Objectives Tolnaftate (TOL) is used as a topical antifungal agent but has poor skin penetration. Therefore, the present study is designed to formulate an ethosomal gel of TOL to enhance drug penetration through the skin. Methods Using the cold method ethosomal formulations with different concentrations of ethanol and soy phosphatidylcholine (SPC) were formulated. The formulation of ethosomes was characterized by vesicle size, polydispersity index and zeta potential, % drug entrapment efficiency (EE), and scanning electron microscopy (SEM). The optimized ethosomal formula was incorporated in a 1% Carbopol hydrogel dosage. Evaluation of in vitro penetration of prepared gel was performed on goat skin using Franz diffusion cells and compared with conventional gel. Result The ethosomal formulation EF5 showed the highest % EE (76.82%) with a small vesicle size of 210.1 nm and was selected as the optimized formulation. The SEM result shows that the vesicles were spherical, smooth, and in the 200-nm range. In vitro, permeability study shows that steady-state flux of TOL from ethosomal and conventional gels were 6.667 and 3.685 µg/cm/h, respectively (p < 0.001). It indicated that the flux of Ethosomal hydrogel (EHG) is 2.0-fold higher than conventional hydrogel (CHG); this may be due to the flexible nature of ethosomes and ethosomal core containing ethanol, which dissolves the lipid bilayer of skin and overcomes the barrier. In vitro, an antifungal study shows that the incorporation of TOL in ethosomal hydrogel retains their activity. Conclusion From the results, it was concluded that TOL topical ethosomal gel for antifungal activity will possibly be a good choice.

“…However, some studies have explored thermal storage units and cooker construction [7]. Economic implications of solar cooking systems have also been studied in particular regions, like Lebanon [5] and India [8]. However, existing research tends to focus on end uses rather than conducting comprehensive development and experimental analysis under specific local climatic conditions.…”

Indian villages use wood, cow-buffalo dung cakes, and agricultural waste for cooking, while urban areas use piped natural gas and LPG. Desertification and rising fuel prices require renewable energy sources like solar energy. Three types of solar cookers are used for cooking like: box, concentrator, and indirect. The box solar cooker, popular for over two centuries, uses solar radiation to generate heat energy for cooking food. It can be powered by reflector sheets and energy-storing materials, with a 35.3-21.7 % energy efficiency compared to a standard cooker with 27.6-16.9%. Direct solar cookers with parabolic reflectors concentrate reflected energy, suitable for direct or indirect cooking. In winter, a parabolic dish solar cooker cooks at a faster pace and higher temperatures. Moreover, the Parabolic Trough Collector offers a more practical cooking solution. This research work evaluates the efficiency of the Parabolic Trough Collector (PTC) in various real-world climatic conditions using locally available materials for reflector having 97 % of reflectivity and absorber tube made-up of copper tube covered with black colour sheet. Cooking system efficiency was tested, and the results ranged from 5 to 40%. Further, this study aims to identify an applied performance evaluation in Gujarat, India.
