Cross linked polyvinylpyrrolidone PVPP powder, also called Crospovidone 25249-54-1 CAS 25249-54-1, is a white or milky white free-flowing powder that is easily hygroscopic, odorless or slightly odorless. It is insoluble in water, alkali, acid and commonly used organic solvents. It has strong swelling properties and the ability to complex with many types of substances.

PVPP is considered the first choice disintegrant for high-end tablet drugs, especially suitable for the formulation of instant and chewable tablets. It has been included in the United States Pharmacopeia and the European Pharmacopoeia. In addition, food-grade products are also widely used in the beer/wine/beverage industry.

Beverage and brewing industry:

PVPP is an insoluble, high molecular weight cross-linked compound with excellent adsorption properties. PVPP can be used in the beverage and brewing industries very safely and efficiently.

The application of PVPP in beer production is mainly reflected in improving the stability of beer colloid solution. By adding PVPP, the stability of beer can be enhanced to prevent precipitation and turbidity, thus improving the taste and quality of beer. PVPP has a similar effect to formaldehyde, so it can be used as a stabilizer to replace formaldehyde to solve the precipitation problem in beer. During the production process, PVPP is separated from polyphenols by complexing and adsorbing them to maintain the clarity of beer. The use of this material, especially in European countries, has gradually replaced formaldehyde.

Pharmaceutical industry:

PVPP has excellent properties as a disintegrant.
