Emulgels are emulsion system, either of the oil-in-water or water in-oil type, which are gelled by mixing with a gelling agent. Both oil-in-water and water-in-oil emulsions are extensively used for their therapeutic properties and as vehicles to deliver various drugs to the skin. Emulsions possess a certain degree of elegance and are easily washed off whenever desired. In addition, the formulator can control the viscosity, appearance, and degree of greasiness of cosmetic or dermatological emulsions. Gels for dermatological use have several favorable properties such as being thixotropic, greaseless, easily spreadable, easily removable, emollient, non staining, compatible with several excipients, and water-soluble or miscible. Gellifying the emulsion increases the viscosity of the emulsion and also its stability. The emulsion-based gel have great potential for topical drug delivery.
