Features Of Dow CELLOSIZE QP440H Hydroxyethyl Cellulose

  1. High viscosity performance in aqueous systems with excellent pseudoplastic rheology.

  2. Outstanding salt tolerance and compatibility with common electrolytes and surfactants.

  3. Non-ionic nature ensures stability across broad pH range (pH 2–12) without precipitation.

  4. Excellent film-forming ability and adhesion to diverse substrates including concrete, metal, and plastics.

  5. Easy dispersion and rapid hydration without lump formation when added with proper mixing.

Typical Applications Of Dow CELLOSIZE QP440H Hydroxyethyl Cellulose

  1. Water-based architectural coatings and interior/exterior paints.

  2. Cementitious tile adhesives and grouts for enhanced open time and sag resistance.

  3. Oilfield completion fluids and fracturing additives requiring thermal and shear stability.

  4. Personal care formulations such as shampoos, conditioners, and body washes for viscosity control and clarity.

  5. Pharmaceutical suspensions and topical gels where non-ionic, GRAS-compatible thickeners are required.
