Polyvinylpolypyrrolidone (PVPP) is a polyphenol adsorbant.
The Polyvinylpolypyrrolidone treatment can complement a protein adsorption treatment

But Polyvinylpolypyrrolidone can also be used as the only treatment.
Polyvinylpolypyrrolidone can be added to the maturation tank or dosed online to beer going to filtration.

Polyvinylpolypyrrolidone (polyvinyl polypyrrolidone, 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.

Polyvinylpolypyrrolidone 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.

Polyvinylpolypyrrolidone can be used as a drug, taken as a tablet or suspension to absorb compounds (so-called endotoxins) that cause diarrhea. (Cf. bone char, charcoal.)
Polyvinylpolypyrrolidone is also used as a fining to extract impurities (via agglomeration followed by filtration).

Polyvinylpolypyrrolidone is used in winemaking.
Using the same principle Polyvinylpolypyrrolidone is used to remove polyphenols in beer production and thus clear beers with stable foam are produced.

Polyvidone is used as:
- a diluent in colour additive mixtures for marking food

-in coatings on fresh citrus fruits

-as a clarifying agent for beer, wine and vinegar

-as a tableting adjuvant

A cross-linked form of PVP is also used as a disintegrant (see also excipients) in pharmaceutical tablets.
Polyvinylpolypyrrolidone is also known as cross-linked polyvinyl pyrrolidone, Polyvinyl Polypyrrolidone (PVPP), crospovidone, crospolividone.

Basically, Polyvinylpolypyrrolidone is a highly cross-linked version of PVP, which makes it insoluble in water but it still absorbs water and swells very rapidly and generate a swelling force.
That is why Polyvinylpolypyrrolidone can be used a disintegrant in tablets.

Polyvinylpolypyrrolidone is also used to bind impurities to remove them from solutions.
Polyvinylpolypyrrolidone is also used as a fining to extract impurities (via agglomeration followed by filtration).

Using the same principle it is used to remove polyphenols in beer production and thus clear beers with stable foam are produced.
Polyvinylpolypyrrolidone can be used as well as a drug taken as a tablet or suspension and it absorbs compounds (so called Endotoxins) causing diarrhoea.

As a food additive, PVP is a stabilizer and has E number E1201.
Polyvinylpolypyrrolidone is E1202.
Polyvinylpolypyrrolidone is also used in the wine industry as a fining agent for white wine.

Other references state that as polyvinyl pyrrolidone and its derivatives are fully from mineral synthetic origin. Therefore, its use in the production should not be a problem for vegans.
PVP is soluble in water and other polar solvents.

In water Polyvinylpolypyrrolidone has the useful property of Newtonian viscosity.
When dry Polyvinylpolypyrrolidone is a light flaky powder, which readily absorbs up to 40% of its weight in atmospheric water.

In solution, Polyvinylpolypyrrolidone has excellent wetting properties and readily forms films.
This makes Polyvinylpolypyrrolidone good as a coating or an additive to coatings.

PVP was first synthesized by Prof. Walter Reppe and a patent was filed in 1939 for one of the most interesting derivatives of acetylene chemistry.
PVP was initially used as a blood plasma substitute and later in a wide variety of applications in medicine, pharmacy, cosmetics and industrial production.

Polyvinylpolypyrrolidone (PVPP, crospovidone) is a highly cross-linked modification of PVP.
Polyvinylpyrrolidone (PVP) is a water-soluble polymer made from the monomer N-vinylpyrrolidone:.

One such commercial product is called Polyclar.
Polyvinylpolypyrrolidone 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.
Polyvinylpolypyrrolidone has E number code E1202 and is used as a stabiliser.

Insoluble polyvinylpolypyrrolidone is a polymer poly[1-(2-oxo-1-pyrrolidinylethylene] reticulated to render it insoluble.
Polyvinylpolypyrrolidone is made by polymerisation of N-vinyl-2-pyrrolidone in the presence of different catalysers (for example sodium hydroxide) or in the presence of N'Ndivinylimidazolidone.

Polyvinylpolypyrrolidone fixes the polyphenols in wines; this adsorption depends on the rate of polymerisation.
Polyvinylpolypyrrolidone's application rate is limited.

Polyvinylpolypyrrolidone is Light powder, white and creamy white.
Polyvinylpolypyrrolidone is Insoluble in water and in organic solvents.

Polyvinylpolypyrrolidone is Insoluble in strong acid minerals and in alkaly.
Polyvinylpolypyrrolidone is used as an excipient to prepare samples for subsequent analysis steps.

Polyvinylpolypyrrolidone has a wide range of applications, especially in the beverage industry.
Polyvinylpolypyrrolidone is used to pre-treat samples such as juices with strong colors

Polyvinylpolypyrrolidone 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 Polyvinylpolypyrrolidone 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.

Polyvinylpolypyrrolidone's Functions:
*Binder / Stabilizer: Polyvinylpolypyrrolidone Retains the physical characteristics of food/cosmetics and ensure the mixture remains in an even state.

*Emulsifier: Polyvinylpolypyrrolidone Allows water and oils to remain mixed together to form an emulsion.

*Gelling Agent / Thickener: Polyvinylpolypyrrolidone Increases the viscosity by thickening the liquid to give it more texture
