Role of Polymers as Gelling Agents in the Formulation of Emulgels

Madhavi latha Samala and Gowripattapu Sridevi

 Gels are new magnificence of semisolid estimation outlines made by ensnarement of tremendous degree of liquid and hydro-alcoholic liquid in an association with colloid stable particles like inorganic materials or common polymers of made origin or trademark. The use of novel semisolid Gels measurements has reached out in both pharmaceutical industry and cosmetics nowadays. However, gels are having many advantages of better patient compliance, avoiding first pass effect which is major drawback in delivery of hydrophobic drugs and less interaction with food and drugs. Apart from this confinement, another procedure in light of emulsion device have risen i.e., Emulgels. Different kinds of polymers are used nowadays which are performing multiple works basically as emulsifiers and thickeners. The new gelling polymers have the ability of gelation that is useful in the formulation of stable systems by decreasing the surfacial and interfacial tension, thereby increasing the viscosity of the liquid phase. In this process, the gelling administrators circuit into water stage changes over the emulsion into stable formulation of emulgel. Emulgel are basically emulsions that may be oil-in-water or water-in-oil type gets jellified which when blended with gelling agents. Emulgels acts as excellent medium for water insoluble tablets or hydrophobic tablets. Emulgel are generally used when the other forms of prescription drugs fails to respect cutaneous disorders for instance, psoriasis, and parasitic skin break out, defilements particularly. Emulgel has become important I n the field of pharmaceutical semisolid preparations.
