Nano Emulsion Drug Delivery System: A Review

Abstract

Abstract: In nanoemulsions, both oil and water droplets are stabilised by an amphiphilic surfactant. Ultrafine dispersions with varying drug loading, viscoelastic properties, and aesthetic characteristics may be useful for the administration of medication. A 20-500-nanometer droplet size range for nanoemulsions has been established. The biological behavior of a nanoemulsions formulation is heavily influenced by its droplet diameter and surface properties. Small droplet size results in clear emulsions; therefore, the appearance of the product is unaffected even by the addition of an oil phase. Nanoemulsions are oil-in-water dispersions that are transparent or translucent and are stabi-lized by an interfacial layer of surfactants and cosurfactant particles with droplet size smaller than 100 nm. New nanoscience-based technologies are becoming increasingly popular as a means of im-proving food safety, quality, and nutrition. In this field, nanoemulsions have been a key focus since they can be readily manufactured using current food components and technology. Food nanoemul-sions, which are tiny oil droplets distributed in water, are being used as delivery methods for a vari-ety of hydrophobic compounds, including nutrients, nutraceuticals, antioxidants, and antimicrobial agents. The present review is focused on the formulation, characterization, and applications of nanoemulsions.
