What Is Guar Hydroxypropyltrimonium Chloride?
Guar hydroxypropyltrimonium chloride, one of the most widely used synthetic cationic polymers in the cosmetics industry, is an ingredient that’s often seen in conditioners and body washes. It functions as a conditioning agent for skin and hair, helps deposit active ingredients on skin and/or hair, and also provides anti-static properties without weighing hair down.
