Dioctyldimethylammonium chloride

Dioctyldimethylammonium chloride (CAS 5538-94-3) is a quaternary ammonium compound marketed under trade names including Bardac LF, Dodigen 2617, RC 5626, and HOE-S 2617. It carries no E-code designation and is classified under HS code 29239000. It belongs to the dialkyl quat subclass of cationic surfactants.

In water treatment, it disrupts microbial cell membranes at low concentrations, making it effective for algae and bacteria control in cooling towers and industrial water systems. In textile and leather processing, its cationic charge enables substantive adsorption onto negatively charged fibre surfaces, providing durable antimicrobial and softening effects.

This compound is supplied as a liquid grade and is registered under REACH. Procurement teams should confirm supplier SDS documentation for concentration and solvent composition, as commercial grades vary. Standard industrial packaging applies; buyers should request specification sheets to verify active content and compliance with regional biocidal product regulations.
