Highly sustainable emulgels loaded with Annona squamosa L. extract with and without penetration enhancer were formulated. Characterization evaluations of prepared emulgels formulations were done at various storage conditions. Acetone (70%) was used to prepare Annona squamosa L. extract by using maceration technique. Emulgels were prepared by using 4% extract with and without penetration enhancer (clove oil 8%). Varying concentrations of carbapol 940 (0.5-2%) were used in the development of emulgels. All the formulations were kept first at 25°C and then stressed at 40°C to sort out the most stable formulation. The in vitro characterization of the optimized formulation was done including pH, conductivity, phase separation, and mean droplet size. These parameters were monitoring over a period of 90 days at 8°C, 25°C, 40°C and 40°C with 75 % RH.
