Pvpp 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 cross link density and does not form gels that can impede disintegration, dissolution and drug release. It can be widely used in such area of beverage industry, pharmaceutical industry. Furthermore, pvp-p can also be used to improve solubility, and hence, enhance bioavailability in not only human but also veterinary applications.
