Carboxymethylcellulose Calcium
(CDE REGISTRATION NO.: F2023000328)
Name: Carboxymethylcellulose Calcium
Other Name: Carmellose Calcium
CAS No.: 9050-04-8
Packaging: 1kg/bag/carton; 5kg/bag/carton; 20kg/bag/drum
Appearance:
White or yellowish white powder; hygroscopic after drying.
Practically insoluble in acetone, in ethanol (96 per cent) and in toluene. It swells with water to form a suspension.
Quality Standard: CP2020/USP2024/EP11.0/JP18

Features:
Carboxymethylcellulose Calcium is primarily used in tablets as a binder, diluent, and disintegrant. Although it is insoluble in water, it is an effective tablet disintegrant because it expands several times its original volume upon contact with water.
Applications:
| Dosage form | Application | Dosage |
| Oral solid preparations | Disintegrant | 1-5% |
| Oral solid preparations | Binder | 0.5-2% |
| Liquid preparations | Thickening Agent, Suspending Agent | 1%-5% |
| Topical Formulations | Thickening Agent, Suspending Agent | 1%-5% |
| Wound Dressings | Absorbent, Hemostatic Agent | 5%-15% |
Advantages:
■Carboxymethylcellulose Calcium is the only calcium-based disintegrant available worldwide.
■Carboxymethylcellulose Calcium can rapidly absorb water, swell, and disintegrate within a short time..
■Carboxymethylcellulose Calcium is suitable for both wet granulation and direct tableting processes.
■It is derived from natural materials, exhibiting good biocompatibility, non-toxicity, excellent disintegration properties, and biodegradability.
■High Stability: Stable against heat, light, air, and microbial degradation.
Incompatibilities
■CMC-Ca may react with certain drug components under acidic conditions (e.g., with chlorides or sulfates).
■High concentrations may affect tablet hardness.
Storage
Preserve in tight containers.
