Nano emulsion: formulation technique and Application

Abstract

Nanoscale emulsions have sparked a lot of attention in recent decades due to their unique characteristics such as high consistency, beautiful appearance, excellent performance, and sensory benefit. Nanoemulsion are, in fact, one of the most widely used formulation techniques in the pharmaceutical and cosmeceutical industries. Nanoemulsion' fast growth as a method for delivering bioactive substances/drugs in cosmetics and dermatological treatments has been fuelled by their thermodynamic and kinetic stability, as well as their minute droplet size. The quality of Nano emulsions is largely determined by their composition and production process. They are primarily aimed at high performance, consumer product distribution, and the possibility of mass manufacturing. However, formulators encounter several constraints, particularly when it comes to the dispersion of active substances into human skin. The common procedures utilised by formulators to create Nano emulsions as final application products for cosmeceutical applications have been described in this study. This study also includes an overview of characterisation tools for distinguishing among micro and Nano emulsions, as well as their standards in terms of the physical and thermodynamic stability.
