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 is the secret to the non-stickiness and easy opening of plastic bags and cling film—as the most commonly used slip agent and opening agent in polyethylene and polypropylene films, it migrates from the inside of the film to the surface, forming an invisible lubricating film. It is also an anti-sticking and slip-resistant additive in printing inks, coatings, rubber, and wax products; oleamide is a versatile agent that "makes surfaces slippery."
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).
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.
Chemically, oleamide is a long-chain fatty acid primary amide with stable properties. Its amphiphilic structure, consisting of a polar amide group and a long hydrophobic carbon chain, allows it to oriented and form a lubricating layer on material surfaces. It can react with ethylene oxide to form ethoxylates (nonionic surfactants), and can be hydrolyzed to oleic acid and ammonia. It can participate in addition and condensation reactions. Storage requires protection from moisture and heat, and away from strong oxidizers.
From the perspective of mechanism of action, industrial-grade oleamide plays an irreplaceable role due to its "amphiphilic molecular migration film formation + long-chain lubrication". The 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. It is the most classic slip agent and opening agent for polyolefin films.
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.
Oleamide migrates to the ink and coating surfaces to form a lubricating layer, reducing surface friction and preventing the printed matter and coating from sticking or scratching during winding and stacking.
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.
In summary, industrial-grade oleamide is an "amide that makes surfaces slippery." With its amphiphilic structure 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, from metal processing lubrication to scientific research. It is found in plastics, printing, coatings, rubber, daily chemicals, textiles, machinery processing and scientific research.
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).

Why it works for this purpose: Oleamide is compatible with wax, which can improve the smoothness, gloss and abrasion resistance of the wax film, and improve the customer experience of polishing and care products.
Application fields: Processing of chemical textiles and fibres.
Matched products: spinning oils, fibre lubricants, yarn softeners, non-woven fabric treatment agents, knitting oils, chemical fibre finishing agents, etc.
How it works for this purpose: Oleamide’s lubricating properties help to reduce friction between fibres and yarns during high speed spinning and weaving, reducing breakage and fuzz and improving hand feel and weaveability.
Application areas: Metal forming and cutting operations.

Why it works for this: The long-chain alkyl groups of oleamide form a low-shear-strength lubricating film at the metal friction interface, providing extreme pressure lubrication and friction reduction, thus reducing die wear and workpiece scratches.
To summarise, industrial-grade oleamide (CAS 301-02-0) is an amide that “lubricates surfaces.” It has a wide range of applications, including plastic film slip agents and opening agents, plastic release agents and processing anti-sticking agents, ink anti-blocking and slip additives, coating slip and scratch-resistant additives, rubber processing aids, waxes and polishing agents, textile and fibre oils and metalworking lubricants due to its amphiphilic molecular migration film-forming and long-chain lubrication properties. Slip additives for plastic films are the largest core area of consumption. Note: Oleamide used in food-contact plastics must meet migration limits. Dust may irritate the respiratory tract and ventilation and dust prevention are needed during processing.
