Organic Surfactant Quaternary Ammonium Compounds Ddac-2 CAS 68424-95-3 68424-85-1

Di(octyl/decyl)dimethylammonium Chloride (DODMAC) is a high-performance dialkyl cationic surfactant belonging to the quaternary ammonium compound family. It is synthesized as a defined mixture of octyl (C8) and decyl (C10) alkyl chains, which optimizes its balance of surface activity, solubility, and efficacy. DODMAC is renowned for its multifunctional properties, serving as a powerful microbiocide, an excellent fabric softener base, and a versatile industrial additive.

1. Primary Fabric Softener Active Ingredient
As a core cationic surfactant raw material, it forms a softening film on fiber surfaces through charge adsorption, effectively reducing inter-fiber friction coefficient. It delivers lasting softness, anti-static properties, and fluffiness in various household and industrial textile softeners, particularly suitable for formulating concentrated liquid softeners and dryer sheet products.
2. Key Disinfectant & Biocide Agent
With its unique dialkyl chain structure, it efficiently penetrates microbial cell membranes causing intracellular leakage, demonstrating broad-spectrum bactericidal activity against Gram-positive/negative bacteria, fungi, and algae. Widely used in medical device disinfectants, food processing line cleaners, swimming pool water treatment systems, and microbial control solutions for oilfield water injection systems.
3. Industrial Antistatic Solution
By forming oriented molecular layers on polymer material surfaces, it significantly enhances surface conductivity, effectively addressing winding adhesion issues in plastic film production, electrostatic adsorption in electronic component packaging materials, and discharge spark hazards in chemical fiber processing. It serves as a crucial additive in processing insulating materials like polypropylene and polyethylene.
