Nanoemulsion: Formulation Techniques, Evaluation, Characterization And Application

Abstract

This article provides a brief overview of the preparation process and evaluation of nano emulsions as drug
carriers for enhancing therapeutic agent delivery. For the preparation of nanoemulsions, several techniques
such as micro fluidization, high-pressure homogenization, low energy emulsification, and solvent evaporation
method and parameters such as droplet size analysis, viscosity determination, drug content, refractive index,
pH, zeta potential, Transmission electron microscopy, thermal stability, release, and in vitro skin permeation
study will be used. As a result, the focus of this review is on the advantages of nanoemulsions, various methods
of preparation, characterization techniques, and the various applications of sub-micron size emulsion in various
areas such as various routes of administration, chemotherapy, cosmetics, and so on.
