Dodecylammonium chloride

Dodecylammonium chloride (CAS 929-73-7 ), also sold as dodecylamine hydrochloride and laurylamine hydrochloride, is a cationic amine salt used across surface treatment, cleaning, and personal care manufacturing.

It functions primarily as a surfactant, emulsifier, and corrosion inhibitor, providing controlled surface activity in both aqueous and mixed-solvent systems for industrial applications.

In textile and leather processing, it acts as a wetting and softening agent, improving dye penetration and surface uniformity on treated substrates during the manufacturing process.

Industrial and institutional cleaning formulations incorporate it for its emulsification performance and ability to break down oily soils on hard surfaces effectively and efficiently.

Personal care manufacturers use it as a conditioning agent in rinse-off products, where its cationic character improves substantivity to hair and skin for better consumer results.

In metalworking and industrial maintenance, it functions as a corrosion inhibitor, forming a protective layer on metal surfaces exposed to aggressive environments and moisture.

Dodecylammonium chloride is supplied as a white to off-white crystalline powder or as an aqueous solution at varying active concentrations depending on the specific client requirements.

Technical grade is the most common commercial form, with purity specifications typically ranging from 95% to 99%. Some suppliers offer material to cosmetic-grade standards for personal care.
