Overview

Cyamopsis tetragonoloba gum is a plant-based gum extracted from the seeds of guar, or cluster bean, with the botanical name Cyamopsis tetragonoloba.

In skincare, it is used as a thickener and gelling agent. The plant’s origins are a mystery since it has never been found in a wild. It has, however, been cultivated in India and South Asia for centuries.

Guar gum is comprised of various polysaccharides with very large molecules and long chains. It is soluble in water, creating a viscous colloidal solution. Calcium or borax, when added to guar gum solution, will cause it to form a thick gel.
