Poly Anionic Cellulose (PAC) is a water-soluble polymer derived from cellulose, commonly used in various industries due to its unique properties like high stability, viscosity control, and film-forming ability.

1. Oil and Gas Industry (Drilling Fluids)

• Main Use: PAC is widely employed as a viscosifier and fluid loss control agent in water-based drilling fluids (muds) during oil and gas exploration.
• Why: It improves the rheological properties of the mud, stabilizes shale formations, and reduces filtration loss by forming a thin, impermeable filter cake on the borehole wall.
• Types: Available in low-viscosity (PAC-LV) and high-viscosity (PAC-HV) grades, depending on the drilling requirements.

2. Food Industry

• Main Use: Acts as a thickener, stabilizer, and emulsifier in food products.
• Examples: Used in ice creams, sauces, bakery products, and beverages to enhance texture and prevent separation.
• Why: It’s non-toxic, biodegradable, and compatible with food-grade standards (when purified to meet regulations like FDA or EU guidelines).

3. Pharmaceuticals

• Main Use: Serves as a binder, disintegrant, or thickener in tablet formulations and liquid suspensions.
• Why: Its biocompatibility and ability to control drug release make it valuable in medical applications.

4. Construction Industry

• Main Use: Added to cement, mortar, or gypsum-based products as a water-retaining agent and workability enhancer.
• Why: Improves adhesion, reduces cracking, and enhances the consistency of mixtures.

5. Paper and Textile Industry

• Main Use: Used as a sizing agent or coating in paper production and as a thickener in textile printing pastes.
• Why: Enhances surface strength in paper and ensures uniform dye application in textiles.

6. Cosmetics and Personal Care

• Main Use: Functions as a stabilizer and thickener in creams, lotions, and shampoos.
• Why: Provides a smooth texture and improves product stability under varying temperatures.

Key Properties Enabling These Uses:

• High water solubility and binding capacity.
• Resistance to salts and temperature changes (especially in drilling fluids).
• Biodegradability and eco-friendliness in certain applications.
• Adjustable viscosity based on molecular weight and degree of substitution.
