In the past few years, new efforts have been devoted to the study of the interfacial film of amphiphilic molecules because of the increasing interest for new phases: microemulsions[1] and lyotropic nematics[2]. Among the amphiphiles, non-ionic surfactants[3] have been particularly studied because of several special features:
  • they are commercially available in a very pure form

  • their aqueous micellar solutions exhibit a lower consolute point whose nature is not completely understood[4–7].

  • they are able to form microemulsions without cosurfactant[8] in contrast to ionic surfactants. This capability seems to be correlated with the extension of the lamellar phase in the phase composition diagram.
