What This Grade Is For
White Powder Hydroxyethyl Cellulose is supplied by Yiyuantong Chemical as a multi-purpose thickener, binder and stabiliser for water-based systems. The listing is the standard white powder presentation, the format most incoming inspections are written around. Hydroxyethyl cellulose (HEC), chemical formula (C2H6O2)n, is a white or light yellow, odorless, non-toxic fibrous or powdered solid, prepared by etherification reaction of alkaline cellulose and ethylene oxide (or chloroethanol), and belongs to non-ionic soluble cellulose ethers.
Key Benefits
- Thickens, suspends, disperses, emulsifies and forms films from a single additive
- Consistent white powder appearance, screened at 40 mesh, so dosing and dispersion behave the same lot to lot
- Stays effective in salty and hard water because the polymer is non-ionic
- Dissolves in cold water to a clear, viscous solution without a cooking step
- Supplied across a wide viscosity range so the grade can be matched to the process
- Held in stock: 800 tonnes of HEC are carried year round, and confirmed orders ship to the named port within 3 working days
Problems It Solves
- Water-based formulations that need viscosity without losing clarity
- Solids that settle out of suspension during storage
- Systems that lose viscosity when salt or hardness is introduced
Application Scenarios
- Water-based industrial formulations
- Suspension and emulsion stabilisation
- Film-forming and binding applications
- Protective colloid systems
Who It Is For
- Chemical formulators
- Industrial blenders
- Speciality product manufacturers
Technical Features
- Non-ionic backbone, so viscosity survives salt and hard water
- Cold-water soluble, no cooking step needed in the mixing room
- Supplied from 300 to 200000 mPa.s so the grade can be matched to the process
- Molar degree of substitution of 1.8 to 3.0 for biological stability and high transmittance
- Solvent process raises the degree of substitution by 30 to 35 percent against traditional routes

Raw Materials
- High alpha-cellulose refined cotton
- Wood pulp with high cellulose content
- Ethylene oxide
Manufacturing Process
- Alkalisation of refined cotton and wood pulp
- Etherification with ethylene oxide
- Acetone countercurrent washing
- Drying and milling
- 40 mesh screening
- Lot testing and packing
Quality Control
- Every lot is tested in our own laboratory against the customer specification before release

- Acetone countercurrent washing removes process residues before drying and milling
How It Compares
| Anionic thickeners | The non-ionic backbone keeps viscosity stable where salts would knock down an anionic polymer |
|---|---|
| Synthetic associative thickeners | Cellulose ether is less dependent on the surfactant balance of the formulation |

White Powder Hydroxyethyl Cellulose FAQ
How do I choose between viscosity grades?
Start from the viscosity your process needs and the shear it applies. Send both and we will recommend a grade from the 300 to 200000 mPa.s range.
Can I get a sample before ordering?
Yes. Samples ship by FEDEX, DHL or EMS; some are free and you cover the freight.
How consistent is the appearance between lots?
Appearance, screening rate and water content are checked on every lot. Any deviation is reported on the certificate of analysis before the goods leave.
Are you a manufacturer or a trading company?
We are a manufacturer and you are welcome to visit the plant. Our hydroxyethyl cellulose project runs at 5000 tonnes a year on an acetone countercurrent washing process.
What payment terms do you accept?
L/C, T/T, D/A, D/P, PayPal and Western Union. We have worked with China Export and Credit Insurance Corporation for many years.
How fast can you ship?
Stock items are despatched within 5 days of payment. If the grade is not in stock, production and despatch take 7 to 10 days from payment.
