Hydroxyethyl Cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose through chemical modification.
It is widely used as a thickener, stabilizer, binder, and film-forming agent in various industries due to its excellent rheological properties, biocompatibility, and chemical stability.
HEC is synthesized by reacting alkali cellulose with ethylene oxide, resulting in hydroxyethyl substitution on the cellulose backbone.
The degree of substitution (DS) and molar substitution (MS) determine its solubility, viscosity, and performance in different applications.
High Water Retention – Excellent moisture retention in coatings, adhesives, and construction materials.
Pseudoplastic Rheology – Provides shear-thinning behavior, ideal for paints and cosmetics.
Thermal Stability – Stable under high-temperature processing (up to 80°C).
Salt Tolerance – Performs well in high-electrolyte environments (e.g., detergents).
pH Stability – Effective in both acidic (pH 2) and alkaline (pH 12) conditions.
Film Formation – Forms flexible, transparent films in personal care products.
