guar hydroxypropyltrimonium chloride (GHPT) is an anti-irritant and anti-inflammatory that is also used as a thickening, conditioning, and anti-static agent. It helps maintain a product’s smoothing action. Some manufacturers cite it as also having skin-softening capabilities. It imparts excellent skin conditioning in creams or lotions that otherwise may not be used on the face. It adds lubricity to a product when in contact with the skin. There is some evidence that it can enhance a formulation’s viscosity and stability. It is a derivative of guar gum.
