Description
2-Butoxyethanol CP (CAS: 111-76-2), also commonly referred to as Ethylene Glycol Monobutyl Ether (EGMBE) or Butyl Cellosolve, is a high-purity, versatile glycol ether liquid. Designated as Chemically Pure (CP) Grade, this product is refined to meet stringent quality standards suitable for specialized industrial processing, laboratory formulations, and high-performance commercial applications requiring low impurity levels.
It is widely recognized across industries under several major commercial trade names, including Butyl CELLOSOLVE™ (Dow Chemical), Butyl Icinol, Ektasolve™ EB (Eastman Chemical), and Eastman™ EB Solvent.
Key Performance Features & Benefits
Exceptional Solvency: Features an amphiphilic molecular structure containing both ether and hydroxyl functional groups, enabling it to dissolve a vast range of hydrophilic (water-soluble) and hydrophobic (oil-soluble) substances.
Effective Coupling Agent: Acts as a powerful mutual solvent and coupling agent, facilitating the blending of immiscible liquids, water-borne coatings, and complex surfactant formulations.
Flow & Levelling Enhancer: Improves surface wetting, gloss, and levelling properties in industrial paints, varnishes, lacquers, and water-based printing inks.
High-Efficiency Degreaser: Penetrates, dissolves, and lifts heavy oils, grease, lipids, and synthetic soils rapidly, making it a staple raw material in heavy-duty cleaners.
