Compounds, in particular those based on polyisobutyleneamines, are suitable as emulsifiers for water-in-oil emulsions and are used in particular as additives for fuels and lubricants. The novel compounds are those of the formula I where R<1 >is unsubstituted or C1-C12-alkyl-substituted C1-C8-alkylene or C2-C8-alkenylene, R<2 >is linear or branched C8-C350-alkyl or C8-C350-alkenyl, R<3 >and R<4>, independently of one another, are each H, methyl or ethyl and together have not more than 2 carbon atoms, R<5 >is H, M<+>, SO3H, SO3<->M<+>, OPO3H, OPO3<->M<+> or C(O)R<7>, M<+> is NH4<+>, an alkali metal ion or 0.5 alkaline earth metal ion, R<7 >is a linear C2- to C10-hydrocarbon radical substituted by at least one hydrophilic group and y and z, independently of one another, are each an integer from 0 to 50, and R<5 >is H if y is 0, and R<6 >is H if z is 0.
