Description
Diallyldimethylammonium chloride (DADMAC, CAS 7398-69-8) is a quaternary ammonium monomer commercially available under trade names including C 1615, Nalco 7544, and C 1615M-BR 30. It carries no assigned E-code and is classified under HS code 29239000 within the broader category of polymers and resins.
In water treatment, DADMAC-based polymers act as cationic coagulants, neutralising negatively charged suspended particles to accelerate flocculation and clarification. In pulp and paper manufacturing, it functions as a retention aid and charge-control agent, improving fibre bonding and reducing effluent load. Its quaternary nitrogen centre also delivers antimicrobial activity relevant to preservation applications in personal care and textile processing.
DADMAC is supplied in liquid form and is subject to REACH registration requirements for EU market access. Procurement teams should confirm polymer molecular weight grade and active content specification, as these vary by application. Standard packaging follows bulk liquid formats typical for industrial quaternary ammonium compounds.
