Guar hydroxypropyltrimonium chloride

Guar hydroxypropyltrimonium chloride, a water-soluble quaternary ammonium compound (QAV - where all 4 valences of a nitrogen atom are bound) from the guar bean, is widely used in cosmetics (Gao T 2007, see also hair shampoo). Guar hydroxypropyltrimonium chloride is a salt (ionic compound) consisting of a cation and an anion. The substance organizes itself in polymers, reduces static charges by neutralizing electric charges on the surface (e.g. of the hair). Furthermore, the substance forms a coherent film on skin, hair or nails when applied.
