Industrial, Cosmetic & High Purity Grade Distearyldimethylammonium Chloride (D1821) CAS 107-64-2 Dioctadecyl Dimethyl Ammonium Chloride Cationic Surfa

Dioctadecyl Dimethyl Ammonium Chloride (Abbr: DODMAC / D1821, CAS:107-64-2,EINECS:203-508-2, HS Code:2923900000) is a white to light yellow flake or paste, a cationic quaternary ammonium surfactant. We supply industrial and cosmetic grades complying with international quality standards. It features excellent softening, antistatic, emulsifying and bactericidal properties, soluble in ethanol and polar solvents, dispersible in warm water. Widely used as fabric softener, antistatic agent, emulsifier and bactericidal agent across textile, daily chemical and other industries.

Applications
Textile Industry (Core Application)
Premium fabric softener for cotton, wool, silk and synthetic fabrics. It endows textiles with excellent softness, smoothness and antistatic properties, reduces fabric wrinkling, improves fiber elasticity and wear resistance, and gives fabrics long-lasting fluffy and comfortable hand feel.
Daily Chemical Industry
Key raw material for fabric softeners, hair conditioners and skin care products. It softens hair, reduces static electricity, improves combability, and provides smooth and moisturizing effect to skin and hair, widely used in household care and personal care formulations.
Emulsification & Dispersion
Used as cationic emulsifier for silicone oil, wax, asphalt and rubber. It stabilizes emulsion systems, improves dispersion uniformity, and is widely applied in leather finishing, paper coating and industrial emulsion production.
Bactericidal & Antiseptic
Broad-spectrum bactericidal agent for industrial circulating water, wood preservation and leather anti-mildew. It inhibits growth of bacteria and fungi, prevents material spoilage and extends service life of products.
Paper & Leather Industry
Applied as paper softener and leather fatliquoring agent. It improves paper softness and folding resistance, enhances leather softness and fullness, and improves processing performance of paper and leather products.
Other Industrial Applications
Used as antistatic agent for plastic and rubber products, and as flocculant for wastewater treatment. Also applied in coating additives, textile printing and dyeing auxiliaries and mineral processing agents.
