Guar Gum (Guaran, E412)

Guar
CAS 9000-30-0

Cold-water-soluble galactomannan that delivers high viscosity at low dose across food and oilfield fluids. Used as a thickener, stabilizer, and water-binder in food (E412), as a gellant in oilfield hydraulic-fracturing fluids, and in textile printing, paper, mining, and personal-care formulations.

Full Description

A galactomannan polysaccharide milled from guar (Cyamopsis tetragonoloba) seed endosperm (CAS 9000-30-0). Used as a thickener, stabilizer, and water-binder in food (E412), as a gellant in oilfield hydraulic-fracturing fluids, and in textile printing, paper, mining, and personal-care formulations.

Frequently Asked Questions

What is guar gum used for?

Guar gum (CAS 9000-30-0) is a galactomannan polysaccharide used as a thickener, stabilizer, and water-binder in food (E412), as a gellant in oilfield hydraulic-fracturing and drilling fluids, and in textile printing, paper, mining flotation, and personal-care formulations. RawSource supplies it in bulk across these industrial sectors.

Is guar gum natural or artificial?

Guar gum is a naturally derived polysaccharide milled from the seed endosperm of the guar plant (Cyamopsis tetragonoloba). It is not a synthetic polymer. Request the CoA and origin documentation for sourcing details on a given lot.

What is the difference between guar gum and xanthan gum?

Guar gum is a plant-seed galactomannan that thickens cold water, while xanthan gum is a microbial-fermentation polysaccharide with different shear and synergy behavior; the two are often used together for combined viscosity and stability. RawSource can quote both for formulation trials. Specify your viscosity and grade target on the RFQ.

What grades and viscosities of guar gum are available in bulk?

Guar gum is produced in a range of mesh sizes and viscosity grades for food, oilfield, and industrial use. RawSource quotes to your target viscosity, particle size, and application; specify these on your RFQ and we will confirm an available grade with CoA and SDS.

How is bulk guar gum packaged?

RawSource ships guar gum powder in bulk bags and drums sized for manufacturing and oilfield-service volumes. Provide your quantity, grade, and ship-to on the RFQ for a current bulk quote.
