Rheological properties of primary pharmaceutical emulsions obtained by homogenization

Abstract

The paper presents the results of rheological examinations of primary emulsions with the potential for pharmaceutical applications, created through emulsification using a homogeniser. The water phase of the examined emulsions was made up of water solutions of hydrocolloids, the fatty phase was the pharmaceutical oil Miglyol 812N and canola oil, sunflower seed oil, olive oil. For the determination of relations between the structural parameters of the emulsions and their viscous properties flow curves and viscosity curves were obtained for the examined systems. The obtained results were processed through regression of experimental points by rheological equations, using the own software of the rheometer.
