Abstract Nanotechnology has become a wide range in the field of pharmaceutical sciences, which has an effect on various drug delivery research from the last ten years. The developed technology is being explored for the better therapeutic performance of drugs by enhancing the solubility of water-hating drugs (hydrophobic drugs), increasing permeability, regulating the drug disposition and biodistribution and by permitting the targeted delivery of drugs.1 The nanotechnology is broadly categorized into drug nanoparticles or nanosuspension, nanocarriers like lipids, polymeric, inorganic nano-carriers, as these nano-carriers involve liposomes, microemulsions, nanoemulsions, lipid core micelles, solid lipid nanoparticles which are used for the targeted drug delivery systems.2 Based on this technology the drug components which have poor aqueous solubility, permeability, bioavailability and due to instability in physiological medium, the nanoemulsions are selected to enhance the properties.3 Nanoemulsions are group of heterogeneous with two immiscible liquids as o/w or w/o with droplet size ranges between 20 to 200nm after the method preparation, before the term nanoemulsions these are termed as mini-emulsions, micro-emulsions, submicron emulsions and ultrafine emulsion due to unclear emulsions based on their size of the particles present, so to overcome the confusion in identifying the actual term, the size of the particles which are within the limits or in range and also the main factor is the emulsion which is indicating transparent are termed as nanoemulsions and which are slightly different are called as microemulsions.4-7
