Thermal, Mechanical and Electrochemical Characterization of Gelatin-Based Physical Emulgels

The present study reports the development of gelatin based physical emulgels (EHs). Emulgels were prepared using gelatin and mustard oil. The emulgels were characterized thoroughly by microscopy, FTIR (fourier transform infrared) spectroscopy, DSC (Differential scanning calorimetry), mechanical studies and impedance spectroscopy. The microscopic results suggested unimodal size distribution of the oil droplets. Thermal, mechanical and electrical properties of the emulgels showed composition dependent properties. Ciprofloxacin was used as the model drug. The release kinetics of the drug followed anomalous release behavior and showed good antimicrobial activity. The emulgels were hemocompatible and showed pHs within the physiological limits
