Whatsapp Order

Cetyl Trimethyl Ammonium Chloride (CTAC) is a cationic surfactant and quaternary ammonium compound characterized by a long hydrophobic cetyl (C16) alkyl chain and a positively charged ammonium head group. It appears as a white to pale yellow powder or flakes, soluble in water, and exhibits strong surface-active properties. CTAC is widely used in cosmetics, personal care, and industrial applications for its excellent conditioning, antistatic, emulsifying, and disinfectant capabilities. It functions primarily as a fabric softener, hair conditioner, and antimicrobial agent.
