Abstract

The invention concerns amphiphilic compounds of general formula (I), in which R.sup.1 and R.sup.3 each represent a C.sub.1 -C.sub.22 hydrocarbon residue, R.sup.2 is a spacer and X and Y are functional groups. The proposed compounds have at least two hydrophilic and at least two hydrophobic groups based on dicarboxylic acid diamides. The amphiphilic compounds according to the invention are mostly surface-active and are especially suitable for use as emulsifiers, demulsifies, 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.
