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 ‘pinking' and ‘browning' 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
