Laurylamine dipropylenediamine

Laurylamine dipropylenediamine (CAS 2372-82-9) is a triamine compound traded under names including Triameen Y 12, Lonzabac 12, RC 5637, and DPTA-Y12D. It carries no assigned E-code. The compound belongs to the fatty amine class and is registered under REACH within the European regulatory framework.

In water treatment, it functions as a biocide by disrupting microbial cell membranes, making it effective against bacteria and algae in industrial cooling systems. In textile and leather processing, its amine groups adsorb onto fibre and hide surfaces, providing corrosion inhibition on metal equipment and emulsification of processing oils. It also serves as a degreasing agent in industrial cleaning formulations.

This compound is supplied as a liquid and is available in standard industrial grades compliant with REACH registration requirements. Procurement teams should confirm exact grade specifications, concentration variants such as DPTA-Y12D-30, and packaging formats directly with the supplier.
