Abstract

Nanoemulsions are submicron sized emulsion that is under extensive investigation as drug carriers for improving the delivery of therapeutic agents. Nanoemulsion as a part of multiphase colloidal dispersion, is a heterogeneous system composed of fine oil in water or water in oil dispersion with surfactant and co-surfactant having droplets covering the size range of 20-600 nm and show narrow size distribution. These are prepared using high energy emulsification method including microfluidic and ultrasonic methods, which rupture large micro droplets into nanoscale droplets provides useful non equilibrium system of structured liquids. Thus the aim of this review is focused on nano emulison advantage and disadvantage, various methods of preparation, characterization techniques and the various applications of sub micron size emulsion in different areas such as various route of administration, in chemotherapy, in cosmetic, etc.
