Nano Emulsion: A Novel Platform for Novel Drug Delivery System

Nano emulsion is an ideal system. Nano emulsion is defined as the thermodynamically stable, isotropically clear dispersion of two immiscible liquids such as oil and water stabilized by film of surfactant. It is retended into several dosage form like creams, aerosols, foams, oral, intranasal, pulmonary, the droplet size of Nano emulsion is in the range of 20-200nm. Emulsion and Nano emulsion are differentiated by their size mainly. Nano emulsion is now an focused topic in dosage form, designing and pharmacotherapy. Their small size leads to useful properties such as high surface area per unit volume, optically transparent appearance.
