Viscosity Modifier and Thickener
Soluble carboxymethylcelluloses are widely employed to increase the viscosity of aqueous solutions, improving the texture and stability of various formulations. They are crucial for thickening cosmetic products, food items, and industrial fluids.
Emulsion Stabilisation
This compound acts as an effective emulsifier, helping to create and maintain stable mixtures of immiscible liquids. It prevents phase separation in products ranging from pharmaceuticals to personal care items.
Dispersant for Carbon Structures
Carboxymethylcellulose sodium salt is utilised to create stable dispersions of carbon-based materials, such as carbon nanotubes. This ensures uniform distribution in composite materials and advanced formulations.
Biostructure Development
It plays a role in the creation of advanced biostructures, including biofilms, emulsions, and nanoparticles, particularly for applications in drug delivery systems.
