High viscosity performance in low-shear aqueous systems, enabling excellent suspension and thickening efficiency.
Consistent batch-to-batch rheological behavior due to stringent Ashland manufacturing controls and purified cellulose feedstock.
Excellent salt tolerance, maintaining viscosity stability in formulations containing electrolytes up to 2% NaCl (w/w).
pH-stable across broad range (pH 5–10), supporting compatibility with common acids, bases, and buffering systems.
Non-ionic associative character minimizes interference with cationic surfactants and polymers in complex formulations.
Water-based architectural coatings — providing sag resistance and roller spatter control.
Tile adhesive mortars — enhancing open time, workability, and vertical slip resistance.
Oilfield cementing slurries — acting as a fluid loss additive and rheology modifier under high-temperature conditions.
Pharmaceutical oral suspensions — serving as a suspending and stabilizing agent compliant with USP/NF monograph requirements.
Textile printing pastes — delivering sharp pattern definition and pigment retention on fabric substrates.
