Kollidon® CL-F

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-F is the perfect alternative when formulators are looking for a disintegrant with strong disintegration power in combination with a smooth tablet surface and pleasing haptic properties. The water-insoluble crospovidone Kollidon® CL-F improves tablet hardness. Tablet containing Kollidon® CL-F do not tend to form rough surfaces when stored under humid conditions. Like the soluble products crospovidone improves the bioavailability of some hardly soluble actives and it can be used in wet granulation processes, when large amount of granulation liquids are required.

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.

Kollidon® CL-F – First Choice Superdisintegrant

  • Strong disintegration power in combination with a smooth tablet surface
  • Ideal for small tablet formulation
  • Suitable for wet granulation processes
  • Bioavailability increase of selected hardly soluble active ingredients
  • Consistently high quality for reliable performance and formulation stability

The insoluble Kollidon® CL-grades possess a number of useful properties for pharmaceutical products.

  • Improvement of tablet disintegration through predictable swelling without gel-formation
  • Swelling properties paired with particle size distribution make the fine Kollidon® CL-grades work efficiently in fast disintegrating formulations
  • In contrast to other disintegrants the Kollidon® grades improve the release and the bioavailability of drugs through complex formation
  • Kollidon® grades feature selective adsorption of polyphenols by complex formation
  • Kollidon® grades feature selective complex formation with some endotoxins

Direct Compression

Direct compression (DC) is the most economic way to produce a tablet as it is the shortest and most direct way to get from powder mix to final dosage form. BASF offers all functional excipients to successfully develop a DC process for your drug, including key elements like appropriate binder and lubricant.

Hot Melt Extrusion

Hot-melt extrusion has been used in the plastics & food industries for decades. In the 1980s, BASF became the first company to apply it to the production of pharmaceuticals for enhancing the solubility and bioavailability of poorly soluble actives. Today, HME is an accepted process for creating solid dispersions of APIs.

Wet Granulation

BASF offers the key functional materials required to achieve great wet granulation results.

Spray Drying

Spray drying is an established technology in the pharmaceutical industry to create amorphous, soluble forms of active ingredients. Key for a successful process is the use of the right functional polymer to ensure a stable solid dispersion. BASF offers a wide range of functional polymers to choose from, along with all other excipients typically used in the formulation.

Melt Granulation

Melt granulation is a great process option in a formulators' biovailability enhancement arsenal. A meltable binder is used to agglomerate drug and other ingredients to reduce recrystallization potential through separation. BASF offer all functional materials required for a successful formulation using melt granulation.

Related Special Applications

Orally Disintegrating Tablets (ODT)

Orally disintegrating tablets (ODT), are an innovative solid oral dosage form that is becoming more and more important in the pharmaceutical market, both for prescription and over-the-counter medications. In contrast to classical tablets, ODTs are specifically designed to disintegrate directly in the patient's mouth.
