Description
Tetradecyltrimethylammonium bromide (CAS 1119-97-7) is a quaternary ammonium cationic surfactant, commercially known under trade names including Mytab, Morpan T, and Tetradonium Bromide. It carries no assigned E-code and is identified under EC number 214-291-9. Its cationic charge distinguishes it from anionic and nonionic surfactants in formulation design.
In personal care, it adsorbs onto negatively charged hair surfaces to reduce static and improve combability, functioning as a conditioning agent rather than a simple detergent. In water treatment and pharmaceutical manufacturing, its quaternary ammonium structure disrupts microbial cell membranes, delivering measurable antimicrobial activity against bacteria and fungi. It also serves as an emulsifier and lubricity additive in metalworking fluids.
This material is supplied as a fine crystalline powder meeting industrial and cosmetic-grade specifications, with REACH compliance applicable for EU procurement. Buyers should confirm grade suitability against Ph.Eur. or in-house purity thresholds. Standard packaging formats include fibre drums and multi-wall bags; documentation including SDS and COA is available on request.
