Resumo
DEVELOPMENT of LIQUID-CRYSTALLINE SYSTEMS USING SILICON GLYCOL COPOLYMER and POLYETHER FUNCTIONAL SILOXANE. For the construction of the phase diagrams, the method of the aqueous titration was used. There were prepared 5 ternary diagrams, varying the surfactant and the oil phase. The liquid-crystalline phases were identified by polarized light microscopy. The formulations prepared with silicon glycol copolymer, polyether functional siloxane (PFS) and water (S(1)) and with diisopropyl adipate, PFS and water (S(4)) presented liquid-crystalline phases with lamellar arrangement. Moreover, after 15 days in hot oven (37 degrees C), the formulations presented hexagonal arrangement, evidencing the influence of the temperature in the organization of the system.
