Abstract

The invention relates to amphiphilic compounds of the general formula I ##STR1## which have at least two hydrophilic and at least two hydrophobic groups and are based on carbonic acid derivatives. The spacer A is an aliphatic, cyclic or acyclic or an aromatic di-, oligo- or polycarbonate of the formula II: ##STR2## The amphiphilic compounds according to this invention are mostly surface-active and are suitable as emulsifiers, demulsifiers, detergents, dispersants and hydrotropes for industrial and domestic use, in particular in the fields of metalworking, ore extraction, surface finishing, plastics processing, washing and cleaning, cleaning of hard surfaces, manual dishwashing compositions, cosmetics, medicine and food processing and preparation.
