Description

Dodecan-1,12-Diylbis(Benzyldimethylammonium) Dichloride is a high-purity, synthetic quaternary ammonium compound (QAC) primarily valued for its potent and persistent antimicrobial and surfactant properties. This dialkyl chain gemini surfactant is engineered for superior performance in formulations requiring enhanced biocidal efficacy and surface activity. It is a critical raw material for manufacturers in the disinfectant, biocide, textile, and personal care industries, where reliable and effective cationic agents are essential.

Application

• Disinfectant & Biocide Formulations: As a key active ingredient in industrial, institutional, and agricultural disinfectants due to its broad-spectrum antimicrobial activity against bacteria, fungi, and viruses.
• Textile & Fiber Treatment: Used as a durable antimicrobial finish for fabrics, medical textiles, and technical fibers to impart long-lasting hygiene properties.
• Personal Care & Cosmetics: Employed as a preservative and conditioning agent in rinse-off products like shampoos and body washes, where its cationic nature provides antistatic and softening benefits.
• Industrial Water Treatment: Functions as an algicide and microbiocide in cooling towers, pulp/paper processing, and oilfield water systems to control microbial growth and biofouling.
• Surface Modifier & Antistatic Agent: Applied in coatings, plastics, and polymer processing to improve surface wetting, adhesion, and reduce static charge.
• Research & Development: Serves as a reference standard and building block in chemical synthesis for developing new surfactants and biocidal compounds.
