China Suppliers Factory Wholesale HEC Hydroxyethyl Cellulose - Odorless, Tasteless, Non-Toxic Powder for Viscous Solutions
Product Overview
Hydroxyethyl Cellulose (hydroxyethyl cellulose) is a non-ionic water-soluble cellulose ether, usually appearing white to pale yellow in powder form.
Product Characteristics
✓
Good water solubility: It can be quickly dissolved in cold water to form a transparent and uniform solution.
✓
Thickening and stabilizing effect: Significantly increase the viscosity of the solution, improve the stability of the system, prevent precipitation and delamination.
✓
Pseudoplastic fluid characteristics: The solution has a high viscosity at low shear rate, and the viscosity decreases at high shear rate, which is convenient for construction and application.
✓
Salt resistance: It can still maintain good performance in a certain degree of salt solution.
✓
pH stability: Stable performance over a wide pH range.
Product Use
✦
Coatings field: As a thickening agent and rheological control agent, improve the construction performance and storage stability of coatings. For example, in water-based architectural coatings, the paint is easy to paint and the coating is uniform and smooth.
✦
Daily chemical industry: Used in shampoo, body wash, lotion and other products to increase consistency and stability.
✦
Oil extraction: As an additive to drilling fluid and completion fluid, it plays the role of increasing viscosity and reducing filtration loss.
✦
Pharmaceutical field: adhesive, suspension, etc., which can be used as tablets.
Production Process
It is generally prepared from cellulose by etherification reaction with ethylene oxide.

Frequently Asked Questions (FAQ)
What is Hydroxyethyl Cellulose (HEC)?
Hydroxyethyl Cellulose (HEC) is a non-ionic water-soluble cellulose ether. It is typically prepared from cellulose through an etherification reaction with ethylene oxide and appears as a white to pale yellow powder.
What are the primary characteristics of Hydroxyethyl Cellulose?
Its key characteristics include excellent water solubility in cold water, strong thickening and stabilizing effects, pseudoplastic fluid behavior (shear-thinning), salt resistance, and stable performance across a wide pH range.
In which fields is Hydroxyethyl Cellulose most commonly used?
It is widely used in coatings (as a thickener and rheological control agent), the daily chemical industry (shampoo, body wash, lotions), oil extraction (drilling and completion fluids), and the pharmaceutical field (tablet adhesives and suspensions).
What precautions should be taken when storing and using HEC?
During storage, protect it from moisture, sun exposure, and contact with strong oxidants. When preparing the solution, stir slowly to prevent clumping. The addition amount should be optimized based on the specific application system.
What are the typical technical indicators for Hydroxyethyl Cellulose?
Typical indicators include a molar substitution degree of 1.5-2.5, fineness (80 mesh sieve residue) ≤ 8.0%, dry weight loss rate ≤ 6.0%, ash content ≤ 10.0%, pH value of 5.0-9.0, and light transmittance ≥ 80%.
