Product Overview

Ethyl Acetate (EAC) is a versatile ester solvent derived from the esterification of acetic acid with ethanol. Renowned for its low toxicity, pleasant fruity aroma, and rapid evaporation rate, EAC is a preferred solvent in various industrial applications. Its excellent solvency power and low environmental impact make it a staple in coatings, adhesives, pharmaceuticals, and analytical chemistry.

Key Applications

1. Coatings and Paints

  • Solvent for Nitrocellulose and Cellulose Esters: EAC is employed in the formulation of nitrocellulose lacquers and cellulose acetate coatings, providing fast drying times and excellent film formation.

  • Industrial Coatings: Utilized in coatings for metal, wood, and plastic surfaces to enhance durability and resistance to environmental factors.

  • Varnishes and Wood Finishes: Applied in varnishes and wood coatings to improve surface properties and appearance.

2. Adhesives and Sealants

  • Pressure-Sensitive Adhesives (PSAs): EAC-based adhesives offer strong initial tack and long-term adhesion, suitable for labels, tapes, and packaging materials.

  • Construction Sealants: Used in sealants for construction applications, providing flexibility and resistance to environmental factors.

3. Pharmaceuticals and Food Industry

  • Extraction Solvent: EAC is employed as an extraction solvent in the pharmaceutical industry for the isolation of active compounds from natural sources.

  • Decaffeination Agent: Utilized in the decaffeination process of coffee beans and tea leaves, preserving flavor while removing caffeine.

  • Flavoring Agent: Naturally occurring in fruits like bananas and apples, EAC is used as a flavoring agent in the food industry to impart fruity notes to products such as candies and beverages.

4. Analytical Chemistry

  • Chromatography: EAC is a common solvent in column and thin-layer chromatography, effectively separating compounds due to its moderate polarity.

  • Extraction and Purification: Serves as a solvent in the extraction and purification of analytes from complex matrices such as biological fluids and environmental samples.

5. Cosmetics and Personal Care

  • Nail Care Products: EAC is a key ingredient in nail polish removers and base coats, effectively dissolving nitrocellulose and other components.

  • Fragrance Carrier: Used in perfumes and air fresheners for its ability to evaporate quickly, leaving the scent without oily residues.
