Description

9-Octadecenoic Acid 2-(Octadecyloxy)Ethyl Ester is a high-purity, long-chain fatty acid ester derivative, valued for its excellent lubricity, stability, and hydrophobic properties. This compound serves as a versatile intermediate and functional additive, enabling enhanced performance in demanding formulations. It is essential for manufacturers in the lubricants, plastics, coatings, and personal care industries seeking to improve product texture, release properties, and surface modification.

Application

• Lubricant & Grease Additive: Functions as a friction modifier and viscosity improver in synthetic and semi-synthetic lubricants.
• Plastic & Rubber Processing Aid: Acts as an internal and external lubricant and mold release agent in polymer compounding and extrusion.
• Coating & Ink Formulation: Imparts water repellency, leveling, and slip properties to industrial paints, varnishes, and printing inks.
• Personal Care & Cosmetics: Used as an emollient and thickening agent in creams, lotions, and stick formulations for a smooth skin feel.
• Textile & Fiber Treatment: Serves as a softening agent and water-repellent finish for synthetic and natural fibers.
• Metalworking Fluids: Incorporated as a lubricity additive and corrosion inhibitor in cutting and drawing oils.
