Nourisi ®Polyanionic Cellulose (PAC) CAS 9004-32-4 Polyanionic Cellulose (PAC) is a high-performance, water-soluble anionic polymer derived from the chemical modification of natural cellulose . The chemical formula is (R)nOCH₂COONa, with CAS registry number 9004-32-4 .
PAC appears as a cream white to off-white free-flowing powder that is odorless, non-toxic, and readily soluble in both cold and hot water . It is a cellulose ether derivative with a high degree of substitution (DS ≥ 0.9), which significantly enhances its water solubility, electrolyte resistance, and thermal stability compared to conventional Carboxymethyl Cellulose (CMC) .
The product is available in multiple viscosity grades—High Viscosity (PAC-HV) and Low Viscosity (PAC-LV) —each designed to meet specific application requirements ranging from fluid loss control in drilling fluids to thickening in food and pharmaceutical formulations
| Items | Specification |
| CAS No. | 9004-32-4 |
| Appearance | Fine, yellow white cream powder, no starch or starch derivative |
| Moisture Content | Max 10% |
| Apparent Viscosity | Max 40 mPa.s ,600r/min/ |

Nourisi ®Polyanionic Cellulose (PAC) CAS 9004-32-4 is a versatile product used in numerous industries, often as a high-performance substitute for CMC
Nourisi ®Polyanionic Cellulose (PAC) CAS 9004-32-4 is extensively used as a fluid loss control agent and viscosifier in water-based drilling fluids for both onshore and offshore operations .
● Key Functions:
Fluid Loss Control: Forms a thin, low-permeability filter cake across porous rock formations, reducing filtrate invasion and preventing formation damage
Shale Inhibition: Encapsulates drill solids and exposed shales, reducing clay dispersion and inhibiting swelling of the borehole
Rheology Control: Improves viscosity and yield point for effective hole cleaning and cuttings transport
Salt Tolerance: Maintains performance in seawater, saltwater wells, and saturated brine systems
● Typical Dosage:
Drilling fluids: 0.2% – 0.8% by weight of drilling fluid
Workover fluids: Low-solid-phase formulations that do not harm production zones
Fracturing fluids: Provides fast gelation and excellent sand-carrying capacity; especially effective in low-permeability formations
● Suitable Conditions:
Saltwater wells and offshore oil drilling
Deep-well drilling with high temperatures
High-salinity environments requiring stable rheology
Nourisi ®Polyanionic Cellulose (PAC) CAS 9004-32-4 serves as a water retention agent and workability enhancer in cement, mortar, and gypsum-based products .
● Key Functions:
Improves water retention for complete binder hydration
Enhances workability and anti-settling properties
Reduces cracking caused by rapid drying
● Typical Dosage:
Cement slurries: 0.1% – 0.5% by weight of cement
Mortars and plasters: As required for specific formulations
Coatings & Paints：Thickener, rheology modifier, film-forming agent
Ceramics：Suspending agent, binder, water retention agent
Textiles：Light yarn sizing agent (replaces starch); fabric finishing agent
Paper Industry: Improves longitudinal strength, smoothness, oil resistance, and ink absorption
Nourisi ®Polyanionic Cellulose (PAC) CAS 9004-32-4 exhibits extraordinary and useful properties：
Water Solubility: Readily dissolves in fresh water, seawater, and brine systems without special mixing equipment
Salt Tolerance: Exceptional stability in high-salinity environments, including saltwater wells and offshore drilling
Thermal Stability: Maintains performance at elevated temperatures; short-term resistance up to 150°C
Fluid Loss Control: Forms low-permeability filter cake to reduce filtrate invasion in drilling applications
Rheology Control: Effective viscosifier and rheology modifier
