A gel is colloid that is typically 99% by weight liquid. Gels are defined as a substantially dilute cross-linked system, which exhibits no flow when in the steady-state. A major limitation is in the delivery of hydrophobic drugs. To overcome the limitation a novel approach i.e. an emulsion based approach is being used so that even a hydrophobic moiety can enjoy the unique properties of gels. When gel and emulsion are used in combined form the dosage form are referred as emulgel. Emulgels have emerged as one of the most interesting topical delivery system as it has dual release control system i.e. gel and emulsion. The presence of a gelling agent in the water phase converts a classical emulsion into an emulgel. Emulgels for dermatological use have several favorable properties such as being thixotropic, greaseless, easily spreadable, easily removable, emollient, non staining, water-soluble, longer shelf life, bio-friendly, transparent and pleasing appearance. The use of emulgel can be extended in analgesics and antifungal drugs.
