【 摘 要 】

For the constructionof the phase diagrams, the method of the aqueous titration was used. There wereprepared 5 ternary diagrams, varying the surfactant and the oil phase. The liquid-crystallinephases were identified by polarized light microscopy. The formulations preparedwith silicon glycol copolymer, polyether functional siloxane (PFS) and water(S1) and with diisopropyl adipate, PFS and water (S4)presented liquid-crystalline phases with lamellar arrangement. Moreover, after15 days in hot oven (37 ºC), the formulations presented hexagonal arrangement,evidencing the influence of the temperature in the organization of the system.
