POLYVINYLPOLYPYRROLIDONE (PVPP)
Main Application:
Beverage industry:
PVP-P can be used in improving the quality and extends the shelf-life of beer by absorbing the polyphenyls and tannoids. Prevention of ĄŽpinking' and ĄŽbrowning' reactions in white and sparkling wines. Enhanced aroma and flavor in red wines.
PVP-P is a cost-effective and safe treatment in beer industry that:
Completely insoluble in beer
Applicable to all types of beer
Higher efficacy - lower dosage
Easy to use and excellent handling characteristics
Insoluble process aids, with wide regulatory approval
No negative impact on foam, flavor or other quality parameters
Improved dispersion and sedimentation characteristics
Longer filter run lengths compared to silica alone
Uses existing plant equipment
Pharmaceutical Industry:
Provide rapid disintegration in a wide range of oral solid dosage formulations and processes. Especially in the following areas:
In wet granulation tablet processes;
Ideally suited for use with poorly compressible drug actives and in direct compression tablet processes.
Outstanding performance in manufacturing ionic, acidic and alkaline drug actives
Quick dissolve and chewable tablets
Treat gastrointestinal disorders and as an anti-diarrhea agent.
Furthermore, PVP-P can also be used to improve solubility, and hence, enhance bioavailability in not only human but also veterinary applications
