cross-linked carboxymethylcellulose

Cross-linked carboxymethylcellulose (CX-CMC) is a chemically modified derivative of cellulose, engineered to enhance its performance characteristics such as thermal stability, resistance to salt, and thickening efficiency. It is prized for its excellent water retention, viscosity control, and stabilizing properties. In pharmaceutical applications, CX-CMC is utilized in ophthalmic solutions for conditions like Dry Eye Disease, where it provides viscoelastic, hydrating, and wound healing benefits. It also serves as a biosynthetic filler for soft-tissue augmentation, offering volume and structural support. Additionally, it is widely used as an excipient in various pharmaceutical formulations, including as a disintegrant in tablets and in advanced drug delivery systems.
