Application

Dodecyltrimethylammonium bromide, appearing as a white to slightly yellow powder, is a versatile quaternary ammonium salt primarily used for its surfactant properties. It serves multiple purposes including acting as an emulsifier in rubber and asphalt, an anti-static agent for synthetic fibers, and a stabilizer for foams. Its functions extend to being a critical component in paint strippers and bactericidal lotions. Additionally, this substance plays a role in research, aiding in the preparation of gold nanoparticles and supporting studies on micelle formation through conductimetry and other techniques. It is also actively involved in biochemical applications, particularly in proteomics research and the investigation of surfactant interactions, such as assessing binary mixed counterions in adsorbed films and exploring surfactant chain compatibility for extracting organophosphorous pesticides.
