Rheological properties of primary pharmaceutical emulsions obtained by homogenization

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

Rheological investigations of pharmaceutical emulsions prepared with modified lecithin

In this paper the results of rheological investigations of pharmaceutical microemulsions prepared using modern lecithine derived emulsifiers has been prevented out. High stability of obtained systems and wide possibilities of controlling rheological parameters were found
