Dodecyldimethylethylammonium Bromide (EDDAB)
CAS 68207-00-1
Dodecyldimethylethylammonium Bromide (CAS 68207-00-1) is a high-performance cationic surfactant belonging to the quaternary ammonium compound family. It is widely recognized for its dual functionality as a potent broad-spectrum biocide and an effective fabric/hair conditioning agent. Available typically as a clear, pale yellow aqueous solution (50% or 70% active matter) or as a high-purity solid, EDDAB offers excellent water solubility and compatibility with various formulations. Its mechanism involves the disruption of microbial cell membranes for disinfection and electrostatic adsorption onto negatively charged surfaces for softening and conditioning. This versatility makes it a critical ingredient in disinfectants, fabric softeners, hair care products, and numerous industrial applications such as emulsification, phase-transfer catalysis, and corrosion inhibition. Manufactured under strict quality control, our EDDAB ensures consistent purity, low free amine content, and reliable performance for global industrial and consumer product formulators.
>> Main Uses
Dodecyldimethylethylammonium Bromide (EDDAB, CAS 68207-00-1) serves as a versatile cationic surfactant with three core industrial applications. Primarily, it functions as a highly effective broad-spectrum biocide and disinfectant in household, institutional, and industrial cleaning formulations, as well as in water treatment systems for algae and bacterial control. Secondly, its strong affinity for negatively charged surfaces makes it an essential conditioning agent, extensively used as the active component in commercial fabric softeners to impart antistatic properties and softness, and in hair care products for detangling and shine enhancement. Furthermore, in industrial processes, EDDAB acts as a reliable emulsifier for asphalt and pesticides, a phase-transfer catalyst in organic synthesis, and a corrosion inhibitor in oilfield and metal treatment applications. This multi-functionality stems from its unique molecular structure, allowing it to perform critical roles in sanitation, material softening, and chemical process optimization across diverse sectors.
