Nonadecanoic acid

Nonadecanoic acid (CAS 646-30-0) is a saturated straight-chain fatty acid with the molecular formula C19H38O2, also referenced as C19:0, 19:00, or NSC 11914. It carries no assigned E-code and is not listed as a food additive under current EU or Codex frameworks. The nonadecanoate form refers to its salt and ester derivatives used across industrial applications.

In personal care formulations, nonadecanoic acid functions as an emulsifier by reducing interfacial tension between oil and water phases, improving texture stability in creams and lotions. In lubricant and metalworking fluids, it acts as a boundary lubricant, forming a protective molecular layer on metal surfaces to reduce friction and wear under load.

This material is supplied in fine powder and shiny flake grades to suit different handling and dosing requirements. It is registered under REACH and available with documentation supporting industrial and cosmetic applications. Standard packaging follows European bulk chemical conventions for solid fatty acids.
