Influence of the oleic phase and co-surfactant addition in non-ionic microemulsified systems

Microemulsion is a thermodynamically stable dispersion consisting of an aqueous and organic phases, both stabilized by surfactant molecules when in need, co-active surfactant. The nature structure these components are essential the formulation microemulsified systems. For this, construction phase diagrams can be fundamental tool to characterize ideal experimental conditions for existence operation microemulsions. Thus, present work had as objective obtain comparison between microemulsions with different compositions through ternary diagrams, aiming achieve most system. To produce systems, non-ionic (Ultranex NP 60), co-surfactant (Isopropyl Alcohol), two phases (pine oil castor oil) (glycerin solution) were used. Also complementing study, rheological tests oleic accomplished, well their thermogravimetric analysis. focus reached was find system largest Winsor type IV region (microemulsion). It verified this significant increase addition medium using vegetable oil, such pine since it promotes strong surfactant-oil interactions on interface.
