    • Ionic N-containing compounds of the general formula (I), wherein the index n is the number 0 or 1 and the radicals R1 to R5 independently from each other are hydrogen or alkyl, cycloalkyl or aryl radicals with 1 to 25 carbon atoms, wherein the alkyl radicals can be saturated or olefinically unsaturated, straight-chained or branched, and the cycloalkyl radicals can be saturated or olefinically unsaturated, with the following stipulations: (1) if n = 1, at least one of the radials R1 to R5 must contain up to 25 carbon atoms, (2) if n = 0, at least one of the radicals R1, R2, R3 or R5 must contain 8 to 25 carbon atoms, (3) the carbon atoms carrying the radicals R2 and R3 are linked via a C-C-single bond or a C=C-double bond, (4) in the radicals R1 to R5 - if they are alkyl or cycloalkyl radicals - a hydrogen atom linked to a carbon atom can be substituted with an -OH or NH2 group, or an -O-, -COO- or -NH- group can be inserted between two neighboring carbon atoms linked via a C-C single bond, (5) in the radicals R1 to R5 - if they are aryl radicals - a hydrogen atom linked to a carbon atom can be optionally substituted with an alkyl or cycloalkyl group having 1 to 12 carbon atoms, with the stipulation that the following applies to said alkyl or cycloalkyl group: optionally a hydrogen atom linked to a carbon atom can be substituted with an -OH or NH2 group or an -O-, -COO- or -NH- group can be inserted between two neighboring carbon atoms linked via a C-C-single bond, said compounds being suitable as temporary surfactants, particularly for the production of aqueous emulsions or dispersions.
