Hydroxypropyl guar gum CAS 39421-75-5

What Hydroxypropyl Guar Gum Is

Hydroxypropyl guar gum is guar gum modified with hydroxypropyl groups, a nonionic galactomannan powder. The ether groups let it hydrate in cold water without lumping, give a clearer salt tolerant solution than native guar and cut residue. In oilfield service it is crosslinked with borate or zirconium to carry proppant, then broken for clean flowback. UATChem supplies oilfield and cosmetic grades, with viscosity, mesh and moisture on the COA.

Fracturing, Personal Care and Industrial Uses

• Hydraulic fracturing. The standard low-damage thickener for water based fracturing fluids in high temperature and low permeability wells. It builds viscosity to carry proppant, tolerates high salinity water and leaves little residue after the gel breaks, helping the fracture flow back cleanly.
• Personal care. Listed under the INCI name Hydroxypropyl Guar, it thickens and suspends in shampoo, conditioner, body wash, toothpaste and creams, adds slip and conditioning and eases surfactant irritation. It pairs well with xanthan gum in clear and salt containing systems.
• Textile, paper and pharmaceutical work. It thickens textile print paste and sizing, aids paper coating and binds or suspends in tablet and liquid preparations; food and pharmacopoeia documentation can be discussed on request.

Typical Specifications

Oilfield and cosmetic grades differ in viscosity, particle size and moisture, reported on the COA for each lot; the table below identifies the material.

Packaging, Documents and Ordering

• Packed in 25 kg kraft bags with polyethylene liners on pallets and in 1000 kg ton bags, matching the warehouse photos, with 1 kg aluminum foil pouches for samples. Keep bags sealed in a cool, dry place because the powder picks up moisture and can cake.
• COA, TDS and SDS are provided for every lot, with viscosity grade, mesh and moisture on the COA. Oilfield and cosmetic grades are available, and food or pharmacopoeia documentation can be discussed on request.
• Samples can be arranged for evaluation. For a quote, UATChem needs the grade, target viscosity or mesh, quantity, packing and destination port.

FAQ

Q: What is hydroxypropyl guar gum used for?

A: It thickens fracturing fluids to carry proppant and adds viscosity and conditioning to shampoo, toothpaste and print paste.

Q: How is HPG different from regular guar gum?

A: It hydrates faster in cold water into a clearer, salt tolerant solution with less residue for low-damage fracturing fluids.

Q: How do I dissolve hydroxypropyl guar gum?

A: Sprinkle it into agitated water to avoid lumps; it hydrates fast in cold water and reaches full viscosity after short mixing.

Q: What viscosity grades and packaging are available?

A: UATChem offers oilfield and cosmetic grades by viscosity and mesh in 25 kg kraft bags, 1000 kg ton bags and 1 kg pouches.
