Review on Nanoemulsions Production and Comparison of Homogenizers Efficiencies

Producing emulsions with nanometric drop size distribution has been considered recently in pharmaceutical, chemical, polymerization and food industries in order to improve quality and shelf life of emulsions. Also, the recently manufactured homogenizers that provide high pressures over 3500 bar (i.e. over 30 times the pressure of common homogenizer) supply the production of nanoemulsions. In this paper, studying the various homogenizer efficiency based on the results presented in literatures, showed that high pressure homogenizers like microfluidizer are so suitable option for producing nanoemulsions.
