- This study presents a novel Natural Deep Eutectic Solvent (NADES) based on Calcium Chloride Dihydrate (CaCl2.2H2O) and glycerin, exploring its synthesis, thermophysical characterization, and potential applications. The thermophysical properties, including density, pH, surface tension, refractive index, and viscosity, were systematically investigated. Fourier Transform Infrared (FTIR) analysis provided insights into the molecular composition, revealing the formation of new bonds within the NADES structure. Thermogravimetric Analysis (TGA) indicated significant weight loss post-200°C, primarily attributed to glycerin degradation. The non-linear decrease in surface tension, refractive index, and viscosity with temperature highlights the versatility of CaCl2.2H2O -NADES for applications in various industries. Potential areas of application encompass pharmaceuticals, biotechnology, optics, coatings, thermal energy storage, environmental remediation, the food industry, electrochemical systems, material synthesis, and agrochemicals. The eco-friendly and low-toxicity nature of NADES positions them as promising, sustainable alternatives. However, further research and development are essential to optimize their performance and tailor properties for specific industrial needs.
