integer from 3 to 17 and R.sup.1 and R.sup.2 are C.sub.1 to C.sub.4 -alkyl, C.sub.1 to C.sub.4 -hydroxyalkyl or hydrogen, with the proviso that only one of the two substituents R.sup.1 and R.sup.2 is hydrogen. The carboxyalkylbetaines and sulfobetaines and the mixtures thereof are highly effective products for reducing the surface tension of water/air systems and the interfacial tension of water/hydrocarbon systems.
