Formulation and Characterization of Nano Emulsion from Limolina Acidessima

Abstract

An emulsion is an opaque, heterogeneous system made up of two immiscible liquid phases, usually oil and water, with one phase scattered throughout the other as microscopic or colloidal-sized droplets. These systems display the characteristic traits of metastable colloids, such as Brownian motion, reversible phase changes caused by droplet interactions, and irreversible transitions resulting in emulsion disintegration. Emulsifiers—surfactants that reduce interfacial tension and can form structured interfaces—help to form and stabilize emulsions. Emulsions have a wide spectrum of internal dynamics and mechanical properties, which change considerably with dilution or concentration. Their ability to disperse hydrophobic substances in a continuous aqueous phase makes them useful in a variety of applications, including painting, road surfacing, lubrication, and paper coating, where they also help eliminate the need for organic solvents by allowing for the homogeneous mixing of immiscible fluids. Emulsions are essential in a variety of industries, including food, cosmetics, medicines, and petroleum, allowing the development of new products and procedures that would otherwise be impossible. To achieve the intended functionality and stability in emulsions, variables such as emulsifier selection, droplet size and distribution, and ambient conditions must be carefully controlled
