Polyvinylpyrrolidone CAS#9003-39-8

It is the cross-linked homopolymer of pure vinylpyrrolidone. It is hygroscopic and free-flowing white or off-white powder. It has a slight foul smell. It is insoluble in common solvents such as water, ethanol and ether. So its molecule weight range can’t be measured. However, PVP has ability to form complex with various kinds of substances (such as “Hu” class substance which can lead to the discoloration of a variety of wines and beverages discoloration). Also it is easily to be removed after filtration because of its insolubility.
