Dodecyltrimethylammonium Bromide
Dodecyltrimethylammonium Bromide (CAS: 1119-94-4), commonly called DTAB, is a white crystalline cationic surfactant with a C12 alkyl tail and a quaternary ammonium head group. It lowers surface tension and forms well-defined micelles in water, making it a standard surfactant for emulsification, dispersion, and antimicrobial formulations. It is used as an emulsifier for rubber and asphalt, an antistatic agent for synthetic fibers, and a research reagent for micelle and colloid chemistry. The bromide salt dissolves readily in water to give clear solutions and stores well as a dry powder. Customers select it where a well-characterized cationic surfactant with strong surface activity is required.
• Cationic surfactant: lowers surface tension and forms defined micelles for emulsification and dispersion.
