A REVIEW ON EMULGEL

Emulgels have emerged as one of the most interesting topical drug delivery systems as it has dual release control i.e. emulsion and gel. The developed emulgels were evaluated for their physicochemical properties like colour, homogeneity, consistency, spreadability, pH value, rheological behaviour, drug content, drug release and stability. They are generally adopted for the purpose as antiseptics, antifungal agents, skin emollients, and protective. The activity of topical preparation reveal the various factors as drug solubility, contact time to skin, its lipophilicity, its permeability. Gels are a quite newer class of dosage form formulated by entrapment of large amounts of aqueous or hydro-alcoholic liquid with in the network of colloidal solid particles. Gel formulations generally provide faster drug release as compared to conventional topical drug delivery formulations. In spite of many advantages of gels, a major limitation is in the difficulty in delivery of hydrophobic drugs. So to overcome these limitations, emulgels are prepared. Emulgel are being used for the delivery of analgesics, anti-inflammatory, anti-fungal, anti-acne drugs and various cosmetic formulations with still wide range to explore.
