ABSTRACT

Microemulsion gels are hybrid systems that combine the properties of both microemulsions and gels, offering unique advantages in various industrial and biomedical applications. A microemulsion gel is typically composed of water, oil, surfactants, and co-surfactants, forming a stable, transparent, and thermodynamically stable system. By incorporating gelling agents into a microemulsion, the viscosity of the system is increased, resulting in a gel-like consistency. These gels exhibit distinctive characteristics such as controlled release, improved stability, and enhanced drug delivery efficiency. Due to their biocompatibility, ease of formulation, and versatility, microemulsion gels have gained significant interest in fields like pharmaceuticals, cosmetics, food products, and topical therapies. This review focused on the preparation methods, advantages, potential applications and various evaluation parameters of microemulsion gels.
