Features Of Ashland HEC-250 Hydroxyethyl Cellulose

  1. High-viscosity, water-soluble polymer delivering excellent thickening and rheology control in aqueous systems.

  2. Outstanding salt tolerance and compatibility with surfactants, electrolytes, and common industrial additives.

  3. Non-ionic nature ensures broad pH stability (pH 3–11) and minimal interaction with cationic or anionic components.

  4. Provides superior film-forming capability and improved suspension of insoluble particles in liquid formulations.

  5. Easily dispersible with low gel lumps, enabling efficient cold-water hydration and simplified manufacturing handling.

Typical Applications Of Ashland HEC-250 Hydroxyethyl Cellulose

  1. Architectural coatings: water-based paints and interior/exterior emulsion paints.

  2. Construction mortars and tile adhesives requiring workability, water retention, and sag resistance.

  3. Personal care products: shampoos, conditioners, and gels where clarity, viscosity stability, and mildness are critical.

  4. Agrochemical formulations: suspension concentrates (SC) and emulsifiable concentrates (EC) for uniform active ingredient dispersion.

  5. Oilfield fluids: completion and fracturing fluids requiring viscosity enhancement and fluid loss control.
