N-Oleoylsarcosine is an N-acyl amino-acid surfactant — the oleoyl amide of sarcosine (N-methylglycine) — supplied as a pale-yellow, oil-soluble liquid or semi-solid. It is one of the most effective ashless rust inhibitors and corrosion inhibitors used in lubricants, rust-preventive oils and metalworking fluids, protecting ferrous metals by chemisorbing onto the metal surface.
Its value lies in multifunctionality: the carboxyl group anchors to metal surfaces forming a protective film, the oleoyl chain confers oil solubility and lubricity, and the amide structure adds extreme-pressure and emulsifying character. One molecule delivers rust prevention, corrosion inhibition, flotation and mild lubrication — which is why it is the standard choice in rust-preventive oils, high-sulfur lubricants and pipeline corrosion protection.
A single surfactant, four core value propositions:
Rust Prevention & Corrosion Inhibition:
● a benchmark ashless rust/corrosion inhibitor for lubricants, greases and rust-preventive oils;
Metalworking Fluids:
● an effective anti-rust additive for cutting fluids and emulsions, often boosted by sulfonate combinations;
Fuel & Pipeline Additives:
● corrosion protection for fuels, storage tanks and pipelines;
Surfactants, Flotation & Specialty:
● a collector in mineral flotation, a mild cosmetic surfactant and a multifunctional process additive.

N-Oleoylsarcosine is an N-acyl derivative of sarcosine: a C18:1 oleoyl chain attached through an amide bond to the nitrogen of N-methylglycine. The molecule is amphiphilic and anionic — a carboxylic acid head that chemisorbs onto metal surfaces plus a long oil-soluble oleoyl tail. The resulting adsorption film displaces water and blocks corrosive attack, which is the mechanism behind its outstanding rust inhibition at very low dosage.
As an ashless additive, N-oleoylsarcosine leaves no metallic residue in oils, preserves lubricant performance, and works synergistically with sulfonates and other inhibitors.
● Outstanding rust inhibition: Chemisorbs on ferrous surfaces to provide protection against rust at low dosage.
● ●Ashless chemistry: No metallic residue, keeping oil clean and performing.
● ●Excellent oil solubility dissolves cleanly in mineral and synthetic oils, greases and fuels.
● ●Multi-functional action: rust prevention, corrosion inhibition, flotation and mild EP lubrication in one molecule.
● ● synergy with sulfonates: combinations considerably improve cast-iron rust protection in oils and fluids
● Proven in high-sulfur systems: effective corrosion inhibitor in high-sulfur lubricant environments.
● Broad formulation reach: lubricants, greases, rust-preventive oils, metalworking fluids, fuels and flotation.
● Grade flexibility: industrial, metalworking and cosmetic grades with custom packaging.
N-Oleoylsarcosine is a benchmark inhibitor of the lubricant industry:
● Rust-preventive oils: anti-rust component for temporary metal protection
● Engine and gear oils: rust and corrosion protection, including high-sulfur systems;
● Marine and long-term storage: protective film for stored and transported metal goods.
● Cutting and grinding fluids: anti-rust additive in soluble oils and emulsions;
● Tapping and forming oils: lubricity and corrosion protection in severe operations;
● Sulfonate combinations: paired with sulfonates for enhanced cast-iron rust prevention;
● Temporary protection: film-forming protection of machined parts between operations.
● Fuel corrosion inhibition: protects storage tanks, pipelines and fuel systems from corrosion;
● Pipeline transport: corrosion control for fuel and crude-oil pipelines;
● Fuel additives: multifunctional additive in gasoline, diesel and industrial fuels.
● Mineral flotation: collector in ore benefication (flotation of oxide and carbonate ores);
● ●Cosmetics: mild surfactant sarcosinate in mild cleansing formulations;
● Cleaning products: Speciality cleaners containing surfactants that inhibit corrosion;
● ●Emulsifier/process aid: emulsifying and corrosion inhibiting in industrial formulations.

Q1: What is N-oleoylsarcosine used for?
N-Oleoylsarcosine is used as an ashless rust and corrosion inhibitor in lubricating oils, greases and rust-preventive oils; as an anti-rust additive in metalworking fluids; as a corrosion inhibitor for fuels and pipelines; and as a flotation collector and mild surfactant in mining and cosmetic applications.
Q2: Why is N-oleoylsarcosine such an effective rust inhibitor?
Its carboxylic-acid head chemisorbs onto ferrous metal surfaces, forming a dense protective film that displaces water and blocks oxygen and corrosive species, while the oleoyl tail keeps the molecule oil-soluble. Because it is a strong chemical adsorption rather than a physical barrier, it protects at very low dosages and survives demanding high-sulfur and humid environments.
Q3: Is N-oleoylsarcosine safe to handle?
N-Oleoylsarcosine has low acute toxicity but can irritate the skin and eyes, and the semi-solid should be warmed gently for handling. Use gloves and goggles, avoid skin and eye contact, and keep it away from oxidizers. It is an industrial chemical; cosmetic use must comply with the destination market's regulations.
