Features Of Ashland NATROSOL 250HBR Hydroxyethylcellulose Thickener

  1. High-viscosity, low-shear thickening performance ideal for water-based systems requiring robust rheology control.

  2. Excellent compatibility with electrolytes, surfactants, and common preservatives in formulated products.

  3. Non-ionic nature ensures pH-independent viscosity stability across broad pH range (3–11).

  4. Provides outstanding suspension capability for pigments, fillers, and insoluble actives without gelation or syneresis.

  5. Easy cold-water dispersion with rapid hydration and minimal lump formation when properly pre-mixed.

Typical Applications Of Ashland NATROSOL 250HBR Hydroxyethylcellulose Thickener

  1. Architectural coatings — interior and exterior latex paints for sag resistance and brush/roller drag control.

  2. Industrial maintenance coatings — primers, sealers, and high-solids formulations requiring high-build rheology.

  3. Adhesives and construction mortars — tile adhesives, grouts, and dry-mix renders for open time and anti-sag performance.

  4. Personal care gels and cleansers — sulfate-free shampoos, hand soaps, and aqueous-based serums.

  5. Agrochemical suspensions — SC (suspension concentrate) and SE (suspo-emulsion) formulations for active ingredient stabilization.
