Kollidon CL SF

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-SF is the finest BASF grade for disintegration applications. It has advantages when it comes to special applications, for example oral fast dispersible tablets. The main reason is a reliable disintegration power in combination with a very smooth cream-like mouth feel. Due to its strong ability to absorb water, Kollidon® CL-SF is also used as a regular disintegrant in wet granulation processes with large amounts of solvent use. Kollidon® CL-SF has the highest solvent (water/ethanol, etc.) uptake capacity of all crospovidones produced by BASF. Moreover, Kollidon® CL-SF gives rise to fewer defects on the tablet surface after storage. Like soluble products crospovidone improves the bioavailability of some hardly soluble actives ingredients. The insoluble grades of Kollidon® (Crospovidone) are manufactured by a polymerization process that yields crosslinked insoluble polyvinylpyrrolidone in the form of a “popcorn” polymer. The polymerisation is performed using an aqueous system. Neither organic solvents nor radical starters are involved at any stage.
