Cetyl Trimethyl Ammonium Bromide (CTMAB) also known as Cetrimonium bromide is a highly active quaternary ammonium surfactant that is commonly used as an antiseptic agent against bacteria and fungi. It physically appears as a white colored powder that shows high stability at room temperature but it is highly incompatible with strong oxidizing agents. It can also be used in various applications such as biological, medical, and many more.
