Cationic Guar (INCI: Guar Hydroxypropyltrimonium Chloride)

Cationic Guar – A Versatile Conditioning & Thickening Agent

Cationic Guar, known by the INCI name Guar Hydroxypropyltrimonium Chloride, is a water-soluble, quaternary ammonium derivative of natural guar gum. It is a cationic polymer widely used in personal care formulations. Its positive charge provides substantivity to anionic surfaces such as hair and skin, making it an effective conditioning agent.

In haircare products like shampoos and conditioners, it improves wet and dry combability, reduces static, and imparts a smooth, soft feel without weighing hair down. For skincare, it functions as a conditioning agent, helping to deposit active ingredients and leaving the skin feeling smooth and soft. Beyond its conditioning properties, Cationic Guar also contributes to thickening and regulating the rheology of aqueous solutions and surfactant-based systems.
