Features Of Ashland Natrosol 250 B TYPE Hydroxyethylcellulose Thickener

  1. High-viscosity, non-ionic thickener providing excellent pseudoplastic rheology and shear-thinning behavior.

  2. Outstanding water solubility with rapid hydration and minimal lump formation under moderate mixing conditions.

  3. Excellent compatibility with electrolytes, surfactants, and common preservatives used in aqueous formulations.

  4. Provides superior film-forming capability and improved suspension stability for insoluble actives and pigments.

  5. pH-insensitive viscosity performance across a broad range (pH 3–11), ensuring formulation robustness.

Typical Applications Of Ashland Natrosol 250 B TYPE Hydroxyethylcellulose Thickener

  1. Architectural coatings — interior and exterior latex paints requiring high sag resistance and brush/roll application performance.

  2. Industrial maintenance coatings — protective primers and topcoats where pigment suspension and spatter resistance are critical.

  3. Construction adhesives and tile grouts — enhancing open time, workability, and anti-sag properties.

  4. Agrochemical suspensions — stabilizing solid active ingredients in SC (suspension concentrate) and SE (suspo-emulsion) formulations.

  5. Personal care gels and cleansing bases — delivering clear, elegant rheology in sulfate-free and mild surfactant systems.
