Abstract

The invention concerns amphiphilic compounds of general formula (I) ##STR1## with at least two hydrophilic and at least two hydrophobic groups based on diacarboxylic acid diamides. The amphiphilic compounds according to the invention are mostly surface-active and are suitable for use as emulsifiers, demulsifiers, detergents, dispergents and hydrotropic agents in industry and households, for example, in the treatment of metals, ore processing, surface finishing, washing, cleaning, cosmetics, medicine and food processing and preparation.
