Nourisi ®Poly anionic cellulose is a water-soluble, high-purity anionic polymer derived from natural cellulose through chemical etherification. It appears as a white to off-white, free-flowing powder that is odorless, non-toxic, and readily soluble in both cold and hot water .
Nourisi ®Poly anionic cellulose is produced by introducing carboxymethyl groups (−CH₂COONa) onto the cellulose backbone, resulting in a sodium salt form with a high degree of substitution (DS). This chemical modification significantly enhances the polymer's water solubility, electrolyte tolerance, and thermal stability, making PAC far more effective than conventional Carboxymethyl Cellulose (CMC) in demanding environments .
Unlike standard CMC, Nourisi ®Poly anionic cellulose features a more uniform substitution pattern and higher purity, which translates to superior performance consistency and lower dosage requirements — typically only 30–50% of the amount needed when using conventional CMC .

Nourisi ®Poly anionic cellulose delivers consistent, reliable, and high-performance characteristics across demanding applications. Whether for deep-well drilling under extreme conditions or precision formulation in food and pharmaceuticals, PAC provides the functional versatility and process stability that modern industries demand.
Poly anionic cellulose is a core additive in water-based drilling fluids for both onshore and offshore operations. Its primary functions include:
Fluid Loss Control
Poly anionic cellulose forms a thin, low-permeability filter cake on the borehole wall, significantly reducing filtrate invasion into permeable formations. This prevents formation damage, maintains wellbore stability, and reduces the risk of differential sticking .
Rheology Modification & Hole Cleaning
Poly anionic cellulose increases the viscosity and yield point of drilling fluids, improving the suspension and transport of drill cuttings to the surface. This ensures effective hole cleaning, particularly in deviated and horizontal wells .
Shale Inhibition & Wellbore Stabilization
Poly anionic cellulose encapsulates drill solids and exposed shales, reducing clay dispersion and protecting water-sensitive formations from hydration damage. This improves wellbore integrity and reduces the risk of collapse in reactive shale formations .
Workover & Completion Fluids
Poly anionic cellulose is used in low-solids workover fluids that minimize formation damage. These fluids provide low fluid loss and do not block production zones due to solid invasion .
Fracturing Fluids
Poly anionic cellulose-based fracturing fluids gel quickly, exhibit excellent proppant-carrying capacity, and can be prepared on-site. They perform particularly well in low-permeability formations .
PAC serves as a high-performance water retention agent and thickener in construction materials:
Cement slurries and grouts – Improves water retention, ensuring complete hydration of binders
Tile adhesives – Enhances workability and open time
Mortars and plasters – Prevents cracking due to rapid drying
Self-leveling compounds – Controls rheology for proper flow and leveling
Thickener, rheology modifier, anti-sag agent
Binder, suspending agent, glaze stabilizer
Sizing agent, printing paste thickener
Nourisi ®Poly anionic cellulose exhibits extraordinary and useful properties：
Water Solubility: Dissolves rapidly in fresh water, seawater, and saturated brine without requiring special mixing equipment
Pseudoplasticity: Exhibits strong pseudoplastic flow characteristics, beneficial for pumping and placement
Salt Tolerance: Exceptional stability in high-salinity environments, including saturated salt solutions
Thermal Stability: Maintains performance up to 120°C – 149°C (250°F – 300°F), depending on grade and formulation
pH Stability: Effective across a wide pH range (approximately 4 to 12)
Bacterial Resistance: Resists enzymatic degradation; does not require preservatives or biocides in most applications
Film-Forming Ability: Forms flexible, durable films when dried
Biodegradability: Environmentally friendly; breaks down naturally over time
