Reaction of adducts of dissymmetric N,N-dimethylhydrasine and ethylenoxide with methylesters of carbonic acids has been analyzed. N(N,N-dimethyl-N-hydroxyethyl) imides of higher carbonic acids, obtained by this reaction, are effective surface active substances. Their surface activity and micelle formation in aqueous solutions have been investigated.
