Overview of Nanoemulsion Preparation Methods, Characterization Techniques and Applications

Basically Emulsions are liquid–liquid dispersions along with one liquid phase which is dispersed in the other liquid phase as small sized droplets. These days, there is an increasing interest in the utilization of nano emulsions in pharmaceuticals as well as cosmetics industry because of it’ snumerous of potential advantages over conventional and microemulsions. Nanoemulsions are nano-sized emulsions which have sizes range from tens to hundreds of nano meters. Nano emulsion sex hibit useful characteristics due to its small droplet size which leads to high surface area per unit volume, higher stability, optically transparent appearance, flexible fluidity as well as increased bioavailability of lipophilic components. The current review provides a comprehensive overview, starting with an introduction of nano emulsion types, preparation methods, stability study, characterisation, and applications of nano emulsion.
