  • Applications

    Ethanol (CAS 64-17-5) is a versatile solvent and processing aid used across multiple industries. In pharmaceuticals and cosmetics/personal care, it serves as a solvent and extraction medium for active ingredients, fragrance compounds, and formulation components. It is widely employed in cleaning and disinfection applications, including surface sanitizers and wipe formulations. In the food and beverage sector, ethanol is the principal product of fermentation and is also used as a solvent for extracting flavors and colorants. As a renewable fuel, it serves as a biofuel or blending component in gasoline. In coatings, inks, and polymer processing, ethanol acts as a solvent for resins and as a processing aid in formulations, helping achieve desired rheology and drying characteristics.
