Hydroxyethyl Cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose and ethylene oxide, widely used as a thickening, binding, and stabilizing agent.

As a chemical auxiliary agent, the Hydroxyethyl cellulose HEC can provide the following properties to the construction and oil drilling product:
Film Formation
Enzyme Resistance
Water Retention
Surface Activity
Pseudoplasticity
PH Stability
Thickening & Binding
The production process of HEC (hydroxyethyl cellulose) typically involves three main steps: alkalization, etherification, and post-treatment.
First, refined cellulose (such as wood pulp) is alkalized under alkaline conditions to produce alkaline cellulose.
Next, the alkaline cellulose undergoes an etherification reaction with ethylene oxide in the presence of a catalyst, introducing hydroxyethyl side chains. Finally, post-treatment, including neutralization, washing, filtration, centrifugation, and drying, yields the final HEC product.
During the manufacturing process, the factory launched:
1. Real-time monitoring DCS System: to protect viscosity, substitution, and consistency.
2. Quality Control: starts with the meticulous selection of raw materials extending throughout the whole production process.
Celix Hydroxyethyl Cellulose HEC could offer:
1. Good Film formation
2. Good Enzyme resistance
3. High Water retention
4. Perfect Surface activity
5. Pseudoplasticity
6. Good PH stability
7. Good Thickening & Binding Effect
The advanced testing techniques, like IR and GPC, provide trust in every batch by ensuring consistent product quality and dependable performance.
| Performance Property | Hydroxyethyl Cellulose (HEC) | Hydroxypropyl Methyl Cellulose (HPMC) |
| Primary Industry Focus | Water-based Paints, Coatings, Oil Drilling | Cement-based Mortars, Tile Adhesives |
| Enzymatic Resistance | Superior (Prevents paint viscosity loss) | Moderate |
| Color Acceptance / Compatibility | Excellent (No interference with pigments) | Standard |
| Thermal Gel Temperature | None (Soluble in cold & hot water without gelling) | Gels at 60°C – 75°C |
Celix offers surface-treated (delayed-solubility) HEC grades. These grades can be dispersed directly into cold water at neutral pH without immediate swelling. After complete dispersion, raising the pH to 8.0–9.0 triggers rapid hydration without clumping.
Yes. We provide free 500g to 1kg testing samples along with the complete Technical Data Sheet (TDS) and SDS.
HEC material is a hydroxyethyl cellulose, a non-ionic cellulose ether with water-soluble, thickening properties.
Supported by our 30,000-ton total annual cellulose capacity, Celix ensures stable bulk supply. Standard packaging is 25kg multi-layer PE-lined paper bags, available with custom OEM private labeling for global distributors.
HEC has hydroxyethyl groups; HPMC has methyl + hydroxypropyl groups. HPMC has the better thermal stability.
A: The standard dosage ranges from 0.3% to 0.5% of the total formulation weight. Higher viscosity grades (e.g., 100,000 mPa.s) require lower dosages to achieve the target thickener efficiency and spatter-resistance.
