Diallyldimethylammonium Chloride

Diallyldimethylammonium chloride (DADMAC)

Diallyldimethylammonium chloride (DADMAC) is a quaternary ammonium salt with the chemical formula C8H16ClN. It is a colorless to pale yellow liquid and is highly soluble in water. DADMAC is widely used as a cationic monomer in the production of water-soluble polymers, which are essential for water treatment, paper manufacturing, textiles, and personal care products. Its strong cationic charge makes it highly effective in coagulation and flocculation processes.

Applications:

  1. Water Treatment: Used as a flocculant and coagulant in wastewater and drinking water treatment.
  2. Paper Industry: Enhances paper strength and improves retention and drainage in the papermaking process.
  3. Textiles & Dyes: Acts as a fixing agent in the dyeing process to improve dye retention.
  4. Personal Care Products: Used in hair conditioners and skin care formulations for its antistatic and conditioning properties.
  5. Oil & Gas Industry: Functions as a clay stabilizer and fluid-loss control agent in drilling operations.
  6. Adhesives & Coatings: Helps improve adhesion and dispersion in various coatings and adhesives.
