Origin

Guar hydroxypropyltrimonium chloride is a plant-based ingredient that is extracted from guar beans. Even though it is sourced from natural means, it is still synthetic because of the way it is made. After the extraction process is complete and a natural gum has been obtained from the guar beans, it is then purified and filtered. After this, the natural gum is reacted with epoxides to make Guar hydroxypropyltrimonium chloride.
