Description

9-Octylheptadecanoic Acid Methyl Ester is a high-purity, long-chain fatty acid methyl ester (FAME) derived from specific synthetic or natural sources. This compound serves as a versatile intermediate and functional additive, valued for its hydrophobic properties and chemical stability. It is primarily utilized by manufacturers in the lubricants, plasticizers, surfactants, and personal care industries seeking to enhance product performance.

Application

• Lubricant & Grease Formulation: Acts as a synthetic base oil or performance additive to improve viscosity index, low-temperature fluidity, and lubricity.
• Polymer & Plasticizer Intermediate: Used in the synthesis of specialized polymers, resins, and as a precursor for bio-based plasticizers.
• Surfactant & Emulsifier Production: Serves as a key raw material for manufacturing non-ionic surfactants, emulsifiers, and dispersing agents.
• Personal Care & Cosmetics: Functions as an emollient and skin-conditioning agent in creams, lotions, and other cosmetic formulations.
• Metalworking Fluids: Incorporated as a friction modifier and corrosion inhibitor in synthetic and semi-synthetic cutting and grinding fluids.
• Fuel & Biodiesel Additive: Potential use as a cold-flow improver or lubricity enhancer in fuel blends.
