Cetrimonium Chloride
Cetrimonium chloride is a conditioning agent and mild antimicrobial commonly used in UK hair care products like conditioners, masks and styling creams. It helps detangle hair, reduce static and leave strands feeling smooth and manageable. It is a gentle quaternary ammonium compound that also helps preserve formulas.
How it works in skincare
In cosmetics and skincare, cetrimonium chloride works as a cationic surfactant that binds to the negatively charged surface of hair fibres, forming a thin protective layer that smooths the cuticle, improves wet and dry combing and reduces friction. It is frequently found in rinse-off conditioners, leave-in sprays and occasional facial cleansers where it provides light conditioning and helps stabilise emulsions.
