Résumé : The phase behavior of the system comprising the cationic surfactant Cetylpyridinium chloride, the co-surfactant Hexanol, the polyelectrolyte polyacrylic acid (PAA) and the solvent, at pH=12 was investigated. For our experimental study, we observe that the phase behavior of our system presents the points in which we have the biphasic. Since we interest by the lamellar phase, after we obtained the diagram with varied ϕ and Ψ we observe how the interval of the lamellar phase change in each medium specifically in each value of ϕ and Ψ.
