PVPP/ Insoluble PVP/ Crosslinked PVP/ Copovidone
Cas No.: 25249-54-1/9003-39-8
Cross Povidone is often called as crosslinked PVP, or insoluble PVP. It appears as white or light yellow, free flowing hygroscopic powder, odorless or with faint characteristic odor. It is insoluble in water, alkali, acid and common organic solvents. It has strong swellability and can complex with polyphenols, carboxylic acid and other compounds with low molecular weight.

Application
1. Clarifier and stabilizer:
In the beverage industry:
PVP is used as a clarifying agent, especially in the production of wine and beer. PVP can effectively remove suspended particles, proteins and polyphenols, reduce turbidity, and thus improve the transparency and stability of the beverage. This clarifying action not only improves the appearance of the drink, but also enhances its taste, making the final product clearer and more palatable.
In drinks such as green tea:
PVP can help maintain the clarity of the drink and prevent turbidity. It works by binding with polyphenolic compounds to form insoluble precipitates, thereby removing ingredients that affect the color and taste of the drink.
2.Other applications:
PVPP belongs to insoluble cross polymer, it has special netty capability structure and also repair the application limitation of PVP excellent solubility. It is not soluble in acid, alkali and common organic solvent, PVP is opposite. PVPP has good physiological security, water absorption, insolubility and complexation capabilities. It can be widely used in pharmaceutical, food, personal care, feed field, etc.
In the biological pharmaceutical field:
PVPP has good physiologic inertia and biological compatibility characteristics. It can be used as disintegration agent, medicine slow-releasing carrier and hemodialysis film, etc. After PVPP absorb water and it makes tablet(capsule) bear very high pressure, then disintegrate small incalculable grain, it improved biological availability of body.
In personal care industry:
PVPP can be used as moisture-preserving agent of top grade cosmetics, it can moisten the skin, maintain the aroma, ease pain and decrease pungency. In the toothpaste PVPP can clear the mouth, diminish inflammation.
Packing and Storage
20kg/drum,it should be reserved in dry place under th e room temperature and avoid sunshine.
