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, also called oleoyl sarcosine, N-oleoyl-N-methylglycine or NOS, CAS 110-25-8, is a fatty acid-derived sarcosine amide supplied as a viscous liquid or semi-solid and positioned for surface activity, lubrication and metal affinity.
