Tetradecanedioic acid

Tetradecanedioic acid (CAS 821-38-5) is a long-chain dicarboxylic acid commercially available under trade names including Emerox 114 and DCA 14, and referenced in research literature as NSC 9504. It carries no assigned E-code and is classified under HS code 29171900 within the organic acids category.

In personal care formulations, it functions as an emulsifier and hair conditioner by anchoring to both aqueous and lipid phases through its dual carboxyl groups, improving emulsion stability and deposit on hair fibers. In metalworking and lubricant applications, its bifunctional acid structure forms boundary-layer films on metal surfaces, reducing friction and wear under load.

The material is supplied as a white fine powder suitable for direct compounding. It falls under REACH registration requirements for EU supply and should be evaluated against FCC or Ph.Eur. standards depending on end-use application. Procurement teams should confirm grade specification and packaging format with the supplier prior to ordering.
