A Review on Nanoemulsion

Nanoemulsions are submicron-sized colloidal dispersions composed of two immiscible liquids stabilized by surfactants. With droplet sizes typically ranging from 20 to 200 nm, nanoemulsion have attracted significant attention in pharmaceuticals, cosmetics, food, and agricultural industries due to their high kinetic stability, optical transparency, and enhanced bioavailability of encapsulated compounds. This review summarizes the composition, methods of preparation, characterization techniques, advantages, and applications of nanoemulsions, along with recent advancements and challenges in their development.
