Description

Laurylamine dipropylenediamine (CAS 2372-82-9 ), also known commercially as N,N-bis(3-aminopropyl)dodecylamine, is a long-chain fatty diamine used across industrial and personal care markets. Its combination of a C12 hydrophobic tail and multiple amine groups positions it as a functional ingredient for emulsification, biocidal activity, and corrosion control in various applications. In water treatment, it acts as a biocide and corrosion inhibitor, protecting metal surfaces in cooling towers and industrial water systems. Personal care formulators incorporate it into conditioning systems. It improves wet combability and substantivity in rinse-off hair products. Textile and leather processors use it as a softening and finishing agent, helping fibers retain flexibility and resist microbial degradation. In industrial cleaning formulations, its dual amine functionality supports degreasing performance on metal and hard surfaces where both surfactancy and antimicrobial action are required for effective results. Laurylamine dipropylenediamine is typically supplied as an amber to yellow liquid. Technical grade is the standard commercial offering, with purity specifications commonly in the 95–99% range. Drum and IBC packaging are standard for industrial volumes. This chemical intermediate is valued for its stability and versatility across diverse manufacturing sectors and specialized chemical processes.
