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 (see formula I) in which n is an integer from 3 to 17 and R1 and R2 are C1 to C4-alkyl, C1 to C4-hydroxyalkyl or hydrogen, with the proviso that only one of the two substituents R1 and R2 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.
