cetrimonium chloride formula

DropPrev® B1631C is a cationic cosmetic ingredient based on Cetrimonium Bromide, supplied as white crystal powder. Cetrimonium bromide is a long-chain alkyltrimethylammonium quaternary ammonium cationic surfactant that primarily serves as a preservative, antimicrobial adjunct, antistatic conditioning agent, and emulsifying aid in cosmetic formulations. Its cationic quaternary ammonium head group adsorbs strongly onto negatively charged surfaces, including microbial cell membranes, hair surfaces, and skin surfaces, which is the common structural basis for its antimicrobial, antistatic, and conditioning performance. The product is suitable for conditioners, shampoos, hair treatments, skin cleansers, and emulsion systems requiring microbial control and cationic conditioning.
