Guar gum is widely used in the food industry as a thickening and stabilizing agent. It is commonly added to products like ice cream, yogurt, and sauces to improve texture and prevent separation. In baked goods, it enhances dough elasticity and moisture retention.

In the pharmaceutical sector, guar gum is utilized as a binder and disintegrant in tablets, ensuring they hold together while also breaking down efficiently when ingested. It is also used in controlled-release drug formulations due to its gel-forming properties.

The cosmetic industry employs guar gum as a thickener and emulsifier in products like lotions, creams, and shampoos, providing a smooth and consistent texture.

In oil and gas drilling, guar gum is a key component in hydraulic fracturing fluids, where it increases viscosity to carry proppants into fractures.

Additionally, it is used in the textile and paper industries as a sizing agent and in mining as a flocculant to separate solids from liquids. Its versatility across industries makes it a valuable additive.
