Product Description:

Polyvinylpolypyrrolidone (polyvinylpolypyrrolidone, PVPP, crospovidone, crospolividone or E1202) is a highly cross-linked modification of polyvinylpyrrolidone (PVP).

The cross-linked form of PVP is used as a disintegrant (see also excipients) in pharmaceutical tablets. PVPP is a highly cross-linked version of PVP, making it insoluble in water, though it still absorbs water and swells very rapidly generating a swelling force. This property makes it useful as a disintegrant in tablets.

PVPP can be used as a drug, taken as a tablet or suspension to absorb compounds (so-called endotoxins) that cause diarrhea. It is also used as a fining to extract impurities (via agglomeration followed by filtration). It is used in winemaking. Using the same principle it is used to remove polyphenols in beer production and thus clear beers with stable foam are produced. One such commercial product is called Polyclar. PVPP forms bonds similar to peptidic bonds in protein (especially, like proline residues) and that is why it can precipitate tannins the same way as proteins do.

Povidone xl is short for polyvinylpolypyrrolidone which is a polymerized and water/beer insoluble version of the soluble compound PVP (polyvinylpyrrolidone), a nylon-type polymer that has an even higher affinity for chemical bonding with polyphenols than the proteins present in beer have. This gives PVPP excellent properties as a chemical stabilizer for beer. If finely granulated, high surface area PVPP is dispersed in beer, a very high proportion of the dissolved polyphenols in the beer will bind to the PVPP particles, subsequently to be filtered out. Brewers wish to remove these polyphenols because they will otherwise with time react with beer proteins, forming insoluble complexes that will make the beer hazy. This type of stabilizer is referred to as an adsorbent.
