Product Details

Products Description of 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.

Product Application of Polyvinylpyrrolidone CAS# 9003-39-8

Polyvinylpyrrolidone is used as an adhesive in glue sticks; an emulsifier and a disintegrant for solution polymerization; an additive to Doro's RNA extraction buffer; as a liquid-phase dispersion enhancing agent in diffusion-ordered spectroscopy (DOSY) NMR and as a thickening agent in tooth whitening gels. It finds use in personal care products like shampoos and toothpastes, in ink for inkjet printers as well as in contact lens solutions. It is used as a food additive and in the wine industry as a fining agent for white wine. It is used as a capping agent to synthesize silver nanowires through a polyol process.
