Abstract

The invention relates to amphiphilic compounds of general formula (I), (R1, R3—C1-C22 hydrocarbon radical, R2—spacer, X, Y—functional groups, Z—1 to 10) with at least two hydrophilic and at least two hydrophobic groups on the basis of amides. The amphiphilic compounds of this invention are highly surface-active and are suitable in particular as emulsifiers, demulsifiers, detergents, dispersants and hydrotropics in industry and household, e.g. in the fields of metalworking, ore extraction, surface treatment, washing and cleaning, cosmetics, medicine and foodstuff processing and preparation.
