Tetradecyltrimethylammonium Bromide
Tetradecyltrimethylammonium Bromide (CAS: 1119-97-7), commonly abbreviated TTAB, is a cationic surfactant with a C14 alkyl tail and a quaternary ammonium head group. It lowers surface tension and forms well-defined micelles in water, making it a standard choice for emulsification, dispersion, and conditioning in personal care, cleaning, and industrial processing applications. It is also a widely used reagent in micelle and colloid research. The bromide salt dissolves readily in water to give clear solutions and stores well as a dry crystalline powder. Customers select it where a well-characterized cationic surfactant with strong surface activity is required.
• Cationic surfactant: a C14 quaternary ammonium that lowers surface tension and forms defined micelles.
• Personal care: used as a conditioning and emulsifying agent in hair and skin products.
• Industrial: an emulsifier and antistatic agent for cleaning, textiles, and processing applications.
• Research: a standard reagent for micelle, colloid, and phase-transfer chemistry studies.
