The interaction of dye-surfactant mixtures have been examined by the absorption spectroscopy. The interaction of surfactant mixtures and the CMC exchange of surfactant mixtures are examined. In dye (Thionin)-anionic surfactant(SDS) system, the absorption band of dimer increased at S/D ≤ 100. In Thionin-SDS-AE system, the change of dimer, monomer and oligomer band was influenced the CMC of AE. In various temperature, the interaction between Dye and Surfactant mixtures are examined.
