Abstract

- Alkylamide di-N-oxide derivatives represent a new class of dicephalic amphoteric surfactants exhibiting profound surface properties.
- Aggregation behavior of Cn-MEDA's at free surface or in bulk at physiological pH was studied by means of interfacial tensiometry, EPR and DLS.
- Structural properties of Cn-MEDA's were performed on the theoretical basis by employing in silico techniques (DFT and QSAR).
