Yes. A number of Indian guar processors make derivatised or modified guar gum, including hydroxypropyl, carboxymethyl, cationic and depolymerised grades. These are used mainly in oilfield, personal care, textile printing, paper and other industrial applications.
Fewer plants make derivatives than plain powder, and capability varies widely. Check the plant, not just the product list.
Common types of modified guar
- Hydroxypropyl guar (HPG): used in fracturing fluids, with lower residue than plain guar.
- Carboxymethyl guar (CMG) and carboxymethyl hydroxypropyl guar (CMHPG): used in oilfield fluids and textile printing.
- Cationic guar, such as guar hydroxypropyltrimonium chloride: a conditioning agent in shampoos and other personal care products.
- Depolymerised or low-viscosity guar: chains shortened for uses that need low viscosity, such as some fibre or industrial products.
- Other modified grades for paper, mining and explosives.
How derivatives are made
Most derivatives are made by reacting guar split or powder with chemicals in a controlled reactor, then washing, drying and grinding. The process needs chemical handling, wastewater treatment and quality control that a simple grinding mill does not have.
That is why it pays to visit the plant. A supplier may offer derivatives but buy them from another manufacturer and resell them. This is not wrong in itself, but you should know who actually makes your product. See how to tell if an Indian agri supplier is a trader or a processor.
What to check before buying
- Reactor capacity and whether the derivative is made in-house.
- Degree of substitution or other measures of modification, with the test method.
- Residual reagents and by-products, especially for personal care grades.
- Viscosity, moisture, pH and mesh against your spec.
- Regulatory status in your market, such as cosmetic ingredient listings or chemical registration where needed.
- Batch consistency over at least a few production runs.
Regulatory points
Modified guar is usually treated as a chemical or cosmetic ingredient, not as a food additive. Depending on the market, it may need registration under chemical rules, such as REACH in the EU, before import. Your importer of record usually carries that duty. Confirm the status of each derivative with your regulatory adviser before you place an order.
For personal care, ask for the INCI name, a safety data sheet and any impurity data your formulators need.
Samples and trials
Derivatives are application-specific. Ask for samples from a production batch, not a lab batch, and test them in your own formulation. Once approved, fix the specification and request a change notice for any process change. Keep retained samples from each lot so later complaints can be checked against what was actually shipped.
How we help
We find plants that make the derivative in-house, audit their reactor and quality set-up, and arrange independent tests on production samples. Begin with a free sourcing review.
