Description

2-[2-(2-Hydroxyethoxy)Ethoxy]Ethyl Octanoate is a high-purity, non-ionic ester compound valued for its excellent solvency, low volatility, and compatibility with a wide range of polymers and resins. Its unique structure provides effective plasticizing and coupling properties, making it a versatile intermediate and functional additive. This chemical is essential for formulators and manufacturers in the personal care, coatings, and specialty chemical industries seeking to enhance product performance and stability.

Application

• Plasticizer & Solvent: Acts as a co-plasticizer and solvent in polymer systems, including PVC, cellulose esters, and synthetic resins, improving flexibility and processability.
• Personal Care & Cosmetics: Used as an emollient, skin-conditioning agent, and carrier in formulations for creams, lotions, and sunscreens due to its smooth texture and low irritation potential.
• Lubricants & Functional Fluids: Serves as a base or additive in synthetic lubricants, metalworking fluids, and hydraulic fluids, offering good thermal stability and lubricity.
• Chemical Intermediate: Employed in the synthesis of more complex esters, surfactants, and specialty chemicals where its ethoxylated chain provides desired hydrophilicity.
• Coatings & Inks: Functions as a coalescing agent and plasticizer in water-based and solvent-based coatings, adhesives, and printing inks to enhance film formation and durability.
• Industrial Cleaners: Utilized as a coupling agent and degreaser in industrial and institutional cleaning formulations for its solvating power.
