Description

9-Octadecenoic Acid (9Z)-, 2-Decyltetradecyl Ester is a high-purity, long-chain fatty acid ester derived from oleic acid. This compound serves as a versatile and effective non-polar intermediate and emollient in advanced formulations. It is particularly valuable for industries requiring stable, lipophilic components with excellent spreading and conditioning properties. Key sectors include specialty lubricants, high-end personal care, and performance polymer additives.

Application

• Lubricant & Grease Additive: Acts as a friction modifier and viscosity index improver in synthetic lubricants and high-temperature greases.
• Personal Care Emollient: Used in premium skincare, sun care, and color cosmetics for its non-greasy, smooth skin feel and excellent spreading characteristics.
• Polymer Plasticizer: Functions as a secondary plasticizer and processing aid to improve flexibility and workability in PVC and other polymer systems.
• Metalworking Fluid Component: Incorporated into formulations for drawing, stamping, and cutting oils to provide lubrication and surface finish.
• Textile & Leather Auxiliary: Serves as a softening agent and water-repellent finish for fibers, fabrics, and leather goods.
• Industrial Coating Additive: Enhances flow, leveling, and substrate wetting in solvent-based coatings and inks.
