Non-ionic, water-soluble cellulose ether engineered for thickening, rheology control, suspension stability, texture improvement, and formulation consistency in water-based and industrial systems.
LANDERCOLL HEC (Hydroxyethyl Cellulose, CAS 9004-62-0) is a high-performance, non-ionic, water-soluble cellulose ether designed for manufacturers who need reliable thickening, rheology control, suspension stability, texture improvement, water retention, and formulation consistency across water-based paints, coatings, personal care products, detergents, home care formulations, oilfield fluids, construction materials, adhesives, inks, and specialty industrial systems.
In water-based paint and coating systems, HEC is one of the most widely used cellulose ether thickeners — helping formulators control viscosity, flow, leveling, pigment suspension, brushing behavior, and storage stability within a single ingredient.
LANDERCOLL HEC is a non-ionic, water-soluble cellulose ether designed for manufacturers who need reliable thickening, rheology control, suspension stability, texture improvement, water retention, and formulation consistency across a wide range of water-based and industrial systems.
HEC is especially well-suited for water-based paints and architectural coatings, latex paint, personal care products, home care formulations, liquid detergents, oilfield fluids, selected construction materials, adhesives, inks, and other water-based industrial systems.
As a non-ionic polymer, HEC is compatible with a wide range of surfactants, pigments, fillers, salts, and pH conditions — making it a versatile and reliable thickener across diverse formulation environments.
HEC stands for Hydroxyethyl Cellulose. It is produced by reacting purified cellulose with ethylene oxide under controlled alkaline conditions. This reaction introduces hydroxyethyl groups (–OCH₂CH₂OH) onto the cellulose backbone, converting the insoluble natural polymer into a water-soluble, non-ionic cellulose ether. The degree of substitution — expressed as molar substitution (MS) of hydroxyethyl groups — influences solubility, viscosity development, and compatibility in different formulation systems.
Compatible with anionic, cationic, and non-ionic systems across a wide range of pH conditions and formulation environments.
Unlike HPMC and HEMC/MHEC, HEC contains no methoxyl groups and remains soluble in both cold and hot water.
Stable across a broad pH range — suitable for mildly acidic personal care products, alkaline construction systems, and high-salinity oilfield fluids.
One of the primary reasons HEC is the most widely used cellulose ether thickener in water-based architectural coatings.
HPMC and HEMC/MHEC are methyl cellulose ethers that contain methoxyl groups, which cause them to gel when heated above their gelation temperature. HEC contains only hydroxyethyl groups and no methoxyl groups — it does not exhibit thermal gelation, remaining soluble in both cold and hot water. This makes HEC particularly suitable for latex paint systems where thermal gelation behavior would be undesirable.
HEC's absence of thermal gelation and its strong compatibility with latex polymer systems are the primary reasons it is preferred over HPMC in water-based architectural coatings.
HEC delivers reliable thickening, rheology control, and suspension stability within a single non-ionic ingredient. Biodegradable, odorless, and free from animal-derived raw materials — with broad pH stability and ionic compatibility across paints, personal care, detergents, oilfield, and industrial systems.

HEC is a multifunctional cellulose ether that contributes several performance benefits simultaneously in most applications. Below is a structured overview of its primary functions across different water-based formulation types.
HEC forms a viscous, pseudoplastic solution — viscosity decreases under shear during mixing and application, and recovers at rest. This shear-thinning behavior supports easy brushing and rolling during paint application while maintaining stable in-can viscosity during storage. Supports product body in detergents and controlled texture in personal care.
HEC influences how a formulation flows, levels, sags, brushes, rolls, and recovers after application. In water-based paints, it directly affects brushing and roller feel, leveling behavior (how smoothly brush marks disappear), sag resistance on vertical surfaces, and spatter resistance during high-speed roller application.
In systems containing pigments, fillers, mineral particles, or insoluble active ingredients, HEC helps maintain uniform suspension and reduces settling or separation during storage and use. Critical in paints, textured coatings, personal care products with particles or actives, and oilfield fluids requiring suspension of weighting materials.
In selected construction and industrial applications, HEC helps retain water within the formulation, slowing water loss to porous substrates and to evaporation. Supports adequate hydration reactions, extends working time, and improves application consistency.
HEC helps maintain uniform viscosity, appearance, and product consistency during storage, transport, and use. Prevents phase separation, syneresis, and viscosity drift over time — contributing to longer shelf life and consistent product performance.
HEC acts as a protective colloid in water-based systems, helping stabilize dispersed particles and prevent agglomeration — relevant in latex paint systems for pigment and latex particle dispersion, and in personal care for stable emulsions and suspensions.
In personal care and home care products, HEC contributes to smooth, controlled, and user-friendly product texture — neither too thin and watery nor too heavy and sticky — delivering a clean, pleasant sensory profile that consumers respond well to.
HEC grade selection should always begin with the target formulation. Different applications require different balances of viscosity build, dissolution speed, flow behavior, storage stability, compatibility, suspension performance, and texture. The table below provides a structured reference for common application-to-grade matching.

Medium to high viscosity grades are typically used, with dosage in the range of 0.2%–0.8%.
Helps build viscosity, control flow, stabilize pigments and latex particles, and improve application behavior during brushing and rolling. Supports better in-can consistency and helps the paint spread more evenly and level more smoothly after application.
Texture coatings contain coarse aggregate particles and require stronger body, better suspension, and stable structure. High-viscosity HEC grades provide the necessary thickening and suspension performance to keep aggregate particles uniformly distributed and prevent slumping on vertical surfaces.
As a non-ionic polymer, HEC is compatible with the anionic and non-ionic surfactant systems commonly used in cleaning products, and it does not interfere with cleaning performance. In liquid detergent systems, HEC builds a smooth, stable viscosity profile that improves product appearance, pourability, and consumer perception of product quality.
It also helps maintain uniform product consistency throughout the shelf life and prevents phase separation or viscosity drift during storage.

Food · Detergents · Ceramics · Pharma · Oilfield · PaperHEC is the most commonly used cellulose ether due to its strong latex compatibility and absence of thermal gelation. It remains fully dissolved and functional across all temperature ranges encountered during paint production, storage, and application — including warm summer conditions where methyl cellulose ethers might approach their gelation temperature.
For drymix construction materials: HPMC and HEMC/MHEC are more commonly selected due to stronger water retention and workability performance in cement and gypsum systems. For pharmaceutical and food applications: HPMC is the most widely used with established regulatory acceptance. For food, ceramics, and detergent systems where an anionic thickener is acceptable: CMC may offer a cost-effective alternative.
LANDERCOLL HEC is supplied in industrial packaging suitable for transportation, storage, and production handling. HEC powder is hygroscopic and will absorb moisture from the environment if packaging is left open or storage conditions are inadequate. Proper storage conditions help maintain powder flowability, dispersion behavior, viscosity performance, and product stability throughout the shelf life.

HEC and HPMC are both non-ionic, water-soluble cellulose ethers, but they have different chemical structures. The most important practical difference is thermal behavior: HPMC contains methoxyl groups and gels when heated above its gelation temperature, while HEC contains only hydroxyethyl groups and remains soluble in both cold and hot water. HEC is preferred in latex paint and coating systems; HPMC is more widely used in construction, pharmaceutical, and food applications.
The right HEC grade depends on your application type, required viscosity level, pH range, surfactant system, pigment or filler content, electrolyte level, mixing method, hydration conditions, and final stability requirements. Contact LANDERCOLL with your application details, and our team can recommend suitable grade directions and support your formulation evaluation.
