The Kollidon® CL family is the industry’s widest portfolio of super-disintegrants and dissolution enhancers. These highly functional cross-linked PVP polymers ensure that active ingredients are released from any solid dosage form at exceptionally high speed. In addition, they improve bioavailability of certain poorly soluble APIs.
| Grades | K Value | Molecular Weight | Application |
| Kollidon CL | Type A | 90-130 µm | Used as super-disintegrants and dissolution enhancers. These highly functional cross-linked PVP polymers ensure that active ingredients are released from any solid dosage form at exceptionally high speed. In addition, they improve bioavailability of certain poorly soluble APIs. |
| Kollidon CL F | Type A | 20-40 µm | Due to the balance of strong disintegration and optimal surface homogeneity our crosspovidone Kollidon® CL-F is your first choice tablet disintegrant. The super-disintegrant is specifically suitable for use in small tablets to fasten disintegration and dissolution. Kollidon® CL-F can also be used in wet granulation processes, when large amount of granulation liquids are needed. |
| Kollidon CL SF | Type B | 10-30 µm | The finest grade of water-insoluble crospovidone disintegrant available in the market for small and orally disintegrating tablets. It provides smooth tablet surface and cream-like mouth feel. Kollidon® CL-SF strongly improves tablet hardness and has a strong ability to absorb water. |
| Kollidon CL M | Type B | 3-10 µm | Kollidon® CL-M is used as a stabilizer for oral and topical suspensions and to improve the drug release characteristics of tablets, capsules or granules. Our disintegrant with micronized particles, delivers a slight disintegration functionality when used as binder. The crosspovidone is also used as pore former in some formulations. |
