Product Description:
Hexadecyl trimethyl ammonium bromide (CTAB) is widely used as a cationic surfactant in various applications. It is commonly employed in DNA extraction processes, where it helps to break down cell membranes and precipitate nucleic acids, making it essential in molecular biology and genetic research. In nanotechnology, CTAB serves as a stabilizing agent in the synthesis of gold and silver nanoparticles, controlling their size and shape. It is also utilized in the formulation of hair conditioners and fabric softeners due to its ability to reduce static and improve texture. Additionally, CTAB finds use in the petroleum industry as a corrosion inhibitor and in the preparation of colloidal systems for industrial applications. Its antimicrobial properties make it effective in disinfectants and sanitizers.
