n-Oleoylsarcosine

N-Oleoylsarcosine (CAS 110-25-8) is a fatty acid sarcosine derivative, commercially known under trade names including Sarkosyl O and Medialanic acid. It belongs to the N-acyl amino acid surfactant class, carrying no assigned E-code. The compound is also referred to as oleic sarcosine or oleoylsarcosine in technical literature.

In metalworking fluids, N-oleoylsarcosine adsorbs onto metal surfaces to form a protective monolayer that inhibits corrosion by displacing moisture and blocking oxidative attack. In personal care formulations, it functions as a mild emulsifier and foam modifier, reducing surface tension while remaining compatible with skin-conditioning systems. It also serves as a degreasing agent in industrial cleaning concentrates.

N-Oleoylsarcosine is supplied as a technical-grade material and is subject to REACH registration requirements within the European Economic Area. Standard packaging formats include drums and IBCs. Buyers should confirm grade specifications and documentation, including SDS and certificate of analysis, prior to procurement.
