Dodecylamine hydrochloride

Dodecylamine hydrochloride (CAS 929-73-7, EC 213-205-7), also known as laurylammonium chloride or dodecylammonium chloride, is the hydrochloride salt form of dodecylamine. It carries no assigned E-code and is classified under HS code 29211999. It belongs to the primary aliphatic amine category with the molecular formula C12H27N.ClH.

In water treatment and mining, it functions as a corrosion inhibitor by adsorbing onto metal surfaces through its amine group, forming a protective molecular barrier that displaces water and blocks oxidative attack. In textile and personal care formulations, it acts as an emulsifier and surface-active agent, reducing interfacial tension to stabilise dispersions and improve substrate wetting.

Dodecylamine hydrochloride is supplied as a white powder and is subject to REACH registration requirements for EU procurement. Buyers should confirm supplier compliance documentation, including Safety Data Sheets aligned with EU GHS standards. Standard packaging formats vary by supplier; technical and commercial grades are typically available.
