Oleamide, also known as oleic acid amide, cis-9-octadecenoamide (chemical formula C18H35NO, CAS 301-02-0), is a fatty amide of oleic acid, a milky white to light yellow waxy solid. It serves as both an industrial slip agent for plastic bags and cling film, making them non-sticky and easy to open, and as an anti-sticking and slip-resistant additive in printing inks, coatings, rubber, and wax products. Oleamide is a versatile agent that "makes surfaces slippery and puts the brain at ease."
Basic identification information: Molecular formula C18H35NO, molecular weight 281.48, CAS number 301-02-0, EC number 206-103-9, PubChem CID 5283387, UNII 7L25QK8BWO; prepared by amidation of oleic acid (cis-9-octadecenoic acid) with ammonia (or urea), and purified to obtain different grades;
Physically, it is a milky white to light yellow waxy solid (in flakes, powder, or granules); density is about 0.879 g/cm³; melting point is about 70℃ (68-76℃ for industrial products); boiling point is above 200℃; insoluble in water, soluble in organic solvents such as ethanol, ether, and chloroform; flash point is above 200℃, with good thermal stability, and does not decompose at plastic processing temperatures.
In terms of chemical and biological properties, oleamide is a long-chain fatty acid primary amide with stable chemical properties. It possesses an amphiphilic structure with a polar amide group and a long hydrophobic carbon chain, allowing it to oriented and form a lubricating layer on material surfaces. It can react with ethylene oxide to form ethoxylates and can be hydrolyzed to oleic acid and ammonia. Storage requires sealing, moisture protection, protection from heat, and keeping away from strong oxidizers.
From the perspective of its mechanism of action, oleamide plays an irreplaceable role through "amphiphilic molecular migration for film formation + long-chain lubrication," and its mechanism of action in different applications is as follows:
Oleamide has limited compatibility with polyethylene and polypropylene. After processing, it slowly migrates to the film surface to form a monomolecular lubricating layer, which significantly reduces the coefficient of friction, making the film easy to open, non-sticky, and easy to cut.
Oleamide forms a lubricating film at the interface between plastics, rubber and molds, reducing the adhesion between the product and the mold, improving demolding properties and preventing the products from sticking together.
The alkyl chains of long-chain fatty acid amides form a low-shear-strength lubricating film at the friction interface, providing extreme pressure lubrication and friction reduction, and are used in metal processing and fiber oils.
Oleamide is rapidly hydrolyzed by FAAH and is a natural substrate of FAAH; high-purity products have a defined composition and traceable content, and can be used as chromatographic and mass spectrometric standard substances to ensure accurate quantitative detection.
In summary, oleamide is an "amide that makes surfaces slippery and puts the brain to sleep." Through amphiphilic migration to form films and long-chain lubrication, it is used in a wide range of fields, from plastic films to mold release and anti-sticking, from inks and coatings to rubber wax products, including plastics, printing, coatings, rubber, daily chemicals, textiles, machining and analysis and testing.
Applications: Polyolefin films, plastic packaging.
Similar Products: Slip agents for polyethylene (LDPE/HDPE/LLDPE) blown films, polypropylene (PP) cast films, BOPP bi-axially orientated films, CPP cast films, food packaging films, agricultural films, composite films, plastic bottle and cap liners, slip masterbatches, etc.
Why it works for this purpose: Oleamide is not very compatible with polyolefins. After processing, it gradually migrates to the surface of the film, forming a monomolecular lubricating layer, which greatly reduces the coefficient of friction. This makes the film easy to open, non-stick and easy to cut. It is the most classical slip agent and opening agent for polyolefin films (food contact must comply with migration limits).

In summary, oleamide (CAS 301-02-0) has a broad spectrum of uses for its amphiphilic migration film-forming properties and long-chain lubrication including in the role of a plastic film slip agent and opening agent, plastic release agent and processing anti-sticking agent, ink anti-blocking and slip additive, coating slip and anti-scratch additive, rubber processing aid, wax products and polishing agent, textile and fibre oil, metal processing lubricant, analytical testing standard and research . Of these, the largest core area of consumption is plastic film slip agents, and the highest value-added scientific application is neuroscience studies. Note: Oleamide for use in food contact plastics must meet migration limits. Dust can irritate the respiratory tract, and so ventilation and dust prevention are important in processing and research operations.
