What is N-Oleoylsarcosine CAS 110-25-8?

N-Oleoylsarcosine, also called oleoyl sarcosine or N-oleoyl-N-methylglycine, is a long-chain N-acyl sarcosine with the formula C21H39NO3. It is an amphiphilic oleochemical surfactant used mainly in metalworking, rust-preventive, and specialty lubricant formulations.

Why is N-Oleoylsarcosine used in metalworking fluids?

It acts as a boundary lubricant and corrosion inhibitor, helping to reduce friction and protect metal surfaces during cutting, grinding, and forming operations. Its affinity for metal surfaces also makes it useful in rust-preventive and anti-wear additive systems.

Is N-Oleoylsarcosine water-soluble?

It has limited water solubility and is normally used in oil-based, mineral-oil, or emulsified systems. Neutralization with a suitable base can improve its water compatibility or dispersibility when the formulation requires an aqueous system.

What form is N-Oleoylsarcosine supplied in?

It is typically an amber to brown viscous liquid or semi-solid, depending on temperature. Because its melting point is near room temperature, warming may be needed for easier transfer and blending in cooler conditions.

How does N-Oleoylsarcosine inhibit corrosion?

The carboxylic acid/amide head group adsorbs onto metal surfaces while the long oleoyl chain forms a hydrophobic barrier, reducing contact with water and corrosive species. This film-forming behavior supports its use as an oil-soluble rust inhibitor.

What is the difference between N-Oleoylsarcosine and a salt-form sarcosinate?

N-Oleoylsarcosine is the acid form and is more oil-soluble and weakly acidic, making it suitable for oil-based rust preventives and metalworking fluids. Salt forms such as sodium oleoyl sarcosinate are generally more water-soluble and are used where aqueous detergency or foaming is required.

N-Oleoylsarcosine (NOS) CAS 110-25-8

N-Oleoylsarcosine (CAS 110-25-8) is a fatty acid–derived sarcosine amide commonly used in industrial formulations requiring surface activity, lubrication, and metal affinity. It is particularly valued in metalworking and surface treatment systems where it contributes to boundary lubrication, corrosion inhibition, and dispersion stability. For aqueous cleansing systems, Sodium Lauroyl Sarcosinate is a separate sarcosinate surfactant option.

In commercial supply, N-Oleoylsarcosine is typically provided as a viscous liquid or semi-solid material depending on temperature and composition. It can be incorporated into oil-based or emulsified systems. Standard packaging is available for bulk handling, with supporting documentation such as COA, TDS, and SDS provided for industrial procurement.

Packaging

N-Oleoylsarcosine is supplied as a viscous liquid or semi-solid and is typically packed in sealed drums or intermediate bulk containers (IBC) suitable for handling oleochemical-based materials. Containers are selected to ensure compatibility and to prevent leakage or contamination during storage and transport.

For export supply, packaging is prepared to maintain product stability under varying temperature conditions. Packaging configurations may be adjusted according to order volume and logistics requirements.

Storage

Store in a cool, dry, and well-ventilated area away from direct sunlight and heat sources. Keep containers tightly sealed to prevent oxidation and contamination. Due to its viscosity, warming may be required for easier handling under low-temperature conditions.
