TI  - Mixed micelles of series of monomeric and dimeric cationic, zwitterionic, and 
      unequal twin-tail cationic surfactants with sugar surfactants: a fluorescence 
      study.
PG  - 551-9
AB  - Steady state fluorescence measurements have been carried out for binary mixtures 
      of a series of monomeric cationic (MC), zwitterionic (ZI), dimeric cationic (DC), 
      and twin-tail cationic (TC) surfactants with sugar (beta-C8G and beta-C12G) over 
      the whole mole fraction range using pyrene as fluorescence probe. The cmc values 
      thus determined for all the binary mixtures have been further evaluated using the 
      regular solution theory. The various micellar parameters, such as micelle mole 
      fraction (X1), regular solution interaction parameter (beta), micropolarity, and 
      mean micelle aggregation number (Nagg), have been determined for all these series 
      of mixtures. Variation in all these micellar parameters demonstrates that mixed 
      micelles of these surfactants with beta-C8G are mostly synergistic in nature and 
      the synergism increases with the increase in hydrophobicity of the cosurfactant 
      in each case. The mixtures of beta-C12G with various cosurfactants do not show 
      this behavior and instead of it, they show an increase in antagonism with the 
      increase in hydrophobicity of cosurfactants. This discrepancy has been attributed 
      to a large difference in hydrophobicity between beta-C8G and beta-C12G, and the 
      chain folding of the latter is considered to be the reason for the antagonism.
