 PVP-P |
| CTFA: | POLYVINYLPOLYPYRROLIDONE ( Abbreviated to be PVP-P) | | CAS No. : | 25249-54-1 |
| Chemical Structure: | Polyvinylpyrrolidone crosslinked |  |
| General description: | PVP-P behaves as a white or creamy white powder with faint characteristic odor, which is easily hydrophilic and capable of complex with such substance as phenol, etc. It is completely insoluble with relatively high crosslink density and does not form gels that can impede disintegration, dissolution and drug release. It was accepted into Ph Eur 5.0 and USP/NF28th. |

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
