AB  - The interaction of anionic surface active agents e.g. sodium decyl sulphate 
      (SDS), sodium dodecyl sulphate (SDDS), sodium tetradecyl sulphate (STDS), sodium 
      hexadecyl sulphate (DHDS) and sodium octadecyl sulphate (DODS) with cationic 
      dyes, methylene blue (MB), crystal violet (CV) acridine orange (AO), rhodamine 6G 
      (Rh 6G) and quinacrine dihydrochloride (QD) has been studied in three regions by 
      conductometric titration. In the first region ion pair association occurs and the 
      species (cationic and anionic) exist in equilibrium with homogeneous solution. In 
      the second region complexation occurs by 1:1 with MB, CV and AO and by 2:1 with 
      QD and Rh 6G forming a heterogeneousphase, separation and equilibration 
      containing free ions and ion-pair. In the third region the micelle formation 
      occurs by the excess of anions in the presence of cations as well as ion-pair 
      formation and separated complex ions that give solubilization of the complex to a 
      homogeneous clear solution.
