Abstract

The invention relates to amphiphilic compounds of the general formula (I) with at least two hydrophilic and at least two hydrophobic groups based on di, oligo or polyolethers. The amphiphilic compounds of this invention are highly surface active and are suitable as emulsifiers, demulsifiers, detergents, dispersants and hydrotropes for industrial and domestic purposes, e.g. in the fields of metalworking, ore separation, surface treatment, washing and cleaning, cosmetics, medicine and food processing and preparation.
