Polyanionic cellulose (PAC) is a cellulose derivative that has been chemically modified to have anionic (negatively charged) groups attached to the cellulose backbone. These modifications enhance the solubility and stability of cellulose in various environments, allowing it to form gels, stabilize suspensions, and interact with various biological systems and materials.
Applications:
- Oil and Gas Industry: PAC is commonly used in drilling fluids as a viscosifying agent and to improve the stability of the fluid. It helps maintain borehole stability and minimizes the risk of wellbore collapse.
- Pharmaceuticals: Due to its biocompatibility and ability to form gels, PAC is used in some drug formulations and as an excipient in tablet formulations.
- Food Industry: As a food additive, PAC can function as a thickening agent and stabilizer in various food products.
- Cosmetics: It is used in cosmetic formulations for its thickening and stabilizing properties.
- Environmental Applications: PAC can be utilized in wastewater treatment processes as it can help in flocculation and removal of suspended solids.
- Biotechnology and Molecular Biology: In research, PAC can be used in various assays and applications requiring a stable gel matrix.
