Industrial Applications of CROSCARMELLOSE SODIUM
| Industry | Application | Process |
|---|---|---|
| Pharmaceuticals | Tablet disintegrant | Added during wet granulation or direct compression; rapidly absorbs water and swells to disrupt tablet structure, enabling rapid disintegration |
| Pharmaceuticals | Excipient for sustained- or controlled-release formulations | Used in combination with polymeric materials (e.g., HPMC); drug release rate is controlled by adjusting crosslinking density |
| Food | Thickener and stabilizer | Applied in dairy products and plant-based beverages to improve texture and prevent phase separation; typically incorporated via cold-water dispersion |
| Cosmetics | Thickener and suspending agent | Used in emulsions and creams to provide viscosity and physical stability; generally dispersed in the aqueous phase at room temperature, then dissolved by heating to 60–70°C |
| Medical devices | Component of absorbable hemostatic materials | Formulated with gelatin, oxidized cellulose, or similar agents into hemostatic sponges or powders; promotes platelet aggregation via a physically crosslinked network |
Manufacturing Quality Control of CROSCARMELLOSE SODIUM
| Detection Item | Common Analytical Method | Method Overview |
|---|---|---|
| Sodium Content | Flame Photometry | Quantifies sodium ions based on characteristic emission intensity at 589 nm in a flame. |
| Carboxyl Group Content | Acid-Base Titration | Determines carboxyl groups by titration with standardized NaOH after acidification and back-titration. |
| Degree of Substitution (DS) | Acid-Base Titration | Calculates DS from carboxyl content and dry weight, assuming stoichiometric equivalence per anhydroglucose unit. |
| Loss on Drying | Gravimetric Method (Oven Drying) | Measures weight loss after drying at 105 C to determine moisture and volatile content. |
| pH of 1% Aqueous Dispersion | Potentiometric pH Measurement | Determines hydrogen ion activity using calibrated pH electrode in standardized suspension. |
| Heavy Metals (as Pb) | Atomic Absorption Spectroscopy (AAS) | Quantifies lead and other heavy metals by atomic absorption at element-specific wavelengths. |
| Residue on Ignition | Gravimetric Method (Sulfated Ash) | Measures inorganic residue mass after high-temperature ignition following sulfuric acid treatment. |
| Viscosity (4% Dispersion) | Rotational Viscometry | Measures resistance to flow under controlled shear rate using spindle-type viscometer. |
| Particle Size Distribution | Laser Diffraction | Determines size distribution by analyzing angular scattering pattern of laser beam passing through dispersed sample. |
| Microbial Limits | Membrane Filtration and Plate Count | Quantifies aerobic microorganisms by filtration, membrane transfer to agar media, and colony enumeration. |
| Chloride Content | Potentiometric Titration with AgNO3 | Determines chloride ions via argentometric titration using silver nitrate and silver indicator electrode. |
| Identification (FTIR Fingerprint) | Fourier Transform Infrared Spectroscopy | Confirms molecular structure by matching characteristic absorption bands (e.g., COO-, OH, C-O) to reference spectrum. |
