Microemulsions are thermodynamically stable, isotropic liquid mixtures of oil, water, and surfactant, often with a cosurfactant. They are characterized by their ability to form spontaneously and their small droplet size, typically in the range of 10 to 100 nanometers, which gives them unique properties compared to conventional emulsions.

Microemulsion

Microemulsions are thermodynamically stable, isotropic liquid mixtures of oil, water, and surfactant, often with a cosurfactant, that form spontaneously and have unique properties such as low interfacial tension and high solubilization capacity. They are utilized in various fields, including pharmaceuticals, cosmetics, and enhanced oil recovery, due to their ability to improve the delivery and stability of active ingredients.

Oil and water

Surfactants are compounds that lower the surface tension between two liquids or between a liquid and a solid, playing a crucial role in processes like emulsification, detergency, and wetting. They consist of a hydrophilic head and a hydrophobic tail, allowing them to interface between polar and non-polar substances effectively.

Surfactant

A cosurfactant is a substance that, when used alongside a surfactant, enhances the efficacy of the surfactant in reducing surface or interfacial tension. It is often used to stabilize emulsions, improve solubilization, and modify the properties of surfactant systems in various industrial and pharmaceutical applications.
