Oleic Acid, identified by CAS 112-80-1, is a long-chain monounsaturated omega-9 fatty acid and carboxylic acid characterized by a single cis-double bond at the C-9 position. This organic lipid functions as a versatile chemical intermediate and lubricating agent, facilitating the synthesis of metallic oleates, specialized esters, and surface-active derivatives within large-scale industrial manufacturing. As a fundamental fatty acid chain, 9-octadecenoic acid serves as a critical raw material in the production of industrial soaps, textile softeners, and metalworking fluids where high oxidative stability and solvency are required. Its unique molecular structure allows it to act as an effective emulsifier and dispersion stabilizer in oil-in-water systems for construction and coating applications. We provide this material with competitive factory pricing to support continuous chemical production, offering customized specifications to meet specific titer and iodine value requirements. Comprehensive technical support is integrated into our service, providing MSDS, TDS, COA with every shipment to ensure regulatory compliance in bulk supply operations.

1. It is mainly used to prepare plastic plasticizers butyl epoxy oleate and octyl epoxy oleate. Used in the wool textile industry for the preparation of antistatic agents and lubricating softeners. It is used in the wood industry to prepare water-resistant paraffin emulsions. Azelaic acid can be prepared by oxidation, which is the raw material for making polyamide resin. It can also be used to manufacture emulsifiers, printing and dyeing auxiliaries, industrial solvents, mineral flotation agents and release agents. It can also be used to prepare carbon paper, typewriter, ballpoint pen oil and various oleates.
2. It can be used as a lubrication and seizing agent for drilling mud. The sodium or potassium salt of oleic acid is a component of soap. Pure sodium oleate has good decontamination ability, can be used as a surfactant such as emulsifier, and can be used for cholelithiasis. Other metal salts of oleic acid can also be used in waterproof fabrics, lubricants, polishes, etc.
3. Used for biochemical analysis and gas chromatography reference materials.
4. It is used to prepare plastic plasticizers, emulsifiers, lubricants, ointments, ore flotation agents, etc.
5. It is used as a raw material for detergents, fatty acid soap bases, cosmetics, chemical fiber oils, and textile auxiliaries. Refined oleic acid is used as a raw material for plastics, engineering plastics, nylon 8 and nylon 9.

FAQ - Technical & Supply Chain
-
Q:
How is the chemical identity of CAS 112-80-1 verified against saturated fatty acids like Stearic Acid?
A: Identity is confirmed through iodine value testing and gas chromatography, which detect the presence of the characteristic carbon-carbon double bond, distinguishing its liquid state and higher reactivity from the saturated, solid profile of stearic acid. -
Q:
What is the common functional role of this chemical in industrial lubricant manufacturing?
A: It is typically applied as a friction modifier and corrosion inhibitor in metalworking and drilling fluid formulations, where its polar head group anchors to metal surfaces to provide a stable, protective lubricating film.
