Features Of Lotte B15K Hydroxyethyl Cellulose

  1. High viscosity build and excellent pseudoplastic rheology for superior suspension and sag resistance.

  2. Outstanding water solubility and rapid hydration without clumping, even in cold water.

  3. Excellent compatibility with electrolytes, surfactants, and common industrial preservatives.

  4. Stable performance across a broad pH range (3–11), ensuring formulation robustness.

  5. Non-ionic nature minimizes interference with active ingredients in sensitive formulations.

Typical Applications Of Lotte B15K Hydroxyethyl Cellulose

  1. Architectural coatings — interior and exterior latex paints for leveling, spatter resistance, and brushability.

  2. Tile adhesives and cement-based mortars — improves workability, open time, and water retention.

  3. Personal care formulations — stabilizes emulsions and provides gentle thickening in shampoos and body washes.

  4. Agrochemical suspensions — enhances particle dispersion and prevents settling of active ingredients.

  5. Oilfield drilling fluids — functions as a viscosifier and fluid-loss control additive in water-based systems.
