Crospovidone is often called as crosslinked PVP, or insoluble PVP. It appears as white or off-white, free flowing hygroscopic powder, odorless or with faint characteristic odor, insoluble in water, alkali, acid and common organic solvents. It has strong expandability and complexing ability with polyphenols, carboxylic acid and other compounds with low molecular weight.
Application
Belonging to insoluble cross polymers, Crospovidone has a special netlike micro-structure and also break through the application limitation of PVP because of its excellent solubility. Opposite to PVP, Crospovidone is insoluble in acid, alkali and common organic solvent. It has good physiological safety, hygroscopicity, insolubility and complexation capabilities, thus can be widely used in fields like pharmaceutical, food, personal care, feed, etc.
Pharmaceuticals: Crosspovidone can be used as disintegration agent, medicine slow-releasing carrier and hemodialysis film, etc., as it has an excellent chemical inertness and biological compatibility. After Cross Povidone absorb water, it provides very high pressure inside the tablet or capsule, then disintegrate them into small particles, thus improved bio-utilization of human body.
Brewing and Beverage: Crospovidone’s strong selective adsorption ability, it can effectively eliminate anthocyanin and polyphenol from vegetable drinks while maintaining the taste, thus improve the clarity, color and extend the shelf life of the drinks.
Household Chemicals: Crospovidonecan be used as moisture-preserving agent of top grade cosmetics, where it play the role of moisten skin, maintain aroma, ease pain and decrease pungency. Used in toothpastes, PVPP can not only clear the mouth, but also diminish inflammations.
