Abstract

Background and purpose: Emulsion are the systems developed from due ho minimal distribution of a non liquid in onoter liquid and in contrast to micro EMULSIONS, stabilized are non strabilized. Their stability can be increased by increasing surface active agents. Since the amount og surfactant being used and volumic percentage of oil phase can effect the properties of wmulsion. This study was designed in order to evaluate the effect of oil phase and mixture of SURFACTANTS on critical HBL oil phase and reolegic behavier of liquid parafine emulsion in waterMaterials and methods. In order to evaluate effect of oil phase, emulision containing 25-55% oil phase and 5% mixture of SURFACTANTS in HBL range of 7-12 were prepared. For evaluation of effect on the rate of SURFACTANTS in oil emulsion containing 25% oilphase, 0.75 to 5% of SURFACTANTS mixture was prepared. Rate of physical stability of expected EMULSIONS were evaluated at room temperature, 4°c and 40°c Results: The results indicted that, with increasing in rate of internal phase at constant concentration of surfactant, stability of EMULSIONS decrease (P<0.01). Also with increase in the rate of surfactant to a certain extent. Stability of EMULSIONS at constant concentration of internal phase increase. This phenomenon seams to be due to formation of a preper and stable film of surfactant around the surpending dispersed phase dropets and increase the physical stability at proper concetration of surfactant, vis cosity increases by increasing in the amount of dispersed phase.Conclusion: Considering the abtained results, it can be said that for pereperation of stable emulsion of liquid paraphine in water there is need of a proper concentration of internal phase increase in intrnal phase with and emulsifier with optimum HLB. and making constant of emulsion concentration, rate of stability of the emulsiofier also decrease, which can be probably due to inefficiency of SURFACTANTS to to form a proper film around the sadpending dispersed phase droplets. About the effect on change of the mentioned factors on the apparent viscogity it can be said that increase in the rate internal phase leads to increase in apparent viscosity of emulsion.
